Toshiba 56H80 Convergence Problem?

I have had my Toshiba 56H80 Rear Projection HDTV for quite a few years with almost no problems at all. A couple of days ago, my picture started to show blue/green shadows. These shadows are the worst in the top left, bottom left, bottom right....I tried the convergence adjustment, you can pick certain positions on the screen to fine tune the convergence....The blue + will not move in the places where the convergence is off the worse...What is the problem with the set? Any help you can give me would be greatly appreciated.....Thanks in advance....

Re: Toshiba 56H80 Convergence Problem?

There are 2 large IC's in your set and one of them has burned out. These are called convergence output IC's and are usually the STK392-010's. A good idea would be to go ahead and replace both with the newer, upgraded STK392-150 IC's. A good tech can change those IC's in about an hour and a half, and when I do a housecall for a set like that I charge $150, but shops in your area will vary so be sure to ask around.

Horizontal Curvature with convergence problem

DA, convergence circuit has failed, the IC`s and possibly a couple of support resistors need to be replaced, your right about it being a good set, 6 years is about average for convergence IC`s, call your local shops for a few estimates and get it fixed, it will run for a lot longer than 6 years, hope this is the advice your looking for, e-mail me if you have more questions, BMW Rider
