Factory reset sony mhc-6700

I don't think that will cure the problem. Volume controls these days are done by an IC. If it fails it can cause the volume to go up on one channel and not on the other. If you trace the wiring back from the volume control you will eventually run into the chip. I would have thought that the two channels will go into one chip and not two separate chips for each channel, but it depends on how complex the system is. If you are lucky the PCB will even tell you that the area is tone and volume control.

Why does the volume increase when I'm trying to turn it down on my AIWA receiver?

Your volume control is bad. If you are good at this kind of stuff, you can remove it from the board, open it up and clean the contacts. Otherwise you need to get it replaced.

Sticky volume control when turning up and down

The volume control needs a good flush out, take the unit apart to expose volume control pod, buy some electronic contact cleaner and flush the pod while turning the volume back and forth, repeat 2 or 3 times. Note some pods have small slot where you can spray.

Volume goes all the way up by itself

1. The volume up button on the remote may be stuck down- try wiggling the button to get it out. If it isn't the remote if the local volume control is in fact two buttons perhaps that one is stuck in or damaged.

2. The dvd sounds like it needs a new laser unit- a worn laser unit may play up like this.
It might be time for a new one as replacement can be sometimes more than the cost of a new one nowdays!

the volume control needs to be cleaned. this control is a step switch basicly. and the switch contacts are not making proper contact. cleaning this requires dis-assembly and desoldering so if you are inclined to do this work happy fixing if not it shouldn't cost much to fix.

Volume knob

Normal Aiwa compact shelf units use what is called a jog switch for the volume. Usually you can tell the difference if when you you turn the volume up or down. It goes a short distance and seems to spring back. In this case there are two momentary contact switches. One for up one for down. With a plastic lever on the back of the knob that bumps the approriate switch whether turning down or up. If the lever is broken it will bump up against one but not the other. If it is broken plastic you know how good gluing plastic goes it never seems to hold.
