Why is my 55 inch LG TV turning off by itself?

Why is my 55 inch LG TV turning off by itself?

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.

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

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!

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.

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.
