From a cold start up,,, TV works fine,,, then shortly after, the menu pops up. The longer the TV is powered the more frequently the menu pops up. It responds to changes in the menu with the remote, & can be closed (briefly) with the remote. But then pops open again,,,, I tried powering off the TV (wall plug pulled) overnight. No change. I pulled the batteries out of the remote, no change.
