DDJ SX NO POWER, cue and play working but no music

I bought a DDJ SX a few years back and used it for a few events. I went to a christmas party and suddenly it didnt want to power up. i bought a new power supply for ddj sx on amazon but it still doesnt power up.

Help Please

if ever sent for repair how long will it take until it will be fixed. i have a few bookings this january and have nothing to use.
