The best way to Repair Soldering on LCD Monitor Problems in Simple Way

Last month, I had obtained approximate 2~5 nos of faulty liquid crystal display monitors everyday from prospects lived in a residential area occupied by 20000 people. I have never bought such a very good harvest indeed. How much wages do I get from the restore only? Unbelievable! It is $6400 roughly which calculates from common $80 x 80 nos lcd monitor.

I can inform you that roughly forty % of whole faulty monitors are easy to be repaired normally and the remaining is a bit time consuming but it's value to carry out electronic component analyzing, testing and replacement. Once you bought the culprit, you solder it out and substitute the brand new half and solder it back on the circuit board.

Some of the necessary and important strategies in servicing lcd monitor is the SOLDERING technique which is able to carry you fast dollars easily and quickly. I believe most repairers will agree with me.

Let take few actual soldering examples as follows:

Case 1: Compaq FP731 shutdown from few seconds to few minutes

Solution 1: Re-solder the suggestions circuit of the ccfl inverter section C215, C216, D201, D204, R215, R246, R218, D206, C242, D210, R234, R243

Case 2: BenQ T705 got show shutdown after power on for few second

Resolution 2: Solder out four nos. shorted C5707 transistors and solder new transistors back.

Case three: Dell e151fp ( equivalent to Acer FP553 Chassis ) No energy or power on then shutdown shortly

Solution three: Solder out the faulty C605, C707, C703 capacitor, the faulty energy ic UC3842B, defective resistors R613, R623, R615, faulty transistor Q601, faulty diode D604= 1N4148 and fuse F601. Solder the new components back into the circuit.

From above examples, no matter how extreme fault stage of lcd monitor, the soldering work is all the time involved in repairing liquid crystal display monitor. You can find the following articles clarify the basic soldering to advance soldering technique of the floor mounted devices (SMD) on our website.
