I have a UE55RU7100KXXU TV which has been working fine until today. When I turned it on this evening, it just kept turning on and off repeatedly every 1-2 seconds. It appears that when a button is pressed on the remote, the TV thinks it is being hit repeatedly. So it appeared to think the power button was being pressed continuously.
When I quickly pressed the channel up button for example before it switched off, the TV started going up through the channels as if I was hitting the channel up button. It was the same with any other buttons - TV seems to think the last button hit is still being pressed. I have a second Samsung TV and when I used that remote with this TV, it was the same problem, so it is not the remote.
I haven't seen this problem reported online anywhere. Any ideas on this?
Thanks for the response. Can I just check what you mean by factory reset? Is that going into Settings, General, Reset and entering the 0000? It's not actually that easy to do that given the problem the TV has - it's very hard to navigate through to this screen.
