Set turns on then turns off a few seconds later

try changing the power saving settings!

is the alarm set,if not the main power supply inside it is no good

Replace both of your convergence ICs they are STKs big black ICs will have part number on them.

what has happend is that the phone has detected a virus, like if you have ever used the wire that came in the box to connect to your computer to charge or to create mass storage and the computer has an undetected virus that can get into the phone via the wire, so what i recomend you do is that you scan your computer for undetected viruses, and also restore factory settings on your phone turn it of for 30 seconds turn it on and try again, if this does not work contact your service provider or LG themselves and treat the situation from there.

Your TV needs the part 313501707611 - it's the keyboard that's the cause of your problems - but here's the catch... Philips does not make that part anymore... they say that you need to either find someone to fix the keyboard (which I've had no luck on) or buy a new Television from them... hmm, a $2000.00 TV that needs a $20.00 part now becomes a plant holder in my living room because Philips wants us to purchase a new TV from them.

We seem to have had the same problem. Green light keeps blinking but will not turn set on or off. I unplugged the set for a few minutes, plugged back in and works fine but will happen from time to time for no reason.

Hi! ronogre,
This set has a defective SMALL SIGNAL BOARD.

Toprol

HI NEED REPLACE A SSB SMALL BOARD IN LEF SIDE
IS VERY FAST TO REPLASE IS HAS ONE WHITE CABLE PLANE INSERT TO BOARD THE SMALL BOARD IS INSERT TO BIG BOARD IS COST YOU $ 319,88 LESS $ 100 CORE BACK A OLD BOARD

the problem is due to the crystal which sets the speed of the processor and it may be dry due to heat if that crystal is replaced or dry soldered the problem can be solved
