I just bought a new Sony TV. It's a XBR-X43800D. The Chromecast functionality seems broken. The devices shows up as an option to cast to but when I try to cast to it from my phone it immediately disconnects or tells me "There was a problem connecting to XBR-43X800D. Any ideas? I've updated the cast receiver app on the TV and I've tried disabling and power cycling as well.
Update: I did a factory reset and casting from YouTube and Netflix now work but screen mirroring and Google Music still do not
Update 2: stopped working again
Update 3: should have probably mentioned that I have a standard Chromecast that works 100%
Next time uninstall all updates for Google cast in the system, usually gets it working for me
