TV displays green blinking light but won't power up

This is sometimes called the "blinking green light of death" and usually means the DM unit in the set needs repair.

The only other simple thing may be the reset switch on the front of the set has gone bad; The only way to see is to get at and unplug the front keyboard on the set.

I can tell you how to do that if you want to know.

Takes about 5 minutes and if set still does not come on then the DM unit is bad.

Don't freak out. My DM went bad and I replaced a resistor on it for 15 cents. However, if you take it to a TV Shop, they want 800 bucks to replace it.
