communication error.could be a loose connection from/to the display pcb.blue wiring loom going from main pcb at the side to the display gets a bad connection.usually on the display pcb end.disconnect and reconnect that loom tightening connections usually sorts issue.if it doesn't throw it away as repair cost can get expensive!!
