Installation of the REI Colormod Module
for a PU20 PlayStation Console
(Model SCPH-700x)

Making the connections between the Colormod Module and the PSX PC board

Pins 1-7

Pin #9 (Freq) is not connected on the PU-20 console

Correcting the color signal

Step 1
Desolder and remove the RFI shielding from the top of the mainboard.
Step 2
Cut the trace that runs from pin 157 of IC203 just above pin 157.
Step 3
Locate a pad further up that same trace and solder a wire from that pad to either the groundplane for PAL (SCPH-7002) consoles or Vdd for NTSC (SCPH-7000/7001) consoles.
Step 4
Resolder the RFI shielding in place.

Mount the Colormod board on the top plate of the PS by use of a ~5mm spacer. Then reverse the disassembly instructions, remembering to connect the wiring harness to the module before replacing the outer cover on the PS unit.
