So I have got a replacement part on order and the whole thing back together and fully (well almost) working again!

 

I have 2 problems at the moment. 

 

The screws which are removed along the back (heat dissipation grille) to put the 9500 in the service position were practically ground down when I came to remove them (looks like someone had a go previously). All of this set are of no use. I tried screwfix and Maplins but both can't match the size. Does anyone have any ideas of where I can get some of the same size?

 

Second problem is the passive speaker out terminals don't work or only cut-in in a very broken manner. Connecting to the MCL they work fine but mute then doesn't work on them (Beovox cx50's). Other than trying to clean inside the terminal connections, has anyone experienced this problem before?

 

Thanks for any help

Sounds like you are having problem with mute relay. I just few days back replaced same relay in my BC9500. You can try to "clean" the mute relay or just replace it. Some say that cleaning is not a long term solution though. You can try to push mute button several times and see if sound quality gets any better.

The screws are M3 * 10mm Torx black set screws

Yes; the local muting function of the Beocenter won't affect the second speaker outputs. Otherwise you couldn't mute the local & link rooms independently from each other. The MCL boxes have their own muting relay.

As Graham said the screws have originally a Torx T10 head. Some knothead has probably destroyed them with a Phillips driver because he was too cheap to invest 3€ in a proper tool. You can replace them with regular Phillips screws if you want.

Thanks for the post funny as I was reading it before but didn't put 2 & 2 together that it may be the same issue.

And dont buy some cheap sh1t, buy good quality tools, they last for years and has the right dimensions.

Thanks all for the prompt response, my thoughts exactly on the philips screwdriver, there was so little left of the head I had to cut in a slot to use a flathead to undo them.  I can at least source some on the internet now with the information you have given me.

I will have a good look through the other post and get to work on the mute relay.

 

Thanks again.

I scrapped a Panasonic Flat screen, I opened it and took out all the screws I could easily get at, a lot of M3 and M4 Philips head, and a lot of washers.

Yes , as the mute relay only works on the Spk1 sockets.

The funny thing is that they usually have slotting for a flathead if one bothers to look before mauling them with a Phillips Smile

Not in all cases, though. If you intend to work more on B&O kit from those days and later, get a selection of three Torx drivers: T10, T15 and T20. They'll be enough for most, if not all needs.

I greatly prefer Torx over Phillips for every use.

Yes I thought they did but these didn't. There was basically just a smooth bare metal recess where the grip used to be! God knows who decided to have a peek inside previously and what they did.
