BeoCenter 2500 door issue

[Guy]

Welcome to Beoworld!

Random thoughts:

• Plasma TV in room can cause problems with IR.
• Are you sure that a remote isn’t on permanent send?
• Try powering down/disconnecting the speakers to see if they are having any effect.
• The keypad at the front can fail but I am not sure that would affect the doors. Do all the buttons work fine?
• The lights either side of the CD and Cassette mechanism look very bright (but it may just be the camera) – have they been replaced with an aftermarket version or LEDs that may interfere with the door sensors?

Good discovery!

I did vaguely remember a door compatibility problem being mentioned before, but with speakers.  When the BC2500 was used with the BeoLab 3 speakers the doors misbehaved.

I did a search and found it mentioned here: https://archivedforum2.beoworld.org/forums/t/46913.aspx

And also here for BC2300 (the link within the above thread no longer works):  https://archivedforum.beoworld.org/forums/t/32921.aspx

I would have a play around with the location of the input device and try some different cables (and different cable routing).  Hopefully you will find a solution that works for your preferred setup!

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…
