SCPH-1000 - Sound issue

[Masejoer]

I'm experiencing a very similar issue on a model 1001. Startup sound is distorted, nearly the same as in the video linked in this thread. System looks to be in mint condition (as are the controllers), screw removals cracked loose and inside is pristine. Probed every chip pin around the audio section of the board, compared continuity against probing points around the board - there does not appear to be a disconnected solder joint. CD music plays fine, splash screen/startup music and most in-game sounds are distorted.

Really don't want to give up on this board, nor change too much - it's difficult to find a system in such clean condition throughout after 25 years.

Send me the faulty PU-7 if you don't want it. I'll see if I can find the problem and repair it. I'm interested to know what the issue with it is

I know this is old, but did anything ever come of this? I would have loved to find out what happened with that old board and what the issue was.

Going through something similar now too, except mine isn't a mint new PSX. Just an old SCPH 1001
