Listen carefully, if you turn on and it goes off after 2 seconds, you need to change f902 and check q05a00 for short, if shorted, replace it, and then check for 130v and 34 v on transformer, if they are present, your problem has been solved, if you turn on the tv and hears little clicks, replace the optocoupler of the power supply. i did it and got my tv back on again!!!!

Check for opens at convergence ic's, if none replace stk391-020e's with new lead free sanyo drivers or just trouble shoot them.

When I press power, light blinks for about 15-20 minutes, then goes off. Press power again, on solid for 30 seconds, then goes off. Press power again, TV finally comes on.

Your television is in need of repair. Hard to tell what exactly needs to be repaired but when the power light blinks in that way then this is the TV's way to tell you it needs to be serviced.
