Touchscreen Question N800
 

First Post! Just got my 2 800's back from reboot
reloop thanks to great info on forums! One of them
came back perfect, but on one no touch screen! Is
there a software issue involved, or is it usually hard-
ware? My buttons still work, but I cant get to my
control panel or settings with the buttons, only to
small menu ie: applets,help, etc. I have tried reflashing, & lock/unlock screen to no avail. If any-
one knows how to use buttons to navigate to the
control panel or other programs, please let me know!
Any other tricks for repairing a non-responsive screen
would be awesome! Once again-Great forum-I had
given up on ever getting these to boot!
