OK, last thing I did was looking at cars on auto trader, shut it down for the night. I powered up the tablet next night, black screen. i can hear the startup music, screen is black. After a few moments in can tap the screen anywhere and hear an app start up, screen is still black. Powered it off, tried hard restart, screen still black. Tried this several times and once got some Chinese speaking thing running. Everytime it starts up I can hear the music but screen still stays black. Last thing I did was disconnect the battery, but all stayed the same.
