AppleCD 600i take-apart?

[protocol7]

So, once again my latest conquest has a problem. The drive won't read anything. No activity light if I put in a CD. If I try to mount a disc in it with SCSIProbe it just makes a single "naaah" click.

I've tried to open up the drive but haven't gotten very far. Took off the bottom plate, removed the front bezel and can't get any further.Trying this on the offchance that it's just dusty and needs a good cleaning out.

Any tips?

A dusty lens is the most likely culprit, or perhaps a loose ribbon cable. You may also want to check that the spindle motor is operating properly when a disc is present.

Outside of that, the problem is caused by a hardware failure or software issue.

Take apart: If I know this drive correctly, remove the bottom screws and then slide off the metal cover.

I was hoping it might be something like dust but if it won't spin a CD I'll need to take it apart to get to the lens. And as I mentioned, once I remove the bottom plate and the front bezel I can't get any further. The innards won't budge. I can't see what's holding it all in place.

It won't even boot a CD so I guess we can rule out any kind of software issue. I have the drive from my 5400 attached to it now and it's all working fine so whatever the issue is, it's in the drive and not any other part of the system.

BTW the actual drive model is a Matsushita CR-504-K. Google throws up nothing for how to open/service these.

I had another stab at this and managed to get the darn thing open this time. The circuit board (and internals) are connected to the (top and side) metal casing by 4 plastic pins. Using a flat screwdriver I was able to prise them out of the casing. Then I could lift the drive internals out. A careful dusting down has brought the drive back to life.

Here's a pic to try and illustrate where they are. Wedging a screwdriver between the black plastic above the circuit board and the metal flap allowed me to me pop the plastic pins on the four corners, separating the drive from the outer casing.
