RCA TV menu screen pops up.

I have an RCA Model F32648 TV that has recently developed an odd problem. The menu screen for the TV will pop up at frequent intervals, sometimes the Program Guide screen will pop up. Sometimes it will flicker through the screens.
The problem is NOT with the remote. I have removed the batteries, I have even removed the remote from the house and the problem continues.

I bought the TV used from a friend a few years ago and did not get an owners manual. I looked online for tech support for RCA and couldn’t find anything useful.

Any suggestions?
