My father was a broadcast engineer in the late 1950s (with a First Class FCC Radiotelephone Operator's license, which he was quite proud of and which he maintained for a long time), but by the early 1960s he was a self-employed TV repair person. He used to get shocked fairly regularly*, but the most common outcome of such an event was a gash on his arm as he reflexively
jerked it out of the innards of whatever TV he was troubleshooting.

* One of his standard techniques was using an axial lead capacitor with fairly long leads to shunt a (suspected) bad capacitor. These were HV capacitors with... umm... high voltages on 'em. He was, in many cases, reaching into a TV with the back off but the chassis still installed in the set; kind of a dark, constrained environment (especially with a 'table model' TV). Once in a while, inadvertent repairperson/HV contact was made.
