| Disassembling an AppleCD 24x CD-ROM drive |
Posted by: EvieSigma on 2017-03-02 07:24:44
I'm trying to take apart and clean the AppleCD 24x CD-ROM drive from my 9600 but I can't actually seem to get at the laser assembly...I've taken all the screws out and still can't get the top shell off, and I can't find a guide anywhere online on how to do it. Can anyone help me?

Because there are 2 hidden clips right where the screws go through the covers on the bottom. If you look really really closely, you will see a tiny plastic tab sticking up next to the bent metal screw tabs. 1 on each side.
Push those to "clear" the tabs and poof she pops apart.

Got a picture? I managed to get the black plastic bit to disconnect at two corners but not the other two.

No pictures. All my stuff is put back together/fixed.
Depends on the drive, I have only found 2.
Also the tray has to be open, and the front bezel/faceplate has to be removed.

Ah, didn't know the tray had to be opened! Thanks for that.

Well disassembling the drive and cleaning the laser didn't make the drive work, but I appreciated the help nonetheless!
Guess I'll try out one of my older, slower drives.

Well I knew that wasnt gonna work. lol.
The laser itself is weak and you will need to adjust the output level of the laser diode itself, which is a pot on the side of the laser. Thatll get it going for awhile at least.

Oh, you didn't mention that before. How do I adjust the pot, just with a little stick?

very small flat blade screwdriver. Tweak only a tiny bit at a time. If you go too far you risk burning out the diode.
Plus in the beginning I wasnt sure what you were attempting to do other than clean the drive, maybe the tray was sticking? One could only assume.
If you said, Wont read discs, then I would have said the optical pickup is bad and needs re-adjusted.
Anyways, I got an 8X drive that has a bad RF Amp IC that I need to fix someday.

Yeah, the drive doesn't read disks. Found this out the hard way.
It spins up, spins down. Never actually stays spinning to read the disk like a CD drive should.

That means that it can't find a disk... Or can't read it. If it could be read it would keep spinning.

It definitely can't read it. These are known good disks so it's clearly the drive.
