I have had a Pioneer VSX-D608 for 8 years and have had very little problems. I usually keep the volume level around -35 to -40, but all of a sudden I have an issue. The other day, the volume wasn't working correctly and it no matter how much I turned the volume nob, it wouldn't change from in the -80's.
I partially answered my own question...the remote is working fine. How do you fix a volume knob.
I just picked up one at the dump. You have to take apart the front end by unscrewing screws and pulling out ribbon edge connections. It is easier than some components. Then pry off two of the small clamp downs on the front of the volume potentiometer; pry apart about 1/32 of an inch and spray control cleaner for a second and clamp down. repeat on other side.
worked for me.

Re: D608 - Volume Problems
I've seen similar problems with volume knobs on older stereos in cars, and it should be the same with home stereos. What happens is the knob itself starts to come unsoldered or lose contact somehow from the main board in one or more of the multiple connectors. I recommend you open it up to have a look at the knob's connection to the main board, and see if any of the connectors have lost contact. If they have, the best you can do is to resolder them.
Either that, or get used to blasting music :)

I am trying to work out which has got the high volume.
If it is the Pioneer then it could be the volume control chip that is faulty. These days volume is no longer determined by a control that adjusts the signal level. The signal is passed to a chip and the volume control setting information is also passed to the same chip. If the chip goes faulty then the volume will sometimes go to max, regardless of the volume control setting. This can also apply to the TV sound as well.
If the sound level is high on other functions of the receiver, such as the radio, then it is certain to be the sound volume control IC.
You are doing nothing wrong at all. It's just that as you say it has no phono input. Which means the sockets you have will NOT amplify the signal. So you need to buy a magnetic cartridge pre-amp and once connected to the aux the weak signal will be at the normal level.
Have you tried changing the Auto Standby switch to ON?
You can prove if the sub amp will respond to a known good input by TURNING ITS VOLUME DOWN tp start and just feeding it ANY RCA output from the receiver while playing, say, FM (to keep it simple). That way you would known in which direction the problem actually lies (internal or external).
Aside from any intrinsic problem with your receiver, the usual suspects are;
1) Poor receiver ventilation.
2) Very high levels of bass.
3) Shorts in the speaker wiring.
4) A rubbing loudspeaker voice coil.
No, this sounds like a speaker problem to me.
It sounds like the voice coils in your speaker(s) have been fried.
What happens is the part that is burnt does not funtion, but as you increase the volume/voltage the speaker "jumps" foward to a section of voice coil that is not as damaged.
Check your speakers!
Your receiver is basically going into protect mode.
Just check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Take out all the wire and put them back again if necessary.. Some times even a little tiny frayed wire touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit. Just check your speaker as well....whether they play all right thru another receiver or amplifier. its posiible they might be shorting inside. A little frayed wire could also trigger the protect circuit in your receiver. I hope this should solve your problem.
If everything else seems all right and still your receiver shut down when you raise the volume then it possible that there are bad connections on the main board that are set in.
This would generally happen if the system is slighly old or have dry solder and when you raise up the volume. This should be a simple repair that will not require parts. If you can solder, you will be able to repair this yourself. If not, then a local service center will change the local labor rate.
Hope you can sort out your problem with the above trouble shooting. Let me know if I can guide you further. Best of luck! Thanks for using FixYa!
