Unless you do TV repair take to repair shop.I would first look for defective capacitors on boards and like so many others poor solder connection can cause alot of problems.

LG plasma turns off and on by itself while making clicking sounds


Probably the power supply is failing. The clicking sound means the power supply is trying to turn on but can't.

LG TV KEEPS TURNING OFF


Kindly do not keep attempting to turn it on, as you are likely to spoil some other boards/parts/components of the TV. Look for any loose contacts in power out let, RC jack, cable and socket. In order to ensure, it is not caused by the input device, connect a DVD player
and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

How do i reset the projection lamp timer?


Hello
Press the "Power" button on the TV remote to turn the TV on. Press the "Display" key. Press "5," followed by the "Vol+" key, followed by the "Power" button. Wait for the service menu screen to appear on the screen. This could take anywhere from a couple of seconds up to a minute or two.
Press the "Jump" key three times in rapid succession. Press "2" nine times in rapid succession

Press "3" once, followed by the "Mute" key, followed by the "Enter" key. Wait as the screen flashes momentarily.

Press the "Power" button on the TV to exit the "Service menu" and turn the TV off.

The tv immediately turns itself off after i try turning it on. it doesnt matter if i use the remote or turn the tv on manually. It just makes the noise as if its turning on and then immediately switches...


Hi, The TV is shutting down because there is an internal fault, there is more likely a panel that needs replacing or a few faulty components.

It's more than likely repairable.

If it's under warranty contact your dealer for repair or replacement.

Tv shuts off immediately after turning on


Does it shut off shut off, or is there audio present after the lamps shut off? When you shine a light to the screen do you still see picture kind of?

If still see picture, it's inverter/power supply or CCFL bulbs itself. If no picture, completely off, it's DEFINITELY the inverter/power supply.
