My screen suddenly "died" on my brand new Ramos W30HD, I had installed a billiard game and my wifes niece played the game about 30min. My wife just turned of the screen and put the tablet away. About 40min later I pressed the powerbutton and nothing happend, I thought I ran out of battery and put it into the charger. About 50min later I tried again, and still the same result. I can take screenshots, unlock the tablet and navigate on the desktop, start games etc. (I took a bunch of screenshots to figure out what I was doing) I can also connect it to my PC and it recognize it as a portable device. I've tried everything I found on the Internet about reset but nothing happens now the battery is dead, gonna put it in the charger and see what happens.. What can be wrong?
