Success!!

You need a steady, fairly hard, downward pressure on the PCB as you tighten the twist tabs to insure a good contact between PCB pads and their contacts below. Keep the little tab wings pointed down, not folded up.

You probably have another three or four tries before the twist tabs break, so give it another try Smile

Thanks for the encouragement. I removed the PCB again (4th time now), and examined the rubber contact strip under a magnifier. I found some dust, so I carefully cleaned the strip and PCB contacts with a lintless "pec-pad" and methanol based cleaning solution (digital camera sensor cleaner), and reassembled once again after straightening the pins on the twist tabs.

Keyboard and display are now back to normal.

I popped the bottom "rivets" back in and they feel pretty solid, but the top rivets, having had their tops drilled out, leave the case feeling loose. Is there a recommended method for reattaching them? I'm thinking a small drop of epoxy in a couple of them would work.

Thanks!
