But I have seen a lot older ones still doing fine. I am not familiar with this particular model, so don't shoot the messenger. The LCD have a trace circuit on the glass. The way the conduction is passed is either by a fixed flex ribbon or a conducting piece of what looks like white & black wafered rubber. The conduction of the rubber wafer can sometimes be revived by cleaning the rubber & glass LCD connections with isopropyl alcohol & cotton swabs & reassembled. To test the LCD, would require a 3vdc power source & carefully touching the traces on the glass display with the correct polarity. Check all your grounds & connections first. The Best Mike...
