    so i love my new 27"; it's simply fantastic.... so far. i encountered a problem when i plugged in a 1/8 to RCA to go to my surround sound system. There is a loud humming sound coming from the speakers when i connect it. i tried to wiggle it and push it further to no avail. the sound was still there. i tried using another cable and the sound was still there. then i tried plugging in my headphones, and they WORK FINE! what the hell is going on and how do i fix this problem?

    Thanks in advance =D
