It's not easy to get a CPU chip failure reliably diagnosed in the field. Even if you manage to do the trial and error component swapping dance pointing to the CPU, you don't get very good confidence. Might be that new CPU taxes the power feed less or there was misapplied cooling paste or a bad contact in the pins etc.
