Troubleshooting a "black screen" C64
About this video
A Commodore 64 mainboard (assembly 250407) powers up to a black screen, and the maker troubleshoots it, with links on PLA chips and on how the maker removes chips.
Good to know: Chip removal means desoldering: burns and fumes, and old solder contains lead. Needs board level fault finding.
Why watch it
The maker asks whether the board can be fixed. Background reading on PLA chips is linked, with PLAnkton details and a video from its creator.
