In this video, I tackle a Commodore 64 with a classic black screen issue. Using a variety of diagnostic cartridges and tools, I narrow down the culprits to a faulty PLA, CIA, and SID chip. Watch as I troubleshoot the board, swap components, and get this vintage machine back toward a functional state.
