Be sure the system is set up properly and all connections are secure.
A connection may have come loose or may be connected incorrectly. For more info, see Setting up your product.
Check the power connections at your product and at the power source.
Be sure the power connections to your product are secure both to the AC (mains) outlet and to your product.
Be sure the power cord is connected to a working power outlet.
If the outlet is controlled by a wall switch, be sure the switch is on. You can also verify if the outlet works by connecting another electronic device, such as a lamp. If connected to a power strip (or surge protector), try bypassing the power strip and plug the power cord directly to a wall outlet.
Reset your product.
Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more info, see Resetting your product.
If powering your mixer from an L1 power stand, try a different cable or power stand.
Your mixer can be powered using an optional power supply or using the ToneMatch port on a compatible L1 power stand. If using the ToneMatch port on a power stand, try connecting with a different cable. Or, if available, try connecting to a different power stand.
Replace the power supply.
In case there is an issue with the power supply, try replacing it. If you have a safe way to test the power supply and are comfortable doing so, you can check if the power supply is supplying the voltage shown on the power supply label. It is not, replace it..
