A good, skilled electronic tech with an interest in repairing these boards, with out the proper documentation on them, would reverse engineer '''a known good board''', to have general understanding of the board. They would keep a known good board for a reference board. That way they could compare component, electrical and frequency values with problematic boards. They would have an oscilloscope, a function generator, a DC power supply, multimeter and logic probe as minimal test equipment. For repairing the boards, they may have a reflow oven, smd rework station, and a soldering iron, among other things.

Bottom line you need to have a firm grasp of electricity and electronics. You need the proper test equipment, the knowledge of how to use them and what values you should be seeing to determine the good, the bad and the ugly.
