Chosen Solution
Can anyone help please? My 55in LG TV switches itself off then comes straight back on again. Not sure what could be causing this??
@chuffer first rule out the remote. Remove the battery and see if it still does that. then rule out your inputs. Remove all of them (especially if you have some sort of cable box) and only connect one input source. See if that changes anything. Unplug your set and unplug all input sources. Hold down the power button for 30-60 sec. Then reconnect the TV and one input source. See if that changes anything. If none of this made a difference, you will have to check the boards. For that remove the back of your TV. Post some images of your boards with your question so that we can see what you see. Use this guide Adding images to an existing question for that. It is possible that this is an IR board error or a failed IC on either the main or the power board.
If you’ve a Firestick connected, change the batteries in it. I did not believe that it could cycling but it does. Problem solved easily. Had to cancel service call as I’d exhausted all other solutions.
I’ve had 3 new lg Oled tvs over the past few weeks. And everyone of them keeps turning off and then clicking back on again 5seconds later, I’ve checked everything my end and everything seems to b ok, but it’s on every Oled tv that I’ve bought I keep taking it back as this is happening all the time,I’ve knocked timers etc off but still doing it
I had the same problem. I had a dish connected with no aerial connected. I disconnected the satellite dish and connected an aerial approximately one month ago and the fault has not come back.maybe just a coincidence.
