The chip works on the board.
The LCD works on another board.
You can drive LEDs via resistors from the connector.
A display won't work when plugged into the connector.
It seems to me that the most likely the problem would be the connection between the connector and the LCD plug.
You say that you have taken off the plastic shell of the connector and it looks OK but I would still replace it just to be sure. I can't think of anything else. The resistor leads may be making a different contact point.
