One display works but is very faint. I read more here, and increased the contrast to 70% - that display is now fine.
The other display worked (faintly) initially, got more and more faint, and now now longer works at all. (White LEDs ok, picture is blank.)
I'll post pics tomorrow - I left my handy picture taking device at home.
