Question about Toshiba 57H83 57" Rear Projection HDTV
There are two IC's in your set that need to be replaced. These are convergence IC's. They have stk letters and some numbers on them and they stand up on a metal heat sink. If you know how to unsolder and solder on solid state printed circuit boards then you can replace them as long as you are carefull. These solid state sets are really super unforgiving if you slip and touch or short something together as there is still voltage in them even when they are unplugged. if you havew no electronics training, I would recommend that you seek out a trained tech to repair this set for you. It should not exceed more the a few hundred bucks and some peeps do it for even less.
