My first receiver I bought for our living room about 4 years ago. I have since wised up and have a Yamaha HTR-5960 for my so called man cave. The receiver just quit one day and I haven't messed with it since. I don't really want to buy a new one (due to the birth of twins). Could someone be kind enough to tell me where to get a wiring diagram of tell me what to look for. Thank You.
