Question about Toshiba 50H72 50" Rear Projection Television

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?

1) pull chassis 2) replace both Stk's for reliable repair

3)re-assemble 4) re-align convergence

If you hire a technician, 400.00 is ave. price.

I'm having the same flickering issue with my Toshiba 50H72, I'm having the same issue with my Toshiba 50H72, constantly flickering, like a power problem, however, it almost completely clears up when I switch the input to a HD input. Any idea what I can do to fix it? Is there some part that I could replace to fix this? I don't want to buy a new set yet, if it's a minor repair. Thanks, Larry

Toshiba 50H72 no picture, no sound Bill, Saw a solution from you on the message board and I'm hoping you can help. I had a convergence problem as noted by many folks out there. Replaced the two IC's and an obviously blown resistor. Unfortunately, now I get no picture, no sound, just the red power light. Nothing in the back looks obviously blown or damaged. Please advise on where to go from here. Thanks! Frank
