I received my X5 Mini with the screw type terminals. Now all I get when I turn on the printer is a blue type of screen with no text on my Viki LCD.
Got any ideas where I might be going wrong? The SD card has two files on it. The config.txt and FIRMEWARE.CUR.

All of the LED’s 1-4 and lit up including the LED by the INT/USB jumper.
Mine did this when I first hooked everything up. The only problem I could find was that my endstop wires were switched and connected to the wrong terminals.
I removed the endstop wires entirely and still just have the blue screen. I also unplugged all the stepper motors cables from motors themselves, but still no go.
Do they need to all be connected? I don’t know, just taking a stab in the dark.
I guess I must have deleted the firmware file off the sd card at some point. It’s working now that I added the firmware back onto the sd card.
Mira primero si la tarjeta la lee la x5, y si el archivo Config está bien configurado para tu lcd
