I've seen replacement screens advertised via eBay & also some HK/Chinese merchants have them. Pick a seller on ebay preferably with reliable rep-> to store, send a contact email asking for a replacement screen. Am pretty sure you'll be able to get one, if your a techy type you'll probably know how to pull the tab apart & fix the screen yourself. Good luck
Actually, I have a few epads in hand, some with good screens / non-working unit, some with cracked screens but working unit. I would be ok with selling any you need, give me a price.

Make sure that everything is compatible before committing to a dead tablet sight unseen. I have both a Pandigital and a epad. Both have 7" screens. One screen is something like 3.5 inches wide and the other is like 4 inches. (Not exact measurements.)
There are a number of "ePad" models out there, similar but actually made/assembled by different manufacturers. There is no guarantee they used the same parts.
