Why TV turns off by itself?

by Tienguyen06 / July 12, 2012 3:34 PM PDT

I have a 2 years old LG TV (model: 32LH30). A couple of weeks ago, it turned it off by itself even I did not do anything. After that I tried to turn it on by remote, then it was on. Then this problem happened many times and I tried to reset it by unplug or turn the power off, sometime TV was on. Today, I couldn't turned it on by those ways. My TV has the power because I saw the red light on on the bottom. I mean it is no problem with the power. Then I called the LG customer care, they asked me to do some way that I have tried before, but I still did not work. I have researched on the Internet and I found many people got the problem like me. Can someone tell me what I can do now? May I have a warranty with this case because this TV was defeated. Most TV is used at least 5 years, but this one I used only two years. I don't want to pay any money for this because it is not fair. Why some people use long time, why some not. We also pay the same money for the product. Thank you so much.

What do you mean by "defeated"?

If there is a warranty issue, you call it in and ask.

But what is not fair here? You entered into a contract of say 1 year warranty and did they not honor that?

I know many think these should last a long time but from what I'm seeing, many TVs are failing in the 2 to 5 year span. It's not just my opinion that quality has been sacrificed on the alter of low cost.

i had the same problem-

I got a notice the system was shutting down. It happens when you dont use the remote for a period of time. There is a sleep setting. Go to your settings on the TV and search for the sleep setting. It has some options or you can disable it altogether. It solved the problem

I have solved the LG turn off/on problem

It took a long time and I had LG certified techs come here who charged lots of $ but knew nothing. I think it is a heat problem. When you have the TV plugged in, even when the unit is "powered off" it is still drawing power (this is just a theory). Here is what I did to fix it: 1) remove all the extra connections on the back of the TV other than the ones you are using (I have a cable box and a Chromecast). 2) plug the power for the TV into a power strip. 3) when not watching power off the TV from the power strip. This will allow whatever is heating up and not working correctly to cool down.

BTW, the TV is not actually turning off and on. It goes into a confused state where the screen is dark and the sound is off and it is not able to be turned off or on. Only when the component that is causing the issue cools down, will it "turn back on". Muting or even pressing the "input" key on the remote caused the TV to go into this state. Sometimes it would happen all by itself. But by keeping the TV cool between watching sessions, the problem is solved.
