MPC 2000XL -- Headphone Issues

I am having problems hearing out of the left channel of my headphones, any suggestions? It's not the headphones, because when I plug them to other sources they work fine.

I have them plugged directly into the mpc's headphone jack, does anyone know if there possibly a setting that I am overlooking? Any advice will be considered, thanks

Could just be a loose conection. One of the great things about MPC's is that with a bit of mainanance they can last a long time. I advise you to get comfortable opening that sucker up. See if you can see a disconnected wire. Good luck.
