You cant tell much from looking. Other than that the soldereing is not very good!
Basicaly its quite modular..
The large black chip is the controller and is replaceable
The pololus are all indepent... they are replaceable
If the MOSFET's are dead you have to unsolder them, but they are replaceable...
I would only consider the board dead if the serial chip dies, as its a pain to replace, or a track burns out.
But ultimatly its up to you when you want to call it dead.
