Question about Mitsubishi WD-52525 52" Rear Projection HDTV
Our tv is 4 years old and the Picture is wavy
in the past after the set "warmed up" the picture would correct itself, now it is wavy all the time some more than others but it does not correct itself.
What is the problem??
This is a picture of the DM Board in your TV. The wavy lines are tell tale signs of a failed capacitor. The capacitors are the cylindrical components on the board. One or more of them have failed. There is also a FMT Board with capacitors that could be causing this also so test them all. The DM board alone is 1000 bucks so it would be well worth it to invest in 50 bucks worth of capacitors and change them all out. Your boards would be fresh and good for another 4 years.
Your other option is to call a TV repair man and he would come pick up your boards and bring them back to his shop and test out the bad 3 dollar capacitor and swap it out and hand you a bill for 500 bucks.
Hope this helps you out.

Normally a wavy picture or lines/bars that roll up or down are caused by defective capacitors in the power supply. This defect allows 60 cycle hum to progress through the signal paths and will show up that way. These "bad caps" can often recover sufficiently so it looks like everything works OK. This should not be an expensive repair. If you can solder, you should be able to repair this yourself. Let us know and additional details can be posted.
