I'm trying to remove the Instrument Panel circuit board so I can repair the tach (high resistor value).
I carefully pulled up and removed the gauge connectors, but I'm stuck at trying to remove the connector from the LCD (it's the only thing holding the circuit board to the cluster). There are wires (not pins) under the connector, so I assume I should pull the white connector loose from the circuit board (arrow)

But, I can't get it to come loose and I don't want to apply too much pressure.
So, how do I get this connector off?
TIA,
Gary
