AKAI CFT2791 TV - unrequested intermittent menu appears on s

[nucleus]

while watching tv, an unwanted, unrequested intermittent menu will
appear on the screen. sometimes the menu will remain for one or more
seconds, then disappear without my intervention. often it will not
disappear and i have to press "menu" on the remote to remove it from
the screen.

this is not a problem with the remote. i have removed the batteries
from the remote and the same intermittent problem occurs, as described
above. also, there are no other remotes being used in the area when
this is happening.

i have the schematic for this tv. can someone tell me which component
in the tv is likely causing this problem?

Does the TV have a "menu" button on the front? Does it have a dirty or
damaged contact?
