The only thing left I can think of is that the LCD connector is internally broken. When you push the LCD in (multimeter probe), it may make contact, but as soon as the pressure is off, the PCB side and the contact open up. I have seen this once on a glass perl diode. You probe it and it looks okay, and when the probe is off, the diode is not a diode anymore. Only when I tried to de-solder it, it fell appart in pieces. From the outside this was not visible. Volhout You're telling me!!!! I really can't get my head around this one. I hear you on the LCD connector, but I have already popped off the plastic insulator to check in there, and the wee video I linked to above, has thin resistor wires inserted into the socket - which are much thinner then the LCD pin-strip pins are, and that works just fine. ...but the LCD won't. I LOVE a good mystery, but this one.....
