Use a Q-tip that has been dipped in rubbing alcohol to gently clean any membrane contact that is damaged or where conductive painting is missing. Do not rub too vigorously, as this could erode the conductive paint and stop the button from firing when pressed.

Examine the battery connector's terminals carefully for any loose solder connections.
