Turn off the set and unplug it from the wall and any accessories you have plugged into it. Then hold in the power button for at least sixty seconds. When you replug it may works again having been reset. Worth a try before you spend $.

TV won't turn on power light flashes 10 times


Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

The TV will not turn on. When the switch at the lower left corner is pressed the light in the switch flashs green for about 4 seconds as the TV seems to go through a start up procedure. Then the light...


The red flashing light is the service code. My guess is the power supply is bad now, but it could be something else. If the TV is under warranty, take it in and get if fixed. If it is not, then you may try to check the power supply first. Count the flashes of the red light and check online for the issues when this model flashes, 4 times or 6 times... or 9 times, etc.

Good luck!

Hello have a problem with tv Model is: lg


http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=6281

The above link goes to lg's website describing the red flashing light where the power switch is, and

another switch down below which can turn that light off.

Try switching that other switch below off so the light turns off. Then, switch it back on.

If that doesn't work, then service should be scheduled for this discontinued model.

Hope this helps on your lg tv.

The tv will turn on but no the screen wont. and


Replace the lamp would be the first thing to try. Lamp door switch on this model is notorious for going bad. If you replace lamp and still won't turn on jumper door switch. If you take off back you can see switch board.

Tv switching off


This particular unit has a built-in diagnostic. The LED in front will blink for a set number of times following the failure. The blink code is:

1 Flash Power+140
2 Flashes Low B+ D.C
4 Flashes Hi Voltage Hhs
5 Flashes Ic4511
6 Flashes Ic4518
8 Flashes Audio Amp

Can you possible tell how many flashes there are following the instant shutdown?
