Quick video 

Hello...

I just got a Beogram CD 5500 working, so maybe my thoughts might help.

First thing I noticed on your video is that it sounds like the CD is hitting the tray.  This will stop the player from reading the disc until it finally gives up.

The rubber suspension for the mechanism is probably badly degraded.  Although the suspension does have provision for height adjustment, it probably won't be enough.  Beoparts does sell a repair kit for this.  

What I would do before ordering it is to adjust up the existing mounts so that the lower face of the disc  is 0.3mm above the higher part of the tray (should be quite a bit above the recessed area).  Most likely, the range of adjustment will not be enough, so consider shimming the mounts up so that the disc can spin  without any contact.  If this restores operation, then I would order up the repair kit.

If the player still doesn't work even with the disc running quietly I would then start checking voltages.  Mine had a cracked solder joint on the -9v rail , and there is a  capacitor on the focus board that likes to fail - just search for Beogram CD5500  C2103.

Good Luck!  Mine sounds awesome...

Hey Keri,

You were spot on, it was the -9v rail.  D19 5.1 zenner had failed on board 30. 

Its now all up and running !! :-D
