A high swr/reflected wattage problem can cause a serious shock also, such as the center conductor of the coax to the antenna not making proper contact to the antenna.
There are several ways this can happen, pl-259's not soldered on properly or I have seen a cheaper coax actually burn off inside at the pl-259 or just not make contact where it slides into the pl-239.
Another is the center conductor has broken somewhere in the coax other than at the ends.
Last but probably most important is a mistuned antenna, did you check to see if you still had an antenna? maybe someone stole it,lol never hurts to check.
