This Bang & Olufsen Beovision 1 CRT TV had the audacity to emit smoke and then carry on displaying a perfect picture. A lengthy investigation eventually uncovered an X2 safety cap that had met a truly spectacular end. Came away with a cleaner TV and a great story.

Proper saga on this Sharp X68000 Pro II. Magic smoke from a reversed capacitor, an accidental probe short, and enough replaced components to fill a parts drawer before a single faulty transistor finally gave the game away. Got it booting and running R-Type, which was a hard-earned win. Video output later stopped working, so the story isn't entirely over.

PSU repairs on this Panasonic FZ-1 3DO required bridging badly damaged traces, and a missed ceramic cap connection sent the console into a reboot loop. Sourcing a replacement laser meant buying a whole other console, but it runs now, and has since gained an ODE with SD card access through the AV expansion bay.

Don't mix PSUs with incorrect mains voltages, kids. I accidentally did that on this Sony PlayStation NTSC-J in 2022, while repairing and testing the controller ports on a friend's PAL PS1. Years later, once PU-7 QSBs finally existed, it got the mod it was bought for: an xStation from a kit by Romain Brami, with DSP pins lifted, the resistor and filter by the master clock removed, three more resistors cleared from the QSB footprint, then the QSB soldered and the FFC folded up to the top side. An X-Reset QSB followed. Shortly after, the PSU turned hard to switch on, which was corrosion inside the power switch: stripped, scraped with a fiberglass pen, cleaned with isopropyl, then DeoxIT on the contacts and grease on the plunger.
