Mitsubishi 738 series dlp tv picture doesn't show until tv is reset

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.

It sounds like you need to buy a new bulb, this is what usually happens when the bulb is burning out this bulbs are made to last 6000-8000 life hours

One of two possible issues:

1. Lamp is nearing end of life and may dim just before total failure.

2. A few of these models have 2 mirrors(check with Mitsubishi to see if yours is one) A large mirror in back (never gives a problem and do not try to clean it. Some idiot in these sets used a small mirror inside that the optical unit shines the picture into (wedge shaped mirror and small) and it is facing up----the fans intake air from the front of the set around this mirror--it gets coated with lots of dust---Picture can loose up to 70% of its brightness and clarity if that mirror is dirty--looks like 20 year old set .

If you do not wish to check with Mitsubishi GOOGLE THE MODEL NUMBER with "mirrors" to see.

If it has 2 mirrors I can tell you exactly how to get at it.
