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.

I have a yellow line on the right side of my Toshiba 50 rear projection TV and yellow shadows around people


It sounds like a convergence problem---go into the customer menu and select convergence---set should offer center and multipoint adjustment--in the multipoint look to see if the outer crosses adjust--if red or blue will not adjust somewhere--bad convergence IC's.

If the convergence on one or more color does not align using the convergence setup procedure, that means that one or more convergence ICs must be replaced, that is the reason why you get bad picture.

That means that the convergence ICs are bad and must be replaced, the job is about $200/$300.
