  • Open the front panel by pushing on it. Pressing on the panel releases the lock and allows the front panel to pop open slightly. Pull the corner gently to open the panel completely.

  • 2

    Use a pointed object, such as the sharpened end of a pencil or the tip of a paper clip, to push the "System Reset" button.

  • 3

    Wait about one minute, or until the green LED light on the front panel display stops flashing.

  • 4

    Turn your television back on once the green LED light turns off.

    this is procedure for most mitsubishi dlp.

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

What is a dmd on a mitsubishi 73" tv


Howdy Mike-d. here,
I do not know what a DMD is on a Mitsubishi 73'' TV.
I did do a little web searching and here is a couple of things I came across.

From this website: http://www.tvserviceparts.com/Mitsubishi_DMDChips.html WD73833 ALL 4719-001997 DMD Chip, DLP, 1920X1080/XHD5, 0.65"/ DC4, TYPE X NON
I have no ties to these websites.
"I researched this and it was a DMD chip that needed to be replaced."
from this website: http://www.consumeraffairs.com/home_electronics/mitsubishi.html

Hope that helps.

Mitsubishi 73" DLP powers on, through welcome


If you are getting at turn on source and back ground is all blue the set will shut down rather quickly;

I have a suggestion, if it works fine, and if not it will not hurt anything.

with original Mitsubishi remote turn set on and then Menu, 1,2,3, enter.

This is the soft reset that most of these sets have (cannot be sure since Model number above is correct?)

The reset button on the front (if it has it) just shuts the set down and reboots the DM unit inside.

Most of these sets when it is pressed the green light will blink for about 70 seconds and go out; that is the DM unit rebooting and the soft restart is something else.

Let me know what you find before you rate this information.

I bet you are using a cable box or satelite receiver. If so check for aspect buttons on the remote that control these devices. I know comcast says "HD Zooom".
