I've been hearing alot about the main power supply board with this model. Mostly I hear that when the power button is pressed, the relay inside will click but with no other response from the TV. This tells me that either the relay contacts are no good or that there are some serious soldering problems on the board. That would explain why it will operate for a short time then quit unexpectedly. Thermal cycling might be stressing the already weak solder joints causing intermittent contact. Personally, I'd love to get my hands on one of these boards.

If it were me and I had nothing to lose, I'd pull the main PS board and touch up the relay section by resoldering (as I believe it is more likely to have bad solder joints then the bad relay contacts). If anyone tries this with positive results, please let me know and rate accordingly.

Blinking green timer light on front nearpower button keeps blinking, tv will not turn on, unplugged for 24 hours and tried again, also hit system reset and still nothing.

Thats a common problem when the caps on the DM need replacement. They will function fine untill power is interupted then the set will not complete the boot sequence when power is reapplied and the led will just continue to blink. Hers a link to the kit that will usually repair that issue the kit comes with instructions.

Tv wont turn on

take your tv to technician who can check your power supply, if your power is coming on and off, than a problem is not as big. firstly let him check a ht of a supply constantly, your supply is cutting.
