No success here. I could not figure out how the black retainer worked in order to release the ribbon cable for the display. I ended up breaking it. I tried to put it back together anyway to see if there was sufficient contact to make it work, but evidently not. Oh well, a $50 lesson. One other tool that is needed here is a jeweler's magnifying glass. Magnified pics in these instructions would also be a benefit. Also, can someone tell me how you're supposed to get that one recessed screw back in place?
