Beogram CD50 Repair
8 replies
Hello BeoWorld,
I am new here but I have read quite a lot of posts on the repair of Beogram CD50's so perhaps I just need someone to point me in the right direction.
I have inherited a BeoSystem 5000 from my dad which I remember him buying when I was small. It has a few problems that I am trying to fix as it hold some fond memories for me. Firstly I am tacking the CD player.
This has the usual problems with the drawer unit so I am going to clean the gears following marking them up and replace the belt which all seems pretty straightforward.
My real problem is with the spindle motor which does the "chirping" sound but wont turn the CD. I have read that this is usually fixed by cleaning in IPA or some such.
Q1 whilst I can remove all the screws holding the motor and the board and the grub screw in the brass spindle. I don't know if I can remove the two plastic connectors from the wiring harness connected to the board easily. Are these simple pull off connectors or are they soldered on.
Q2 Assuming that I can get these connectors off how do I clean it, do I just dunk it in IPA overnight or some such or is there a special procedure?
Q3 The motor also seems to be pressed into a metal plate, is it best practice to press it off before cleaning?
Q4 If all this fails can I get a new motor/board etc and if so from whom?
I'm very grateful for any reply I get so thanks in advance,
Chris.
You might find some inspiration for disassembely of the motor in this thread where I disassembled the motor

Thanks Madskp,
I have cleaned the motor but it now doesn’t run at all previously it did run at least a little bit, I’ll take it apart again today to see if anything changes at all.

It seems that the CD50 spindle motor windings are now not connected to anything, I'm presuming that there must be some connections from the motor windings to the machine. So no wonder the motor wasn't working. Can anyone advise what to do next or perhaps somone has a spare spindle motor for a CD50 in their storage bins somewhere or perhaps someone would be able to rewind my current broken motor.
Could you try to post a picture of the place where you do not see a connection. Just to understand what the issue is

Here are a couple of photos of the problem. I am guessing that the PCB should somehow be connected to the windings of the motor possibly using the three solder pads on the PCB.
I don’t think that my dad ever had the CD50 working and he bought it about 20 years ago so the problem doesn’t come as a surprise to me.
Grateful for any help
Chris
Yes I think the motor windings must be connected to the three solder pads. You might be able to see some of it in some of the photos in this thread
