butteredtoast

i got the 4.1 promedia about 1 week ago, and the second day, i noticed static,hissing, crackling, mainly crackling. after some experiments, i realized it was mainly coming from the front left speaker. plus, when i disconnected the left speaker, none of the others were hissing or crackling. i tried using different speakers, different wires, but it always crackles. its so annoying!!!!! please help.
