A DJ friend yesterday inserted his SD Card into my CDJ-2000 Limited Edition (non Nexus) while it was playing a track and upon inserting, the screen, loop buttons, cue & play buttons all went out. Now when I power back on the CDJ, the only things that come on are the track search and search buttons and the light for where you insert a CD. No other buttons light up and the screen is completely blacked out/blank. it doesn't even load the pioneer logo, but during powering on, you can hear the CDJ make that loading sound it makes when you power them on.
I have tried doing a factory reset (usb stop+disc eject+power button), as well as tried doing a firmware upgrade (usb stop+reloop/exit+power button) and still nothing.
Its as if the SD Card short circuited something, but my DJ friend said he had used the same SD card the night before at a gig using CDJ's. Any help or input would be greatly appreciated!!
