hi,
An open input on pins A,B,C,D will assume a logic high, the decode for all high is BLANK led.
Connect A,B,C,D to 0V and the LED should display '0'

I don't know what connect Pin 3 to. I presume high?

I tried high (and low).... and then connected A, B and C to high in an attempt to get something to happen but nothing did.

Any ideas? (cheers for ya time btw. it is much appreciated)
