FP731 Benq LCD Screens Problem Is No Power

The BenQ LCD Monitor mannequin FP731 downside is no energy symptom. You probably have read my previous articles, you would know that I would not quick use all my testing gear to examine the entire energy and inverter board as an alternative I'd use my eyes to scan all the components first before beginning to use my digital multimeter to examine on the fuse and other elements first.

I saw about 8 filter capacitors that had bulged and leaked on prime of its capacitor casing. We have now the primary clue and if my assumption is correct, only the capacitors that brought about no power symptoms. Nevertheless with a purpose to be in the secure side we've to examine different elements as well.

Trying at the power main aspect did not reveal any burnt or cracked elements in the board. It isn't adequate just by wanting on the board, we must test few of the vital elements first with the intention to confirm that it is protected to switch on the facility after the alternative of the eight defective capacitors. The vital elements that I referred to was the fuse, energy or chopper fet (mosfet), change mode power provide primary winding and secondary diodes. When you have the experienced, you can examine the entire elements on board with out removing it but in fact the smps major winding you need to use a flyback tester to check it.

After all of the crucial components examined okay, I might presume that after the alternative of the faulty capacitors, I might instantly swap on the LCD Monitor with out connecting a light-weight bulb first. There isn't any crucial to attach the light bulb as a result of the ability facet elements were examined okay besides the fuse did not blow in the first place.

To your info, a lot of the capacitors used in the LCD power provide had been from the 105 diploma Celsius in order to last more and stand the heat produce by the ability supply itself. In case you change with an eighty five Celsius capacitor, it might not last long and will come back with capacitor problems again.

The Benq FP731 LCD Monitor problems was restored to normal operation after the eight filter capacitors was replaced. Capacitors breakdown was quite common in the LCD Monitor due to it compact design the place the heat have difficulty to transfer out due to the power supply board was coated by an aluminum shielding. Typically after few hours of operation, you could possibly feel the intense heat on the aluminum shielding and surrounding area. This can be a excellent news to us as an digital repairer as a result of an increasing number of LCD Monitor send in for repair because of capacitors faults only.

The best way to Restore Damaged LCD Laptop computer Monitors

The best way to Restore Damaged LCD Laptop computer Monitors

Whether you want laptop repair in Ithaca, or anywhere around the globe, should you own a laptop computer or an external flatpanel monitor, then you may have most likely run into some problems with the liquid crystal display.  If you haven't yet, then you definitely most likely will.  LCD problems are positively the most typical laptop computer problems in addition to exhausting drive crashes and unfastened energy connectors.  Cracked screens, strains on monitor, plasma effect, weak LCDs, dark pixels, backlight issues, and trembling LCDs are quite common.

Present are several straightforward tests to see what's unsuitable together with your LCD and to estimate the associated fee and bother needed in repairing the screen.  As a disclaimer, this is not repair recommendation, so don't attempt to service your laptop if you do not know what you're doing, as it's possible you'll likely produce more harm than there already was. Completely don't disassemble your laptop computer if the battery is in or it is secured to an influence source. 

Broken Screen

Not a lot to test here; you are going to need to interchange your LCD.  Your different alternative is to purchase an external flatpanel.

Markings on Display

This problem is most of the time precipitated due to a broken LCD or inside LCD video cable.  Generally when you drop your laptop computer laborious, it will possibly harm the LCD and the exhausting drive if it is on.  Plug the laptop computer computer into an exterior monitor or LCD television.  Does the image have strains?  If not, you both have an LCD cable or LCD problem.  Should you expertise strains on the external monitor (assuming the external is working well), you most likely have a graphics card problem.

Plasma, oozing, octopus ink, rising plume

It is extremely probable that your LCD is damaged and needs to be replaced.  This drawback is ordinarily induced by a bodily misfunction of the glass sandwich on the LCD.  Identical to the above test, examine to see whether or not or not you expertise a clean picture on one other monitor.  When you do, it's time for another LCD. 

