CD-i:CD-i 220 RGB Mod

As long as your NTSC CDi has the Sony CXA chip, this mod will work. PAL 220 boards should have the RGB SCART built-in.

Required Materials
You'll need a few tools for this mod:
 * Soldering skills
 * Torx screwdriver set to open the CDi case and internals
 * Philips head screwdriver
 * Soldering iron / solder
 * Thin gauge wire
 * Four (4) 75 Ohm resistors, the lowest tolerance possible.
 * Four (4) 220uF/16v capacitors
 * RGB output port (any port will work, just make sure you pick a port with a matching RGB cable).

Instructions

 * 1) Start by removing the top cover:  Remove the two torx screws on each side and the top three screws in back: [[File:CDiRGB01.jpg]]
 * 2) Next, remove the outer screws that contain the expansion socket.  These screws were one size larger torx than the case screws: [[File:CDiRGB02.jpg]]
 * 3) Before you can remove the expansion socket, remove the two screws on top, then pull up from the area by the top screws to release the socket: [[File:CDiRGB04.jpg]]
 * 4) You'll find the Sony CXA chip underneath the expansion slot: [[File:CDiRGB05.jpg]]
 * 5) Solder R, G, B and CSYNC (please see the note about csync below) directly to the chip, as shown here: [[File:CDiRGB06.jpg]]
 * 6) Here's the actual chip diagram, in case you're interested (click for full-sized): [[File:CDiRGB07.jpg]]
 * 7) Next, choose a mounting location for your RGB port.  It's recommended to use an 8-pin MiniDIN and mounted it where the RF adapter went, allowing the mod to be 100% reversible, without any cutting at all. [[File:CDiRGB11.jpg]]
 * 8) Run all four video lines to the output.  Make sure each line has a 220uF/16v capacitor on the end, as well as a 75ohm resistor on each line as well. [[File:CDiRGB12.jpg]]
 * 9) Find a ground point to solder to your connector.  There's no "special" place to get ground, anywhere will do (just verify with your multimeter).
 * 10) If your RGB connector routes audio through it, wire that in as well: [[File:CDiRGB13.jpg]]
