The problem with these chips is that they aren't soldered on the board well/correctly ... Most of the time, the crazy fix is to pull the board out of the machine and do a "solder reflow" ... this involves either a $2000 Infrared MAchine or the other two ways...
#1 Use a Heat Gun on just the chip. To do this you need to make a mask so that the other items on the board don't get fried or in the case of a capacitor, explode. This was my way to fix one ...
The #2 other way allows you to also keep your chaffing dish warm. Use some sterno in an aluminum cup and place it on the chip... then LIGHT IT ON FIRE. The sterno cup gets the chip hot and reflows the solder.
Crazy but true...
