    I have had the "dmd" board replaced as well as the power supply and the main boards, we have bypassed the ballast as well, still continuous blinking red light. And we have tried a reset as well.

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

If the green front panel LED blinks continuously and the TV never comes on, its an issue with the "DM" board. When these TVs are first plugged in, the green LED should blink for 30 sec. to a minute or so. This is the TV booting up, reading its software. Mitsubishi has been having problems with this circuit for several years. In may cases the only permanent solution is to have the chassis rebuilt by Mitsubishi at considerable cost and inconvience. The chassis may have to be sent back to Mits for this rebuild. Call Mits and ask for help.

SOURCE: Mitsubishi WD-52525 52-inch DLP HDTV ywllow warning lamp light

that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours

What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away

or just simple replace the lamp. 915P020010

The lamp is either defective, not connected properly to the wiring or plugs (careful alignment required on the two connections), wrong type bulb, or the front panel is not replaced properly to trigger the panel sense switch (lower right side of panel)

Check your lamp. The popping sound was most likely the arc tube exploding. Make sure you only install a real Philips or Osram lamp. WD73737 Mitsubishi Genuine High Quality Original Projector Lamps now...

73 mitsubishi dlp tv 73737 has sound but no picture with red light in frount


You need a new lamp. The red light means the lamp failed to turn on.
You can find cheap ones on ebay for about $40. If you go to best buy they will charge an arm and a leg. You can change the lamp yourself and it will take less than 15 mins to do. The only tools youll need are a phillips screw driver and maybe a flat head.
