Miller aerowave TIG welder broke, amperage HIGH, cannot change it

[ichudov]

My coworker has a Miller Aerowave TIG welder. It did work previously. Now it does not work. The amps display shows a very HIGH number that cannot be adjusted with amperage knob. It does weld at that extremely high setting and melts welding rods.

I have some pictures of the welder and board LEDs at:

Would anyone suggest a solution? Also does anyone know a good welder repair shop on the Chicago area? Thanks
