Im not sure what forum this belongs in so I chose this one. Feel free to switch it if I was wrong.
I have a Boom chair for my video gaming. I has a very loud humming when it is plugged into the wall. The humming lessens when you touch the faceplate that has the RCA jacks, volume control and tone knobs on it. I figured it was a ground problem so I opened it. There is a set of four wires that connect two boards, when i touch these wires the humming gets worse. I can't see any breaks in wires or connections. The plug that goes into the wall only has two prongs, no ground. Any ideas what I can do to solve this?
