In order to do this you have to be very good with technology and you have to know what you are doing because if you slip up once, you make a mistake and touch a part that holds a charge even after unplugged and you may get shocked. This would be best done by a professional so that it will be completely correct and the chance of danger will be lower.

Most of these Philips sets use two STK-392-120 convergence IC chips; if you can locate them inside look at all the little blue resistors to the left and front of them---these are feedback (protect) parts---if any of them are discolored in the middle--not powder blue but somewhat white in the middle---you have a bad ic and both need to be replaced---most of the protect resistors are 6.8 ohm in value. If this has been helpful give me a vote.
resistor along the convergence are 2Watt size or less. they are easy to find as all of them are in pairs. if you find one is not the same on the other, then replace that resistor. change the 2 convergence IC at the same time. let us know.
You have a convergence problem. Here are some of the most common symptoms.
Screen looks 3D One or more colors can't be adjusted when when using the convergence menu. Screen is bowed in but stationary.
Solution: You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix.
Replacing only the ICs MAY solve the problem, however, many people have also had blown resistors requiring replacement. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice. You do not have to replace any transistors to fix this convergence failure.
i have tried this replacement on philips 43 inch. convergence ic part # is STK-392-120. it is mounted on a big heatsink, replace this 2 IC at one time. soldering is not difficult.
1. you need desoldering tool (**** type)
2. soldering iron of 40W
3. and silicon grease for greater transfer between IC body and heatsink.
i bought that personally in asia for less than 50USD on two IC with same part # .
let me know if there is any other thing i can do.
Bull!!!!!!!!! i dont think he knows what hes doing.... you can send the board into ptscorp.com have them check it out, it's the board with big black iC stk392-XXX send that one in, you convergence is done thru the menu system.
