Problemas con Cdj 3000

Not sure what problem you are referring to. The 2nd photo shows that the player is running in emergency track mode. The USB Media or SD card lost connection or got ejected. Your 3rd photo indicates that the CDJ is not connected to the internet. The Player doesn't need to have access to the internet to operate. Therefore the last picture is not a problem indication - just shows the status.

Without more information what you did or what is not working, it is hard to help you.

What you see in the second picture happen when you got a USB selected in Player 1 and Player 1 and 2 are linked via ProDJ Link and you load a track from the USB in Player 1 into Player 2. If you now select a different USB in Player 1, Player 2 will show the exlamation mark to indicate the linked USB is gone. The loaded track will continue to play until the end as it is completely loaded into the momory of Player 2. If this happens without either eject the USB or select a different one, you may have an issue with ProDJ Link or the Network connection of both Players.
