Power I recently moved my tv upstairs and in the process something happened. Now when I turn the tv on, the green power light at the face of the tv turns on, there is a click like the tv is coming on and then everything shuts down within 3 seconds. Any ideas?

Are you sure the wall socket is ok , have you tried another outlet .

i found something on internet for your problem.

If the TV does not stay on, press the POWER button on the control panel for at least eight seconds to perform System Reset. The TV will turn off. Power on the TV and the green LED will flash quickly for about one minute. The changes you made most recently, before using SYSTEM RESET, may be lost. If this happens frequently, obtain an AC line power conditioner/surge protector.

An unusual digital signal may have been received, triggering a protection circuit. Wait for the light to stop flashing and turn TV on.

Momentary power fluctuation caused the TV to turn off to prevent damage. Wait for the green light to stop flashing and turn the TV on again

check your lamp door interlock switch.

Look at the power supply first, look for burnt parts, bad capacitors, etc.

Please post back what you find.

Power supply is bad,,

You can try to unplug the main motherboard plug, then plug back in,, It should last as long as it stays pluged into the wall.

Keep it pluged in when you do this,,

Is their a speaker or something electronic or electrical near the tv? Move it away, if there is, and see what happens.

Hold down the "input" button and "volume -" button while the MAIN POWER BUTTON IS OFF. Then turn on the main power button while those are held down, the light on the tv & avc box will turn green. When it turns green, immediately let off the 2 buttons and press "volume +" button, then press the "Main Power" button. Next step is to repeat the process about 20-40 times & the TV WILL WORK!. I have read that this may have something to do with the energy star compliant commands that can changed through the serial port.
The above is from psxpirate25. Thanks!
I had to repeat the whole process a couple of times to get rid of the factory setup firmware mode. Do it 40 times, I would mess up the sequence a couple of times. Keep trying, it does work.
