I have Mitsubishi WD-62525. Last week I turned TV on and there was no picture, on green horizontal lines across the screen. The picture then went black and I only have sound. The lamp indicator lite turned red and the TV shut down. This week I replaced the lamp with a new one. The same issue is occuring, black screen, lamp indicator light is red, still has sound and the TV shuts down on it's own after a few minutes.

I have the same problem...

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.

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.

Hello:

Make sure u replace the lamp cover as the safety switch need to be closed to make the set work. If new lamp did not repair your problem , then it may well be the Ballast Board, Sometimes call the Lamp Driver.

not bulb component is damaged in power supply serction shutting down to protect other components

The green CRT's (color picutre tube or color wheel, or ballast) will need to be tested for replacement.
It is quite common with these tv's

You will need an ohmmeter and or voltmeter and test each component for currency and accuracy

The capacitorson the FMT board have failed, which will cause that symptom. Is the menu screen clear when you hit menu?

My Sony had the same problem. Unplug from the wall for 36 hours and it should solve the problem

I have the same problem with my tv, my tv tech said mitsubishi knows of the problem and knows how to fix it, but it would cost me 700.00 plus his labor to take out the chassis and send it in to mitsubishi, plus I would be without a tv for up to a month. this is b.s.

sounds like bad capacitors on the FMT board need replacing that is a common fault with the first generation DLPs There are 3 bad capacitors.
