Why does my Vizio TV keep turning off and then back on?

Hi everyone, I have a bit of a tricky issue with my TV. You see, it keeps turning itself off, and then immediately turning itself back on . Here's what I've determined so far:

  • There is no consistent pattern of when the TV restarts
  • The TV itself is restarting, it's not just the backlight losing power
  • It's not being caused ARC or HDMI-CEC
  • It still happens even when there is no input signal
  • It's not being caused by any sort of IR interference (I put my Flipper's IR receiver up next to the TV's, and didn't get any signals)
  • It still happens when I switch which outlet of the surge protector the TV is plugged into
  • It still happens when I switch which outlet the surge protector itself is plugged into
  • It still happens even when I plug it directly into the wall (I tried multiple different outlets, in multiple rooms)
  • It still happens when I switch the TV power cable
  • Nothing else loses power (not even the other devices plugged into the same duplex outlet, nor the same surge protector)
  • When watching something, when the TV restarts, once powered back on, the video has paused itself
  • There is no sign of any burnt traces, broken wires, or any internal or external damage within the TV
  • It still happens when I remove the batteries from the remote
  • It's not an automatic function (there is an automatic power off function on the TV, but I already turned that off)
  • It always turns back on quickly, within 5-10 seconds
  • It doesn't seem to be happening due to overheating

I'm currently at a loss here. Does anyone have any ideas of what could be going wrong?

@shingle Can you take the back off the TV and upload pictures of the circuit boards? Adding images to an existing question

@shingle what model is your Vizio? Explain this "When watching something, when the TV restarts, once powered back on, the video has paused itself" a bit more. Does this go for live TV as well?

Well, I actually don't have cable, so I'm not sure, but think of it like how when you unplug a pair of headphones from a computer, the audio (and/or video) pauses.

@shingle so you are streaming to it.....? do you have a game console, DVD/BR player you could connect to it and see if that changes anything?

Yeah, I have a Fire TV stick and a Blu-ray player plugged in, and it still restarts itself on both of them. I even tried switching which inputs the devices were plugged into, but that didn't work either.
