CD-ROM laser woes

Post by inflater »

Hi,
just found an very old CD-ROM drive somewhere, I remember it's the one that I've got with my third 80486 PC in 2001... :) So I placed it to my testbed, but it wasn't reading disks: the motor just spinned up and immediately down, 3 times. Then, I didn't hear anything at all, and the "cleaning CD" thing didn't work. I remember that my dad always took it to his friend for "screwing on the laser", but I didn't understand what he meant with that. So I googled and found that I shall screw the laser trimmer thingy a bit, but I didn't knew how it looks and where it is located.

So, after 7 years I've unscrewed the drive, searched 3 minutes and ultimately found a little "screw" on a white 4x4mm plate, located on the laser module next to the laser data cable. So I adjusted it a bit and put the drive into the PC. Yay, it works! :D

LOL, that was the first time I've managed to hardware-repair something PC related... :lol: (Usually, I'm the type that can unscrew something and screw it back again, non-functional. :lol:)

Did you managed to repair some PC components similar way? :)
Regards

I used to do quite a bit of pin unbend-ification in the old days when plastic pin guides were rare.
