Question about Toshiba 42H81 42" Rear Projection Television

STK IC CHIP 392-110

My blue convergence on my Toshiba 42HDX82 is out of whack and cannot be automatically or manually adjusted. I see from threads here I need to replace my STK IC chips. On the Electronix website they are selling one version for 5.99 and another version (same number but with a O behind it for "original") for 13.99. Is there any difference between the 2. Also, it appears that I could subsitute an STK IC 392-150 instead of the 110 for longer life and less likely overheating issues. Is this correct?

I made the same repair in a Toshiba 42h81 I replaced the STK 392-110 and after a lot of searching found the cheaper ones last 6 month or so be sure to use Sanyo IC's and replace the resistors with them when the IC's let go they take the resistors out I posted my repair On my page if it will help you dennisgm052.weebly.com

The color is messed up. the color is all different colors like red,green and blue.


Your convergence is out of whack.

This can be caused by a failed convergence IC - or can be adjusted using the Convergence settings in the main menu.

I have sony tv kp-65wv600. It has problems. color and video is blurry, double vision, letters are curved


You have a convergence failure.

Convergence IC failure is very common. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless

It could be one of two things: Either a bad solder joint or convergence IC failure.

When I try to do the manual converegence on my sony kp51ws510, I cannot get the squares around the + to change to red or blue and consiquently I cannot adjust the convergence. Flash focus works fine but...


You need to replace the convergence IC, They start with STK make sdure you get original stk IC's and not cheap china made or aftermarket parts as they will not lasts long in your set. if you pay less then 15 bucks for your IC that really is no bargain cause it is most likely an aftermarket IC
