LG GSA-H55L reports no disc in drive

Hi!

Any ideas on this one? I got an internal GSA-H55L DVD-RAM/DL drive, but all of a sudden it doesn’t work as it should. It doesn’t seem to be able to “see” any disc in the drive, no CD, no DVD, doesn’t matter if its blank or not.

What I’ve tried:
Unplugged and plugged in the cables
Updated firmware
Reinstalled drivers
Used Nero InfoTool to check if it says something else, but no disc as far is it is concerned.

Thanks for any help or pointers =)
