Hello,

Thanks for the suggestions!

There isn’t a plasma TV in the room, and the problem occurs even when the remote is out of the room (I also checked by looking at the IR transmitter LED on the remote with my phone camera). The keypad seems to work fine, and I suspect the lights are just being made to look bright by the photo – I don’t know about them having been replaced, but I only recently got this system and don’t know anything about its maintenance history.

I haven’t tried powering off/disconnecting the speakers, as I realised something else first: it seems to be related to having an external device connected to the aux input of the system. With no device connected, or my laptop connected, the door problem seems to go away. When it is plugged into a desktop PC (either onboard audio or a USB dongle) then the doors go crazy. I guess the BeoSystem must be sensitive to some kind of badly-filtered electrical noise/coupling coming from the desktop.

Not sure what to do about this yet, but at least it’s something to look into further…
