I'd start off by checking the voltage supplies to see what state they are in. Then it might be worth checking the current draw from the battery to see whether that is reasonable. I would guess it should be around 200mA. If the supplies are working do you then get backlight on the screen. I.e. does it go white on turn on.
SeeedStudio should be a source of spare parts but for the standard voltage regulator / battery charging parts you can just try eBay.
Having said that, if any of the fault current flowed near the major Ics (logic Array, CPU) and took those out then the board is effectively a write off.
