I was looking to replace the glass apple logo with an led one. I have my thunderbolt display apart and as you can see in the last photo of this guide, there seems to be a silver foil over it. I do not want to tamper with it, but does anyone know if I will ruin anything if i take that foil off thats stuck to the metal frame? It appears that the apple logo is just glass, and that the foil on the inside is so sealed that it makes the apply logo look black. Any comments?
