Yes that is correct, over a period of time the laser becomes weaker and gets to a point it will not track, the second common problem the pladder motor that the disc sits on becomes defective and stops working. To fix this will require a brand new assembly that would not be cost effective to repair, but you can attempt to clean the laser lens with a Q-Tip and rubbing alcohol very carefully which might bring back the system.
