Weird problem with LG 50 PQ30

[Bobc]

My 4 or 5 year old LG 50PQ30 is displaying a window asking if I'd like to enjoy my new device. If I select "yes", it switches to AV2, and there is nothing plugged in that input. At times it starts flashing this message every couple of minutes, and if you turn it off, it may pop right back up. I've reset the tv, that hasn't helped, and LG says they have not heard of this issue. Anyone have any ideas, or is it time to scrap it?

Have you tried cleaning the socket - check for bent pins. If the set is 4-5 years old
and not been opened may be worth trying spring clean in case dust is conducting.

Try plugging something into the AV2 (after cleaning) see if that stops it.

I moved the input to HDMI3, and it worked for a while, then that input started doing the same thing. I'll try blowing out the inputs and plugging something into AV2, thanks for the answer.
