Now that I've tried to trouble shoot the problem, it seems that no matter what screen I put in (even working ones) only the backlight comes on and the LCD stays black. I was wondering if this could possibly be a display problem on the logic board or if it was because of the missing parts. Thank you guys!

The phone itself works because when plugged into itunes everything works, and i have switched this logic board with others and I have found the the problem is isolated with the logic board itself. Now before I attempt replacing the LCD connecting terminal, is there anything else I should consider?
