I have a Yamaha HTR 6130. Today both the front right and left channels just stopped working. I tried switching some wires around and its not the speakers because they work on the other channels. The unit is about 1 year and 1 month old. Any suggestions on what to do? I guess it's not made like my old Onkyo that I had for 22 years and still worked when I got rid of it. I'm going crazy because I can't play Call Of duty 4 with out my surround sound.
