pp256 need help

In need of tech support,

I has in the garage tonight finishing work some cutting and welding on my cnc router/ plasma table ( that i am planing on buying an 80s for) i am building and the fiance came out in the garage to check progress when she tripped on my tourch cord pretty good. she is all right but my pp256 is not. right now it is displaying 256 on the amperage read out no matter what mode i am in and is un-responsive to the amperage control knob. after looking further it aprears the the front conector for the torch was pulled out and wires were loose inside of the connector, my guess is that something there got shorted. I fixed the connector machine side and switched to my other plasma cable and still same issue, i have only tried it twice once with bad torch and once with second tourch. help please!?
