Sony Bravia TV "Cast to Device" function not working

[Leonell12]

Hi all, So I have a Sony Bravia kd-55x8509c 4k tv. It's running Sony's android OS and is updated to the latest firmware. Now, the tv has a "cast to device" function where other devices like my windows laptop can play video/ audio directly on to the tv if both are connected to the same network (our home broadband). So, if I have a video (default player VLC media player) on a windows 10 laptop, right clicking on it gives me an option to "cast to device", wait a few seconds and the tv (provided that it's already on and not on standby) then automatically plays that particular video. This has been working fine, however, it has now stopped working, for whatever reason. Clicking "cast to device" now does not work. The tv says it is "loading" and then says that it "cannot play video", following which my laptop is disconnected from the internet and will only connect back to it after a restart. Any ideas? I will provide images etc. of what pops up if needed. Oh, and as a side note, I don't know if the TV uses bluetooth for this to work or an internet connection, and when i bought the tv i did not go through any setups on my windows laptop to get this to work, I just sort of accidentally stumbled upon it and thought it was a cool feature.

thanks

its probably through wifi not bluetooth

i can do it to my lg tv with windows 10 cast to

but lg have their own software which seems to work better/more reliably

look to see if sony do too

edit--shouldnt even need to play the video in vlc and use its option--should just be able to right click video file and use windows built in cast to

and obviously if you pick a video in a format your tv cant support it wont work

Well I never open the video in VLC or anything. I just right click on the video file itself, and as far as the format is concerned, I've tried it with videos that worked before, but have now stopped working, with the same format (mp4).

Well there are a few apps on the TV itself but all of them are for mobile devices/ tablets and not a windows computer. I don't really know what I can do about Windows updating itself, if that's the cause. I will try, however, using another computer and seeing what happens.

the app goes on your phone or on the pc--not on the tv--i dont need an app on the tv to receive i just go to lg software on pc or my phone and send music/video/photos

look on sony web site to see if they have one the same idea

Nope Sony has no such thing that I could find.

That only works with Phones or tablets that support Miracast, If I go into the "How to set up your device" option in the app, it shows instructions for mobile devices not computers. The "Cast to Device" function used to work before but stopped suddenly, I would rather have that back if it can be fixed.
