Display bracket is not sliding out

The display of my ipod nano 4th generation has water damage, it just need a clean up, I've already removed all the 5 screws, the top and the bottom bezel but the screen is not sliding out I stopped trying to remove it because I bend the bracket where the hold button is attached, but not damaged, I really need any help that anyone could provide me about this issue, Thank you so much in advance, merry christmas!!!
