Q: Screen replacement

Apr 12, 2012 3:23 PMby Ronda Wilson,I'm wondering whether the display, itself, is compatible, since the inverter cable isn't.
The inverter cable can be found here:

I can operate the computer, move the mouse, select menu items, and so on, but there is no backlighting. I checked the signals on the 4 pin connector on the motherboard, there's a ground, a +5 V and two 3 or 4 V signals, probably controls. I just don't know which signals should go to the 6 wire cable. Unfortunately, standard colors don't seem to apply here, the red wire on the 4 wire cable is ground and the black wire is 3 V, go figure. I could just use trial and error and hope I don't blow something out.
Thanks, I'll check out the ifixit site when it comes back up.
