      I have an lg 60pn6500 that did that. It would do it sometimes 3-4 times a week.
      I changed the mainboard. Hasn't done it since Christmas time.

        Ok thank you much. Looks like some chip overheat on the main board so it make sense!!!

          It's been a few years since this, but I think I've figured out the reason. Reflow and the small heat sink on the HDMI port was the issue for me. I heat gunned the chip for 1 minute at 450C and increased the size of the heat sink by sticking a large aluminum piece on that chip. The issue has not happened since.
