I have a Yamaha RX-V793 that has stopped working. It powers up but I can not get any sound out of it on any devices. The red LED on the volume control keeps blinking now just it did not do before. Acting like waiting for program command. I can get the volume nob move by remote but not sound. Appreciate any help. Scott

There is normally a capacitor on the back of the display that may fail. They normally get dimmer until you can't see anything. Replacing it should fix it.

You need to check the settings and also check the connection from receiver to five speakers .

(1)read P.10-11
(2)follow the instruction to perform self diag test
(3)or check DIR & DSP with an oscilloscope.

If the channel is dead on headphones suspect a fault in that channel. The good news is that you have the good channel to compare it with. Since the channel parts are identical. You can start with a visual check. Looking at the good and compare with the bad. Any bad looking parts should be replaced. If you are experienced with electronics you can do tests on the channel. Otherwise it is off to a repair shop with it.

You have a bad Rotary Encoder(what you think of as a volume control) It is not a variable resistor, as in decades past. It is an input to a microprocessor(a computer within your Yamaha). If you require additional assistance, or would like to inquire about repairing your Yamaha, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

My first thought would be that when you moved the receiver to connect another DVD, the problem quit since the speaker wires moved. The best way to test would be to re connect the original unit the same way as the new unit and test again. If it still cuts out, disconnect the speaker wires and re test. if it still cuts out, try the new player and test again. if it does not cut out, there may be a problem with the old units audio output. Generally if its a problem with the receiver it would not matter what source you are using, even the tuner on the receiver, if there was a short in the receiver it would cut out. Let me know what your results are and I will help more if needed. Best of luck!

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.

But does the unit power up? Or is the unit working?

I have the same problem, I'm thinking that the equipment is old and I need a new one. need an answer too!!!!

Per Yamaha support page: The volume light on my Yamaha AV receiver is flashing, what does this mean ? The "MUTE" function on your remote control has been activated. The reason that you can still hear a very low sound is that the muting circuit within your stereo is not a full mute, but rather a -20dB mute. To deactivate the "MUTE" function, simply press the "MUTE" button on your remote control. (Make sure the volume control is turned down to avoid damage to your system.) If you misplace or lose your remote control, you will have to purchase a new remote control unit, as there is no duplicate function on the front panel of your stereo. Unplugging the stereo will not deactivate the muting circuit, as the microprocessor "remembers" if the muting circuit was active prior to being turned off or unplugged. If you need to purchase a remote control, you may order one directly from our parts office. You may reach them by dialing (714) 522-9888 from 8 am to 3 p.m. Pacific Time, Monday through Friday.
