Question about Mitsubishi WD-52525 52" Rear Projection HDTV

WD-52525 Shuts off, shows red lamp light even after replacing lamp

I turned on the TV, it strobed lots of colors at me but the menus and stuff were reduced to dancing monochromatic icons. Basically.. everything looked totally jacked with no video showing up and then it shut off leaving the red lamp light on. I thought it was finally time to replace the lamp, so I installed the new one that I bought over a year ago. No change. After resetting the system and unplugging and everything I could think of, if it even came on at all, it would flicker and shut off again. Mitsubishi won't help. They only warranty the lamps for 30 days (wish I had known a year ago). I got a Bravia in the meantime while I research this problem and try to get it repaired.. Any insight would be appreciated.

    Yes I have same problem. Started out as a weird looking picture after startup and then progressed to a solid red lamp led. Code is 34 when I push the menu and device buttons. New Lamp has same symptom. No bent pins.

I have a Sears Teh over right now, in teh same position. They noticd that the original ballast is OSRAm, while the replacement ballast, which he said is very common, is a Phillips. He is checking voltages on the exhaust fan, from what is seems. No luck.... Now, there is an orange light flashing after everything trys to boot up, whenbefore it was the steady red, showing LAMP. Also the error code was for lamp/bulb abnormality too, before the ballast was attempted to be replaced. Since this is visit # 2... I am hoping the next one is unsuccessful as well.. so I can get the value of whatever,a nd apply it towards an LCD TV. Since I use the WD-52525 52" TV as a monitor too, the LCD will not need these damn bulbs, and have a better contrast for reading text against a black backround.

Turn on the set and let it shut down. push in the Menu and Device (or input, I don't have a schematic in front of me) buttons on the front of the set at the same time and hold until the green light starts flashing. Then release. There will be two different sets of flashes, such as, 3 and 6. The code 12 means the set is opperating fine. The other codes will tell you what part of the set needs repaired. Also, remove the bulb and check the ballast connection to the bulb. I find the connection for the bulb bent over when a customer replaces the lamp sometimes. Let me know what you find and we can go from there.

    The code 34 means a lamp abnormality. The most common is of course the lamp.
    If the lamp is new and the ballast connections are not bent over, then the next probable part is the ballast.
    I check for voltages and signals going to the ballast and if they are there, the ballast is bad.

maybe your problem is in the power supply circuit of your tv,but then try to replace the flyback first maybe there is no high voltage coming out on the cap.

Mat not working in dance mode

We found the solution on another post:
"Try making sure that the DDR mat is plugged into the FIRST controller jack (there are 4). That is the only way that it is associated with controller 1. If you plug it in any of the other controller jacks, you will be able to use the mat with instructions, configuration, etc., but not to dance. Hope this is your problem! -GeoffM"

Good luck! This worked for us!

Loss of colour

Hello judithprust

The IC (integrated circuit) that controls color might be bad or the filter for the color burst might be defective. In either case a qualified TV repair person should be enlisted to fix this problem. The color burst signal uses vector mathematics to control the color output of your device, it the color burst is removed the picture will display a monochromatic (black and white) picture.

Thank you,

Color problem after warm up.

The probelm is caused by either a bad color wheel sensor, color wheel or formatter board. I have the new redesigned sensor assembly and color wheels that I can sell. It is best if you send me the projector for proper diagnosis.
