My Samsung UE40F6340, which I only use occasionally, has recently started turning itself off. It can take a few seconds to a few minutes before it happens. I've checked the auto sleep settings and similar options and found that none of them are enabled. I also unplugged all connected devices, but that didn't change anything. Of course, I also tried a different power outlet, which didn't help either.
After that, I opened the TV to see if there was any apparent defect, but found nothing. Pictures are attached. Then I disconnected the cable between the power board (right side) and the receiver board (left side). When I did that, the TV didn't turn off. So I assume that the receiver board is sending the shutdown signal.
Do you have any ideas what could be causing this?
