CDJ 2000 crash red jog wheel burst (look like), still playing. no faultcode

Dear dj's

last Friday i was playing via link some songs from another cdj's usb devise. and suddenly the cdj screen went down and the jog wheel became red flashing. after some second the screen came back and the jog wheel went white. 

all the buttons around the screen were off and after a while when pushed they light up.

Hot cue A became green and Hot cue C became orange. B was off. (pushing it doesn't do anything.)

in the center of the jog wheel you see something like an burst projected. this says for me that the software recognized an error.

the tracks never stoped playing. after an software re-update i couldn't reproduce the fault. 

does anyone recognise this fault? i don't trust this machine anymore.

(oh, and ance an full glass of vodka redbull run over the player. the player has been cleaned after this but it can be the reason. but what part do i have to replace with this fault?)
