Most likely the formatter board. Are these lines across the whole screen?

I have a Mitsubishi WD-62525. In general the picture is great from all sources (cable, component, and hdmi). However, there occasionally are very thin, horizontal lines that flicker across the screen....


I have seen this problem before. It is usually caused by a malfunctioning color wheel. Replacing it should resolve the problem. Let me know if you wish to fix it yourself so that I can find you a replacement.

Mitsubishi WD-62525 TV will not turn on


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it for a samsung ,it works like your mitusibishi:http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php The ballast has a sensor that detects when it's not able to power the lamp or if lamp is not responding,it will flash red when that sensor detects that.When you say: "it began to roll like the vertical and horizontal hold did not work then the sound went out" Do you mean you where getting horizontal lines? If you did that could be the Dmd.his is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Usually when there's a green light it could indicate a problem with the power supply,sometimes some capacitors do go bad. Check all of this and comment on this answer to see how it went.

Mitsubishi WD-62525 BLUE SCREEN NO PICTURE NO SOUND


I had the same problem and I found that it was 2 caps on the power supply board. I had both caps replaced and it worked perfect. While it is apart see if any other caps are bad( if they are puffed up in the center they are bad).

Vertical lines showing in picture, especially noticable on black


in these issue you can see vertical lines due to filter capacitors bad in the secondary power supply. 100micfarad/j35volts, 220microfarad/25volts.

I get lines running across my television (wd62525), especially noticeable when screen goes black. video noise? and it moves horizontally across the screen.


Sounds like interference or signal contamination. Does it occur on OTHER inputs? If not..then the input signal is corrupt, weak, has interference, wrong cable, or othewise defective.
