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

 I am aware of the LCD - enabling procedure described in

 (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,
