This occurs when heat builds up on the Vertical IC and causes
the metal to expand and contract. The pins on the chip break away
from the solder joint causing a high impedence (open circuit) connection
This chip consumes quite a bit of power, meaning it gets

This is the bottom of the board. To fix this problem
you need to use a pencil tip soldering iron and reheat
each solder joint. I'd also recommend adding some additional
