Maybe a different problem, however there has been a time that my BeoCenter 2300 was going bananas. The doors were opening by themselves, with no reason. Or they would not open if I asked to.
So I cleaned the glass doors to make sure there was no dust inside out. I also realized there was a light reflecting directly on the movement sensors, so I move it a little bit.
Sounds crazy but since then, I never had the problem again.
I hope you solve your problem!
