SOURCE: 50" lg plasma tv keeps shutting off

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.

50 inches LG PLASMA TV TURNS OFF AFTER 15 MIN.


A blown capacitor might not be the reason. After 15 to 20 minutes of work, the temperature inside the set do rises much, this kind of fault can occur. Check its cooling fans.

I have a 52" LG 52SX4 DLP TV, it now shuts off itself after about 10-15 minutes of playing. The bulb is fine, and fan is working fine, it doesnt get too hot, but tv still shuts itself off. I can turn...


Look for capacitors that are bulged and going bad, that is a common symptom when they fair, either the set won't come on unless its warmed up or it will shut down after it run for awhile

Tv turns off after 15 minutes of use


For bobby11 and luis, it is the power supply. Part Number EAY34797001 in the 42" and EAY34796801 in the 32". This is a known problem, and somebody should start a Class Action against LG over this one. Part is available online and easy to swap out for anyone with the most basic knowledge.

Shutting off and on...


the problem may be due to dry soldering in the power supply stage if it was with the lamp there would be red or green light showing the presence of the power to the tv after making it own some of the components get hot and it will make the the soldering point conectionless and after some time the heat sink get cooled and the soldering point gets connected and u will see the picture again it is a simple problem if u have a soldering iron u make it hot and re solder all the components in the first part of the circuit board and the problem if rectified
