My Nikon D5000 camera's LCD was cracked (and probably leaking) so i ordered a spare part to fix it since i dont want to spend too much sending it to a repair service with on a tight budget. Anyway I wanted to ask when i opened the body i found there was 4 different type of wire Orange, Blue, Black and Red. The Black and Red ( I might know , correct me if im wrong) are the power supplied to the circuit board LCD and the other 2 wires is an orange and blue wire that's not connected when I open the cover. Also, when I successfully assemble the new LCD the screen cannot rotate normally unless I open the cover . Can one of you guys please explain to me, cuz im a bit noobish here

Here are pics to show you
