Well, that's quite a challenge - you might find a solution if you provide even more information: what chipset is used? I can't identify the chips - is it a rockchip or Actions one?
There exist schematics for Actions chipsets and if you're lucky your board is designed following the principal scheme.
You can find 2 pdf's for Actions ATJ 2091 here:
ATJ 2091 pdf (1)
ATJ 2091 pdf (2)
Be warned, your player can use a different chipset and all likely will use a different layout.
But at least this is what I'd try to do: find a principal layout for the chipset used, try to understand the schematics and look for the parts.
Good luck!
