My son has a Nextbook 10.1" tablet that connects to keyboard to make it a laptop that was not dropped and the screen is not cracked but now has the lines across the screen and cannot get anything to work on it or screen to rotate. Can't even get it to power down and wondering if there is an easy fix or if it is totaled and I need to buy another one, buy a new screen or buy the LCD? How do no check to see it its the LCD ? And are there any other options I may have that I have not mentioned?
