XDJ RX OFF ALONE

Tonight for the first time the controller get off alone and only the red light of the recording next to the usb 2 was flashing.

I took out elecrticity cable and the light was flashing for 30 seconds more.

Than after 5 minutes i put again inside the cable of elecricity and normally was on BUT after 10 minutes did the same problem again off all and just this small red light was flashing.

the firmware is the 1.8.
