- 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-7502) consoles or Vdd for NTSC
- 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.
