    I have a samsung galaxy s4 tablet. SM- T237P. I was using my tablet perfectly fine when suddenly, the screen froze and the display screen faded, changed color and made a bunch of lines. The screen isn't cracked but I did drop it the night before but it was fine.

    Did something loosen on the inside? I've opened it, what do I have to pick with to get my screen back to normal again?

    Welcome to Android Central! Moved from the S4 forum to the Tab 4 forum.

    Look at teardown videos to see where the video connectors are, and check to make sure those connections are tight: https://www.ifixit.com/Guide/Samsung...assembly/76451

    If all connections are intact, then the screen itself might have died.
