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

SOURCE: cannot turn tv on

Check power supplly make sure its not the fault in wht this will not turn on.

Unplug tv from wall wait 30 secounds and plug back in.

If that does not work you will need to have someone look at the powersupply.

SOURCE: Screen is dim. Have brightness turned up to max

Yes... from the moment the lamp is put into service, it begins to deminish in brightness. You should order a replacement lamp to have on hand.

How can you diagnose a failed lamp in a Mitsubishi DLP WD 52631


Remove the lamp and do a visual inspection.
If this is a DLP you may have a bad color wheel! whistling sound is a sign of color wheel.

Good luck to you

How do you do a convergence on the wd73286?


Hi,
Mitsubishi WD-73286 is DLP tv that does not have any convergence circuit inside.
Convergence is required in old model rear projection tv that has three basic colors picture tubes to generate color picture that projected on front screen of tv.
DLP tv has light engine to generate picture, it is similar to multimedia projector that throws its picture on wall.
Hope this info will help.
Thanks.
