The video was not displaying but everything else seemed to work ok (syncing). $349 for a "fix" (actually, a new iPad) from Apple seemed to expensive. We *love* our iPad .. and would like it healthy again.
Separated the screen from the shell - broke all the clips except one. Confirmed the video cable had come loose. Found iFixit and ordered the parts and tools. Super fast delivery and then ... voila ... a working iPad again.
Don't drop your iPad. Doh! ... but if you do, look for iFixit to help!
