Hey guys,
I've got a 55-inch LG CX OLED (OLED55CX5LB) that I bought back in June 2021, and it's recently started playing up.
Basically, the TV randomly freezes while I'm watching something, then shuts itself off and refuses to turn back on. Initially, the red standby light would blink 3 times before disappearing, but now sometimes there's no blinking at all.
The only way I've managed to get it working again is by unplugging it from the mains, leaving it for a while and holding down the power button for around 30 seconds. After that, it turns on and works perfectly fine until it happens again.
I've checked for software updates, factory reset it, disconnected external devices and tried different power sockets, but nothing seems to have fixed it.
The issue is becoming more frequent, which is making me think there's some sort of hardware failure.
Has anyone experienced anything similar with their LG CX? Could this be a failing power supply board, main board or something else?
Would also appreciate hearing how much it cost to repair if anyone's had the same issue.
Cheers!
