A: 1.Check the hosts turn-on status, if only a blue light on, it means the host is in standby status and has not been started up yet, meanwhile check whether the hosts power cords red & yellow cords are in power supply status or not, if only one cord is supplying power, the device is unable to start up. 2.Check the power supply status of display screen, as well as check whether the display video has been switched to AV status. 3 Check the connecting status between the hosts video output cable and display screen. 4 check whether the lock status of the hosts LOCK, it mu
