Question about Yamaha RX-V661 Receiver
The receiver's display screen appeared dimmer than normal last night and now when I turn it on I can briefly see the message Main On then the display goes black. The receiver seems to work normally otherwise. I unplugged the unit for a few miutes then plugged it back in to the outlet, but this did not help. The display still goes out. What else can I try before sending it in for repair?
I have a rx-v661 and the display went dim. I found out what set of diodes and capacitors handle the display power. It is on the "MAIN" Board at the bottom of the amp. The board is connected to the large heat sink in the amp. On that board near a small heat sink you will see four diode (D1001,D1002, D1045 & D1044) and four caps (C1000,C1001,C1002 & C1003); three of the caps went bad and two of the diodes. I replaced all of them to play it safe and the next thing you know, I have my display back. You can order the parts on-line. Here are the part numbers :

Whats wrong is a bad capacitor. This is why when you turn it on you see the display for a little while, then it start to fade away. Unless you have a wiring diagram for this unit and know how to solder, your going to have to take it in for repair. You can try to check every capacitor, but have you seen how many capacitors are in that baby!!!! I hope this help. Good luck!!
