How to Fix a Green Screen on a Sony PlayStation PS2

You unbox your newly bought PlayStation 2 and plug it in, sadly the screen looks like a 1980s Amstrad monitor. Relax. It's not dying, the output setting is wrong.

To fix this:
  1. Remove any discs from the DVD tray
  2. Turn the PS2 on
  3. Navigate to System Configuration using your controller
  4. Work down the menu until you reach Component Video Out
  5. Press (X to) Enter
  6. Change from "Y Cb/Pb Cr/Pr" to "RGB"
  7. Now you can leave the menu and load your game
