Take
out any screw that goes through a metal connector on the circuit board.
Clean the screw with a wire brush, clean the connection point on the
circuit board and where the screw goes into the case.
Before you put
the screws back squirt some wd40 or or put some vaselene on them and
tighten them, it will help stop the dust from making a bad contact.
