Sony — PlayStation
Controller ports on this PAL PlayStation had stopped working, and the fault traced to a blown fuse. It was replaced using the fuse pulled from the NTSC unit whose PSU had gone up in smoke that same evening, and a new part went into that console.
A few years ago, back in 2022 (when I blew up the PSU on an NTSC PS1) I was tracing down a fault in this PAL unit. Controller ports were not working, turned out to be this fuse. I took the one from the NTSC unit and fixed the PAL one with it. I put a new part in the NTSC console.
Here's a video of the PAL unit working after the fuse replacement.
