The PlayStation that just needed a cotton swab
Sold as "doesn't recognize discs", this SCPH-9001 booted every game I put in it. A slightly slow audio CD, one pass over the lens and a soapy bath later, it's back in service.
Before
After
This one came in a pair. A seller in Langley, BC had two PlayStations listed for parts, so I took both with combined shipping. The listing for this one said exactly this: "system is for parts/repair, doesn't recognize disks". No cables, no controller, just the console.
The SCPH-9001 is the last of the big grey PlayStations, from 1999. Sony had dropped the parallel port on the back by then, but it also has the newest laser of the whole fat-PS1 line, and those hold up better than the early ones. "Doesn't read discs" is the number one complaint on a PS1 this age, and it can mean anything from a fingerprint on the lens to a laser that's done. At C$37.50 landed, I figured the odds were worth it.
First test, before touching anything
The PSone taught me to test a console before touching anything, and I haven't skipped that step since. So: figure-8 power cord, composite cable, a controller, and the discs I test every PlayStation with.
An audio CD first, because the CD player screen is the gentlest thing a PS1 can do. It played. Loading felt a bit slow, a second or two of hesitation before the track list came up, but it played. Then Legend of Dragoon. It booted, ran, and looked great. Then Final Fantasy IX, and I loaded a save from my memory card to check the card slots while I was at it. Both slots fine, game fine.
So far, the only thing wrong with a console sold as "doesn't recognize discs" was a slightly slow audio CD. I have no idea what the seller tested with. Maybe a scratched disc, maybe a burned one, maybe a lens that was worse for them than it was for me. The listing was honest about what they saw. It just wasn't what I saw.
Cleaning the lens
A slow audio CD is still a hint. The laser has to find the disc's table of contents before anything happens, and a dusty lens makes that search longer. So I did the cheapest fix there is: a cotton swab, a bit of isopropyl alcohol, and one gentle pass over the lens with the lid open. No pressure. The lens sits on a little suspension and doesn't like being pushed.
Then the audio CD again. It loaded like a normal PS1 this time, no hesitation. I also put in my good old Final Fantasy Tactics, a game I love, and it played without a stutter.
Opening it up
With the drive behaving, the rest of the job was cosmetic, and this shell needed it. Yellowed, grimy in the seams, and a dark rectangle of sticker residue on the lid. Six Phillips screws on the bottom and the top shell lifts straight off. Nothing is glued on a PS1.
Inside was a surprise: clean. Not spotless, but nowhere near what the outside suggested. The drive, the power supply, the ribbon cables, all fine.
I pulled the mainboard out to look at both sides. It's a PU-23 board, the revision you expect in a 9001. The top was very clean. The back had a few small dull spots where something had dried, minor stuff. The power board on the side was the same story: a little dusty, nothing worrying.
The bath
Boards first: isopropyl alcohol on both sides, then a proper dry. The back came out looking like it left the factory.
Then the shell. Every plastic part went into hot water with Dawn dish soap. Not boiling, just hot tap water. A good soak, a rinse, and everything laid out to dry completely. The sticker residue came off in the same bath. The yellowing didn't, because soap doesn't fix that. That's a retrobrighting job for another day, if I ever bother.
Back together
Everything went back in the order it came out. Screws in, power on, disc in. Perfect.
So the verdict on a console sold as not recognizing discs: a dirty lens and a dirty shell. Zero parts, one cotton swab, and a very long-lived little machine that now reads everything I own. It's going up for sale, and like every console on this blog, whatever it makes goes into the Japan fund.