Darkish, caught, hot, or in any other case abnormal pixels

These might be brought on by manufacturing defects which produce transistors to die or cease reacting within your LCD.  Typically you can repair a useless pixel, but in addition you can make the issue worse in case you are not experienced.  A secure try is to attempt to repair the issue with software.  Software comparable to UDPixel and JScreenFix can diagnose dead, hot, or stuck pixels and even attempt to fix them.  If these applications aren't successful, as a last try, you may try to gently pressure the affected space with an eraser to try to coax oil into or out of the pixel layers.  Furthermore, this attempt isn't guaranteed to achieve success, and may probably make the trouble worse, so be careful here.

Dim display

This could possibly be brought on by two commonplace points: inverter failure or backlight failure.  An inverter conditions energy for the LCD, and generally resides near the laptop computer hinges underneath the LCD case.  Inverters are harmful as a result of they generally run between 4-7 amps of current.  One amp can easily kill you, so don't mess with these if you happen to're not experienced with it.  If the monitor is ever bright, likelihood is your inverter is okay.  Backlights are difficult and dangerous to replace, so do not attempt except you understand how.  Most backlights are delicate and comprise mercury, a carcinogen.

No show

If you don't get a display in any respect, study it with a flashlight.  Maintain the flashlight at totally different angles to the screen.  If you happen to really can't see something, try to plug it into an external monitor.  When you get a smooth image, a number of issues could be amiss.  You could have a unfastened cable when you drop your laptop often.  The cable could be pinched in the joints and severed.  Seldom do you get a complete failure of the LCD, nevertheless it's possible.

Display works while booting, however ends working at some point

You in all probability have a software issue.  You should test the drivers and verify for viruses.

Show scrambles in time

This is typically caused by reminiscence troubles or an overheated video chip.  If reminiscence is the problem, you may try to take away one or two modules of RAM from the underside of the laptop, often behind a panel.  If this repairs the problem, time for a new stick of RAM.  If overheating is the issue, there are usually two causes.  Either the video processor is overheating, or all the laptop is overheating.  You will require to have the laptop computer taken apart to clear out dust, study all the fans, and study the thermal compound under the heat sinks.

Likom L705xxx Model, Dell Monitor Repair With No Power Symptom

This DELL 17" Monitor (Made in Malaysia under LIKOM model L705XXX, product no: L7055LP) came in with no energy symptom. Normally after opening up the cover I might have a look at the power provide (primary facet) for any burnt and cracked components first. If there are darkened space and burnt elements, I might tell myself that this Monitor wants a little extra time to repair it. If it's not (component's intact) I'd normally begin to discharge the filter capacitor and begin checking the fuse.

Okay, it is confirmed that all the first side parts appears to be like good on this Monitor.

First, discharge the large fat filter capacitor with a resistor (I do know that the voltage already drained off but it is a normal process for me as a result of what if the start up resistor has an open circuit?) then test the fuse.

If the fuse is okay, expertise will inform you that the bridge diodes are also working fine. Place your black probe of your analog meter set to x1 to the middle pin (drain) of the power FET and crimson probe to the other pin one after the other (gate and source). If the pointer of the meter would not kick then eighty % of the Power FET is okay. If you want to one hundred% confirm whether it is good then you need to solder it out and test. If the pointer shows a studying then most likely the ability FET has developed a short circuit. The result that I got from this Monitor was the pointer don't flick.

Now's the time for me to make use of the dick smith flyback tester to check the smps primary winding. The consequence that I bought was, the led bar do not lit. Ah ha! That was a clue and this clue tells you that it's either the smps major winding is shorted or one of the secondary diodes has given way. Of course you can examine all the secondary diodes with your normal multimeter first (keep in mind, every electronic repairers have their own process strategies of troubleshooting) but I favor this fashion as I wish to verify additionally if the smps primary winding is working or not.

Often smps transformer could be very sturdy thus I did not suspect it to drag down the flyback tester reading. I straight away check all of the secondary diodes with my analog meter and located one diode shorted (half number U202G). Since I would not have this half quantity, I use a UF5404 extremely fast restoration diode as a replacement. In truth I use this UF5404 to all 14 to 17" Monitor as a alternative for all half variety of secondary diodes. The spec of this diode was 400volt, 3 Amp with 50 nanosecond.

