The iPad suffered a minor drop. A corner was very slightly dented. But it caused the display to show everything in an odd color palette that was heavy on reds. I thought perhaps a ribbon cable was loose.
The iOpener and kit tools were very helpful in disassembling the iPad. I had to heat some edges twice to get the glue soft enough to let go, but it just requires some patience. I saw no visual clues of damage on the interior of the device, and the cables connecting the digitizer and LCD panel were seated properly. I reassembled the iPad and it looks good as new. But when I fire it up, the display looks like a moving ocean of thin lines in a plaid pattern. Now it's completely unusable. I think the LCD panel is toast, and I have a new one on order. I'll try repairing it again.
Patience is a virtue when opening the device. Watch out for the WiFi antenna along the bottom edge. It could be easily damaged when removing the digitizer glass. Use a magnifying glass - those screws and cable connectors are really small. If you're at all handy, the device is out of warranty, and you have some instructions like what's available through IFIXIT, then don't be afraid to attempt this sort of repair.
