Hi Craig

I have had similiar problems with the sensor adjustment, but inside the sensor arm i have repositioned the bulb closer to the lense. It seems that the end of the arm the small plastic part with the legend on opens easily and can be slid out far enough to carefully reposition it.

The tone arms tracking to the centre I have experienced problems with this but adjusted the sensor and it has stabalised the motor and the arms tracking movement.

I hope this makes sense.

 Cheers

Thanks Kevin, I will give it a go and see what happens.

Craig🙂

Oh Craig

 I forgot to mention the solenoid adjustment at the base of the tone arm can be very tricky to adjust but there are loads of threads on Beoworld describing this, the slightest movement left or right can make the arm track backwards it seems or scanning towards the centre. It may be that you can do tiny adjustments to this until it tracks better and then tighten up again.

I have to stress though this is a patience job, and it can take a while to get right.

Cheers

Thanks again Kevin, I have not had a chance to look at it since you last post. When I do I will try both, although I am sure it is the lamp that is the problem as the solenoid does not even try to move now.

Hi Craig

 I realised I said adjustment of solenoid, when I meant moving the diaphragm by lossening screw at base and moving this left and right slightly, its in the  Beogram 4002-4004 manual sect 3-5

Hope you got this sorted!

 Cheers

Still not got round to sorting it out yet Kevin, but thanks for the update.

Craig🙂

Ok, so this is now my Beogram!

I cleaned the light lense as it was all murky, and have tried various positions for the lamp inside the arm, but it still fails to 'see' the record. The arm goes across the LP, the speed changes to 45, hits the end, then returns.

I read that a marginal lamp can cause problems, this one still looks ok though.

Any thoughts?

Ok, So i've made a bit of progress... not meaning to though.

I took the main PCB out, to check for burned components, put it back in, and the arm will now will drop at the 12" LP position.

Moving the tonearm to the left though, the carriage will not follow, so there are still some glitches. If I put on a single, the arm still decides to drop at the LP position.

I'm thinking along the lines of recapping and seeing what happens after that.

Does anybody have a clearer version of the service manual? I can't read the schematics on the one on here.

Thanks,

Ben
