Try this
- Switch the TV to its own Home screen, not an HDMI input or a screensaver.
- In Kliky, pick the TV again.
- Watch the top of the TV screen: the prompt can disappear after a few seconds.
If the TV has stopped asking
- Samsung: Settings › General › External Device Manager › Device Connection Manager › Device List. Remove your phone, or set Access Notification to First Time Only.
- LG: turn on LG Connect Apps (older webOS) under Network settings.
- Fire TV, Google TV: restart the device by unplugging it, then connect again.
TV still on its first setup screen
A TV that has not finished setup cannot pair with a phone. Finish setup with a remote, the TV buttons or a USB keyboard first.
