Question about Apex Digital GB55HD09W 55" Rear Projection Television
I have a similiar problem about the convergance box that has already been posted but my green image is to far to the right. when I go to adjust the blue and red the screen shakes and cause a double image of the green. I have saved where I was at in the adjustment but when I turn my tv back on it doesn't save the location. I located the ICs on the circuit board I and I didn't see any cracks in any sodder on the boards. The ICs are marked STK 392-020. I just wanted to know if I am looking at the right ICs and how I can fix this Problem.This has happened before and a repairman came and soddered some cracks. It has been less than a year and I am facing the same situation.
If you know how to solder and unsolder and understand the circuitry of a tv set, then those are the IC's you will most likly need to change. I would look at the fusable links on the board also. If you dont have the training for TV's, this is not the place to begin experimenting with. good Luck
