That can always happen, unfortunately. But the hard part here is that unlike with the VCR-sized CD-i players, everything in the 370 is tightly packed and you have to remove the pcb in order to remove the drive mechanism. The rest is not that hard. Remove the cover from the drive mechanism, clean the steel rail on which the laser moves, and re-grease it. Just don't touch the lens, nor apply any force to the moving parts.
