SDEC 16x2 LCD not working


I purchased the below recently.

The connections are as follow:
UNO D7 , D 6, D 5, D4, D3, D2 connected to
LCD rs , enable, D4, D5, D 6, D7 (this is not the lcd pin number)
LCD pin4 , 6 , 11, 12, 13, 14

LCD 3 connected to pot backlight, Pin 1 to 5V, Pin2 & rw (pin 5) to 0V

The site say Pin 1 to 0V but then the UNO ‘dies’ - no lights
#include <PololuHD44780.h>

PololuHD44780 lcd(7, 6, 5, 4, 3, 2);

I cant get the screen to work. Any suggestions?

Thanks in advance

I can't make head nor tail of your connections. Can you please draw (pen and paper is fine) a connection/circuit diagram clearly showing your wiring and then post a photo of it.

Thanks. I found a loose connection on my board.
