White bar on screen and other problems

The "strange bronze color" was the airgap between the glass and the LCD screen. The glass is adhered to the LCD with an OCA (Optically Clear Adhesive), but if there is any air bubbles trapped in between (or get in between at a later time) they often appear bronze as it refracts the light in such a way that it makes LCD look like such.

That could be repairable, or simply ignorable, but the white lines/section indicates that you didn't just separate the glass, you tore or otherwise damaged the ribbon cable at the point it connects to the LCD. Effectively severing the connection that tells the screen what pixels to color what way. In essence, the screen works but gets no instructions other than "turn on" in that white section.

That is not repairable, unfortunately, and the entire screen will need to be replaced.
