Unable to access Apple TV menu
Hello. When I switch my TV input from TV to HDMI1 the Apple logo appears on the screen but I am unable to access the Menu. When I press the Menu button nothing happens. The Apple TV light is blinking steadily about once per second.
I have tried the Restart procedure using Menu and I believe the Down button simultaneously.
Hope someone can help me with this. Not sure why it has happened as it had been working previously.
Thanks.
