WP 34S will not turn on

[brettpim]

I have tried that but it has not helped. On page 148 of the 3.1 manual it says that the ON button "shall turn it on, as long as the batteries are good – even if you do not see anything on the LCD." If it is indeed turning on, what could cause the LCD to not show anything if it has simply been sitting in a drawer in its case?
