Re: Amps replaced...still getting 3D pix. The amps are...
There should be approximately 8 to 10 fuseable resistors around those convergence ics. They should stand out as they are a bright yellow colour. You should measure a short over them. If none of these are faulty I would leave the supply to the convergence alone and rather check the +5V / -5V and +12V supplies used by the convergence logic ICS. A common problem is the - 5V supply also used for your HT-protection cct op-amps. These ics goes short and pulls the supply to ground. There is no protection on these before mentioned supplies and therefore the set is still switching on but with a convergence problem.

You Need To Replace The Convergence Is Either Out Of Adjustment Or Replace The Convergence Amps. It Is Not A Typical Do It Yourself Job And Will Most Likely Need To Be Taken To A Specialist. It Can Cost Anywhere From $300 To $450 So May Not Be Worth It To Have It Fixed. If You Feel Maybe You Can Replace Them You Can Either Ask Here For More Info Or Google It. Sincerely, Michael Scott
If the unit is chirping your convergence amps are out again,or you have a shorted Horzontal output transistor. Not likley for horz output to go out after convergence repair. If he did not replace the 6.8 ohm resistors along with the convergence amps the convergence amps would overheat and short out again.This would explain why the corner would not adjust out. Not a very good buisness practice on his part.Here today gone tomorrow?
This is a convergence problem. From your menu, go to Menu, Function, Convergence and then use you remote to try to adjust your colors. If you can not get them to line up this is a problem with the convergence board. The convergence amps (STK392-040 x 2)are internally shorted. These can be replaced or the whole convergence board can be replaced. It's cheaper to replace the amps, but more convienent to replace the board (especially for the less electronically inclined!! :)
Hope this help you out....
