PindsenBRONZE MemberHi,
Does the moving to the far upper happens every time the CD stops? If so I would assume it is okay since the voltage to the lense moving mechanisme might be shut off every time the CD does not succecfully starts up (recognize the CD). If you are sure about the correct polarity of C2103 then I would try the adjustment as Spassmaker suggest.

PindsenBRONZE MemberHi again,
It turned out that the BC8000 did not have a “TR9” issue – my issue was also a little different. It could Play, REW and stop by command but when selecting FF it stayed in FF eventhough pushing Stop. Measuring around on board 4 showed correct electrical signals. It turned out that the FF solenoide was half stuck staying in outer position. Lubricating the rod inside solved the issue.
Finally everything works 🙂/Pindsen

PindsenBRONZE MemberHi,
I took the board 5 apart and could see that 5TR1 is a BD534 so there are a type mistake in the service manual. 1C53 is not shorted as is was replaced previously and still measure ok. It turned out that it was the flatcable from board 4 (section B4) to board 1 that had bad connection in the board 4 socket. It was very difficult to see, it was only a random pick from my side to lift it up and clean all flatcables and when lifting this flatcable it was clear that it could not have had any connection in the socket. The reason for cleaning the flatacbles are because some of those for board 4 have grease in them from the front lid opening mechanisme. Ensuring that all flatcables have proper connection the tape deck now works again.
Now next fault behaves as this issue:

Maybe I also “just” have a TR9 issue./Pindsen

PindsenBRONZE MemberHi,
Okay thank you, for the second question then yes I mean when it has been unplugged from mains. I was just wondering if a backup battery had been drain, but seems like it is a “feature” 🙂
Regards to the ability to show the time remaining of a track, I had that on my old Sony stereo and for some reason I liked it – it’s a pitty we cannot request new features to be added for the BS9000 – we will just have to live with where B&O ended despite the product remains in use for many years to come./Pindsen

PindsenBRONZE MemberOkay, I thought so but it could be that they had a “factory setting”.

PindsenBRONZE MemberThank you, that makes it clear. It is impressive how much effort he put into his restoration projects 🙂

PindsenBRONZE MemberHi,
Okay thanx. They are not easy to get access to in general.

PindsenBRONZE MemberHi Guy,
Thank you that works better 🙂
I by intuition had an idea that since the SHIFT command is “hidden” in the List menu it needed to be “activated” with a push on the GO button but that is apprently not the case./Pindsen

PindsenBRONZE MemberNever seen it, which film is it?

PindsenBRONZE MemberNice to see new stores, could be intereting to see some pictures from inside.
From your description I am a little in doubt if it one of thoses already on the B&O map?

PindsenBRONZE MemberHi,
No that is not normal. In most cases it is the idle trimmer in the output stage being defect. Try to replace it and trim it in according to the service manual.

PindsenBRONZE MemberHi,
If you are slightly skilled you can do the electronic upgrade via this kit:The foam you can buy several places and they are not difficult to replace.

PindsenBRONZE MemberHi,
Thank you. As far as I can see Beoparts-shop does not have a belt for a BS9000 and I am a little unsure if those sold on Ebay are correct in specification (Maybe Dillen knows)?

PindsenBRONZE MemberHi,
Beomaster 4500 and Beocenter 4600 are different units from different year periods, so you cannot compare.

PindsenBRONZE MemberHi,
The switches was fine but the orange wire to the Pause switch had fallen of (was not easy to see from above). Now it works 🙂
Thanx Martin for leading my attention to the switches./Pindsen
Location: Denmark
PindsenBRONZE MemberBoth the playback switch and the pause switch are okay (open-circuit when not engaged and short-circuit when engaged).
The playback switch are not activated during playback, it is open-circuit. The pause switch is opposite.Location: Denmark
PindsenBRONZE MemberHi,
I agree with Matador and Hugosnel, a repair is not difficult – I have done a few and it has always been a succes. I don’t know where you are located but in Denmark it is easy to either buy a refoaming kit or you can have many shops/dealers to do it.

PindsenBRONZE MemberHi,
I can very well end this thread by saying that I figured out how it worked. So the spring-back effect was controlled by the bronze metal spring attached on the P2 button but due to metal fatigue it had no effect anymore so I had to create a new spring effect. It is impressive these small detailed engineering techniques B&O has created over years.Location: Denmark
PindsenBRONZE MemberHi,
Thank you for the description, I had not noticed the ability to pull the knobs off like you mention. Then I might have another issue, and that is that the buttons do not thay IN when being pressed. There was a small blade spring that has become loose, it was attached to the P2 button on the side but despite trying mounting it differently I cannot make it work – I assume it have something to do with the plastic thing moving underneath the buttons?
Can you help with that also?/Pindsen

PindsenBRONZE MemberHi,
If you get hold of the service manual you will find the whole list there with part numbers.
