Denon 2310 changing sources on its own!

Anyone ever have their receiver just change sources on its own?
My Denon has been acting funny and just changing sources in the middle of playing xbox lately.

Not completely on its own. But, my Sony 475 in my office sometimes changes sources when I push the mute button. That's a "mechanical" problem on the circuit board.
