hey to everyone. I am new here and not a professional vendor. I am the property manager for a YMCA in east TN. I am new to this job and have learned that we have a Snacktron 1 with a Maka validator. My boss wants me to get the validator working but he doesn't want to sink anymore money into it. He bought an ebay replacement and it didn't work either. Not sure if he bough the mech or the logic board. Anyway, the validator cycles when the machine is powered on but does nothing when a bill is inserted. Is there anything I can do to bring new life into it. If not, what mars unit should I swap it o
