[SOLVED] CDJ 2000 Display Issues

Hi Folks,

Having a bizarre problem with one of my 2000's. One of my DJ's was upgrading the firmware on our machines (this might be a total coincidence), it seems that after the upgrade, one machine now is behaving badly. It powers up fine, we get the Pioneer logo screen, but afterwards, the display flashes on and off every 10 seconds or so, and in the left middle of the display a little "spinning" symbol appears with the word "waiting" right below it. It will load a cd, but not play it, and it won't recognise a jump drive plugged in to the port on top, unless I am in the firmware upgrade mode. When I enter the upgrade mode, it sees the files on the drive, I get the upgrade screen (the four file bars DO appear), but everything stays at 0%. Anyone have any ideas? I am pulling my hair out with this one (highly unusual for me, being a bench tech / soundman for 20 years). Thanks in advance for any light you might be able to shed on the subject!
