Buzz from Mackie CR4 studio Monitors

Hey everyone,

Bought a pair of used Mackie CR4 monitors and played them for nearly 4 hours or so yesterday.

Initially, there was no buzz, but I heard it later on.

At this point, there are two noises. 1)A buzz when the monitor is powered on.
2)A hum when the volume switch is increased from 0(basically off position).

These noises exist without anything plugged into the speakers (i.e no input) and no wires connected.

Any help to resolve this would be greatly appreciated.
Thank you!
