Crackling sound in output

I just purchased a used MCD 7008 cd player. I get a crackling sound from one of the analog outputs. I tried changing interconnects with no success, I switched the interconnects on the outputs from left to right and the crackling sound follows the switch from one side to the other. When I swithched cd players the sound went away eliminating the amplifier as a cause. Does not happen on all cds, maybe 50% of cds cause the sound to present itself. Contacted the seller and there was no issue in the past. Item was shipped cross country. Any help would be greatly appreciated.
Check for a crack or short in one of your CD player's output connector (rca female connector). This may have occurred during shipping.
