Smeeth,
I read your post last night and thought wow, it sucks that you are having problems when you just got your new CS UB. I felt very lucky because I also just received my new CS UB (from B&H) just yesterday and tested it that same evening with no problems.
Well, I'm sorry to report that all that has changed. Like you, after having run the display for about an hour this morning, the display started flickering very rapidly for a very brief period (about 5 seconds) and then the screen went dark. I can still see something (like a screen where a backlight has failed), so I know the computer is running, but nothing even remotely usable.
I noticed just before the screen failed that the unit was getting very warm. I also noticed that the battery level dropped to around 60% after less than an hour of use on "auto brightness" mode. So I turned the unit off and disconnected the battery, hoping that if I let the unit cool down and put it a fresh battery that it would come back to life. Unfortunately, that is not the case. The screen is almost completely dark even after the unit has cooled and using a fresh battery.
Extremely disappointed that a device that costs as much as my LG OLED flat screen TV could fail so quickly and is pushed out to market with very little documentation (i.e. installing 3rd party apps).
Let's keep this thread posted with updates . . . good luck.