After the substitute of the diode, and putting the flyback tester probes once more to the primary winding, the consequence shows full bar on the LED. Don't be pleased with the outcome yet because your job nonetheless hasn't done.

Now I moved on to check HOT with the same procedure as checking the ability FET. The HOT checked to be okay too. Next, I verify the inner capacitance of the flyback transformer to see it is shorted or not or is the capacitance worth run. In your data, internal capacitor in flyback transformer gave lots of issues in laptop Monitor. I additionally scanned by the B+ FET and located it to be good too.

Now could be the time to change on the Monitor, nonetheless this spherical I do not connect any bulb as a result of it was only a shorted diode within the secondary side. I might solely connect a light bulb after restore when there's main quick circuit within the primary facet similar to a blown bridge rectifier, shorted fet and smps major winding and likewise burnt elements in the board.

The DELL 17" Monitor worked superbly and after lengthy hours of burn-in test, I declared it okay and ready to send back to my loyal customer. Is not it enjoyable to be able to restore a Monitor and on the end you get paid for something you like doing. I simply love digital repair!

713N Samsung LCD Restore with SE7889-Lf ic Problem - Owner's Guide

This Samsung 713N LCD monitor got here in with no show symptom and no power. In other words, when you switched 'on' you might see the facility LED lights up (no display) after which for couples of seconds the power led gentle goes off. After I removed the sign cable and switched 'on', now I may see the check signal cable OSD appeared at the screen. This proved that the inverter board, lamp and energy supply is working. Once more, I plugged in the signal cable, the show and energy LED gentle went off.

After opened up the quilt, I verify the on/off signal from the mainboard to the inverter board. With sign cable in, there was no on/off sign to the inverter board however when the sign cable was disconnected, you would see clearly out of your meter there's a on/off sign going into the inverter board thus the show appeared with the test signal OSD current at the display. From this check, it is rather apparent is the principle board problem.

To substantiate whether is the primary board downside, it's a must to use an identical Samsung 713N model to confirm it. True enough, after substitution with a known good board, the monitor is okay.

510bn Samsung LCD Power Supply Restore Secrets and techniques

510bn Samsung LCD Power Supply Restore Secrets and techniques

The criticism for this Samsung 510BN LCD monitor was no power, after the quilt was opened I found that the facility filter capacitor still hold some cost and the voltage was fairly high. A very good monitor by proper the filter capacitor saved voltage must be discharge in lower than 10 seconds. This means that there was something not proper within the circuit. When you occur to restore the sort of energy drawback, be sure you discharge the filter capacitor first earlier than checking on others components. After the filter capacitor voltage already discharged , I used dick smith flyback tester to measure throughout the primary winding of the swap mode power transformer to see if there are any quick circuit occurred.

The results of the take a look at was the flyback tester LED mild all goes off which means there must be parts shorted either within the major or secondary section, generally the primary winding can go shorted also. A shorted power ic (this monitor is using the 4 pins 5L0365R power ic) within the major section or a shorted diode in the secondary section would pull down the flyback tester LED bar to the minimum.

If the flyback tester LED have 8 full bars, which means that the parts such as power ic (power fet if have), energy transformer major winding and all the secondary diodes aren't shorted. To isolate if the shorts is both within the major or secondary section, you must desolder the power transformer. Examine the first winding of the facility transformer off board first before you take a look at on all of the secondary diodes using analog meter set to instances 10 Okay ohm.

A shorted diode will show two studying registered at the analog meter. On this Samsung 510bn LCD monitor power provide, the triggered of the no energy and filter capacitor take longer time to discharge was resulting from a shorted secondary diode which is from the schottky kind with the half number of SB5H100. Looking the web, I discovered this diode technical datasheet; it is a 100Volt 5A schottky diode. This shorted diode is situated at the 12 volt rail which implies it converts the ac to 12 Volt dc.

