Triple Freedom C64 repair takes on a tricky black screen problem in a Commodore 64 and guides viewers through each step. The journey starts by investigating suspicious address lines A12 to A15, which set off alarm bells early. These lines produce unusual signals, leading to the replacement of the U13 chip, but the trouble does not end there.
Strange Capacitor Mystery
During the Triple Freedom C64 repair process, a mysterious green capacitor surfaces on the board. This extra part is missing from working versions of the same motherboard. Even after removing it, the Commodore 64 remains stubborn. With persistence, every RAM chip is tested and confirmed to be in good shape, but the repair journey continues.
Kernel ROM Under Scrutiny
Attention turns to the Kernel ROM after RAM and other components are cleared. Swapping out the old Kernel ROM for a good one brings the Commodore 64 back to life. The faulty Kernel ROM created misleading signals, making it one of the hardest issues to spot during the Triple Freedom C64 repair effort.
Oscilloscope Shows the Truth
With the oscilloscope, it becomes obvious. The broken Kernel ROM outputs noisy signals, while a good one is clean. That difference means everything for a working system.
This C64 repair demonstrates practical steps, smart diagnostics, and real hardware know-how. Watch the video to see this Commodore 64 get back in action!
