I hope you can help. My Yamaha receiver is about ten years old. It worked fine until yesterday when it immediately shut off for no reason. I turned it back on and it clicks off again. I tried this more than five times. Any advice?
Your Yamaha might be at the end of its life and is certainly well past its warranty period. My suggestion is to not turn it on anymore. There is obviously something wrong with the unit and you should get it checked by a qualified technician if you wish to continue using it. Alternatively, it might be time to start shopping for a new receiver.
