The DM boards for that chassis are almost impossible to find if they are still good. Have you tried replacing the caps on the DM board that you have? Thats usually whats wrong are bad caps.

Testimonial: "Hi. Thanks for the info. I did find one cap that domed and replaced it. Not knowing that you had to wait and hit a reset button. I ordered 12 caps that are mentioned in other posts. We'll see what happens then. Thank you again."

SOURCE: WD-52725 Timer light is blinking and will not stop.

This part will cost you about 650 to 800 bucks my friend. if you have any soldering skills, and can follow directions, I posted a DM board fix. it may just be four small capacitors. Now this set that was used in the fix is not exactly like all the other Mitsubishi TV sets that still have a DM board, but if you can locate the DM board, follow the rest of the repair. if you do not know how to solder, do not take a chance, as this part is way too expensive to be experimenting around with. Get the Capcitors(there is a link there too for the capacitors)and take the DM board to a service shop, as this should not cost you a lot to have a pro do this for you.

SOURCE: mitsubishi wd-62825 dlp

The WD62825 has a Digital Module located on the left side of the chassis looking at it from the rear of the set. It's housed in a metal box that can slide out of its holder after removing the trim screws.
The module has its own power supply board and there are a group of 16v/1000uf caps on that board which commonly fail causing the constant flashing standby light. Further back on the module is a small board about the size of a matchbook called the E2P module. Its SMT (Surface Mount Technology) caps also commonly fail which can cause the same symptoms. Techs can tell whether the E2P has failed by simply removing it, hooking the DM back up and trying to power the set. If it powers on the picture won't be much good - but at least you can tell what's keeping it down...
Back to the caps on the pwr board. If they've failed they usually will buldge visibly on top. And ESR is almost not necessary. In any event that's the nuts and bolts on this model.
Is it a job for a layman? Yes and no - you might strongly consider a tech if you don't feel comfortable removing all the connections that the DM has with the signal board. There are about six - multi-pin - wired connections to unplug and then sliding the DM out of the unit and carefully removing the screws and latching to take the DM top cover off...
Hope this helps.
Bill

Did your replace lamp come on the screen or did you lose picture? Just because the LED indicator suggest replace lamp it doesn't mean it needs it. If your pix was dull or loss of brightness then replace it, if not then just reset your lamp timer, check your owners manual for instructions.

SOURCE: mitsubishi wd 52725 lamp troubles

You can use Mitsubishi 915p020010 or Osram E023. Remove the front and clean the lense using only a clean microfiber cloth. dirty lense main cause of dark picture. The lamp could be incorrect wattage.

SOURCE: Mitsubishi Model WD-52725 timer green light blinking fast

My Mitsubishi WD52725 will not turn on...the timer light is blinking. We pushed the reset button, unplugged tv. Just got off the phone with Mitsubishi customer "service." After answering numerous personal questions, and being on hold for several minutes, I was told that the only solution was to push the reset button. Duh! We'd done that several times with no change, which is why I called them! BIG WASTE OF TIME!!!!

We replaced the V26 dm repair kit and the problem still exists-tv won't turn on . What do you recommend?

Did you also replace the power capacitors on the power board. Usually the DM board and Power board caps together will cause the steady blinking led the DM caps alone only rarely cause the steady blinking led usually its a combination of both boards capoacitors failing.
