The UGLIEST Repair of a Commodore 64 (Part 2)

Support Noel's Retro Lab on Patreon:   / noelsretrolab   Now that the C64 is fixed and with reliable power, we focus again on diagnosing and fixing the black screen. I try to make sense out of what we're seeing and start desoldering some chips, and more, and more... It ends up being quite an ugly repair, but at least things (sort of) make sense at the end.
