That Amber Glow: Fixing a shed-found 9" composite monitor (USI Pi4)
About this video
Found in the same shed as the recent Apple II+, a broken USI Pi4 amber monitor is the next job, and the maker sets about getting it working.
Good to know: The tube and flyback hold a high voltage charge after unplugging. A knocked or cracked tube can implode, so protect your eyes and never lift it by the neck. Mains voltage is inside the set as well.
Why watch it
Related repairs of the same monitor model are linked under the video, along with period magazine pages on its product announcement, which gives context for anyone working on an amber composite display.
