i2c 16x2 rgb lcd pi plate no backlight
I just put together the i2c pi plate and 16x2 blue/white character lcd, and I'm getting no backlight. I have checked ALL my solder connections, and my Pi will light an LED with 5v. I can see the boxes on the first row because I haven't served it anything to display yet, and I can adjust the contrast, but the backlight fails to light. Is there something i'm missing?
