physical control panel will not work at all

[Joe Nautic]

Hello, 

I have a cnc waterjet that I runs using a delta tau PMAC lite card on an old windows 98 pc. Today when I went to home it I get no response. I can not change the axis by the switch nor will any other switch work, Even to change it to homing or automatic mode. It has been working fine for years. Would it be safe to say that the problem is in the PMAC control panel board? I found one online but I want to be sure that is it because the panel board is not cheap. Is there any way I can potentially isolate the problem? Any input would be greatly appreciated.

The display showing all limits active might indicate the power to the limits and possibly the control panel has been lost. This could explain the inactivity of all the switches.
