My tablet looks cracked but its not cracked and it looks like it has water damage but im 100000000% sure it was never anywhere near water. I got it about 7 months ago. It started doing this about 3 days ago after not turning on for like a week.
@humanbeing37 first you want to let us know what model your tablet is. After that you want to post a couple of images of what your display shows. Use this guide Adding images to an existing question for that That way we can see what you see. It is entirely possible that your LCD is cracked but your touchscreen intact. Therefore you will not feel its cracks.
