I too have this problem. However You can buy used View Tablets on Ebay for approx. £250.
I'm sure any repair would also be in this region so it's worth a cheap replacement.
It's a difficult size screen to protect, particularly if your a gigging musician like me. I have found that the official padded case from amazon at about £45 takes a month to deliver for another £10.
I am pleased to continue talking if anyone has any useful ideas.
