Board looks ok visually in my opinion and is the exact model or close to the one I have. I would start by plugging the power connector and connector to the display and control to your board only and powering up to see if it will read sd card (try multiple cards and make sure they are 8gb or smaller preferably 2gb formatted to FAT i believe) Then work from there adding axis control one by one. If you run into an issue then you will see that whatever has just been added is causing the problem. Look at the picture I attached below.
