First screen on my ZOOM B3 suddenly died!

Have you thought of taking the top of the case off (4 screws, from what I can tell) to see if you can spot a bad connection, or a connector off?

A long shot, but it might be worth it unless you aren't comfortable doing that. Your only recourse after that is your warranty, if it is still within that period.

EDIT: Actually, it's 6 screws - one in each corner and then one on either side of the battery case. If you do open it up, there is a small 2-wire connector to each screen that appears to supply power to that module. Check those out, if you are comfortable with that.

Look at the tiny connectors with the red/black wires.

When you pull the base off, the red/black wire connector from the battery case may pull off from the circuit board (upper right corner). Red is pin 1 and black is pin 2.
 
Tried what you said. Nothing.
Actually the screen is powered, it just shows nothing!
