Hi, my TV is 3 years old, and I’m using it only with : HDMI 1 : Computer in 1920x1080 @ 60Mhz HDMI 2 : Nintendo Wii U 2 in 1080p Since a week now, sometimes (it can be every 5 minutes, or 30 minutes), the TV reboot by itself (LG logo, then come back as normal) But, let me helps to find the source of this problem, as something wierd : I’ve the same issue with the WII and the PC (even if I disconnect one of them)On the Wii U, I’ve the issue in 1080p 1080i, but not in 720 resolutionOn the PC, I tried to change a bit the @60Mh, but same problemOn the PC, I’ve this problem on the desktop, but not when my daughter run the Game “The SIMS 4”On the PC, I’ve this problem when I read a video file with VLC media playerOn the PC, I don’t have this problem when I watch TV through Google Chrome (web site with live soccer game) What do you think?
@chamann could be an issue with the mainboard since this seems to happen in the higher resolutions. Check the larger IC‘s on the main board for anything obvious like loose heatsinks etc. the other thing you want to check is your firmware version. Go through your settings and see which version your TV has and then check to see if there is an upgrade available from LG. Update (06/18/2021) sounds like a main board gone bad. Check the IC and post some good pictures of your board with your question. That way we can see what you see. Adding images to an existing question
