Left MPC stereo out making weird distortion

its a real weird distortion that comes out every single time a sound comes out of the left stereo out, is there any way to fix it easily ? Anyone know where I can find a replacement part like going to a general store ? Instead of going all out and getting it delivered from a far away specialized store ?

Sounds like a technical fault, no easy fixes

You might want to start at your cables. Make sure they are not shorting or anything. Are they Balanced? You might be picking unwanted noise from something else.
