I have recently had problems with my slimline V12 console reading backups, so i attempted to adjust the POTs on the laser. Then the laser wouldn't even attempt to read, so I decreased the voltage. Now the laser continually moves down the guide arm and and even tries to keep going once its reached the spindle, hitting the spindle making a clicking noise. I don't know if I need to purchase a new laser because it dead or the ribbon cable is loose from when I removed the laser to adjust the POTs. Any input would be greatly appreciated.
