Right channel not working on yamaha rx v793 receiver

Sorry, it doesnt look like you can hook up an external EQ while still using the amplifier section of the yamaha. Instead, You would have to use the preamp out to go to 901 EQ, out of the EQ into another stereo amplifier, then to the 901 speakers. Personally, to power the 901's properly, I'd use another external amplifier. You will barley get 75watts per channel out of the receiver to power the 901's

I have seen this a lot of time on Yamahas, one of the channels are either a bit or a lot softer than the other, this happens after warrenty and you need to have it repaired.

The channel that is weak will either have a faulty transistor or a bad capacitor on it. Most engineers would test it by injecting signals into the circuit at different points. Working backwards from the front end. When the signal goes weak, you have found the faulty stage.

Thanks for all the suggestions guys.

I've tried using the balance for left and right speakers, and when the receiver is acting up with the right speaker having a low volume, I tried moving the balance all the way over to the right speaker. The right speaker volume will not increase in volume but the left speaker will decrease in volume.

Just to clarify, the center and the rear speakers are balanced. The issue only happens sometimes when I first power on the receiver I will have no center channel. If I leave everything alone for a few mins, the center channel will come on.

So it seems to me that something one the receiver is going. The question is, can anyone suggest a physical repair for the receiver for these symptoms?

Thanks

First do not panic by seeing all sockets in the back side of the receiver.You can connect 5 speakers and one subwoofer on the speaker A switch and maybe a second pair of stereo speakers on the B switch.All the speaker sockets have red and black terminals, so do all speakers. Just get decent cables ( You can buy a whole connection Kit if you want ) and connect the corresponding outlets to you speakers.If you have a powered subwoofer connect the subwoofer input to a socket labeled Subwoofer pre out on the RXV. You will need a RCA to RCA cable for that Next you will need a coaxial or Optic fiber cable to connect a DVD player digitally. The back of the DVD player will have a socket marked coaxial out, and so does the RXV's backside. Just link them .
Turn on the system everything should work. If you are not getting DVD sound there is small button on the RXV front panel called Digital input -- set it to auto ( keep pressing the button and it will scroll through various modes). Also remember to switch on speaker A on the front panel.

I have the same setup. Use 1 pair (Left/Right) RCA to RCA cable. Connect from Velodyne "Input" (left connectors) to Yamaha SubWoofer #1 Preamp output. Make sure you have the sub's volume (left knob from back) very low (full counter clockwise is "Min") until you are setting up the audio balance in your house/room. Set Low Pass cross over to 80Hz, Phase switch to 0, subsonic to 20Hz, X-over to "IN", Power to "auto"
On Yamaha RXV1 remote control, go into speaker setup and turn on Sub and any other speakers you have connected.
Warning!! do not turn up volume near a china cabinet while you are watching a movie. Everything will walk off the shelf.

hi,
u can make connections only through digital inputs(optical and coaxial). u can connect the digital outputs of ur dvd and cable set top box to the receiver. no way to connect HDMI. HDMI is a high definition media interface. for using it u have to go for a av receiver that supports HDMI.
ok

must be the right speaker wire, sounds to easy I know but maybe your wiring is grounding out the audio to that channel.

I too am experiencing this problem.... and my receiver is only 5 months old. Its a RX-V661
