   I used to work under very difficult conditions which varied between
overheating and overcooling, together with anything from absolutely dry to
almost underwater (even actually underwater). We even had so much water that
copper tracks started dissolving from the circuit boards.
   Standard techniques that we used for fault finding included covering with
cloth to force overheating, liberal use of hair dryers (with or without
heating on) and spraying with non-flammable non-electrically-conductive
liquids to force-cool small areas. Dry joints often showed up while gentle
tapping with a screwdriver handle.
