I have the same problem unfortunately. On mine, the volume goes all the way down, the menu pops up randomly and the remote won't work so I can't control the TV. I took the TV to the "designated" repair shop twice. The first time they said they did a software update, brought it home and it still had the same problem. The second time I took it in they said the same thing, did a software update, but yet again it still messed up. Then I bought a Philips surround sound...
