Question about Yamaha RX-V863 Receiver

Open Question

My centre channel keeps dropping in sound volume intermittantly on my RX V863 Amp. Not a loose lead or component issue as far as I can tell. Volume level will drop by 75% and sounds like it is well back in the overall sound mix. This will happen when using SKY, DVD and PS3

SOURCE: volume level dropping unexpectadly

The A1 has an internal self diagnostic program which you can go through to find the fault. You can access the diagnostic program by simultaneously pushing some buttons on the front panel. The Yamaha service manual for the A1 tells how to do it and what the diagnostic codes mean. You can get a copy of the service manual on the web from several suppliers for a small fee.

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

Do you have all 5+1 speakers connected? You need to go to the Setup menu of yamaha and set which speakers you have and which you don't. For example if you don't have the Center speaker connected, receiver will redirect and mix the sound to the other speakers.
Blue-ray film over HDMI should automatically output via all your configured speakers (nothing to be configured).

My Fender Hot Rod deluxe makes a popping noise when switching back to the clean channel.


This is because your clean channel only runs through the pre-amp section, requiring an increased volume level to match that of the volume of the drive section which is overdriven by the pre-amp circuit. my suggestion is to use lower volume level on the clean channel of the amp. To get any volume boost you may need to match the two channels you could use a signal/volume booster or overdrive pedal between your guitar and amp input, switching it off and back on when you switch back and forth between channels.

Yamaha RX-797 shuts down when playing at low volume while increasing the volume. If you lower the input wolume from the source into the reciver you can increase the volume on the reciver but when you reach...


That would be consistent with reaching an overload threshold on the amplifier's outputs.

This is mostly boilerplate but it may lead you to the problem...

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Whenever I slightly adjust the "Channel Volume"


You've got a loose wire! What's happening is that there's a bad potentiometer (the electrical component behind the knob) that's out of place and is only connecting fully at one point in the knobs circuit (the part where you get full volume) take it in to an amp tech at your local music store and they'll fix it up easily.

My harmon kardon av amp keeps losing its memory/settings when its switched off, it also loses audio on the 3/2/1 on the aux, dvd channel, intermittent loss of volume help, too good a system to bin thanks


could be the memory chip, I used to see this a lot with Panasonic tv's that would lose all memory settings ie channel and tuning memory, with the intermittent vol problem it sounds like dry joints in the amp section, always check the components around the heatsinks for dry joints, especially capacitors and transisters, pay to get your hands on a service manual showing all the layout and different componets.

NAD 7020e sudden volume drops, sudden distortion- intemittently


OK. I dont know the answer to your prob, but to let you konw that youre not in this alone, my amp used to occasionly lose considerable volume in one channel. this could be remedied by cracking the volume up to max for a half second or so. (Not a great solution!!) It has finally given up the ghost ...I have lost one channel and the doctor says it wont come back. Not only this but they claim that spares ceased to be sold back in the 90's. having said this I have enjoyed this amp for almost 20 years. I think its time to put it to pasture.

putting the extra speakers on wont solve the problem the unit has a max output it might give a better alround sound so it will be clearer a little but pushing to far on standard speakers wont help if you need better go for some active speakers there more exspensive but will give better definition and the volume limit might be higher.
