Mp4 player screen. my screen is cracked on my mp4 player and I would like to replace it - it is

Question

my screen is cracked on my mp4 player and I would like to replace it - it is still working fine, just a broken screen - is there anywhere I can purchase a screen or take it somewhere to be repaired?

It is white looks just like an Ipod but a smaller version. it has arrows pointing left, right,up,down
the crack is in the middle of the screen and it is black where the crack is. Also, it has 3 white lines going down on the right side of the screen. still working proporly, just need the screen to be fixed.
