Using an external device

Did you check the cable connected to the device?

• Reconnecting the HDMI cable

Turn off the power of the TV and external device, disconnect the HDMI cable on the back of the TV, and reconnect it.
Also, remove the HDMI cable from the external device and reconnect it, if feasible.
