Your Television uses a sensing circuit that is basically part of a mini-computer. Sometimes either the sensing unit can be bad itself or there is a power distribution issue.

Test - Make sure you try another input source like DVD or something other than what you are trying now. If it plays and does not shut off, the TV might be ok, it might be something to do with your other source you were using when it went out, like your cable box etc.
(most LG's have input sensing and if there is nothing coming in the TV it will shut down or go into standby)

If you have run this test my friend, you may have no choice but to take it in or have a service call. A LG specialist might bring the board you need in to repair it but that can be rare. Most of the service guys that come out are following instructions in a systematic troubleshooting guide and do not really know how to troubleshoot per say, they are card replacers until it works.

They cannot fix the problem in the home if you cannot repeat the problem in front of them and it is consistent.
You may want to call LG or Write their tech dept (good luck, they kind of are not that customer service oriented that I have seen).

I always recommend the extended warranty on a high-ticket item next time.

Hope that hepls and let me know how it goes.

I have a 50" LG plasma that turns off after a couple of minutes.


check the solder side of the pc board. If there are any connections that look grey (as opposed to shiny) you need to re-solder them.

The ambient temperature might be high. Check whether the foolinf fans are working or not. If not, check out the reason for it. The TV must be placed at least 6cm away from wall, and should have sufficant ventilaation.

4 year old 50PC1DRA LG Plasma tv. TV would come on after several tries, now will not turn on at all. Just clicks. From what I read here, could be power supple? Is a 4 year old TV worth putting that...


It's the capacitors on the power supply, it's a common problem, either buy a capacitor repair kit (yes they make them) and have a TV tech solder them on, or buy a new power supply board (about $200) and remove and replace it yourself (it's that easy)

I have a lg plasma,and the problem is it comes on for about 1 second then shuts off. repair shop says its the power supply? what do you think?


If the repair shop says it is powerboard it means they already took a look at the TV and you dont need to worry about it.
If you have any doubt please post the sympton here (detailed) and I can tell you for sure what the TV needs.
I need to know what the led does and how it does.

TV keeps shutting off automatically


Since your plasma is less then a year old, I would suggest to contact the manufacturers to get it fix under warranty. If the plasma keeps shutting off by itself, that is not normal and should be repair.
