Imonitor X30 has stopped seeing the receiver . In the light bar at top of screen, the middle led is lite blue constant all the others are off . I have reloaded software and power firmware. receiver and wiring looms all good (system works with another x30) still no pickup of the receiver . I know its communicating with receiver as it sends the receiver into fx mode as soon as plug in faulty x30 . Has anyone had this before or got any suggestions ?
