I tried to Re Install from the app - but i still have a black screen.
Can you please advise the correct steps for this HotFix ?
You shouldn't need to reinstall, the app should update itself to the version (1.12) with the hotfix. If it hasn't already updated, try rebooting the TV at the wall (unplug from power and leave for 10mins before turning it back on).
Still a black screen for me too, I turned it off at the wall for over 20 mins and it’s exactly the same, when you just have a black screen it’s impossible to look at any settings, assuming for us at home there even is an ability to look at any.
