sounds like it has a bad DM assy, or a bad 9v reg ic.
the dm can be repaired, there are 4 capacitors on it that need to be replaced.

generally this means a bad digital module.. as a techinican the first thing that we would check are what is know as standby voltages. if they were there we would replace digital module.! question. Does it blink for more than 70 seconds. This unit comes with a lockout feature. to unlock press and hold menu down for 10 seconds on front panel.

This Chassis has been known for a slew of Capacitors failing throughout many of the Circuit Boards. The best way in my opinion to fix the set is to send the Chassis Assy to Mitsubishi for them to rebuild it. Some folks have has some success in replacing the bad Capacitors in the Power Supply, the DM Board, and the Format Board to get the set to turn on. These Capacitors are identifiable because the tops of them are bulging up.
It is a difficult set to work on and disassemble, this is Mitsubishi's Customer Service Number in case you need assistance. 1800-332-2119
I hope this helps,
