Why does my screen look like this? Help please

After attempt of replacing sim card slot

i ended with a screen problem

(the only thing i did wrong was scratching some of the silicone gray thingy stuck to the Middle frame )

Can this be a problem rooting from the sim reader soldering?

is my screen dead now?

Have you open the phone? Then look if the display cables are loose.

what claes said. also try cleaning all connections with 99% isopropyl alcohol. Also try a soft reset or battery pull.
