RX-V661 front display problem

Comment by Holyrider, posted on Jun 09, 2008 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?

    at source, caps of 50 V are installed. Do you think that if bad caps are replaced by new ones of 65 V, it will solve this problem???

Excess power supply demand from the display can cause the symptoms you describe. Unfortunately, the fix will be a new display if this is the case...accordianman

My Yamaha RX-V661 powers on when I hit the power switch. After two seconds it goes to stand by.

try holding the 'straight' and 'audio select' buttons and press power. What does it say on the front panel? Should say some kind of protect: I, DC, PS. This will help narrow down where your problem is.

The receiver works great but there are no longer any lights on the front. We checked the manual and can not see where there is a fuse or light bulb to change help

If on the front display it is either missing a voltage source (connection or bad part) or the display itself is bad.

There's a common problem with the Rx-V661 where a capacitor blows and then the display on the unit no longer works. It will start to display when you first turn it on, but fade out right away. This is because of a blown capacitor and a known issue for the Rx-V661.

No auto setup display on TV

For the setup functions you have to use either the monitor out (a yellow jack on the top-right corner of the back) or you have to use component video out. HDMI will NOT work for setting up the system. This is one complaint to Yamaha from all of us.

your receiver has zone 2 output which is operated independently of the main reciever. so you can have a dvd playing inthe main reciever and the tuner playing over the intercom. read about it in your manual page 89. in will hook up to 2 RCA jacks in the back Zone 2 out.
