Mike. I don't think a business card will do the trick.
There are a few cables that connect the screen components and the main board.
It's more than possible that one of them became disconnected during the fall.
There are (that I know of) two good resources for taking apart your pda.
1. a pictorial examination to take a pda apart. I think the site is x51v.it . Or something like that. Maybe someone else can chime in because it is a good resource.
2. See this mobility site post for a video presentation to identify the cables and help you put them back together. It is easier than you think.:

If none of this works, then the curtain fell and the show is over.
