There are a few "ifs" here. Diagnostics are imperfect, and so that error message may or may not point to the chip at F12. But it could also point to something related to the chip at F12 (such as connections, as suggested by benjqvps). And since we don't know exactly how the self-diags work, F12 may not be a problem at all.

So, the first thing to do is to perform a careful visual inspection. Reseat all chips and connectors. Verify that the supply voltages are within spec. Then try replacing the chip at F12. Keep peeling the onion, a layer at a time, until you've shed enough tears.
