SOURCE: My LG Plasma tv 50pb4d constantly turn itself off.

yes it is, and yes it can. BUT it maybe a difficult problem to determine if it is intermittent, you will be best served waiting until it fails "Hard On" otherwise it may take some time to find the intermittent fault. http://www.retrevo.com/support/LG-50PB4D-TVs-manual/id/3068bh134/t/2/

SOURCE: My LG 42PQ10-UB has no picture or sound. When i

2 flashes signals that the power source goes in protected mode. This is what happens: a part on another board inside the tv has failed, when the tv starts the first board that gets activated is the power source one, it starts normally; when the source is fully on the status light goes to blue and the source starts powering the other boards of the tv; in that moment the failed part also starts to receive power and because it has failed it no longer delivers the correct signals to the rest of the boards; when that happens the safety system in the processor detects the fault , signals it thru the status light and stops the powering up process - the power source is sent in protected mode so the status light changes to red.
To fix that properly the tv must be opened and the power source tested to find out what caused the failure and what other boards are also damaged.
This is a very complicated job, you will have to call the repair shop of the nearest dealer and arrange for a visit. In the mean time unplug the tv from the mains.

check your cable coming in from your provider, it may be loose. if that' s ok then rebout your provider box. if that doesn' t work, check the settings on your tv with the remote that came with your tv.

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.

No red led power light. no power at all


Try unplugging it and then replugging it into the outlet. Try moving it to another outlet to make sure the power is good. Try a new power cable. If all else fails, contact LG's warranty service if the TV still is covered.

Lg plasma mt 42pz10


I wish I had an answer for you but I'm in the same boat. I've got a 42pc5d and it's doing the same thing. I'll turn it on using either the remote or the power button on the unit itself. The LED will blink either two or three times, then shut itself off. I tried plugging the unit into a different outlet. I tried unhooking all inputs (PS3, DVD player, antenna, etc). The tv was still shutting itself off. I called tech support and the lady who answered asked me if there was a power button on the unit. Well, of course I understand LG has hundreds of models but I felt like I was dealing with someone who didn't care enough to even open the manual to see for herself. Anyway, after a "reset", the TV is now nothing more than a very expensive paperweight. To say I'm displeased is an understatement.
