You may have problems with the broadcast, so you need to set up the TV first. Chromecast usually works without problems, but sometimes there may be crashes. I've had similar situations before, so I'll share my personal experience of how I fixed this issue. I usually use a special code to change the TV settings correctly. To do this, you need to know the model and number of the TV, as well as the detailed instructions that I find on the https://xtrium.com/sky-q-remote-codes/ to make it work. I've also heard that using special codes can solve a lot of problems, but I've only used it in this case.I'll let you know later what other problems can be solved using the configuration codes. I advise you to try this option, I think it will work.