After the substitute the LCD monitor work perfectly fine! Whether or not you are troubleshooting the Samsung 510BN Lcd monitor power provide or any kind of change mode energy supply, basically the procedure of testing it's the same. Of course there are a lot of more strategies to locate the shorted secondary diode corresponding to immediately test the diodes, however this method can examine for components shorted even without touching the soldering gun.

This means, if the flyback tester proven eight full bars, then don’t waste your time to test on all of the secondary diodes again. Get one dick smith flyback tester and you could possibly see how worthwhile this meter is in performing variety test for you reminiscent of checking the computer monitor B+ coil, flyback transformer, crt horizontal yoke coil, ballast and lots of more.

Dell E151Fpb How To Restore LCD Monitor - No Display Problem Manual Guide

Dell E151fpb LCD monitor came in with the complaint of no power however upon carefully have a look at the LCD you could possibly see a very mild (blur) white flashes throughout the display screen and the ability LED will not be lit. Removing the quilt was a bit straightforward compared to different models. As ordinary each time the mainboard and energy board have been exposed, I would search for any bulged capacitor, darkened space, a loosen connector and etc. Nevertheless this monitor boards appears perfectly okay. The next step was to separate the ability/inverter board with the principle board. Power was utilized to the ability board and I might hear a soft 'chip-chip' sound. Once I measure the 12 volts line with a digital multimeter, the readout was about 7- eight volts which was very unusual. In reality this is excellent news to us because we all know what the subsequent step that we must always make.

Now we could use a 12 volt automobile brake light bulb to test at which section that is inflicting the low voltage output problem. If the LCD monitor designed to run on 18 or 24 volts then you might use a light bulb from the large trailer. A defective part in either main or secondary aspect might cause low output voltage. Removing the fuse as shown within the photograph and connect the bulb between the availability line and the cold ground may inform which part is giving problem. You might use this technique but first you should verify that the secondary filter capacitors, TL431 adjustable precision shunt regulator ic, optoisolators and parts surrounding the optoisolator is working earlier than you proceed to use the sunshine bulb.

When the facility is on the sunshine bulb nonetheless do not lit and the sound nonetheless could possibly be heard. This indicates that the first side is having drawback and we will go away the inverter/high voltage area and totally focus to find the faults in the major section.

That is the time to essentially test your basic electronics skill since you now know at which area the fault is and also you just have to make use of your skills to locate the precise bad component. There weren't a lot components in the major facet, and you may easily test all of them in less than 20 minutes. After checking all of the components I used to be surprised that all of them examined okay. Main winding of change mode energy transformer rings eight bars which signifies good and even the uc3842b PWM power IC replaced the ability still won't work! It was fairly difficult to troubleshoot this sort of downside where you are hundred p.c certain that the first aspect is giving drawback yet you possibly can not find out the culprit.

Since I had checked all the elements and couldn't find the fault, the one way that I could do is to direct change the semiconductor units such because the diodes, scr, fet, and transistors. From experienced I do encountered semiconductor parts breakdown when beneath full operating voltage. One by one of many semiconductor elements I replaced and energy on each time I had changed it to see if the bulb light up or not. Guess what, you wouldn't believe what have I just discovered-a defective 2N7000 fet! The moments I have replaced this fet and power on, the bulb instantly gentle up. I could not consider it was this defective fet that causes all the output voltages to drop! I was so joyful that I ultimately solved the problem and who knows this might be a typical fault for all DELL E151Fpb LCD monitor- so please take notice to all LCD monitor repairer.

I began to verify again the faulty 2N7000 fet with my analog meter and peak digital atlas part analyzer and the end result is still the same-tested good! Identical to flyback transformer, the very best testing tools to test Fet and different parts is actually the gear itself because it runs on full working voltage, frequency, sign and etc. What you've gotten just learned from right here was that if all of the suspected elements tested good, the one approach to reveal the reality is to direct change the parts. Hope you take pleasure in this article and more good articles to return on a regular basis! Wishing you all the most effective and completely happy repairing!

