So after running all day without problems it failed when you moved the
the screen and then again later again when you moved the screen.  That
is surely too much of a coincidence even if you cannot make it fail
'on demand'.  I suspect you have a bad connection.  I am assuming,
though, that the screen movements were not related to bringing it out
of suspend or screen sleep.  If you can make it fail once more
coincident with screen movement then I think you can be confident that
it is hardware.
