Hum

Just recently my MPC started to have a slight hum, mostly when I enter menue ie: program. Is this anything I should worry about?

it may actually be other gear closeby that is causing the hum... i used to have a computer monitor that would cause hum in my synth and mixer... i'd have to turn the screen off when i wanted to record... are you sure the hum is caused by the actual MPC?

yes its coming from my mpc. It doesnt happen all the time, but once in a while. Its not coming through my headphones or anything else.
