I just moved and in doing so my TV was damaged. The cable was ripped
out of the back and part of the TV (where you screw in the cable) came
with it.

I have pictures of the part that was damaged but I don't know what it
is or where to buy a part to replace it. Help!!

See pictures below - it's the shiny silver box with a hole in it.
