Oven and Broiler will not light - no gas, but DSI board is good

Problems began with the broiler shutting itself off about a minute. The bake function worked fine. After about a week of restarting the broiler, both broil and bake functions went dead and will not heat. Had a chance to try my DSI board on a friend's identical stove and it functioned fine. Got a copy of Whirlpool's DSI troubleshooting guide and determined that the main circuit board was supplying 120V to the DSI board, connector J1, pins 6 & 7. But the DC power to the safety gas valve was not there on either broil or bake measured at J1, pins 1,2&3. Next measured the resistance of the gas valve solenoid coils at the J1 connector at pins 2,3 and 1,2 and both measure about 200 ohms. When turning on the broil or oven, you hear the relays click and it sparks 4 times before quitting, but there is no gas flow. The DSI troubleshooting guide mentions that the the DSI board self-tests and then provides spark and opens valve. For some reason the DSI board is not providing the DC power to the gas valve, but when we install that "bad" board in another stove it works fine. I'm wondering if somehow the main circuit board is involved in this action and it could be faulty? Any one have any ideas about where to go next??
