I'm very sorry to hear that has happened, and I apologize for any inconvenience this may have caused you. In order for me to help you most accurately, please provide the complete model code for this device.
The new updated just installed.
This is so sad its almost comical. Example - run SmartHub, open Samsung App Store. Hit return button to return to SmartHub. SmartHub flickers and changes shades as it momentarily changes to several different TV Modes, and then.......black screen.
Will this ever be fixed? This is a new 2012 high end TV...
