Beogram 4004 - Arm fails to lower!!!!!

19 replies

Need some advice with a Beogram 4004 I have just purchased. When I plugged it in I could hear the motor running but the platter would not turn. Just found the that the belt had come off, so an easy fix. Fitted it with an MMC10 stylus just to try it out. When I press play the arm moves to the start of the record but fails to lower. You can hear a click from inside which I assume is the solenoid working. If I remove the panels and try to use the raise and lower button I can see the solenoid moving. Tracking weight is set at 0.5g. Is this a simple fix? fingers crossed.

First thing - check the tracking weight is not set to zero. If it is set properly, it will need cleaning and lubricating.

It could well be the linkage between the solenoid & the tonearm Craig. You should be able to move it quite freely by hand. There are several pivot points which cease up over time. Just take it apart, clean the old lube off & reassemble with a touch of silicon grease. Not difficult to do & the linkage is fairly easily accessable.

How do I get the cover off that covers the two arms? Or can I clean all the parts with this in place?

Craig, if you view page 3-2 "adjustment of magnet coil" diagram in the service manual you can see the see saw (possibly pantograph??) arrangement of this assembly. It is the pivot points which can become stiff. It's a while since I did this on a BG4000 (same system) and I think I had to disconnect the solenoid first - not sure though. Martin will probably know.

You shouldn't need to remove the cover to do this.

EDIT:- try not to lose the screws eh?๐Ÿ˜Ž

Cheers Chris, I will take a look later tonight, just got to pop out for an hour so. You might be getting a phone call if I get stuck.๐Ÿ˜•

You'll be fine mate. It's pretty straightforward once you make a start.๐Ÿ˜•

Well I may have celebrated a bit too early. Now the arm loweres most of the time, seems to be getting better with more use. So I will see how that goes for now. My next problem is that when the arm gets to the ned of the record is does not return or lift. If I use the < button it goes to the end of it's travel and returns perefectly. tried cleaning the sensor lamp to see if that made any difference, but it did not.

NOOOOOOO. Things seem to be going from bad to worse with this one. Just thought I would have a listen to a record on it. So I connected it to my Beomaster 900. Pressed start now the arm goes all the way along to the end and returns. It won't even work with the up and down buttons. It is as if it cannot see the record. Could this be a problem with the lamp?
