I tried switching my 2015 KD-43X8309C on via the Netflix button, and got the initial message from the TV, but instead of Netflix, I just got a black screen.
Checking round, everything else seemed to work - live TV, apps, menus, etc. - except Netflix, which just kept giving a black screen.
I gave the set the five-second reset from the On/Standby button of the remote, and when it came back, Netflix was fine, accessed conventionally.
And this morning, all was OK even when i starred the TV with the Netflix button, which started it up and went into the familiar Netflix screen with no issues.
