The TCON board or the LCD panel is faulty. Can confirm by replacing the TCON board.

If only the picture is out, and audio is normal, the fault is with its back-light inverter board. If both picture and sound is absent, and the standby light is ON, the fault is with its main board. If set is fully dead; even there is no standby light at all; the fault is with its main power regulator [SMPS] board. If you wish to get some details; check the site linked here. Pull up older posts.

Sounds same as my problem. It is the AC adapter, if your model has this, that is that box on the power cord line. I tried an adapter from my Samsung TV on it and it works, but can not find anywhere to purchase one. I have posted it so watch for reply. I tried Radio Shack Future shop, and called electronic shops to no avail.
Watching a movie tonight...and slowly there was odd behavior from the screen. No volume at first, then flickering, fragmenting and now, as the others only shows the red power. I have noticed some strange flickering the past 2 weeks or so. I thought it may be the cable, so did not concern myself too much. I believed that was the problem tonight as well. But the screen is definately not responding to the remote or manual button.
