HDCP Error
I keep getting an HDCP error; I have disconnected Apple TV and reconnected and it temporarily resumes working and then goes back to issue.
Question marked as
HDCP errors can occur anywhere between the decoder (Apple TV box) and the screen (TV/monitor/projector). It can be a bad component in a device, or a loose connection, or a damaged HDMI cable.
If your TV has multiple HDMI inputs, then try switching to a different HDMI port.
