PS1Digital Internal Installation for SCPH-550X and SCPH-700X (PU-18 & PU-20)

Disclaimer:
This kit is for advanced installers only. I am not held responsible to damage to your console or damage to the kit. Each kit is personally tested by me and confirmed working before being shipped out. This document assumes you know how to take apart the PS1 with basic tools as these instructions will not be included.

This kit uses Zero Force Flip Lock Insertion FFC for the Flex cable. FFC connectors are fragile and can be broken easily if care is not taken.

Please review the installation video. Always reference these install docs and use the video as an aid for techniques on how to preform the required steps.

• Main PCB w/thermal pad attached
• GPU Flex
• Audio Flex
• Controller Flex
• Serial Flex
• WiFi Antenna
• 2x spacers

• Temperature Controlled Soldering Iron
• Non Corrosive, No Clean Flux (I recommend Kester 959T)
• Solder Wick
• 99% Isopropyl Alcohol
• Multi Meter
• Pliers

Step 0 - Important Information

OSD Hotkey = L2 + R2 + SQUARE + X + Start

**Note: Select buttons inside the OSD uses R1 & L1

By default the PS1Digital board is setup for DFO (Both NTSC & PAL frequencies) If you would NOT like DFO support then (If you are unsure then skip this):

• Remove solder bridge from pads 1&2, 4&5
• Create solder bridge on pads 2&3, 5&6
• Create solder bridge on JPCLK
• Do NOT remove the resistor as outlined in the Motherboard Prep instructions below.

Step 1 - Heatshield modifications.

• Remove the pressed dimple with side cutters
  
• Pull up metal tab with pliers
  
  

Step 2 - Motherboard Prep.

• Pull off the copper shield
  
• Remove solder from the areas in yellow to remove metal shield.
  
  
• Remove Serial Port
  
  
  
• (PU-18) Remove Surface Mount Components highlighted in yellow
  
  
• (PU-20) Remove Surface Mount Components highlighted in yellow
  

Step 3 - Installing All Flex cables

• Install Controller Flex
  
  
• Install GPU Flex (***Make sure you have the alignment correct, the flex connects to the copper pads adjacent to the pins as well)
  
  
• Install Serial Flex
  
  
• Install Audio Flex (Your audio IC might have 2 less pins, this is fine)
  
  

Step 4 - Mounting PS1Digital Board and basic testing

• Reinstall Motherboard into PS1 case and put the two spacers in place. (Make sure the thermal pad comes out of the ESD bag, in some cases it might be stuck to the inside.)
  
• Install the PS1Ditial using the 2 supplied spacers.
  
  
• Do a quick voltage rail check, make sure 3.3v and 5v are not shorted to ground. Refer to this Diagram
  
• Attach GPU Flex, Audio Flex, Controller Flex, Serial Flex and Power connector from power supply (Make sure to not put any pressure on the flex soldered connections)
  
• Power up the console and verify you get a SOLID light on the PS1Digital board and the console boots up properly. You will boot up to the memory card screen. If no video (or garbled video) or audio (or garbled audio) go to the troubleshooting section at the bottom.
  
  
• Remove power cord and disconnect power cable. Push the GPU flex down and slightly crease the cable. This removes pressure from the solder joints.
  
  
• Attach WiFi Antenna and remove plastic from Thermal Pad.
  
• Reinstall Metal Shield with screws and secure WiFi Antenna
  
  
• Reattach Disc Drive
  

Step 5 - Final Testing

• Plug in controller and turn on console. Open up PS1Digital OSD by holding "L2 + R2 + SQUARE + X + Start" The PS1 does not always poll the controller (For example during the BIOS boot screen)
  Go to the Test Info Screen. Insert a CD that has a 24bit FMV video (All EA games FMV intros are 24bit) and push down on the lid switch. (You should have all hearts)
  

Step 6 - (Optional) PSNEE Modchip setup

• Attach the points located next to the ESP32 to the points in the diagrams below. There are alternative points listed, only 4 wires total should be soldered. Once wired in the modchip will work automatically.
  
  PU-18 Bottom Side
  
  
  PU-18 Top Side (WFC must be soldered on bottom)
  
  
  PU-20 Top Side
  
  
  **** JP consoles will need a bios swap to allow region free support.

Step 7 - Final Assembly

• Install the plastic cover
  
• Install top case and reinstall screws
• Congratulations you are done!

Troubleshooting No Video after install

Be smart about what you do at this point. Just blindy going into troubleshooting will likely result in more damage.
