If your display is showing a flashing screen, start by restarting the devices that are displaying the black screen.
External Devices
For external devices, unplug the power supply, then plug it back in. The player should reboot automatically.
Samsung or LG Devices
For displays with built-in players, use the Samsung or LG remote to power the screen off, then back on again.
Check Connected HDMI Cables
If using an external device, check that the HDMI cable is securely connected, or the display input is incorrect. Try switching the display input (HDMI 1, HDMI 2, etc).
