The Fire TV and Fire TV Stick will check that your television is an authorized HDCP compliant device before sending the video signal over the HDMI cable.With software updates 126.96.36.199 and 188.8.131.52 for the Stick, it appears that Fire TV devices have changed when they enable HDCP encryption of the video signal.
One is inconvenient, while the other requires spending money to fix a problem that shouldn’t be there in the first place.
When upgrading to firmware version, many users have found their i Phone, i Pad, or i Pod Touch will not boot past the White Apple logo screen.
Other users may have done nothing and also find that their device is stuck in limbo and won’t boot.
You can do this even if you are looking at a blank black screen.
An alternate solution to bypass this issue all together is to place an HDMI splitter in between the Fire TV and your television.
