Noel’s Retro Lab has 3 Commodore 64 units all with the “Black Screen of Death”. In this series videos Noel will trouble shoot each and attempt to restore them. This is Part 3 of 3.

“Commodore #3 had multiple issues. The lower voltage and the shorted address and data buses pointed the way to faulty PLA and SID (sniff). Along the way I encountered strange white flashes and a mysterious purple screen.”
