Beosound 9000 Operation Panel not working

[Origami]

Hello all,
I’ve got a Beosound 9000 recently, and the Operation Panel doesn’t seem to work.

When I load the CDs, and press on the 6 side buttons, they work. On/Off and Open/Close glass buttons also work.

The Beosound 9000 is currently not plugged to any speakers, but I plugged an headset into the 3.5mm jack, and the music is there.

But the Operation Panel doesn’t seem to do anything. I pressed all the buttons, and nothing happens. The On/Off button also doesn’t do anything (the one on the Panel).

I checked the backside of the Panel, and it seems clean. No visible rust, or anything.

Any idea what could cause the problem, and how to troubleshoot it ?

Thanks in advance

Hi,

The buttons along the lower edge of the front side are considered the primary keyboard and the set on the “operation panel” are known as the secondary keyboard in the B&O service manual.  Was the unit shipped or transported in order to get to you?  I ask because I once purchased a unit that was shipped in the original packaging but arrived with a dead secondary keyboard.  Everything else worked fine including the remote.  It turned out that the connector plug from the secondary keyboard had become dislodged from the PCB.  Once I plugged it back in, it worked just fine. Unfortunately, it does require some disassembly, but the service manual describes all the steps and it’s relatively straightforward.  Hopefully that’s all that’s wrong with yours too.

Hi Bill,

Thanks for the answer. I bought the Beosound as is.

I’ve seen on Youtube some disassembly videos, and it not what I’d call straighforward, but I can give it a try…

Hi,

I guess the first thing to do is to make sure the keyboard is properly seated in its holder. I would suggest removing it, check for any lint, dirt, etc. and then reinsert carefully making sure it is engaged in the connector first before pushing it down.  This can be a bit tricky. You may want to try both of the possible orientations to be sure it’s a problem in both positions.

If you are absolutely sure that it is fully seated properly and still doesn’t respond, then see the the video here: https://www.youtube.com/watch?v=YR2RgUSTrss

It hows how to remove the top cover, once you get that removed you can see the cables from the secondary keyboard and where they attach to the PCBs. Make sure they are snug.

I’ve removed the top cover for repairs on two of my BS9000s, one for a loose keyboard cable and once to clean the gear drive. In both cases it was not too difficult if you have a video or the service manual.  I recommend upgrading your membership to get access to the service manual, it’s well worth it.
