If your Cambridge Audio Azur 640A V2.0 amplifier is not responding to the volume buttons on the remote control, there could be a few possible causes. Here are a few things you can try:

1. Check the batteries: Make sure that the batteries in the remote control are fresh and inserted correctly.
2. Check the remote sensor: Make sure that the remote sensor on the amplifier is not blocked or covered by anything. Also, ensure that the remote sensor is pointing towards the remote control.
3. Check the remote control functions: Make sure that the remote control is in the correct mode, and that you are pressing the correct buttons for the volume control.
4. Check the connection: Make sure all the connections between the amplifier and other components are secure and tight.
5. Check the potentiometer: The potentiometer (also known as the volume control) is the component responsible for controlling the volume of the amplifier. If the potentiometer is not functioning properly, then the amplifier will not respond to the volume buttons on the remote control.
6. Contact Cambridge Audio: If you have tried all of the above steps and are still unable to get the remote control to work, contact Cambridge Audio technical support for further assistance. They will be able to provide you with additional troubleshooting steps or advice, or they may need to send a technician to repair or replace the amplifier

you have to open up the case to get to the belt and replace it.

Check your cabling. I'm willing to bet that a wire is crossed on the back your system.I've been known to accidentally swap the white and yellow components behind a TV a couple times.

Hi...

Have a tech open it and clean the laser optics and the rails that the laser assby moves on

I fix more than I can count that way

Check the internet connection. The television can't update if it can't see the internet. Resetting it breaks the previous settings. Just for fun, reboot the router as well and wait 15 minutes until all the lights come back on. Then reestablish the television connection to the router.

The most obvious reason is an overheating issue in the Power Supply board. There are other ideas here, but you need to take it to a television engineer to diagnose https://www.google.com/search?q=television+will+suddenly+turn+off+every+4+minutes ..

general steps: Get the TV remote control and push the "Menu" button and select "Options". Select "Child Lock" from the "Options" list. On some televisions, the "Child Lock" is named "V-chip". Choose the "Remove Child Lock" selection. Highlight this and then hit the "Enter" button. Enter the four-digit code that you used when you activated the child lock feature. If you cannot remember it, your only option to deactivate the child lock is to reset the TV. The instructions for resetting a TV is written on the user's manual of the TV. Exit the TV menu once you have entered the four-digit code. To do this, press the "Exit" or "Menu" button on the TV's remote control. If you don't have a remote, you might try leaving the TV unplugged overnight. Some TVs will 'forget' their settings if left without power for a long period. You could also potentially buy a cheaper universal remote, and use that to turn off the child lock.
