Electrical Help with MP40 gen 2 driver

[animalkingdom]

Well Ecotech doesn't make or carry the board for the gen 2 driver anymore. I am pretty sure mine is bad as I get a solid red light. The power supply and motor still work...tested on another mp40 driver. Anyone have any ideas on fixing the board or trouble shooting it? I cant justify the $130 Ecotech wants for a new style driver given the motor and the rest of the pump is so old.
Here is a pic of the board in question:

I don't see much on that board that's easily servicable except the 6 large transistors (most likely power FET's) They are probably pretty cheap from MCM or DigiKey, so I would order half a dozen and replace all 6. Other than that, unless you know or know someone who knows how to reverse engineer complex circuits, you're probably out of luck.
