The question is whether your CD player is capacitor coupled or direct coupled.
If it's capacitor coupled, the problem is exactly what others stated here, a leaky or shorted output capacitor.
If it's direct coupled, the problem is the output bias on the CD player has drifted, resulting in DC at the output. The bias has to be adjusted by a technician.
