I have a Mitsubishi 55"


This set has a convergence problem. You should only need to replace the IC. Part is STK393-110. It sits on the middle board behind the large heatsink. Use a heat transfer compound to ensure repair lasts. If you have no experience soldering (or unsoldering) please use a professional for the work. The traces are fragile and I have fixed many mistakes local DIYers have committed. Goodluck.

LINE ACROSS TOP OF SCREEN-LOOKS LIKE A GASKET


I have the same problem with the gasket dropping from the top of the screen. I took the back casing off (approximately 16 screws) don't forget to take off the adaptor box with two screws. and the additional 8 screws located at the bottom of the panel casing. After that the back panel will come off. Remove the tv screen from the front casing, approximately eight screws. Be careful not to dislodge any wires while remove the screen. Finally remove the gasket. All of this can be done at any local tv repair shop for about $150 dollars.
