My 65UQ70 TV started to ignore my remote yesterday. After some experiments I've found that it only reacts to double clicks now. So I have to use double clicks for any action - move through menus, launch apps etc, single clicks are just ignored. Resetting the TV to factory settings didn't help. I tried to google the issue and found that this might be an issue with the remote, but I can't find how to reset the remote of my model. Combinations like Home+Back (for Magic Remote) or 2+8 (for some old style remotes) don't work for my model, neither removing batteries and pressing all buttons does. My remote seems to be AKB76040302, a photo from the Internet is below. So, how do I reset it? Some other things to mention: - The pulses of the remote are not visible through a cell phone camera, so I couldn't check if it only sends signals to the TV after double clicks, or the TV is enforcing this issue. UPDATE: a cellphone sees the pulses in darkness, and a pulse is sent on each press, not only on doubles. So it should be TV OS issue, not the remote issue. - This started to happen after I have updated the software and connected a sound bar with optical cable, though I believe the last action isn't related to the issue.
