Same problem. I am on a Roku and every channel I select is a black screen. Tried all of the resets and authorization. No fix to the issue. Any update?
separated your off-topic post on another thread. the path must be verified as secure for HDMI. unplug and leave the roku unplugged from power and the TV for 3+ minutes. plug back in . working? if not, uninstall the channel, reinstall the channel and sign in. be careful in answering the terms and conditions.
