Question about Televison & Video
The most common thing to fail on modern TVs is the power board. I would take the TV apart and check the internal power board and the capacitors on it, if any appear to bulge in anyway try replacing them.

I've got the same problem. No sound, no picture, just a green light. The light comes on when its plugged back in. No buttons work. Occasionally the light flashes off.

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

Had the same issue, I replaced two 1200uf caps on the power supply board and now it works fine again. Remember to replace the caps with caps rated for at least 35wvdc.

Check back light inverter,if ok then check the 12V and 5V line,if not OK probably the IC in the power supply is defect ( F9222 )

I have the same TV and I just replaced the Capacitors. It came with 2 10000UF 10V caps and I put in 2 1000UF 35Volt caps from radio shack. Its like brand new. There is even a video on how to change them on You Tube.
