There are several potential causes of interference hum on a Yamaha DGX 670 keyboard, such as grounding issues, electrical interference, or faulty components.

To diagnose and repair the issue, you will need to open the keyboard and inspect the power supply, grounding, and related components. It is recommended to refer to the manual for your keyboard or contact Yamaha customer support for detailed instructions on how to access the internal components.

If you are not comfortable with performing electronic repairs, it is recommended to consult a qualified technician or engineer for assistance. They will be able to diagnose the issue and provide the appropriate repair or replacement of the faulty components, including the power supply and grounding.

Additionally, you can try to reduce the interference hum by moving the keyboard away from sources of electrical interference, such as power cables, fluorescent lights, and electronic devices. You can also try to use a power conditioner or surge protector to filter out the interference.
