Default Philips CD960 problems

Hi, I got the problems with my CD960. When the power is turned on, the spin motor turns counterclockwise a while then stop and the laser head moved up and down several times with weak light. Does anyone know what is the problem with my CD960(cdm1)?

Have you tried to clean the lens? Sometimes after years of use they develop the fog that is easy to wipe out. If this is not it try to swap the CDM1 from another working player, it's not a lot of work since the bottom of the enclosure is removable.

Thanks for the suggestion but this is not the case. Is there any hit from the servo board?

Check the power supply especially the power to servo.

Thanks! What will be the root cause if the power supply is abnormal?

It is why to check the powersupply first. If one of the power supply (+12 or -12V) was failed, the motor will rotate in reverse direction (or no braking effect). And if the powersupply is good. You need to check the servo related circuit. First check the easiest parts first.
