Hi all, New to forums, hoping you guys can help me. I have a Yamaha HTR-5540RDS surround amplifier with the supplied subwoofer/speakers, hooked up to a DVD player and sky +, and a 52 inch Toshiba projection TV. Surround has been working fine for a year or so, but about 4 months ago, the back speakers just stopped working, I have been trying everything to fix them, Im 99% sure its something Im doing wrong rather than a fault, I rewired everything, checked cables, adjusted options, but all I get is the front three speakers. Its connected using optical, and all the speakers are connected direct from the subwoofer, fed into the subwooder from the amp, and then fed out to the speakers. i also tried connecting it direct to the amp, but that failed aswell it may be something as simple as an option in the menu, but having lost the manual, I dont know what to do. So I thought I would ask for help, if anyone could tell me how it should be wired, ie direct to the speakers, or through the subwoofer, or any ideas of what I could change to fix it I would be very great full, as I said I have been trying to fix this for months, asking you guys is my last hope. Thanks.
