TV automatically turns off. unpluged the tv and

Sometimes channels are taken off air and replaced with another channel, and there's nothing you can do about that, but first try this = Turn off your TV ,and unplug TV ,and any other units you may have conected to it, Also remove ARIEL, leave everything off for around 15 mins , without conecting anything to your tv ,plug it in,turn it on , and start to run a first install of channels, nothing will be found !. now unplug TV again ,leave off for 15 mins ,then plug in everything as it was before we started, and run a first channel install, hope this works for you. good luck.

Hello, Unplug the tv from the wall and let set for 30 mins and then plug back in and try. If doesn't work you will have to take to repair shop or get a new one

Assuming it is not hardware but soft settings...
1) Check and make sure that your TV does not have the timer set.
The Timer feature allows you to set a day and time for the TV to turn on automatically and the device and channel to display when it switches on. If the TV is already on at the requested time, the TV automatically tunes to the channel you designated in the Timer menu.
When the Timer turns on the TV, the following message is displayed: "Press a button for the TV to stay on." Press any button on the remote control within five minutes if you wish the TV to remain on.
Note: The TV clock must be set before you can use the
Timer feature (see preceding page to set the clock).
On/Off
Press down arrow / up arrow to enable or disable the Timer.
2) If not working, try SYSTEM RESET. Press SYSTEM RESET button on the front panel with pointed object (e.g. straight paperclip). TV turns off, green LED flashes for about 1 minute. When it stops flashing turn the TV on again. All settings other than Parental Lock need to be set again using the manual.
3) TV RESET. If all else fails for soft error. Your manual describes this last resort for soft type error. It could be hardware problem needing more expertise.

Likely to be main board issue which is the most expensive board in set and also not likely to be a do it yourself repair.

these particular tvs are very sensitive to voltage changes spikes etc.first turn off main power switch wait at least 30 sec if standby come on wait another 30 then turn off main power again and unplug tv for 1 min then plug in turn on main switch wait 30 sec then turn on tv with remote resets system.then buy a ups and always wait at least 30 min after turning tv off to turn back on if not causes power failure and after each press of power button wait 30 seconds before trying again lmk good luck

the software in the main control is damaged. call your lg servicer in your area. he might get you a software update

Please unplug the tv for 30 min and then plug it back to power supply and see if the lights are blinking again...




Good luck......

The tv may be in stand by mode please unplug the tv and wait for 30 min and then plug it back , if the problem exits try it different power outlet.............

check for sleep mode and whether the timer for sleep mode is on or not, if sleep mode is on lets say 30 min or 5 min , ur TV will turn off automatically after that much time
