Aqila - Extruder not extruding

Voxelab Aquila ... extruder is not extruding ... the motor is not turning ... have done the following ...
Switch the leads to the Y motor with the lead to the Extruder (here after referred to as E) motor ... E motor works, Y motor does not work
Moved cable from E motor to X motor .... X motor does not function
Unplugged E cable from mother board and plugged into Y connector on mother board ... E motor functioned
Plugged Y cable into E connector on mother board ... Y motor did not function

From what I see it is in the Motherboard that there is a problem. Besides replacing the mother board, is there anything else I can do???
If no other option, any idea where I can get a mother board inexpensively?

Thanks in advnce ... Sadened Printer
