Hi all- I bought a Yamaha HTR-5830 receiver w/ a surround sound system. The problem the the front two speakers. The center and surround sound speakers work. When i put the speaker cable into where the front speakers go and turn my receiver on, i think it shorts everytime because its just shutting off. But im sure that the wires are not touching, and im really not sure as to what i am doing wrong. Ive even tried switching types of speaker wires, to no avail. Im not sure why my receiver keeps shutting off, any help would be much appretiated.
