@Elle > Sorry to hear that -- the blinking censor button indicates an abnormal power supply.
This button blinks when power input to the computer is not sufficient when using the Bus Power or any issues occurred in the USB cable. Also, the blink will continue even if you connect an AC adapter without removing the USB cable while the button is blinking due to the Bus Power issue.
Please make sure to first remove the USB cable before connecting an AC adapter to launch the unit again.
If the same issue continues even after connecting an AC adapter and launch the unit again, it may be a hardware issue. You should also troubleshoot this by switching out the USB cable or using a different USB port on your computer.
Should the problem occur again, please contact Pioneer DJ technical support in your region to have your hardware inspected and/or serviced.
