My Lightning adaptor will not play video on my tv only audio it worked fine 1 week ago I purchased a new adapter today and hdmi cable it still won’t work on 3 different tvs

If you haven't done do already, you could try updating to the latest iOS version: 16.3.1 at the time of writing. Several people have reported this issue being solved by doing that.

Ps: it also helps to use an authentic Apple HDMI adaptor rather than the third-party ones that seem always problematic.

I'm very pleased to hear that the advice was useful. Third-party HDMI adaptors are notoriously unpredictable. It might be worth contacting the developers of the sports app. I hope you get it to work. Thanks for posting back.
