audiolab 8000 cd player mechanism

[spy1066]

Hi Guys,
I'm a new member looking for a workshop manual for the above integrated cd player.

The player is pre IAG (TAG) and I am trying to resurrect the unit by replacing the drive and laser which I believe is where the problem lies.


Can anyone help?

No service info but if you can quote the laser pickup used/mech details etc might be able to help.

Pictures maybe ?

Hi,
I believe it to be a Phillips CDM 12.4 and am still trying to get the original out of the player. Iit is encased in a metal casing which is proving difficult to get at.
Have you any info/knowledge of the type?

This is the CDM12.4
I have worked a lot on these... what is the problem you have with it.

Hi Mooly,

Thanks for the response.

Immediately at switch on I get an "error" message appearing. I am told that the reason for this is that the "drive motor" for the disc is seized and my intention was toreplace the complete assembly as shown in your picture. However, as I say getting the original out seems to be somewhat tricky. Any idea how much disassembling of the player is required to do this?

The motion associated with the disc tray seems to be fine working both from the remote and the button on the front of the player.

So that is the correct assembly then as shown in my picture ?

First things first. It would help for me to see a picture of the unit and what you actually see when you refer to this "metal casing". The CDM12.4's and the Philips loader assembly are usually easy to work on.

The CDM12.4 has two motors. One for disc which should be free to turn by hand. I have never heard of one seizing. The sled motor is under the mech and drives a worm gear arrangement.

You need to confirm that the laser assembly (the sled) is in the correct rest position at the platter end of its travel. The lens on the laser should move up and down three times quickly when the tray is closed as it sees if it can focus on to a disc.

If the error message appears instantly you power on there may be another issue. The CDM12.4 was notorious for having problems with sticking and jumping caused by the grease solidifying... easily fixed if done properly.

This is the loader,

Hi Mooly,
Yes the assembly I have been given to replace mine with looks to be the one you show in your picture in your previous message. However until I can get at mine I can not be absolutely certain and that is the initial problem.

You mention tthe sled being in the correct position - the only thing I can see is the front of the disc tray which appears to be in the correct position when closed. Regarding the laser going up and down - once the tray is closed even with the casing removed I can see nothing of the mechanism as it is ll enclosed in the internal casing I described earlier.

I have taken som pics and I will attach them but at the moment I don't seem to be able to even find the route to do it. Sorry to be such a bore.

The error message is instantaneous at switch on.

Hi Mooly,

I am attaching some pics to assist (if it works).

The first gives an overall view and the internal casing I refer to is on the left side. The three attachment screws are just visible, one on the left side and two on the black bar on the right which runs from front to back of the player. Even with these removed and the screws for the facia removed there does not seem to be a way to get either the assembly out to view what is underneath or inside.

The second pic shows the view from the front with the slider extended.

I hope this helps.

Thanks for the pics. The drawer isn't the "normal" Philips loader that the CDM12 series pickups are normally used with. It looks like a DVD drive tbh with the metal can.

I think you are going to have to dismantle it a bit more and see just what is under there.
I found this about the (original ?) 8000 CD and this mentions a Philips series 12 DVD drive.

A service manual or circuit diagram would be a huge help. The fact that error shows instantly wouldn't normally point to a faulty pickup... but if it is a DVD drive then that's a whole different ball game.

It should come apart fairly easily, just make a note of everything you do. The metal cover might also be clipped in place as well as screwed but it's normally a case of unscrewing everything in sight. The assembly may well be held from underneath too.
