Yep ran it with my HC.
I have a HC diagram. So far:
Pretty much is 5.4V is present, the LED is on.
If the +5V was not present (pin 1, J1)then the display IC's would not be buffered with data (from the controller), it would lock up or disappear.
The keypad has a PIC micro controller that reads key presses and this uses +5V as well.
All in all looks like a bad HC cable or +5V is not going to all the appropriate places in the HC. My bet is cable. If the membrane was bad then some buttons would work and some not.
