Mine worked out of the box even without an SD card load.  The default that shows up on the LCD screen is a console login prompt when everything is done booting.  When I loaded via SD card, I got a nice palmtop desktop.

Hi all,

 I have a  problem with my Gumstix Overo Air with Palo43 - Board:
 The LCD-Screen does not show anything, although it is properly
connected (as described in the video) and has power (backlight working)
 The touchscreen is detected during the boot sequence (see attached
boot-log).

 I am aware of the LCD - enabling procedure described in
http://www.gumstix.net/Overo/view/Overo-Setup-and-Programming/Getting-started/115.html

 (setenv defaultdisplay lcd43, saveenv) - (I did this several times  ....)

 I currently use an up-to-date palmtop image via SD card.

 Is the LC-Display supposed to work "out-of-the-box" or are there any
other (documented ?) steps necessary to set it up  ?
 is there any way to test the functionality of the display ?

what do you suggest ?

thank you,
best  regards,
Chris.
