Question about Toshiba 50H72 50" Rear Projection Television

1 Answer

Toshiba 50H72 Rear Projection Television

Okay, I have a convergence problem with my televison. I know this because I had a projection television before I bought this one adn the same thing happened. It was working fine until this morning and then when I came home for lunch, the bottom half of the picture was messed up. I turned the TV off until I got home and the picture was the same. The red and the blue appear to be fine, but the green is wacked. I called a repair man and he said it would cost 600 dollar to fix it over the phone. Is there anyway to pin point the problem or a way for me to fix it myself?
