Hi ,i have an old cdrom,i am trying to repair,the problem is:it won't spin de cd,the laser head assembly is moving ,it just wont spin the disc.I checked the cable connections to the motor they are ok.
Any ideas what could be the problem?
There are many possible problems:
dead motor
dead motor controller/regulator
the drive's internal controller is partially defective
PCB fault
...
If a CD drive electrically fails on me I keep better ones for spares and scrap the more generic ones. Only few drives are worth the hassle of troubleshooting and repairing imho. Sorry I can't be more helpful.
I've a drive (cr562) that won't spin up because it can't get a focus lock. As I understand it, the first thing the drive does is make sure it can get a reflection from the disk. If it can't get that then it doesn't spin up. In my case, I think the cause was the lens coming unglued, which I think is basically not fixable without equipment to focus and calibrate the read head. But, as Doornkaat said, not spinning can be caused by many things.
I agree that it still can be the laser/lens that causes the problem. The first thing to do is cleaning the lens and the prism underneath, if it's accessible.
