My xbox 360 slim button keeps pressing itself....I broke it when i opened the console(hell i also stratched the hell out of the back sticker so i dont think someone would buy it)..I think i put the strap in the wrong place...How do i fix this?the eject button works..

Disassemble it again and see if a wire has been severed.
Otherwise you'll need to get a new casefront for it.
