I have problem with BeoSound Century / 2000

Cassete plays for 3 seconds, reverses and plays again for 3 seconds and then shuts down.

Does anyone can help me?
All other functions (radio, CD, ..) are working without any problems.

Is it the same with all cassetes used?  Does the tape fast forward and rewind OK?  Have you cleaned the tape heads?

I don't know what drives the tape counter on the Century - belt or other sensor?.  I know that on other K7 machines that if the belt is broken for the tape counter you do get the tape stopping so that is a place to start looking I suspect.  The service manual will probably help you.

Hi Marexy,

 

This is the EXACT problem that I have with my Century!!! It developed the problem when it was four years old. The cassette deck had very little use. 

I'd love to know how to rectify this fault!

it has a sensor for counter. Like avio propeler or how could i say .. :)

behind these plastic part is sensor. The sensor works ..it give 3-5v hi-lo signal.

I have service manual ..but i do not know where to look for error.

maybe is microcomputer fault ? :(..or some stupid litle hiden error :)

I can not believe that no one has ever had the opportunity fix the error that is obviously serial.

Since I am not expert'm looking for tips and help :)


I do not use a lot of cassette player (almost never). but I would like to fix it.

Maybe check the take-up torque and adjust if necessary.  You need the torque tape to do that though so would need to be taken for repair (adjust 1635 on PCB7 to 45-50g-cm.

I suppose the easiest option is to replace the drive belt (number 9455/2732111) first with a new one to see if it helps.

I don't think this has ever been discussed here before so can't call 2 instances 'serial'.

Yes, same here, my tape deck had very little use but again, i'd like it to work! Even though basic, the cassette deck was capable of making some really excellent recordings using ferric oxide cassettes.

Out of interest, mine was bought in December 1999. I had three in the first week - all problems with the sliding door not opening.

I think this must have been a bad year for B&O as the CD player continuously jumps,, the plastic casing vibrations with medium volume and the electric glass door doesn't work if the room becomes slightly cold. And the cassette deck doesn't work.

Very bizarre as the catalogue mentioned attention to detail and the high reliability of the glass door which was tested 150,000 times??? They obviously forgot to test them in 1999.

Hi

Cassettes for the torqu moment I have none.

Flat belt is tight in place. I think that is not a problem point.



i repair Dors ... try to clean sliding along the surface, and applied to the surface new soft technical greese.
Clean the door sensor, and for me it worked and then everything works ok.

The door issue was a known problem and is easily solved by swapping 1 part.  See service manual.  This was changes after the first year or so of production.  Your Century issues seem to have all come in one machine as you know many others have had no (or little) problems.  Most cassette decks stop working after many years - belts rot, gear siezes due to lack of use or lack of maintenance.  You can't expect everything to work all of the time for an indefinite period.  Things age and eventually cease to function properly - cars, white goods, electronics etc etc.

Are both tape reels rotating when it runs (even if only very little) or has one stuck ?
