Question about Toshiba TP55F80/81 55" Rear Projection Television
I SUDDENLY LOST THE CONVERGENCE ON THE LEFT OF MY SCREEN. IT DOESNT CHANGE HOT OR COLD THOUGH. IM TOLD I NEED THE ORIGINAL REMOTE IN ORDER TO RESET THE CONVERGENCE. DOES THAT SOUND RIGHT? EVEN IF SOMEONE CAN GET ME THE PART # FOR THE ORIGINAL REMOTE WOULD BE HELPFUL.
The problem is probably that one or both of the STK convergence chips have failed. These control the convergence coils around the red blue and green guns and are the most common cause of sudden convergence problems and the protection circuit shutting the TV down when turned on.
I can post details of how I replaced these on my Toshiba 40WH08B. Yours should be similar.
