Blue screen on a smart controller for a rambo 1.4A board

I plugged i my board for the first time and have everything wired correctly. However the display is in solid blue. I noticed my two display wires were not working and they couldnt be plugged in the way guide said with the red stripe on the left side. I figured that my cables were one of the few that had the misprint or something of that so i went to that link and modified the cable ends for my smart controller plugged the back in and I still have the blue screen.

Not sure what you mean by modified but try them the other way, there are 4 possibilities and this is one of the wrong ones.

looks to me like you have port 2 plugged into exp 1

Ok it works now thanks for the help
