That sounds like the connector to the screen itself was wiggled loose. You
may need to take the screen plastics apart to insure a good connection, but
the problem _is certainly_ in the connection or wiring. It can be fixed,
just with a little (O.K., maybe a lot of) effort.
If you need help with this, there are several knowledgeable people here who
have the web addresses and instructions you may need. I put it this way
because I'm still searching for my links and email from the crashes and
browser disappointments of 2 years ago, 1 year ago and 8 months ago. If you
need, however, I may still be able to help. Email me directly.
Sincerely yours, Grizzlygiant
