I have inherited a spa from the inlaws in hopes that I can figure out whats wrong with it without spending too much dough on it. I have voltage to the main board but no operation, no lights or activity in the touch pad up top. I can hear a slight hum which I think tells me the small transformer is powered up. I have tested all the small glass fuses and all test good. I have various voltages through out the board. I would like to know if there is a way to "jumper" around the touch pad control up top to either rule it as a problem or verifiy that it is working properly. I have a good understanding of control boards and their operation what I am looking for is a way to pinpoint the problem without just throwing parts at it until it works. Thanks a bunch Bob
