try resetting connectors maybe?? there could be just a bad contact
try both .. the connector between the boards .. and also the flat band cable (loosen clamp on the flatband .. pull out, reseat and tighten clamp)
also a cold solder joint may cause such things (inspect solder spots around the flat cable)
good luck
