When I hit "play" everything works as intended, but the tangential arm itself is moving too slow , After playing 1/3 of a record, the pickup arm is angled towards the center og of the record, maybe 10 to 15 degrees!!!

I cann see, that the spindel itself (the one advancing the tone arm towards the center) is moving in small steps, maybe 1/3 to !/2 a revolution at a time - is that correct or should it be a contious motion?

All buttons on the interface are working correct, but sometimes, the arm takes an extra journiy from back and forth from the start to the end point of travel, when I hit "stop" - could the issues be related?

So far I have replaced both belts, cleaned/lubricated and adjusted everything around the tonearm acording to the service manual.

what am I missing?

This sounds similar to this thread this week.  

/forum/beogram/beogram-6500-pickup-carriage-move-left-very-very-slow-and-stop

Have you checked over the comments 'Dillen' makes on that thread?  If you have cleaned and adjusted everything else then these are worth investigating.  The step motion is normal as far as I'm aware as all my decks do the same.  If you use the 'Left' button, does the carriage move freely all the way to the centre?  Or, does it pause at about the same point you mention?  There may be a physical block to the carriage movement, rails not aligned, clip broken etc.

I have clened everything, and there is no bumps or dirt on the spindel - it would also have been my first thought. When pressing the left or right button the arm moves freely, without haning anywhere .

 

maybe the spindel is slighty bend? Then I need to know how to dismantle it?

 

Luckely I have an almost complete second deck for spares

If the carriage moves freely, then I suspect 'Dillens' thought on the detector/lamp is what to look at.

Sounds reasoanble - but what shall I look fore - the light is ON on the tone arm.

I suspect that LDR is short for Light Dependent Resistor - but thats as far as I get

 

Bad tracking, either the lamp or the LDR or both.

Was the fault present before you replaced the servo motor belt ?
