Volume goes up and down by itself


Hi wally,

It is sad your having a problem with volume automatically increases

and decreases without any manual input.


These could be caused either by a component on the circuits

( front panel), a faulty regulator or microprocessor.

Components :

can be such as tact switches , diodes

PCB foil tracks, connectors. These means it may needs servicing.


Start with the basics, take out batteries from the remote, and see

if it affects the receiver volume or the one causing the problem.


If the symptoms still persist, One may have to open it up.

and check on it.Have a tech to guide you if you feel you can DIY.


One of the ways to tackle these problem is to take out the

tact switches , or have it disconnected . And use the remote

volume control to adjust the main volume.

If these works for a day or two, find or order replacements

for the said bad components.


There might be other ways but that is what Tech are for.


Let us know what you find , or needs further assistance.

Extended power loss might lose memorized settings. Pretend the unit is brand new and verify all of them. No video from CD??? Really? Good luck with that.

Systom shuts down when volume is adjusted


These systems have a "power overload" protection circuit. When there is a short, or any defect that causes the unit to draw more current, it will shut down at the source of the power. The problem can be as simple as shorted speaker wires, but it can also be any number of shorted transistors or components in the amplifier stages, hence servicing is required, in those cases. Often, it's the final output power transistors, and you might get lucky and be able to find a replacement if you can identify it with a voltmeter. Other than that, it's the decision to have it serviced or not. Get an estimate, service usually isn't cheap.

Broken volume knob


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.

Static while adjusting volume on Cambridge SoundWorks model twelve


If the volume is controlled with a mechanical volume control, usually a knob you turn or a slider you move, the problem is the volume control device (potentiameter) needs to be cleaned. That requires special cleaning chemicals most people do not have in their home. You would need to take it in to be serviced. This is a very inexpensive repair. Normally only costing about $50 to $75.

If it has electronic controlled volume like a button you press then it will still need to be serviced, but this is an unlikely case with static in volume when using the volume control.

If I can be more help let me know.

Volume control unstable


You may have an over heating problem as it the Integra has anautomatic cut out. The unit generates a huge amount of heat and needs to be positioned in a very well ventilated position.
