Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.

Try resetting the TV. Here's how to do it - Unplug the TV's power cable. Keep the Channel Down and Volume Up buttons on the TV pressed and plug the power cable back into the outlet. You will hear a click when you plug it back in if the reset is successful. Hopefully this should restore your video and audio.

All,

I had the same issue after one month of use. A repair cie came and fixed the problem. It appenned to a neon connector that wasn't properly plugged in the TV.
The Technician explained to me that m TV had 16 neons and a sort of controler for those. Often - from factory - a cable is not sitting properly in its position...

Since I have no problem.

It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:

1. Grab a flashlight.
   
2. Turn on the TV.
3. Shine the flashlight onto the screen.
4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
5. Replace which ever is the culprit.
