Take the contrast up to about 0.7v (vcc- 10k-contrast pin-1k0pot-0v)
that'll work usually

I've just desoldered the connector from the LCD and soldered a piece of
16-way IDC cable to the display panel. Contrast is at 0V, Vss/Vcc
connected
OK (confirmed with multimeter). Unfortunately, the only thing that seems
to
work is the backlight.
Can someone who has one of these displays please test it with my
Universal
HD44780 LCD Driver code - it's on Piclist.com under I/O > LCD >
Universal
HD44780...

Thanks.
