white&black screen broken

[mimisike]

So my family has bought a really bad irulu tablet, Model AX304, however one of my family members were using it and well the screen looked kind of like this

BUT, the screen itself is not broken on the outside. I do not know if it was dropped, but i'm guessing it is damage in the inside. I'm ready to pull out my soldering gun. However i am 17, I have no idea how tablets work nor do i have any idea how laptops work considering the wiring for screens is the same. Can someone give me some insight on how i can fix this problem? I've opened up the tablet and am able to mess around on the inside but have no idea what to do.

TL;DR
Tablet is broken, internal problem.
model is irulu AX304
need help on repairing this, have some of required equipment

If requested I will upload a photo of the interior of the device

What you need is the lcd then. Whats on tiop is the digitizer which you said is not broken.

Sadly I did not find any replacements.
