The MOL had a power outage ~ 1hour. When the power resumed, her video
was playing stone dead. The rectified DC in the PSU is alive (all the
time) but the soft-on front panel power button does zip.
 
Have you checked all the C's with chemicals in them with a ESR meter on the
PCB PSU it is possible that they dropped a bogie.

Yeah, common, Replace all the Electros in the PSU.
Hopefully it has not taken out the Display, or Loading motor Ics..
These units are a Piece of CRAP!!!

There is a list of things that go bad.
Few parts in PS, few on main board. And this is if you are lucky! If you are
not so lucky, capstan motor and display may be dead as well.

I can e-mail you instructions when I get home tonight.
That would be great.