BenQ T705 LCD Monitor Problem in C5707 Transistor

BenQ T705 LCD Monitor Problem in C5707 Transistor - Repair Guide

This BenQ T705 LCD Monitor has a standard fault of display shutdown after few you "On" for few seconds. The cause of the problem was normally a shorted one or two of the C5707 push pull transistors. In addition to the shorted transistor, one additionally has to test the tuning capacitor for top ESR value with the help of ESR meter. If you do not personal one, you should utilize the digital capacitance meter to test the capacitance value. However, from my expertise, checking only the capacitance value does not guarantee that the capacitor is nice except you confirm it with ESR meter. The reason why I emphasis on checking this tuning capacitors was as a result of the capacitors have a excessive failure rate that might cause the C5707 transistor to go shorted. You even have to observe the high voltage transformer pins carefully. I had come throughout quite plenty of shorted C5707 transistors brought on by dry joints in pins of the excessive voltage transformer.

In this case, as traditional after I've confirmed that only two C5707 transistors shorted, I began to test the tuning capacitors and examine the pins of the high voltage transformer. Both the tuning capacitors found to be okay but there were dry joints within the transformer pins. Contemporary solder was utilized to the high voltage transformer pins and I'm able to "On" the LCD Monitor. Guess what? The Monitor has the identical symptom once more which is display shutdown after few seconds! I do not imagine it as most of the time it will certainly work as it is a common fault!

I started to recheck the encompassing parts which have connection to the C5707 transistors but found no faults in it. Analyzing the board many times did not reveal any improper soldering job. There have to be something that has gone flawed that had caused the LCD Monitor to shutdown. Deep in my coronary heart I don't suspect backlights drawback as a result of the C5707 transistors shorted was brought on by dry joints within the high voltage transformer. Beside, the backlights were fairly reliable for this BenQ LCD Monitor model.

Considering again, I purchased a brand new badge of C5707 transistors from my digital suppliers not long ago. The center pin (leg) is a bit shorter than the opposite two as proven from the photo below. I thought to myself would it be this badge of transistors which have drawback causing the display shutdown after few seconds? In fact I am unable to blindly suspect the transistors except I've some proof of it. The discovering begins..................

Testing the C5707 transistor with an analogue meter set to X 1 and to X 10 Ok Ohm would not seem to be it has problem. Evaluating the outcome with an original C5707 transistor did have some distinction in the X 10 K Ohm vary but the studying is acceptable from my years of experience in testing transistor. The only thing that I have never in contrast is the Hfe reading. I used the well-known Peak Atlas elements analyzer to analyze each transistors and I may clearly see the large difference between the Hfe readings of the two transistors. The original C5707 transistor has Hfe value of 379 whereas the brand new badge of the C5707 transistor has Hfe worth of 161! Ultimately I found the reply!

I did tried change the four C5707 transistors at one go with the brand new badge of transistors however the outcome was the same. Installing the transistors that have the Hfe studying of 350 to 400 solved the show shutdown problem. This circuit seem like it may well only work with the same sort of transistor that has the quite precise Hfe worth! That's why for such a Monitor circuit, many technicians hardly can find a appropriate replacement. In other phrases, even should you could get the substitution transistor which have greater Volt, Amp and Watt but different Hfe worth, you still won't have the ability to deliver the LCD Monitor back to life again. From the above take a look at, this Monitor circuit has voice out loud and clear that it solely need the same part quantity with the identical Hfe worth except you might have some related transistor substitute specification that is an identical to the unique one.

For my readers that are in this electronic repairing line, though a few of you might not be within the LCD Monitor restore, I hope you'll take up this data and apply it in your field. Who knows at some point you would have face the same drawback that I am going through and this article could easily assist you to solve your drawback fast. Have a great and a blessed day!

