Please help! I hope I'm in the right place to ask but I'm horrified right now. My Mom's tablet is in trouble. I have no idea what's going on with the screen. For sure, I never dropped it nor splashed it with any liquid. Please look at these photos (in URL) for your peruse. What could be the possible causes of this? 
It will be really a great help if I know the probable cause alone, I'm planning to get this fixed on an authorized repair store soon. The device is Acer ICONIA W510.
