Some PS2 fat motherboards have a large crystal (18.432MHZ) in the way. The flex can still be installed with this crystal. However a low profile cyrstal with identical freqency can be used. IE: ECS-184-18-23A-EN-TR/2213742
Kit includes:
- PS2 Fat Main Flex
- PS2 Fat Controller Flex
- PS2 HDMI Mount
- Plastic Mount
- Mini Flip HDMI Adapter
- M3 6m Screw (2x)
- M3 Nut (2x)
- M1.6 Screw (2x)
- M1.6 Nut (2x)
Items required
- Temperature Controlled Soldering Iron
- Leaded Solder
- Non Corrosive, No Clean Flux (Amtech 559 / Kester 959T)
- 99% Isopropyl Alcohol
- Multi Meter
- Solder Braid / Desoldering Tools

This guide will not go over the tear down or small nuieces of the installation. Please watch the installation videos for this information.
The typical install procedure is:
- Test the console
- Teardown the console
- PS2 Main board prep
- PS2 Main Flex installation
- PS2 Controller Flex Installation
- Reset Hookup
- Testing
- Reassembly
Step 1 - PS2 Fat Board Prep
Click to expand/collapse
Components highlighted in yellow need to be removed. The 18.432MHZ crystal can be replaced if chosen at this time.
The areas marked in purple are where the flex will be soldered, Pay attention to the 5v and 3.3v areas.
The toslink port also needs to be desoldered and removed.

Step 2 - Installing the Main Flex
Click to expand/collapse
It is highly recommend you use lead free solder. The solder used in the PS2 has tin which can create micro cracks if leaded soldered is used and not mixed well. If you prefer to use leaded solder you need to wash the pins (mix) or remove the lead free solder all together. After installing many kits I personally prefer to just use lead free.
Refer to this image for the pinpout:
All motherboard revisions have the same video and audio hookup points. The 3.3V and 5V can be different. Please refer to these images in step 1 for hookup points.
For the rest of the installation I will be installing into a GH-023. If your motherboard is different continue following but use the motherboard 3.3V and 5V hookups in the images above.
Add a small piece of kapton tape to the motherboard in this area so the pin is not shorted.
Align the main flex and solder into place, also add kapton tape in this area so the 5v is not shorted.
Solder the 5v line.
Solder the audio flex leg to the audio ic.
Step 3 - Installing the controller hookup.
Click to expand/collapse
There are two ways to setup the controller hookup. Using the supplied flex or with wires. The flex is difficult to solder so using 30AWG solid core wire is also recommend.
FLEX
Click to expand/collapse
Align the flex and solder into place. Confirm the traces are on the flex are facing up.
Align the controller flex on the main flex and solder into place.
Wires
Click to expand/collapse
Refer to your motherboards pin out and run wires from each alternative place to the main flex.

Step 4 - Installing the reset line
Click to expand/collapse
Run a line from the reset test point to the point on the flex.
Refer to your motherboard below:

Step 6 - Testing
Click to expand/collapse
Its possible to test the console with it partially dissaembled. Be extremely careful, there will be live a/c mains.
Before testing its highly recommend you test each pin to verify no pins are bridged. Use the pinouts page for support.
Partial shorts (100ohm) are expected between ground and the power rails from bleed off resistors.
Before attaching the retro gem confirm the analog/composite video still work correctly. If you have any problems with composite this will signify you have bridged or discconneted pins.
Step 7 - Mounting the GEM Board
Click to expand/collapse
Bend the main flex as shown.

Choose your model:
SCPH-5000X
Click to expand/collapse
Attach the top and bottom metal shield and install the fan.
missing
Mount the power supply (don't forget the plastic insulator) but do not screw it into place. Test fit the GEM board. Some power supplies might have a metal shield or components that are in the way. The components can be tilted out of the way. If you have one with the heatsink shield in the way, this will have to be cut.
Make sure the flex cable routes under the retro GEM mount
missing
Secure both the power supply and retro gem with the oem screws.
Route the flex cable as shown and insert into the FFC of the Retro GEM.
