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 is common for a cuircit board called the dm(digital module) to go bad in these units. this set has a keyboard lockout feature.
Press menu for 10 seconds on front panel. if that does not release control then u more than likely have a problem with dm module. there are several bullitens about this and several things a tech can do to repair this set.
just a head's up, getting this repaied my cost a little big.

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.
