Everything else seems to work fine except it freezes at random but i have no idea why this is here. I wonder if this black spot has something to do with it. i can sometimes get the backlight to come on but it eventually goes back off. i can also sometimes get the spot to go away.

i don’t think it can be saved but i figured it was worth a shot

@jarhead1 that is a broken LCD. Tough to replace those. iPod Nano 4th Generation Display Replacement

That black spot is a result of the LCD being squashed against the backglass. This is a result of the battery expanding, as the iPod nano’s internals are closely packed together, in a way that, if the battery expands, there’s no room to expand. Note: this can happen on any model of iPod nano.
