Broken volume control knob - Sony STR-DB1070 Receiver

The volume control and the volume knob are broken and worn out and will need to be replaced.

The volume control knob PROBABLY is broken, dirty or has bad soldering to the circuitry.

Use some CRC226 in the control if dirty. While you have the unit apart, check the soldering and for any circuit board cracks.

Looks like you have several faults?
First try to fix the remote:

The flex that controls the volume on it is broken it is a strip that has wires to it.

It sounds like the volume control pod has gone bad and needs replaced (The knob shaft connects to the pod main body and the inside of the volume pod is what controls the rate of volume,If the inside becomes worn ,broken or dirty the volume will become erratic) Replace volume pod ! ..You may try cleaning by taking off the volume knob and getting a can of pressure air and blowing the dust out!
Please rate response!!

I located the remote control for the unit and it works fine. As the unit is not the primary amplifier for the home stereo system, I use the remote to control the volume. Thank you for your quick responce, and I will keep you in mind for any future needs.

The simplest thing to try is some compressed air directed to the knob. This would clear out any dust or dirt that may be obstructing the knob. I am not sure what you mean by power cut so I am shooting in the dark here. If you mean a power surge that caused the volume to quit working then I would suggest an external volume control such as http://www.amazon.com/Koss-155954-VC20-Volume-Control/dp/B00001P4XH/ref=pd_bbs_2/002-2257004-6895258?ie=UTF8&s=electronics&qid=1194009359&sr=8-2

Windows has a volume control built in, look at: control panel, sound and audio devices, volume control slider and check box for "place volume icon in task bar.

Hi Your Problem need an expert Technician, this Aiwa stereo has the digital type volume control that gives pulses to the cpu to make volume up / Down. Solution to be fixed by a technician: - Remove the volume from the front board, disassemble it and clean the conductive parts inside it then reassemble back and check. Good Luck Toufic G. Malek
