Check the power supply for bad caps with leaking/bulging tops first, the power supply may have gone into shutdown mode if it senses shorted circuits such as shorts in the backlight inverter board. Before buying the power supply, you need to checkt the inverter circuits first.

Turn power on, approx. 30 sec later it the power


It varies as to what is actually making the TV shut down. Shorting the connectors on the A.C. plug have nothing to do with it turning back on. Its just the fact you are unpugging it for a few moments.

I power on tv and it shuts down after few seconds


There is a high voltage leak here, the reason it closes down is the protection mechanism isw trying to prevent more damage. better to turn it off and have it repaired before it catches fire or blows all the boards and becomes totally useless or beyond repair.

Sorry this isnt what you wanted hear but there is a safeyty factor involved here.

TV turns on, then turns itself off about 2 seconds later.


set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.

Tv comes on just the sound about three seconds later tv shuts off


I have the same issue with mine and have a solution that sometimes works. I had a repair guy come to check it out and he powered off the TV so that the red light was no longer blinking, then he unplugged the TV for about 30 seconds or so and then plugged it back in. He then turned on the TV and it worked. He said it would cost about $400 to fix the issue (some circuit or something). I have since expeerienced the on/off problem (due to power outage) and now I cannot get the TV to work. But at least give this solution a try and please post to let me know if it worked or not. Good luck!
