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.

You most likely have some faulty capacitors on the power module. You can easily identify a bust capacitor. They will have swollen tops. Here is a sample pic:

Check the specifications of the faulty capacitors, and getthe replacements from your local electronics shop. If you are comfortable withthis, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out thedefunct capacitors. Once that is done, solder in the new capacitors carefully. Ifare unsure how to do this, try to get a friend who knows this kinda stuff to doit for you, or get a qualified technician.
Warning: If you do not have a background inelectronics repair, or are inexperienced, get a qualified technician to do itfor you.

REMEMBER there are very dangerous voltages inside a TVthat can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECTTHE POWER BEFORE YOU DO ANYTHING.

If you want to go in for a long term solution, youcan easily replace the whole power board. You can get spare from HERE.

When tv goes out, press the menu and input buttons. The green light will flash with a 2 digit code.

SOURCE: Mitsubishi wd52525 shows error code 37

error code 37 is either the dmd fan or the lamp fan. you can see the dmd fan with the cover off. you cannot set the lamp fan as it is under the light engine. I guess the easiest thing to do is get a lamp fan 299P282010 and a dmd fan 299P283010 and change them both.
