Question about Mitsubishi WD-52525 52" Rear Projection HDTV

Mitsubishi with no picture

When I turn on my tv all I get is fine lines with a solid pale yellow background color. I have sound, but no picture. We replaced the lamp not long ago and it still reads good.

Hi Genaro,

Blue led light lit solid and yellow led light flashes is an initial attempt of the set to re-light the lamp.Red led flashes and yellow led light solid means that the lamp won't light up that's why it only has sound without the picture.
Since you've replaced the lamp twice and still the symptoms persist, I suspected that the fault came from the ballast board and not on the lamp itself. If the ballast board gone to malfunction, there's no high voltage will produce to light up the lamp and will sensed by the processor and trigger the error code (Flashes/solid led light with color code).

To verify whether the ballast board is faulty or not, check if the lamp will lit by looking through the lamp door louvers at the rear of the cabinet upon turning on the set.
Please let me know what you will find to assist you further.

The picture on my tv is completely dark, but the sound is working fine. how can i fix the picture? because it's a fairly new tv


Hello
Keep a close look to the screen, and see whether there is any trace of picture on it. If it is there, you can see pale shadow of it moving. If it is there, be sure that the backlight is not there. Thhere is an inverter board to energise the CCFL lamps used as backlight component. If the inverter board got faulty, the CCFL lamps won't light up, and no brightness will be there with LCD TVs. Check it. OK.

Hi,Yes your problem sounds like the DMD board.This 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. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Video turn pale green/yellow then comes back?


sounds like your picture tube is going out, if its an old tv it would be best to let it die since its very costly to fix these problems. If its new you better get it looked at. It is a hardware problem, nothing you can do about it.
