Thanks for getting back to me.
I can see that you spoke to one of the team previously so were you able to check if there were any firmware updates on your smart TV?
There is a known issue with the V6 displaying a green screen but this should only be happening if 1080i is enabled.
Is it still a green screen for Netflix and a black screen for YouTube?
I'll look into this to see if there's another work around until a firmware update has been released.
Thank you for your patience so far.
