Zoom H4n Pro Repair

A Zoom H4n Pro audio recorder found its way to me, non-working. Recordings seemed to be silent, but with loud enough input you could just make out some distorted sound in the recording. After (unneccessarily) disassembling it completely, I found out that the power supply of the preamplifier board was sitting at around 0.8 V, which thankfully/boringly turned out to be the only fault in the unit.
