Check your "A/B" speaker selector switch on the front panel of the receiver, if they are on, you will see "A" "B" or"AB" on the front display. If they are on, You need to have the receiver serviced. Just a note, Yamaha's rarely have an output problem! Hope this helps
Officially this receiver supports only 6 and 8 ohm speakers. But for surround speakers it should not do any harm, because they are not played at full volume. But be sure to set yamaha for 6 ohm speakers. Using only 4 ohm speakers makes the amplifier work more hard and produce more heat, that's why you can't use it at high volume.
If the positive wire is touching the ground wire anywhere in your system, this will occur.
Run the speaker "test" to hear all speakers. If one does not sound off, that is probably your shorted wire our bad speaker. Check for a bad splice, back of receiver speaker output, speaker input, or wire shorted on tack strip under carpet,etc.
If this does not help, you may have a shorted speaker channel in the receiver itself.
This goes for most all receivers that are not vintage in age.
Sorry to have to tell you but that means there is a short in the output circuit or the power supply. I would bet that one or more of the output componets are bad. If you know solid state circuit troubleshooting, It still may be worth repairing. if you do not then most likly it is time to get a new unit.