Dell E152Fpb How To Repair LCD Monitor

Dell E152Fpb How To Repair LCD Monitor

The criticism for this DELL E152Fpb LCD Monitor was when switched on has energy (LED lit) but no display. LCD Monitor is different from the CRT Monitor where you could feel the static on the front of the picture tube or hear the speeding sound from the high voltage produced by the flyback transformer. In LCD, if no display you will not be capable of know if the inverter board is working or not except you use an oscilloscope to point near the inverter board and the scope might display a waveform indicating the inverter board is functioning.

A faulty essential board could cause no display downside in LCD Monitor. If there is a problem in the principle board, it could not ship a "on" (enable) sign to the soft start circuit and no voltage will movement to the inverter IC thus no waveform produce by the high voltage transformer.

In the above case, after the quilt was removed, the very first thing I check was the vcc (provide voltage) to the inverter IC. This model is using the well-known TL1451ACN Pulse width modulation (PWM) IC-some most popular to name it as inverter IC. Pin 9 is the VCC provide input and it ought to have about 12 Volts when the facility is "on". Measuring the pin with my devoted digital multimeter, it reads only about three volts which indicates there's a problem in the provide line. It might be components which might be faulty that dragged down the road or it might be the swap mode energy provide itself that do not produce enough power.

As a way to find the reply as which section is giving drawback, the first clue was that the ability LED indicator lit and this show that the IC is supplying sufficient power to the circuit. Another clue was that the meter is registering about sixteen volts at the enter of the 2A fuse. Because of these clear answers, we can conclude that the change mode power supply is working fine. You can also use a 12 volt light bulb to confirm it. You could read my other publish on LCD Monitor repair articles which talks about utilizing 12 volt mild bulb for troubleshooting purposes.

I kept on asking myself, why the voltage drop to three volts after the fuse. Earlier than the fuse it reads about sixteen volt but after the fuse it reads only three volts! I did not suspect the fuse, as a result of the fuse can solely either sure or no and no in between. The first circuit that I checked was the beginning circuit but all parts checked to be okay. I even desoldered the pin 9 of TL1451ACN inverter IC just to verify it isn't this IC that pulled down the voltage.

This drawback actually challenges my troubleshooting and repairing ability, because virtually all suspected components already checked to be working. Even the beginning circuit transistors (C945 & A733) I direct changed, afraid they would breakdown when under load. The only element that I did not test was the fuse! Through the use of my meter placed across the fuse, as a substitute of getting low ohms or zero ohm studying I received 1.012 Kilo ohms! I've acquired a surprised and don't imagine that a fuse can actually go into high ohms instead of open circuit. I at all times thought that a fuse is either shut or open circuit. A fuse with zero ohms become excessive ohm thus the 16 volts dropped to three volts! I've came throughout lots of this sort of fuse however that is the primary time a fuse became high resistance.

Replacing the fuse only put the DELL E152Fpb LCD Monitor again to life. The lesson discovered from here is that do not assume that a part is all the time in a superb working condition. You have to confirm it with your meter and in the event you still suspect the component is giving drawback, merely exchange it with a identified good one and retest the equipment. Semiconductors can breakdown when below full working voltage.

HP F1723 LCD Monitor- How To Repair No Power

HP F1723 LCD Monitor- How To Repair No Power

This HP1723 17" LCD Monitor came in with the criticism of no power. Upon further inspection I could hear a mushy intermittent sound coming from the both front speakers. Because the audio system can produce some sound, this means that the facility supply must be working positive and it might be some bad parts situated at the secondary facet that had prompted the facility supply voltage to drop to not start. The ability LED would not gentle as a result of the sign was coming from the Microcontroller (MCU) IC. Which means that if the MCU didn't obtain the proper voltage from the power supply, it is not going to ship output voltage to the power LED.

As normal, to open LCD Monitor cover , one need to be careful of not scratching or leaving a mark on the plastic casing otherwise the shopper could not wish to accept his or her broken or badly scratch LCD Monitor. Once the cover have been eliminated, you need to remove another 4 screws (two at either side) in an effort to take out the power/inverter and the Main board. For some LCD Displays, the second you may have open the quilt, you could possibly simply take away all the boards.

