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 power/timer led is the one blinking constantly
the most likely problem is two 3300 mfd caps and 1 to 8 1000mfd caps on the power board.
could be the DM board or caps on it as well.

it is common for a cuircit board called the dm(digital module) to go bad in these units. this set has a keyboard lockout feature.

Press menu for 10 seconds on front panel. if that does not release control then u more than likely have a problem with dm module. there are several bullitens about this and several things a tech can do to repair this set.

I HAVE MITSUBISHI WD-73640 AND ITS SHOW THE GEEN LIGHT BUT DOESN'T HAVE PICTURE OR SOUND


The first thing to replace is the lamp. Google your model number and "lamp" and you'll find several sites that sell them. It isn't difficult to replace yourself and isn't very expensive. Good luck.

Looking what i can do to fix. Have a Mitsubishi TV 3D DLP WD-73640, Replaced bulb, and still have the red LED flashing 6 times to the Yellow led flashing 1.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
Check the lamp ballast too.

Sounds like you need to replace the lamp. An original Mitsubishi lamp will last 7 to 10000 hours. It's a no brainer to replace. Buy the lamp from Mitsubishi or a dealer. Do not buy one over the internet. Those are awful...

You need to replace the 4719-001997 DLP Chip. this should solve the issue.
This chip can be expensive so look around before you purchase. This is a common problem with these TVs, both white lines and white dots.
