Clock does not turn on

The clock worked without problem for a long time, suddenly it hasn't turned on anymore, it doesn't show a screen, the usb connector has no power, it's totally dead. Does anyone know if this is due to something special?

@Jony Jimenez Do you have a multimeter?

@Jony Jimenez If you put your meter into AC Volts, what is the voltage coming out of the power brick?
