I tested 2 other 70LB7100 units, and one had the same reproducible problem with the screen going black when selecting 'Cinema' picture mode in an app, but the other did not. All three are running the same firmware version. I also tested a 55LB6300, and that one did not have the problem.

I have a 70LB7100, and if I try to change the picture settings to 'Cinema' on any of the apps (e.g. Netflix), sometimes the display goes completely black. I can recover by powering the TV off and back on, but whenever I switch to any app after that (including some of the settings screens, e.g. naming the HDMI inputs) the screen goes black again, and I have to power off and back on to recover. When it is in this state, the HDMI inputs continue to operate normally. Also, setting 'Cinema' mode for the HDMI inputs does not appear to trigger this bug, only setting 'Cinema' mode while an app is running. Doing a 'reset to initial settings' allows me to recover, but that is painful. I also found that once it is in this state, I can recover by turning the TV off, then back on, then switching to 'store mode' (which sets the picture mode to 'Vivid') and then back to 'home mode' (which sets the picture mode back to 'Standard'). This resets the picture mode for all inputs and apps, and the apps start to work normally again. Even in 'Standard' mode I found that changing some picture settings while an app is running can trigger this bug. Does anyone else experience this?
