Are you talking about the LCD controller cable? Looks to be orange in your picture. If so that cable is hard to work with on any of these screens, also very delicate, that's where an x-acto blade was my tool of choice, in locking and unlocking that ribbon cable holder. Its hard to seat it correctly and then lock down the holder. If its even .5mm off it will lock down but it won't work or will give erratic display. That's the part were patience is really the only way to get it.
@galvitron, I am still looking at motherboards, as I really want to use an M3 power supply but I don't think the M3 has the extra 12volt rail for processors that use it. I am going to look into it a bit more, but motherboard deliberations are still in the works.
