• Restart your Fire TV device.

• Disconnect the Fire TV device from the HDMI port then plug it back in.
• Try replacing your HDMI cable or HDMI hub (not included) with a new one.
• Use a High-Speed HDMI cable (not included) for streaming titles in 4K Ultra HD.

• Try the Fire TV Remote Shortcuts to see if one of them will wake up your Fire TV.
