The high voltage supply was out of range. How do I fix this fault?

This is probably not going to be a fault that you as an enduser will be able to track down and repair.  If the fauklt is persistent after a reboot, then the power supply voltages will need to be tested to ensure that they are within specifications and if not the power supply will have ot be replaced.

Thank you, Dan. Is that the detector PCB below the FID electrometer pallet? There is a four-pin connector (red, black, two white wires) at the bottom of that board. The wires are labeled F-DET. What do you think about switching to the wires labeled B-DET and re-configging GC to use back detector? If they have the same power supply, I would expect to get the same fault.

No, the power supply is in the back of the GC, that PCB below the electrometer is for the detector control.  You could try moving the entire detector and associated boards to the rear or B-position but they share a common power supply and I would doubt that it would really be informative.
