Colour Correction Module (CCM) Guide for Playstation Model SCPH 5502

What is the purpose of a Colour Correction Module?

When you load NTSC (USA/JAPAN) game and display it on PAL (NZ) TV system the picture will be displayed in Black and White as in the left TV picture below. With the installation of a Colour Correction Module this will correct the problem and allow the NTSC game to be displayed in Colour as in the right TV picture.

NTSC-PAL Fix Example

Note: If you have a late model TV that is NTSC compatible then you most likely will not need to do this. Try it out with a NTSC game and check, you may have to change modes on your TV to NTSC or PAL/60 (consult your TV user guide :o) Otherwise you will have to install the Colour Correction Module.

Note: You still need to have a Modchip or Stealth ModChip installed to load Imports or Backup games.

Minimum equipment required

Philips #2 or Medium Philips head screwdriver.
Soldering Iron 15w/25w
Solder
Small Jewellers screwdriver
Hot Glue Gun (optional)
Insulated Tape
Clean Work Area
Time - Take your time

Step 1: Indentify and Disassembly of your PlayStation

Before installing the Colour Correction Module ensure that your PlayStation is a model SCPH 5502, turn it over and look at the label on the bottom of the case as shown below. On the top right corner of the label it will indicate what model you have.

SCPH 5502 Model Identification Info

Use the SCPH 5502 Disassembly Guide - Then proceed to Step 2.

Step 2: Familarise yourself with the Colour Correction Module

You will have received 1 x Pre Assemble and tested Colour Correction Module (CCM) with double sided sticky pad, and a piece of Kynar wire. The wires on the CCM have been cut to the correct length and tinned.

RED wire	+ 5v DC
BLACK wire	Ground
BLUE wire	Frequency Out

Step 3: Locate Installation Area on Mainboard

Pick up and turn the Mainboard over so that the bottom of the board is facing you.

The Red box in the upper right corner is where the BLUE wire is to be installed.

And the Red box in the lower right corner is where the RED and BLACK wires are to be installed.

Step 4: Lift 2 pins on the CXA 1645M Video Encoder Chip

Okay this is the trickiest part and takes the most care. The CXA 1645M Video Encoder chip is the large chip located in top right corner as in the picture in Step 3.

You have to carefully lift PIN 6 and PIN 7 up off the Mainboard as in the picture to your right. I use a small jewellers screwdriver and place the blade between the pin and the Mainboard, apply your soldering iron to the pin and carefully using the adjacent pin as a lever to lift the pin up slowly. Repeat for the other pin

How to Lift Pins 6 and 7 on the Video Encoder Chip

Once you have lifted up both PIN 6 and PIN 7 on the Video Encoder chip, ensure that the pins are completely lifted away from the Mainboard and no solder is bridging the pins to the Mainboard as in the picture on the right.

Example of Pins 6 and 7 lifted up from the Mainboard

Step 5: Solder in the Wire Link on the CXA 1645 Video Encoder Chip

Tin PIN 1 and PIN 7 with a bit of solder. Using the piece of Kynar wire supplied, solder one end of the wire to PIN 7 and the other end to PIN 1 as shown in the picture.

Step 6: Connection of the RED (+5v DC) wire

Tin the pad on the Mainboard with solder indicated by the Red arrow where the RED wire is soldered to and then solder the RED wire to the pad.

You can place a piece of insulation tape over the connection point if you wish.

Step 7: Connection of the BLACK (Ground) wire

Tin the pad on the Mainboard with solder indicated by the Red arrow where the BLACK wire is soldered to and then solder the BLACK wire to the pad.

You can place a piece of insulation tape over the connection point if you wish.

BLACK Wire / Ground Location

Step 8: Connection of the BLUE wire to the CXA 1645 Video Encoder chip

Tin PIN 6 with a bit of solder, then solder the BLUE wire to PIN 6 as shown on the picture.

I use a hot glue gun and squirt a bit of glue over the connection, to give it a bit more mechanical support to reduce any stress on the pin.

Step 9: Mounting the Colour Correction Module

Position the 3 wires over to the top right corner of the Mainboard as shown in the picture.

Do not put any un-necessary strain on the BLUE wire.

It is a good idea to tape the wire down to the Mainboard to reduce the chance of wires getting pinched when re-assembling.

PLEASE DOUBLE CHECK YOUR WORK AND ENSURE THE WIRES ARE GOING TO THERE CORRECT POINTS AND THERE ARE NO SOLDER BRIDGES ON THE VIDEO ENCODER CHIP BEFORE PROCEED TO THE NEXT STEP.

Wire Layout

Replace the Mainboard back into the bottom case and carefully route the 3 wires out between the bottom of the case and the Mainboard ensuring the the wires will not be pinched or obstructed.

Re-fit the FIVE screws as per Step 5 of the SCPH 5502 Disassembly Guide

Where the wires exit from between the Case and the Mainboard

Remove the protective cover from the double side tape on the bottom of the Colour Correction Module and stick down on to the Metal Base Plate as shown.

Now Proceed to re-assemble your PlayStation as per Step 4 of the SCPH 5502 Disassembly Guide

Testing and Trouble Shooting

To test your Colour Correction Module installation, insert and load up a NTSC (NTSC/JAPAN) game as you normally do, and you should see it being display in glorious colour, if so well done.

Still in Black and White?
Check to ensure that:
- You have lifted the correct pins on the CXA1645 Video Encoder chip in Step 6
- You have installed the wire link on to the CXA1645 Video Encoder Chip as in Step 7
- The +5VDC and Ground Wires are connected to the right place as shown on the diagram as in Steps 4 and 5.
- You have not pinched any wires when re-assembling, especially when routing the wires out between the Mainboard and the bottom part of the case.

PlayStation Shutting Down when turning on?
Check to ensure that you have not pinched the RED wire on the RF shield (Tin plate) in the bottom of the case. This will cause the +5VDC to go short circuit to ground and may blow a fuse or cause the 5 volt regulator to shut down. This is why it is a good idea to tape the wires down on the bottom of the Mainboard as in Step 9.

Picture Fuzzy?
If you are experiencing a fuzzy picture this may be due to the Blue (Freq Out) wire being to long and this wire introducing noise in to the video signal. This should not happen with any module that I supply as they are trimmed to the correct length. The Freq Out (Blue) wire should be kept as short as possible. This is applicable for all Colour Correction Mod circuits

Picture Rolling / Flickering?
Some Televisions generally really old ones and some of the cheaper brands may suffer from a rolling / flickering picture when you load a NTSC game (PAL games do not cause this affect). This is a Television related problem where the Television is not able to synchronise to the NTSC (60Hz) frame rate that the PlayStation injects into the Television when loading NTSC games.

How do you stop the picture from rolling? The simplest way is to change your Television to something that can handle the 60 Hz frequency. Most modern Televisions are able automatically adjust frame rates. The only other way is to adjust the Vertical Hold Trimpot. On older Televisions this maybe a knob at the rear or on the front panel Television usually marked V-Hold or Vertical Hold, it is just a matter of making a slight adjustment to this knob and the picture will become steady again. Some TV's you may have to get inside the to make the adjustment to the Vertical Hold trimpot. Use a trimming tool (looks like a plastic looking screwdriver)

WARNING: I DO NOT recommend that you do this your self as you will be exposed to very LETHAL VOLTAGES - 20KV (20,000+ Volts), it is best left to some with experience.
