The display shown appears to have the wire coils type of interconnect, however any that I have taken apart has the elastomer type interconnects. I have taken them apart and cleaned the connection points, and successfully put them back together. It is important to use lint free cloths to clean as any tiny bit of lint you leave behind may result in a failed connection.

Thanks Paul. Mine are the elastomeric type. I've cleaned them but no improvement, so I assume that the display itself is damaged.
