well I'm kinda hesitant to reccomend this, and I cant believe I'm gonna do this but ... inkjetperformance.com in GA, will repair,rebuild. You can send them just the board and they will trouble shoot and repair. I sent the board to my falcon outdoor to them and they fixed it for about 350.00, fixed the pump circuit and print circuit. I will warn you that the customer service SUCKS ! but they did fix it so ... its up to you but be forewarned.
