Hello all,I am new on here, and my B&O love started in the late 80s with my 3300 series of Amp/tuner, CD & Tape. However, I've more recently acquired (amongst other things) a BeoCenter 9000 as a result of a moment of temporary insanity where I was gripped by a nostalgic urge to surround myself in broken 80s B&O.Previous owner had it for 27 years and after the CD packed up a few years ago he hauled the 9000 from his home to his clothing shop where it had been ever since, used six days a week as the shop's radio.He also said that in the past he'd moved house with it several times, so cutting a long story sideways, it's not had an easy life. And apart from having glass panels reattached and door mechs fixed a while ago, it's had no care or servicing. On setting up I have found the CD isn't working. When you load a CD, it tries to read it for a couple of seconds then stops and the door opens.I've tried both new and older CDs but neither plays, same goes for lens cleaning CD. Gently cleaned the lens with a 'just-damp' cotton bud of window cleaner too but it just isn't interested.Kevin (my partner) carefully opened the system & with more cotton buds than I care to count, I've removed the accumulated dust. Poor 9000 was filthy having been in the clothes store..We have searched this site and think in all liklihood there is a capacitor problem (C2103 - are there more?) so would like to buy cap(s) and some advice please on replacing, as well as removing the old one(s) would be great.
I read that member 'Dillen' sells these? Kevin has a basic multimeter if needed, and a soldering iron, but in his words, only 'schoolboy' soldering skills. He's happy to tackle capacitor replacement with guidance tho, so I hope someone is willing and able to assist, photos may also be helpful. He's more technically minded (computer programmer background) than me, but I am the arty/practical one!Not sure what info is required regarding cap kit but the BC9000 is type 2501, serial number 04775927, with the number on the transformer 8013395 if that helps.If more details or info is required, please let me know.Looking forward to any advice it will be sincerely appreciated.Thanks in advance,Catherine (& Kevin!)
You're right, it's very likely that capacitor. Replacing it is very easy, but if you feel uncertain about how to do it perhaps asking someone with a bit more experience might be a good idea.
The cap itself is dead cheap but it's recommended that you replace it with the exact same brand/type (although many report that using any old cap works too). I'm not sure if Dillen has them, but if he does I suggest you get it from him. Then it will be the correct type.
Go on youtube and look at some soldering tutorials, and judge for yourself whether attempting it is a good idea.

Good afternoon Johan,Thanks very much for your prompt reply and advice.We've had a look at some soldering tutorials and I think Kevin will practice later on some old bits of pc boards he has laying around to get a feel for things.We've successfully tackled an assortment of repairs over the years and given life back printers, my imac (replaced a power supply), fixed a faulty switch on 'dead' flatscreen tv as well as mechanical items such as bikes and old sewing machines. Not always easy, but by with care, not rushing and doing thorough research, it's always done the trick for us. The job satisfaction you get from these restorations is easily worth as much, if not more, than the cost of replacements, whether they're new or vintage.If Kevin isn't happy with his technique then we'll call in the services of his dad or brother. Unfortunately they aren't on our doorstep but will likely see one or both of them over the Christmas period. His Dad was an electrical engineer for 20+ years at the BBC and brother builds and installs seismometers so both are more than capable in the solder department.Thanks again, Johan, I'll contact Dillen / Martin and keep this thread updated.Best regardsCatherine
Quick update: I have been in touch with Martin (Dillen) and sent him details of the servo board number to enable him to put the kit together. Am very pleased at how things are progressing so far
Great! I'm sure you will have it up and running soon.
Let us know how it works out.
Let's hope so!
Thanks for your support, Johan. I'll keep the thread updated after the caps arrive

