I have a Beogram 4002 Type 5503 that I pulled out of storage and hooked up, which used to work great, but now the tracking seems to be messed up. When I power it on, the tone arm moves to the beginning of the record, stops, slowly starts to drop the needle but then the needle does something unusual and starts tracking way to the left, while at the same time, the carriage starts accelerating quickly towards the end of the record before the needle actually comes in contact with the record. While the needle does drop down, it is just barely not making contact with the record (hence no sound). Not really sure what happened, as it used to work great. Any ideas?

Check that the tonearm is properly hooked in, there may also be something wrong with the lift/drop mechanism. The carriage movement is triggered by the tonearm listing to the left, so that is OK.

Check that the tonearm is parallel to the sensorarm.

Soren, How would I go about checking that the tone arm is hooked in properly? 

 

Martin, when looking at the two arms when the turntable is off, it looks like the tone arm has shifted slightly left towards the sensor arm making them not parallel. I don't recall that being correct...is it? How would I fix that?

Is there a way to adjust the parallelism of the tone arm or is this job best left to a professional?

The tonearm is balancing over 2 points (at the same time these 2 points, grub screws, are parallel adjustment as far as I could see in the manual). If the tonearm is not resting properly on one of these points you may get the failure you are describing.

I´m not familiar with the 4002, I have a TX2, and they are different constructions.

There are manuals onsite for silver and gold members. Sorry I cant help you more, but maybe someone else can chime in.
