So I used to be able to cast things (like YouTube) to our LG TV without issues. Same for screen mirroring. About two weeks or so ago I tried and just couldn’t get it to connect either way. The phone seems to be trying, but the tv never acknowledges anything. Nothing at all. The phone attempt times out.
They both work great otherwise and are both on the same WiFi network. TV AirPlay and Bluetooth are on and seem to be working from my wife’s Samsung S20. The only thing that I think has changed are Apple updates to the iPhone, but I do not know where the problem exists.
Any help in resolving this would be appreciated.
Try doing a soft reset by pressing volume up then volume down and then holding the power key till you see the Apple logo at which time you can let go off the power button.
