D32f-G4 Randomly cycles through inputs then goes to initial setup

Got a weird one for you guys... TV is a couple years old at this point. We've cut the cord and have gone to Roku on all TVs (this one recently from stick to stream bar). About 2 weeks ago it decided to randomly cycle through the inputs even going into the initial TV setup (select language, etc). I have tried power cycling, full system reset, Roku disconnected, Roku on another HDMI port, Using a Roku stick, removing batteries from remotes (Roku and Vizio and as far as removing from ALL remotes in the house), even unplugging for prolonged periods with no luck. The TV will do what you want for 10 minutes or less before it starts switching inputs again.
