ES-48-750W Parts or Replacement

Has anybody had any luck finding parts or replacing parts in any of the ES line? I have ES-48-750W that will not boot. Took it apart and it very obviously has a daughterboard that took a hit.

Anybody know where I can find a replacement of just this board? Is it even economical to do this?

Numbers from the board are as follows:

KM127H509

ES2400000T0A LF

2188007141-05L5

13-02092-10

11-02045-09

94V-0 MV-4

E89382 / 1439

Google search for each of those turns up nothing.
