hi I stll have the problem with my beocord 9000 have taken advice from member it has new belts moter runs checked wire and conn the mpx is in the out position and the level is on line and the 9000 is set to amp but I still cannot record onto a blank tape there is no ppm showing plus on a recorded tape there is no sound or ppm showing is there something else I should look for ? thanks any help would be greatfull shaun
Having checked the things you mentioned, I would say the problem is likely in the electronics (somewhere in the PCBs of the deck). It could be a bad solder joint somewhere or some failed components. The easiest components to change are electrolytic capacitors as they are also prone to fail with age. That is not guaranteed that those are the problem here though.
If you have an oscilloscope you could try checking the points where the audio signal travels through the system and verify the signal is present (or missing).
Once you get to this part of the diagnosis where the problem looks to be electrical, it gets a little more difficult to find and repair.If the deck does play cassettes okay, then you can focus on the record stages of the electronics.You have the service manual with schematics, right?
hi sonavor no on repaires I am a novis ok with belts and cheacking would you say it a dealer repair
I think most dealers will have little idea what a Beocord 9000 is let alone be able to repair it! Maybe someone on here could assist?

No problem. The Beocord 9000 was Bang & Olufsen's top of the line cassette deck when it was in production. Quite expensive. So it isn't a piece of equipment that you just open up and easily repair without some study or training. B&O made it nice where changing the belts is easy but once you get into an electronic problem, you meet more complex things.
I don't know where you live but I would recommend finding someone that has experience with the Beocord 9000. A lot of new repair shops may not have any experience with cassette decks at all.
hi sonavor uk London as peter said most dealers have never heard off a 9000 shame it the best one b&o ever done they just whant to sell you a new model
Yes, you and Peter are probably right. However, since you are in the UK, there should be a number of Beoworld tech savvy folks there that could help you out. Or, you can send it to Martin (Dillen) in Denmark. Send him a private message via Beoworld (conversation) and ask him about repair options.

hi sonavor thanks for your help I will ask martin and see what he cames up with and just a quick one until the 9000 is sorted I brought a beocenter9500 put a tape in and it stuck and wont turn does that needs new belt and how do I get the tape out ?

It definitely needs a new belt. You are aware that the Beocenter does not have an "eject" function like the Beocord..?You should be able to just take the cassette with two fingers. UNLESS the tape-heads are out and stuck in the cassette. Then you'll have to open the Beocenter.
hi stffen thanks for your help on the bm 9500 im told that the belt are no longeravalable ? from b&o is there another sauce I can get a belt from yours shaun
B&O haven't got them - for some reason they make parts like this obsolete about 10 years after production ended, whichis pretty much when new belts will be in highest demand. One wonders.But I have correct belts for the tapedeck in your Beocenter 9500.Email me.
Martin
hi martin yeswill buy the new belt I am a bit off a nut for B&O brought my son a 9500 he had the same problem tape stuck in deck still need your advice for my beocord 9000 it great to now I am getting somewere at last
Beocord 9000:
Bring it out of standby.Display lights up?Motor runs ?Capstan runs ?When you insert a tape and press play, the tapehead bridge engages with a quite heavy "klonk" ?The right tape reel (the take-up reel) rotates a bit ?The tapehead bridge disengages ?
hi martin bc9000 display lights up yes moter runs yes capstan runs yes tapehead bridge engages yes the takeup reel rotatea yes and the tapehead disengages yes but still the same ? cannot record or playback and no ppm showing in the record mode the no store flashing all the time did you get my email for the belts for the beocenter 9500 ?yes I need to buy from you let me know how to make payment shaun
Yes, I got your email, thanks. I have also replied to it.
Check solder joints where connectors are soldered to circuitboards.Put a scope to the signal path and see where the signal gets lost.Since it is affecting both channels it will have to be a common component or circuit likef.e. a missing voltage around the Dolby ICs (which wouldn't be a first).
hi martin not sure which belt I need as yetits type no 2507 1986 model if that helps if not let me know a.s.p and I will open it up never opened one before so I willstart reading up thanks again shaun
