Question about Toshiba 50H72 50" Rear Projection Television

1 Answer

Wavy Screen on Startup

When we first turn on our Toshiba 50H72 the screen comes in unclear and is all wavy. After about 15 minutes or so after the TV seems to warm up, the picture is fine. This problem has continually taken longer to fix itself, and now seems to take 20-30 minutes for the screen to be viewed. It still jumps here and there, but you can still watch TV. Can you please give me a solution to our problem?

    I have the exact same problem - and also a Toshiba 50" Projection tv. What is the 60Hz problem you described?

I gather from your post that wavy can mean two possible things as the TV comes on, you see the picture flow like ocean waves? In this case you may have 60Hz hum modulating with the picture, this is actually unlikely these days, but I have heard it happens sometimes. The other thing it could be is light horizontal tearing. This happens when the horizontal frequency is too high or too low. You are not going to like my solution because I feel that for problems like this the set must be analyzed not just subjected to "shotgun troubleshooting", so here I go, Take the TV to a repair shop.

1. "wavy" may mean a signal problem inside the set--are you seeing colors out of position or skewed around letters etc?

2. Does it do it when a DVD is played? (this will rule out certain things).
