The green LOCK light is on. There is NO re-set button on the bottom or back of the device. I have tried switching it off and unplugging it for over 1 minute.
SOURCE: won't power up
This model has had problems with the keyboard buttons on the front panel,causing them not to work and canceling out the remote operation. To verify this,you need to remove the front panel so you can access the connector on the keyboard pc board and unplug the connector.After doing this,see if the remote control is able to turn on the tv (wait for it to power up because with the connector off, the green power light will be disconnected and will not light up when the tv is on) If the tv works, than you will need to change the ten individual switches on the board - part# 432P089010 (or just use the remote only)

on the signal board replace the caps by the 5/9 volt regulators. c2p04 is the main culprit. 6 caps in total can be changed. I believe c2p05 also.

You need the WS55909 - WS73909 DM kit. You can get it at the following link which contains the capacitors and the CD with instructions on how to do the repair.
