Occasionally when troubleshooting a board, I suspect there is an issue with ground potentials between an ICs pins causing either signal corruption or even latch up of the device. For simpler boards where this is possible, here is a link, below, to one technique that I use. Before a layout can be fixed, this could also be used as a temporary rework, especially if all the ground pin connections are not required.
