How to repair soldering on lcd monitor problems in easy way

FOR IMMEDIATE RELEASE
Metairie, Louisiana, United States of America (Free-Press-Release.com) October 11, 2010 -- Last month, I had received approximate 2~5 nos of faulty lcd monitors everyday from customers lived in a residential area occupied by 20000 people. I have never got such a good harvest indeed. How much wages do I get from lcd monitor repair only? Unbelievable! It is $6400 roughly which calculates from average $80 x 80 nos lcd monitor.

I can tell you that approximately 40 percent of total faulty lcd monitors are easy to be repaired normally and the rest is a bit time consuming but it is worth to perform electronic component analyzing, testing and replacement. Once you got the culprit, you solder it out and replace the new part and solder it back on the lcd monitor circuit board.

One of the most important and essential techniques in servicing lcd monitor is the SOLDERING technique which will bring you fast dollars easily and quickly. I believe most lcd monitor repairers will agree with me.

Let take few real soldering examples as follows:

Case 1: Compaq lcd monitor FP731 shutdown from few seconds to few minutes
Solution 1: Re-solder the feedback circuit of the ccfl inverter section C215, C216, D201, D204, R215, R246, R218, D206, C242, D210, R234, R243

Case 2: BenQ T705 lcd monitor got display shutdown after power on for few second
Solution 2: Solder out 4 nos. shorted C5707 transistors and solder new transistors back.

Case 3: Dell e151fp lcd monitor ( equivalent to Acer FP553 Chassis ) No power or power on then shutdown shortly
Solution 3: Solder out the faulty C605, C707, C703 capacitor, the faulty power ic UC3842B, faulty resistors R613, R623, R615, faulty transistor Q601, faulty diode D604= 1N4148 and fuse F601. Solder the new parts back into the circuit.

From above examples, no matter how severe fault level of lcd monitor, the soldering work is always involved in repairing lcd monitor. You can find the following articles explain the basic soldering to advance soldering technique of the surface mounted devices (SMD) on our website.

1) Tools for soldering

2) Soldering safety and health

3) Photos for soldering dry joints on circuit boards

4) Basic soldering technique

5) Advanced Smd soldering technique

6) Quick and inexpensive soldering station

Once you master the soldering skill, you can apply this useful skill to fix the fault electronic component on any circuit boards. Start practice and practice make perfect.
