I can’t help you with such a small description of the problem, but I can tell you how to get the opportunity to quickly find a movie or series if you need to watch something. I usually use the application by https://showbox.zone/ This is based on torrent search and can quickly find the files you need. This will not help in the case of online news but will ease the situation until your TV works again.
You may use powerful android box and it works okay with wifi. I use such devices and have no problems.
