Helle all
I am working on a Beogram CD50 where I have issues with the CD carrige movement. It is very slow, and when it reach the point where it has to lift the CD clamper it stops.
I have replaced the Belt, and cleaned and re lubricated all the gears for the CD carrige movement, and this has helped to some degree.
Also I can move it correctly by hand , so pretty sure I ahve alligened the gears correctly. This also verifies when I try to apply 5V to the CD carrige motor from an external power supply which makes it run smoother and also it is able to lift the CD clamper with this voltage.
So now I am A little in doubt what is wrong:
- Is the motor voltage correct, I Measure 4V/-4V when it is moving, but in the service manual it says 5v/-5V before the transistors around the motor, and as mentioned it runs smoother with 5V applied to it?
- Could the motor also be prone to old lubricant that needs to be cleaned? If so what is the procedure for that, and do I need to dissasemble the whole rail system for the CD carrige to take of the motor?
Thanks in advance
