Toshiba 50H12 Rear Projection TV wavy screen

Hi, so here is the problem, I hope you can help. For a little while when I would first turn on the TV the screen was very wavy and distorted. After letting it warm up for a little while the picture was fine. However, the problem has only gotten worse now and no matter how long you let the TV warm up for, the picture does not get any better. The weird thing is when we hook up the TV thru the component hookup, the picture is still a little wavy at first but then after it warms up, it is fine. I have no idea what I need to do...I am a single mom with two kids and can not afford to hire a repair tech if I really don't have too!! Any help would be greatly appriciated.
Thanks in advance!!

There is a Hyper Module mounted right behind the video inputs board. in most cases you can replace the 10uf surface mounts carefully not to tear the foil. and the set will return to normal. or replace the H/M board. this board is soldered 4 tabs on bottom of main board and then pulls out. good luck list of caps cz52(may not have this cap).. cx261 cx270 cx230 cx178 c514 cx221 cx250 cx241 cx541 cx670

Toshiba 42WH36P rear projection TV has wavy lines

the problem is going to be a bad NEXT HYPER UNIT module. this is the digital scan card in the tv. try using the componenet inputs and if the tv works ok then you know that the HYPER UNIT is the problem. the reapir process for a "do-it-yourselfer" is too involved and would recommend a serivce center for this repair.

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.
