Really great site!! replaced a LB in an mid 2010 MBP with kernal panic crash. Fixed! No issues with detailed procedure and comments. So I'll add one for this step. This was the simplest step really. Additional clues. (Wish I could post a pix). Look at the gold conn in the pix above. Note that the cable mates with the conn with the 2 tabs each side showing full insertion. The silver retainer pops up, bar away from the cable. Using my custom tool, a small screw driver, filed really small as I don't have a #000 Phillips, release the retainer, then carefully wedge open the tab on each side, inserting your "tool" in the slot. Neatly and slowly, the conn comes apart. Putting it back together, once the conn is alligned, just push alternately on each tab. Doesn't take much effort, better that pushing on the cable. I also appreciate the comment that removing the clamp, both clamps with one screw actually, makes this easier.
