How do I fix my screen it messed up internally?

Arianna basha, right now it sounds like you need a new LCD. You will have to open your tablet by removing the back cover with something like a plastic opening tool or similar. Pretty much identical as this one. Different model same idea.Then you have to remove the whole inside i.e. circuit board, battery etc. Once you removed all that, you need a hot air source to loosen the adhesive that attached the screen to the bezel. So it is pretty involved, bay after all that replace the LCD with a new one which is a INNOLUX N070ICN-GB1 and is readily available at multiple places. Post some images of what your screen looks like with your question. That way we can see what you see.
