ProfBob: No Backlite boost voltage. Just received the board today and have the same problem as Ken-Hack. You can barely see the Sparkfun Logo. I checked the the voltage boost out at C3 on the schematic and it is 5V and not 7V as stated. The resistors next to C3 should be R1 = 3.3K and R2 = 15K, both on my board are 3.3K<br />
Can anyone verify the resistor values on a “working” board. Thanks<br /><br />
I got it working. You need to make a dirty hack to it, but it works. I wrote about it on my blog. Check it out: http://richardkaufman.org/blog/how-to-fix-it-backlight-on-sparkfuns-color-lcd-shield-not-working
