LichessTV

No picture or sound and chat asks for FB login, how do I get it to work ??

Got a link to the page that isn't working for you?

If you're asked for a Facebook login, then that's not from Lichess...

@ProgramFOX I think he talking about twitch.tv, not lichess.org/tv
@DerekMcGill
You can re-install adobe flash player, or even the browser.

On main page left hand side the TV symbol and "Kingscrusher FIDE Titled Chess Player"

And if its "Twitch" where is link to lichess.org/tv ?

Yes, that is twitch.tv and it is not part of lichess. It is just embedded on lichess.
And the black screen is, because of flash player plugin of your browser, I assume.

You need to re-install flash player or the complete browser.(firefox or chrome).
twitch.tv/kingscrusher/profile

Thank you fiveTimes for the information, I have no interest in twitch.tv so i will not be re-installing flash player etc.

np, but off course you can watch any player's games just by clicking on tv icon on their profile, which is without commentary without any black screen.
for example
lichess.org/@/Kingscrusher-YouTube/tv
lichess.org/@/DerekMcGill/tv
lichess.org/@/opperwezen/tv
