Troubleshooting and repairing another Commodore 64 board (ASSY 250425) with a weird scrambled characters/flickering lines fault. // Kindly sponsored by PCBWay - Get your first PCBs free! - https://www.pcbway.com/
The IC puller I'm using is a Jonard Tools EX-2, available from various electronics resellers.
Here's some handy resources I refer to when troubleshooting and repairing C64s:
The Pictorial C64 Fault Guide is here: http://derbian.webs.com/c64diag/
Ray Carlsen's troubleshooting and repair guides are here: http://personalpages.tds.net/~rcarlse...
You can get the .bin files for various C64 diagnostics cartridges from World of Jani (in case you want to make your own or try in an emulator): http://blog.worldofjani.com/?p=164
Here's the GitHub with Sven's diagnostics harness: https://github.com/svenpetersen1965/C...
