Try unplugging the unit and hold the volume up and channel down buttons down and plug the unit in. Let go of the buttons and the unit should come on up the service mode. There will be a small k on the screen. With the remote press the channel up button . 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. Use channel down to highlight that line and the 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. 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 .

Hi leprecoce,
One transistor out of millions has failed shorted. That is an unusual failure mode, but not unheard of. The chip can probably be replaced, you might want to check google maps or for a repair shop near you.
Most shops should be able to give you an estimate, I would guess around $300, unless the chip is hard to get.

Unplug the power and leave it unplugged for a few minutes.
Then press and hold the buttons on the TV while another person plugs it in. Hold the buttons down for 30 seconds, or until the set beeps.

It is possible that the flash update was not successful for some reason, in which case the set may have to be returned to the factory, or a factory service center to be reflashed properly.

Please post here to let me know if this helped.

Record model number and google sharp software upgrades. You may not even need to load it , but it always solves my problems as you describe as yours. Good Luck

Factory Default Reset:

- Unplug the TV and count to 10 slowly.
- Hold down the power button on the TV (not the remote.)
- Plug in the TV while holding power button.
- Count to 10 and release the power button.
- Turn it on and hope for the best.

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

You can buy the parts online and fix if yourself!!

switch TVs and see what happens. If the problem now occurs on the old TV, it is the TV. If the problem occurs on the new TV, it is the location. But use a ground fault tester in case that socket has some kind of ground fault

In most of the case, the problem is the LCD panel, we have seen this before.
