Hello, First unplug the Bose system for 60 seconds, then plug it back in to clear the processor and see if this solves the problem.
If not, then the issue you're having is due to the laser lens being either contaminated (dirty), or faulty (scratched or mis-aligned).
Follow the steps below to determine and attempt to cure the issue.
You can try several methods of cleaning the laser lens to see if it helps clear up the problem. The first is to purchase a CD/DVD laser lens cleaner disc, and run it through the system several times.
If your player is not reading any discs at all though, then try purchasing a can of compressed air (available at PC or AV retailers). Blow the compressed air into the disc slot liberally to remove any dust or debris which could be covering the laser lens.
If the CD player is still not reading discs, then the lens or transport mechanism is faulty and would require repairs.
In this case you would need to contact Bose Service, as they are the only ones that repair their systems:
