I am fairly certain you should be seeing "stuff". My gumstix water is running the same build of Angstrom as yours, and when I set LCD43 and connect everything up using my chestnut board I get the boot splash and the console shows up on the screen. One thing that might be an easy check is to make sure you have the screen connector inserted all the way into the ZIF socket. It took more "push" than I thought was needed the first time I plugged it in. Also, with lack of oscilloscope, if you have a multimeter you can use the resistance meter to measure between lines and ground... As long as it's greater than a few 100K you should be good... if you find your clock to gnd to be ~0.4 Ohms (like I did) you know there is a short somewhere. However, that fact you SHOULD see something and you don't suggests either bad lcd or Palo board. If checking that the LCD is plugged in properly does not help, I'd suggest emailing tech support at the Gumstix site and seeing about a replacement.

Hi Alex,

Thanks for your input. Can you confirm I should have seen something on
the lcd with the software in flash? Unfortunately I don't have access
to an oscilloscope to check any of those points you mentioned. I'm
also not certain I'd know a suspicious short from normal soldering.

Interestingly enough I've left my device running; about 30 minutes ago
the top 1/5 of the lcd was full of moving static. A couple minutes
later it stopped (the whole screen is just backlit now).