The power provide and the inverter circuit are in one board whereas the Main board and the audio board are in separate board. As talked about before in my previous articles, I do not immediately start to troubleshoot and restore any board until I've scanned all the elements with my eyes first. The power provide/inverter board look very new and the obvious signal that I may see was two filter capacitors (1000uf 16 Volt) had a slight bulge on prime of its casing. I believe these bulged electrolytic capacitors that had prompted the facility provide not to perform properly. I've checked all other e-caps too however all discovered to be good.

Normally at any time when a filter capacitor located on the secondary side of switch mode power supply (SMPS) have a too excessive ESR value, the voltage will drop greater than half causing many circuits will not work. Since I already found the dangerous e-caps, I've to make sure that the secondary diodes (this LCD Monitor is using Schottky diodes) do not go defective or leaky too. Upon checking the Schottky diodes (half quantity are SRF20100C and SP10150) I discovered each of them to be working fine. Changing solely the two dangerous e-caps with a good one solved the LCD Monitor problem.

Now get this, if you want to be good in any digital gear restore, if potential analyze different circuits too. That means when you every time substitute only the fuse and the bridge rectifier you will not study something past that downside and you're going to get bored easily. Let's take my case for instance, after the replacement of the capacitors I'll often analyze different circuits too like finding out what kind of part numbers certain components are using, which type of the inverter circuit is belong to i.e. Buck Royer or direct drive?, why each backlight circuit are utilizing 4 ballast capacitors?, What number of backlights the LCD Monitor is using, what is the inverter IC half number, what is the supply voltage to the inverter IC? What number of LED bar lighted up when check on the secondary winding of the high voltage transformer? What would happen if I pull out one of many backlight (will it nonetheless work or shut down?). What's the brightness line voltage if set to minimum and most? It's a must to answer all of those questions if you wish to be good at LCD Monitor repair. You can apply this type of questions on other digital gear too. This is a steady means of learning learn how to be good in electronic repair.

I do not need you to exchange caps or fuse everyday without realizing how other circuits perform or what are the elements used in different circuits. Though to analyze different circuits take you plenty of time however I can guarantee you that the time you have got spent are value it. You will not be capable to go far when you've got set your pondering by simply altering parts and never knowing the surrounding. If you wish to improve in digital repair then you definitely need a change of mindset in you and only you yourself can make the totally different! Try this method and I consider troubleshooting digital or LCD Monitor repair will never be the identical again. Have an important and a fantastic 12 months!

Dell E173fpb LCD Monitor How To Repair Easily

Dell E173fpb LCD Monitor How To Repair Easily

Troubleshooting DELL E173FPB LCD Monitor with energy blink symptom is sort of easy if you understand the fitting procedure to test it. There are two sections in the monitor that may cause energy to blink. It's either major or secondary section or even sometimes each sections may be faulty. So to isolate as which part is giving problem. I used an automobile 12 volt gentle bulb (brake mild) and connect it between the 12 volt provide line and chilly floor with the fuse removed. If the bulb nonetheless blink chances may be very high the facility primary part have problem.

Do not overlook the other voltages line as properly such as the 3.three and 5 volts. If any components shorted that will get the availability from the 5 and 3.three volts, the facility also may blink. If the 12 volts bulb lights up we can assume that the power supply is working fantastic and something shorted additional down the road that makes the power provide to blink. If the bulb lights and also you proceed to check the ability part, it is going to be going to waste your time. You must now concentrate on the secondary part circuit such because the 4 transistors C5707 that drive the excessive voltage transformer in the inverter board.

Simply suppose these transistors like horizontal output transistor (HOT) in the CRT monitor that drive the flyback transformer the place it labored so onerous and possibilities for it to breakdown could be very high. Checking the four transistors off board found one in every of them have a shorted studying with an ohmmeter.. This transistor can get faulty by itself or it could possibly be some others components that caused it to develop a brief circuit akin to a faulty excessive voltage transformer but all of the 4 high voltage transformers checked to be okay with ringer and ohmmeter test.

