    I had the same wavy picture. It started out lasting only 10-15 minutes, but now it lasts all the time.

    I'm also trying to find a solution to the wavy picture for my Toshiba 50H12.. It started out lasting about 5 minutes but now takes about 15 - 20 minutes to go away. I wonder if it is soon just going to stay that way?

In general, these problems are usually caused by leaky output filter capacitors in either the low voltage power supply or, depending upon the type of waviness you're attempting to describe, it could be in the vertical deflection circuits (either the vertical oscillator or vertical amplifier). I would estimate cost to repair from $200 to $350 dollars, depending on how long it takes to find the problem. It most likely though is a component issue in the circuitry.

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).

The problem with the television is the lamp. It is faulty that is why the screen turns wavy in minutes.

Wavy picture

this is caused by a bad convergence module, and there are probably some dried out electrolytic caps in the circuit as well. i have one in the shop right now that came in with the same problem. if you have it serviced, make sure they replace all of the convergence modules (there are usually 2, but sometimes 3 of them), because if one went bad the other(s) is likely to go out soon as well.
