Sx2 just stopped

Hi, I've had my sx2 for a few months now and all was working fine but it has suddenly stopped. Start serato turn on the sx2 and all lights flash like their ment to. The hardware bar thing on the right goes. Then the screen flicks onto the decks and then just goes back to the normal screen. Since this I've updated the drivers which were up to date anyway. I've done the firmware which again was up to date. Updated serato and still nothing.
Please can anyone help
Thank You