Now, here is the key that I will reveal. If you simply change the faulty transistor only, possibilities may be very high the transistor or another C5707 transistor will breakdown again. Usually what a technician does is to test the opposite transistors with either an analog or digital meter. In case you use both meters to check the transistors then you've gotten missed out on the faulty transistor as a result of both meters will not reveal to you the hfe reading of the transistors. Just some digital meters have the hfe checking feature. In other words, it's important to use test the hfe studying of a transistor. Although you possibly can substitute the opposite three transistors instantly, why not we do some detective work to seek out the reason for the problem?

Using the Peak electronic atlas component analyzer, I might clearly see the different between a very good and a foul transistor. A great C5707 transistor has hfe studying from 320 to about 390 but the bad one reads 467! The other two C5707 transistors have studying about 350. In the above case solely two C5707 transistors were changed and also you save the opposite two. I had burn in test this LCD monitor for a lot of days and it labored completely fine.

Conclusion- Whether or not you repair the DELL E173FPB LCD Monitor or another model such because the E172FPB or E171FPB, mainly the testing method is the same. You could also use this testing procedure on different brand of LCD Monitor too.

Compaq 17" LCD Monitor How To Repair

How To Restore Compaq 17" LCD Monitor

The criticism of this 17" Compaq LCD Monitor was shutdown after few seconds to few minutes. That means the display sometime will shutdown in few seconds while someday it can shutdown in couple of minutes. When there is a show the picture worked completely good until it shutdown. The first thing one would usually suspect is the faulty backlight. For your data, a bad or a weak backlight may cause such drawback and dry joints may contribute to the reason for the fault.

Since I've a spare backlight, I swapped the LCD backlight with the working one. It's easy to do it, simply remove the prevailing backlight connector and connect the great backlight connector to it. I've tested one after the other the backlight and the consequence was the LCD Monitor still shutdown intermittently. This has proved each of the LCD Monitor backlights are okay! So now my focus is searching for any dry joints in the LCD Monitor.

I put back all the inner metal casing like authentic except the principle cowl and swap "ON" the LCD Monitor. While at my left hand holding the LCD Monitor, my right hand holding the shaft of the screw driver, I started to gently knock on the LCD Monitor inside metal casing with the handle of the screw driver. The second I 'hit' it, the LCD Monitor went straight into shutdown. Wow! From the test I imagine you'd have identified what's the reason for the LCD shutdown-it was dry joint.

Opening up the casing once more, you'll be able to clearly see three boards i.e. the ability/inverter board, audio board and the Major board. I solely suspect the facility/inverter board as a result of that is the board that controls the backlights. What I did was resoldered all the elements within the inverter area except the SMD elements because SMD components rarely have dry joints.

When I energy "On" the LCD Monitor and hit it with the deal with of the screw driver, the Monitor once more went into shutdown. I told myself "it may possibly't be" but anyway I have a very high confident that the fault should be within the inverter area and not in Primary board or energy board. Next, I fastidiously maintain the LCD panel and use a test pen to lift up the corner of the inverter board and power "On" the Monitor. Guess what occur? The Monitor did not shut down despite the fact that I 'hit' a bit bit laborious on the steel casing. This once more proved that the problem is somewhere within the inverter area.

I opened up again the metal casing and carefully scanned by means of the entire parts in the inverter area-it seem like I have already applied contemporary solder to it. It was only the feedback circuit which have SMD parts that I have never solder. I used a magnifier glass to verify if there are any dry joints in all of the feedback parts but I don't see any. I went ahead to resolder all the SMD parts in the suggestions circuit and power "On" the Monitor. To my stunned, the LCD Monitor no more shutting down irrespective of which means or how I tapped the LCD Monitor with the handle of the screwdriver. I put the LCD Monitor for a lot of hours of burn in take a look at and it simply labored great. I have despatched again the LCD Monitor to my customer and until now after couples of days there is no name from my customer.

Conclusion - Do not overlooks the dry joints in SMD components. Each half within the electronic board is usually a suspect. Hope from this article you may get some ideas about solving intermittent downside in LCD Monitor.
