Wavy picture When I turn on TV the picture is so wavy it is unviewable. After about 10 minutes it would gradually clear and was fine. Now the waviness never goes away completely. TV is approx. 1.5 years old. This problem started about 5 months ago.

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.

I have a Toshiba 42H81 with the same issue.
5+ years old. Paid $1450 and got great use out if it with no problems.
wavy picture started slowly about 2 weeks ago.
Is this a complex fix for a typical repair service? Anyone know what a fair cost to repair is for this issue?
Thanks

SOURCE: bad picture until tv warms up

this is a very common occurance in these sets. toshiba has issued a servece bullteen with this set. Sorry to tell you this but this is a problem with some very small capacitors on what is known as the hypermodule. in my shop we fix 2 to 5 of these a month. you really have to know how to solder. Idealy replace the hypermodule is the best way. but......that board is hard to find. so we replace these 11 very very small componets with twezzers and a big magnifier. we charge about 250 to 350 for this repair.

Toshiba/ 42H81 / hyper board

You can either yrplace your Hyper board, or replace all the serfice mount capacitors in it. The cap replacement fixes this 90% of the time.

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).

Hello,

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

The solution to that is to replace the light and your television will be in good condition once again.

Wavy picture

It looks like you have a convergence problem here, probably a defective convergence IC.

It is capacitors in your TV set. If you fix it before the set goes out, you will save about a grand. Contact me @ [email protected]

Wavy picture for Toshiba Model 50H12 Rear projection TV

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.
