Installation of the REI Colormod Module
for a PU18 PlayStation Console
(Model SCPH-550x)

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

Pins 1-7

Pin 9 -> Freq (color)

Step 1
Locate the CXA1645 video chip near the multi-video out connector. Cut the trace coming from pin #7. Connect pin #7 with pin #1 on the same chip.
Step 2
Desolder and lift pin #6 of the CXA1645 and connect it to pin #9 of the wiring harness

The installation for an NTSC SCPH-5500/5501 PS is identical except that that pin #7 on the CXA1645 is connected with pin #12 on the same chip instead of #1.

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.