Hi,
It's Kevin this time round, I replaced the capacitors as supplied but this has unfortunately not fixed our problem,
I have posted a vid of the 9000 loading a cd;
https://www.youtube.com/watch?v=jfDsgu4EEbU
The door closes & motor starts spinning, but it cannot read the cd, no error message just reads '0.00'.
Any further ideas out there ?
Thanks
Kevin
Hi Kevin and Catherine,
from the look of your video, the CD is not turning at all - the CD has not changed position. On mine, if I move the lens gently and then try to play, invariably, it will play OK for the rest of the day. You should check your new capacitor mounting again and check for any cracked solder joints. Does the CD sit properly on the holder? Are you sure the CD motor is working? - based on your video, I would suspect that the CD is not spinning.
Dave.
Hi
I would check solderjoints on powersupply capacitor board right next to CD before transformer, it requies some dismalting, but not anything impossible if you are careful and sharp.
blah-blah and photographs as needed
On those Philips-sourced chassis', the grey interconnect wiring was a major problem. On every one which came in for repair, I rebuilt the grey cable assemblies, without batting an eyelid.
If you have a look at the grey plastic connectors, and see green oxidized paste around the connectors, very likely that the cables have disintegrated to the point that they can no longer carry the current, hence no motor turning.
That unit uses a Hall-motor, which is highly dependent on good current to be able to turn.
I'm happy to rebuild the cable assemblies for you if it's too much of a job.
Yes, and those cables also suffer loose wires.
Hello Dave, Orava and Menahem,
Thank you all for your replies.
Dave, unfortunately moving the lens didn't change things, but thanks for the suggestion, obviously everything is worth a try. Funny how these machines have their little quirks :) We have been up to our eyes with various upcoming Christmas events and so haven't looked at the cd over the past few days but will certainly examine the cap mountings and check solder joints with a magnifying glass. CD seems to sit comfortably in the holder. I can't say for sure about the motor, I can hear a whirring but will speak to Kevin when he gets in later and ask what he thinks. Funnily enough we also have my old Beogram 3300 which the cd DOESN'T spin on, but will investigate that later - I won't confuse things by discussing two different units on the same thread!
Orava, thanks for your suggestion. Will ask Kevin to have a look at solder joints on the other board, He is more confident when it comes to taking things apart, I'm a scaredy cat and really only any use if a second pair of hands is needed to steady or hold the guts!
Menahem, thanks also for your input. We've seen your posts on here and CondorAudio website, your restoration pages are very informative, and we'll definitely consider your rewire offer if we see any signs of oxidisation (or loose connections, Orava). Having read through your Philips Marantz CD650 CDB650 restoration, I assume replacement of the grey wires to the stocko connectors is what you are referring to?
Will report back with updates on all these suggested points as soon as we can. Thanks again, your support and advice is greatly appreciated.
So back to looking at the Beocenter CD problem, after xmas.
Have checked the soldering again for the replacement capacitors on the CD servo board.
The CD starts to try to play but disc doesn't spin (title can be seen in same position at start and end). Series of relay-like clicks, finishing with the (empty) tape making a noise at the end. Any thoughts?
Please see video posted on you tube;

My first choice is the grey wiring problems, or a bad solder joint.
But you should be doing the tests with the top cover open, and the insides exposed.
Have not managed to find much time to investigate further this month, they grey wires look ok, have had a quick look & check of my soldering, and look for cracked/dry joints on remainter of pcbs.
There is a fold in the servo ribbon.
We have a Beogram 3300 CD player, also not reading CDs which I will try exchanging motor & servo boards if poss, will update.
A "quick look" is not good enough.
You must connect them in circuit, and measure voltages at both ends of each wire.
Only then can you determine certainly whether each wire is OK or damaged.
Had the same issue. Buy a Philips blue cap 33uF for a few pennies and it's back in working order.
Brengen & Ophalen
We have finally found a working CDM2/10 mechanism to buy (Thanks ebay) since the ribbon wire to the servo on the current one has a fold/break,
I want to swap over the mechanisms but the cd spindle on the old one has spring on the top which the CD is held down by,
but the new one does not, you would need a clamp above to hold down the cd (like Beogram 3300).
So can I remove the spindle from the new mechanism motor & replace it with the spindle with the spring from the old one ?
the spindle is held on the top of the motor.
Kevin & Cathy
It is exterme fragile!!! I would not touch it. Instead I would swap laserarm mechanics if must. Beware, if you dont swap servo board, you have to adjust laser current.
good morning to all of you help me when I insert a CD into the player the player correctly reads the tracks on the display to scroll through the tracks and also the time but no sound comes out of the time and then suddenly everything works fine reads the cd and the sound comes out for days integers then suddenly begins to read properly but without sound problem seems mainly occurs after the BeoCenter 9000 is removed electricity as if he lost memory or do not know what I 'was told that there is' a code to put with the remote control to reset it and 'it? I clean the laser lens although I do not think the problem is because as I said when he decided to read the cd reads them perfectly original and burned help thanks
If 'CODE' is displayed you do this:

You could try replacing the Li-ion battery.
thanks dave can you tell me where and 'placed the lithium battery and replace if easy thanks peter
No, I've never done it. There will be other threads if you search the forum and if you look under the 'products' section you have access to all of the service manuals.
Not very difficult, but you have to take processor board out, it is soldered on edge of it.
chi puo' mandarmi foto di dove sono i condensatori elettrolitici e la scheda di controllo che servono al cd del beocenter 9000 voglio provare a cambiarli per vedere se poi tutto e' ok grazie
who can 'send me photos of where the electrolytic capacitors and the control board serving the cd of BeoCenter 9000 I want to try to change them later to see if everything is' ok thanks
The BeoCenter 9000 used the Philips generic CD PCB's, which were installed in thousands of different brand machines all over the world.

thanks for the news not being an expert I would like if possible a picture of the internal BeoCenter 9000 which shows the parts to be replaced to run properly again the cd thanks again
