I have this issue where a black box comes down from the top of the screen often. Some times it happens every few seconds several times in a row. I suspect that it is a notification box which is missing the text. But I have no idea why it is happening.
I tried disconnecting the HDMI device and it still happens.
I tried shutting down my AllShare server on the network, and it still happens.
I tried removing my Samsung account from the TV in case it was the cause, and it still happens.
I think the issue only started after I updated the firmware to version 111. ( I think it was the last digit of the version, I will check again when I get home to get the full version).
The issue happens while using HDMI.
Happens while using the YouTube 'SmartTV' 'app' (its really just a web page).
It even happens while the Smart Hub is up.
I still have to try resetting all settings on the TV and see if that helps.
I have not been able to find a way to revert the firmware, but I would try that for sure.

TV model: UN46F6300AFXZC
Specs: Samsung 46" 1080p 120Hz LED Smart TV
No replies at all, eh?
Let me know if you have any other ideas of things to try. Looks like rolling back to an older firmware is 'not possible'. I really think that firmware 100 (the one it shipped with) did not have the issue.
I contacted Samsung support... they said 'it may be in 'Demo Mode'. They were wrong and it is already in Home Mode.
I contracted them again, they said to do a reset to factory defaults. That did not help either.
I just contacted them again. I provided more videos of the issue, including while using the out of the box Setup, Smart Hub and while watching static with no inputs connected.
I am tempted to just take the TV back, but no Futureshop or Best Buy stock this model so getting a replacement would suck or I have to get a different model.
If factory reset didn't fix it I'd swap that set out.
