This is similar to a bad solder joint, but sometimes even less obvious -- a hairline crack in the foil on a circuit board. Try examining the board tracings with a magnifying glass. If you find a break or questionable spot, the fix is to scrape off any coating on each side of the break in the foil and solder over the spot.
