calibrating 12X cdrom drive

Two months ago when i think to reinstall the MacOs my 12x cdrom drive cannot read ANY disk. I cleaned it with caution, but nothing happens.
I heared about a little device inside the drive that allows calibrate the laser intensity(i see it in other powerbooks). Exists any info about how to get it?
Replacements are too expensive.

Powerbook 3400c, Mac OS 8.6 or Earlier, 200 Mhz 48MB ram
