While watching tv, it will shut off by itself. I have to unplug it wait a few minutes and plug it back in again, then it works again for awhile, then shuts off again. I have no idea why. I have it plugged into a power surge protector. I was gone away on vacation for 2 weeks and it was previously working fine, until I returned home. Now it shuts off by itself. Answered!

@gwilliam could be an issue with failed capacitors on the power board or over heating. Your set shuts off because it goes into protection mode. It will definitely help if you can provide the exact model number. It might also be helpful if you post some images of all of your boards inside your TV with your question. That way we can see what you see. Use this guide Adding images to an existing question for that. Was this answer helpful?

My LG started turning on….then off….then on….and so on. I unplugged everything waited plugged just the tv back in and it kept doing it. So I went and got in front of the tv and it stopped so I figured it was batteries in one of the remotes. I was right the fire stick batteries were dead and that is Amazons stupid idea of telling me to change the batteries in the fire stick remote!!! I was mad thinking my tv was on the fritz contemplating buying a new tv. Problem solved CHECK YOUR BATTERIES. Was this answer helpful? Yes No Voted Undo Score 27 Cancel 43 Comments: Thanks Jeff E…It’s definitely the Firestick batteries. I just pulled mine out and the problem stopped. The Firestick remote was causing the issues. Again, check that first before you do anything else. I cannot tell you why the remote from the Firestick was cutting the TV off because I did not have the synced together but it was. I removed the batteries and viola’!!!! by Darren Neal Same here. It never happened with our old Firestick, but we recently got a new one. Replaced the batteries, tv is now functioning normally! by Nikoa Kmetz-Derr This helped for me too. I removed batteries from the fire stick remote. If it wasn't for disney+ I wouldn't have bought a stupid firestick. I should have known better. Anyway I knew my TV was still good. by Jenn H It worked! Thank you so much!

If you have another device attached to your tv check the batteries on the remote, we had the same issue with a firestick after battery replacement it was fine Was this answer helpful? Yes No Voted Undo Score 3 Cancel Add a comment 0/1024 Cancel Post commentOptions
I just a bought a LG 55" tv real cheap as it had this same problem switching off after 10ish minutes. Took back cover off and noticed the heatsink for the graphics card part was quite hot. Put a fan against it and bingo problem gone. Terrible thermal design in the tv. I cut a hole then glued a little USB silent computer fan to the back cover (I butchered a laptop cooler stand for the fan). When the tv is turned on it powers up the fan, when tv is off, its off. So stoked! Was this answer helpful? Yes No Voted Undo Score 1 Cancel Add a comment 0/1024 Cancel Post commentOptions
I’ve had my LG 55” TV 2 years last night it started powering OFF every 5 seconds when I turned it On. I checked the power cable, disconnected all HDMI inputs (cable box , blu ray player and Echo Cube). This had no effect. I replaced the batteries in each remote control. When I replaced the batteries in the Echo Cube remote it stopped. The batteries in the Eco Cube remote were half dead which was causing the remote to send out power Off commands to the LG TV. The TV has been working fine ever since. I hope this helps. Was this answer helpful?

Double check the fuse in the plug. Mine was a 10amp fuse, but on the plug says it was meant to be a 13amp one. So I changed it and had no problem since. Was this answer helpful? Yes No Voted Undo Score 1 Cancel 1 Comment: I had went through the settings, I remember a update maybe a month ago to the tv when I turned it on, then it seemed to start after that. I went through the settings and sleep timer was off but there was another setting under sleep timer said on but greyed out, so I turned sleep timer on to turn the other setting off then turned sleep timer back off. Then under HDMI there was something I felt not needed so turned it off and so far it stayed off when I took a nap today my son said it was off when he came down to play ps4 on the other tv. I use the 55" for the house security cameras only. I will see how it goes and if it does it again I will look into that fuse, if there is one in my cord by ron35151 Add a comment 0/1024 Cancel Post commentOptions

If you can, try blowing any dust out of it. Even better, open up the back and make sure all dust has been removed. The TV should function fine in room temperatures exceeding 90 degrees. If it doesn't it may be an indication of eminent component failure (capacitors most likely). Dan by Abrsvc @mdavie78 what make and exact model is your TV? by oldturkey03 That’s what my tv does!!

Hi I had the same problem with two LG TV`s , tried everything. I did thing of dumping the TV`s and getting different make. Until I changed media sharing. It`s deferentially a network issue I removed the LG TV from my home network media sharing from PC & Laptop, so I blocked media sharing to LG TV and the TV has been perfect since.

If you have an Amazon fire stick plugged into the tv try putting new batteries in your Amazon remote control. It’s a “feature” to let you know when the batteries are low… terrible feature… Was this answer helpful? Yes No Voted Undo Score 0 Cancel Add a comment 0/1024 Cancel Post commentOptions
I've got an older model but never had the turning off and on problem before. Was prepared for it being time for new TV but did some searching first. Sure enough, one of the batteries had exploded in one of the remotes. Changed the batteries, same problem. Took batteries out of magic eye remote to see if that would make TV work - nothing doing, put batteries back. Tried cooling TV down, dusting the back, checked the fuse in the plug. Nothing. Then decided to change the batteries in the magic eye remote - and that worked! So problem has come with a recent software update but at least I know now. Just change all the batteries!

I just had this start happening and am glad I found this thread. My Nvidia remote (which we haven’t used in a year) needed new batteries and it was close to the tv. As soon as I took them out, the tv stopped turning off and on. Such a bizarre feature! Was this answer helpful? Yes No Voted Undo Score 0 Cancel Add a comment 0/1024 Cancel Post commentOptions
My issue was definitely temperature-related. I eliminated all of the other variables (no Fire Stick, no remotes with low batteries, removed all cables except HDMI which I replaced with a new cable, reset TV to factory settings, tested a variety of video sources) and all it took was moving the TV away from the wall a foot or so so that air could flow behind it. Instant fix. Haven't tried replacing the fuse yet as suggested, mainly because I couldn't find one easily accessible (i.e. not behind the hatch that the power cable goes into.) |
