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!!

My display screen is completely blank, but finctions properly.
I had also exactly the same problem with the front display of my Rx-V661which was becoming completely blank... As mentionned as solution, I replaced the four capacitors handling the display power. Then, my display was back. (I didn't replace the diodes which were well working with new caps, so...)
I thought that problem was solved. But one week later, this problem was back and now, I haven't again nothing on front panel screen...
I suppose that there is something else which damaged the caps....but what's wrong?
Someone can help me?
I have the same problem. I have just ordered the diodes and capacitors as suggested. The ordering was easy enough. Now we'll see what happens ...
