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.

Is this a DLP or LCD projector?

It could be a bad lamp but I've run into many of these TVs with bad color wheel assemblies. Also, if you are getting a dialog box coming up with these words," airflow blocked, TV will shutdown ..." that's a defective thermal fuse.
This is a job for a mitsubishi authorized service center. A tech can disassemble the light engine and confirm that the wheel is the problem. If you're still in warranty, great. If you're only recently out of warranty, call mitsubishi for assistance. Remember that persistance pays off when dealing with large corporations. You very seldom get what you're looking for on the first call or from the first person you speak to.
