Mitsubishi WD73838 DLP TV formatter board replacement instructions

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.

Your access should be a a panel near the back or side. You will see that it is somewhat easily removed and should have maybe one or two screws. You will see the casing to the lamp. Go ahead and remove it. Now unscrew the old bulb and replace it with a new one. There is not a lot of screws holding it together. It's a fairly easy process once you find the lamp. You should see the lamp once the panel is removed.
