Tims Retro Corner | Commodore Plus/4 Black Screen of DEATH @TimsRetroCorner | Uploaded December 2023 | Updated October 2024, 4 hours ago.
Kindly sponsored by PCBWay.com $5 for 10PCBs. Just a week after building a new power supply for it, my Plus/4 decided it was no longer for this world, and produced the dreaded Black Screen Of Death.

So what's wrong with it? And Can I fix it...?
