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.

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.

  • Make sure all cables power/hdmi/tv are all tested and working.

  • Is there a power issue?
       Does the PS1Digital LED turn on?
          -YES then likely not a 3.3v power problem. (Could still have a 5v power issue)
          -No then likely a 3.3v power problem.
       Verify 3.3V and 5V voltage on the PS1Digital board with the console running: Power Pinouts
          -No 3.3V voltage. This is a major problem there might be a bridge/short on the GPU flex (refer to pinout). If shorted a fuse will be blown. You can confirm this as there will be no analog video. Fix the short then the fuse and try again.
          -No 5V voltage. This is a major problem there might be a bridge/short on the audio flex (refer to pinout).

  • Run the quick self test
       Hold down the reset on the PS1 and verify a test pattern appears on the screen. You should only need power and a tv hooked up for this to work. The image might have some corruption, this is expected.
          -No test pattern appears, re-check voltage and hdmi equipment, also try another tv.

  • Test pattern appears fine. Verify Analog video works.
       -No analog video then there is likely a bad connection on CLK/PCK on the GPU flex. (refer to pinout)
       -Yes analog video works there is likely a bad connection on VSYNC/HSYNC on the GPU flex. (refer to pinout)


  • Step 13 - Troubleshooting No Audio after install

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

  • Make sure all cables power/hdmi/tv are all tested and working. Is the TV on mute? Volume Up?

  • Does analog audio work?
          -YES then likely a poor connection on the flex (refer to pinout Focus on SCLK, SDAT, LRCK)
          -No then likely a bridged connection on the flex (refer to pinout Focus on SCLK, SDAT, LRCK).
