On the display, when the discis moving I read 00, when it stp nothing..... only the number of track, but not the real track on the CD, evry led of track from 1 to 20 are on.

I have open it, and the problem is that the laser arm does not move. For these reason after 2 second the disc is stopped.
Now, how I can resolv these problem?
Somebody have the service manual?

Bye

Hi,
When you say 'doesnt move' - do you mean stuck fast / jammed? or you saw no movement?

No movement, but the arm is not jammed.
Usually I know when you turn on the player, the arm go to the begin, read the cd and then the palyer is ready for play the CD.
In this case no, if I move the arm in the middle and then I turn on the cd-player, the arm remains in the middle

Hi,

Service manual is available via EBay from CAS Eur.10.95

I have found them very quick.

Early Philips cd players suffered from poor soldering on the ground plane which resulted in various faults. Look for what appear to be jumpers with a blob of solder on them. They connect through to the other side of the board. You need to solder a fine wire through the hole, soldering both sides. while you are at it, check for obvious dry joints.

If you can get hld of another cdm1 mechanism, eg from a cd104, you can check the tracking motor by substituting

Ok, I have another CDM1 from cd-84, I can try to change but the connectors are a little bit different.
Tomorrow I will check all soldering.

Thanks
