From my experience - it's likely a hardware issue. I don't think I've ever had a hyperdeck lockup unless it was a hardware issue. ( I've repaired a few , and failed to repair a few ). The most common repairable issue with these is an overheating part related to the step down regulators on the main board.

I repaired them myself. There are 3 parts common with each of the voltage regulators. (5v/3.3v/1.0v, maybe more - I'm writing this from memory ) A switched mode IC. A dual mosfet ( 8 pin soic ) and a 100uH power inductor ). The switched mode controller is very difficult to remove as it has a central metal slug underneath soldered to the pcb.
One or more of these components was failing or had failed in the units I managed to repair. It's possible that the inductor is underspecified ( peak current ) and degrades over time. This then appears to cause failure of the mosfet and possibly the switcher IC. A classic sign of this impending problem is the inductor turning brown ( normally a silver grey ).
The hyperdeck pcbs have small green surface mount links to isolate the regulated output from the rest of the board. I'd suggest these be removed in order to confirm that the problem is with the psu side of the circuit rather than a fault in the wider circuit.
