I have a Phillips 26 inch widescreen flatscreen tv. Model number 26PW6341/10.

When I first turn it on the picture looks great. But once it warms up, about 30 min the screen zooms in all by itself and I can not change it back. Im not sure what to call what happens. Sometimes If I hit it on the side the picture will go back to the way it is supposed to be for a while. And if I leave it on it switches back to the way it is supposed to be also.

Okay, I think it has what is called a pincushion effect.

Bad solder joint(s), crack in a board, or a physically intermittent "part." Neutral

Okay, that is what I thought. I discharged the crt and then turned the board over to look and see if I could locate any bad solder joints. There is a part of the board that looks a little burnt but Im not 100 percent sure how to locate a bad solder joint.
