Turns on then shuts offLG plasma tv model#42pc3dvda

What do you mean by clicks? Plasma televisions are hot cathode ray, there is thermal expansion that takes place due to heat.

Hello
I thinks you may be right. All plasma and LCD panel tVs will have cooling fans at the top side. Plasma screens will heat up much more, and if cooling fans stops work, of has damaged, the set will overheat, and awill automatically shut down; because there is a overheat sensor fitted inside it, will sense the heat, and if the set overheats, it will send a signal to the main system control fo the TV; which in turn shut down the whole system. look fans for proper working. If not replace them. OK.

turn tv on the red power light comes on then goes off again

I don't know but I'm having a similar problem. I have a plasma
TH-50PZ77U. It will run for a while and then shuts off. Also, the volume goes up and up and then it shuts off at times. Like I have a ghost here. I had both of my sat. recievers replaced. It seems to get worse over time with shut down. I called panasonic and they had no info and denied this was an issue but I beg to differ from my research here online. It's only a few years and we paid lots of $$$. They gave me a # for service 1 hour away!

My Samsung 52" plasma TV will shut off while watching TV. It will do it repeatedly and we have to turn it back on. Is it overheating and shuts down? How can this be fixed?

Pioneer plasma pdp R03U shuts off and tv shows E01 or action freezes while soun dgoes on and then stops E01

U WILL LAUGH, WHERE THE PLUG GOES INTO THE ACTUAL TV, NOT THE WALL, PUSH IT IN BETTER...I HAD EXACT PROBLEM AND CAME FROM 2 1/2 DAYS FROM GETTING NEW PLASMA!!! WHEEEW

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.
