C64 Repair: A Choice of Three Possible Faulty Chips and how I decided which one was faulty!

A C64 Repair with a twist! Trying to pin down the fault in this Commodore 64 using nothing but the power of my mind and a workbench full of tools. Also the internet. And experts I can ask for advice. Apart from those things, just the power of My Mind! And my eyes. Those helped too. Completing the repair of this C64 first seen in the Topdon thermal camera episode.
