Picked up a Goodwill ps1 and it was taking a long-time reading disk. Adjusted to your readings and it works perfect :) thanks. Forgot to mention the original reading was .900 m ohms, turned screw left 1/16 and got a reading of 1.25 m ohms :)
just got this issue few days ago - game freeze and laser cannot read normal CD Audio discs. Lubricated rails and gears. Cleared lens with isoprop-alcohol. Fiddled with potentiometer on the foil. Sometimes laser makes loud noices then read CD Audio, but not original or burned disks. The model of PS1 is SCPH-7002 and laser model is KSM-440. Plastic rails wear over time, so further maintain is doomed. Considering the chinese clones are also faulty, I think it's time to switch to xStation or PSIO. They are quite expensive, and requier soldering skills. Wish me luck.
Yeah the xStation or PSIO is probably the way go. The plastic rails were a terrible design, I see so many of these consoles dying as a result off faulty lasers with no real solution to fix them.
As a retro guy who intends to keep a working PS1 around, I have to admit the truth. This particular machine seems to have a few rather serious manufacturing defects. 1. The plastic rails in the drive assemblies degrade. Some models don't have this problem, but it still affected quite a few units. 2. The spindle hubs are highly prone to breaking into pieces, which ruins disc playback over time. All ps1's are vulnerable to this. 3. The CD drive door mechanism does not fully press down on the "open/close" button for many models... and that also affects disc playback. The problem can arise at any time. Can't say I'm surprised by any of this though, as it's a Sony product, after all. 😒
I think in few years it will be hard to find PS1's that are still working. It's a shame as the PS1 is a console I have very fond memories of. Without a source of reliable new lasers I think a lot will end up running Xstation or something.
I bought from ebay as said new laser. But after some time it stopped working. So I measured and it showed 565. Do I bougth old laser which was adjusted to work for some time?
@@EasyConsoleFixes thank you for this video mate. I have a PAL SCPH1001 I’m only using it for music. Had some CD-Rs (and even a few commercial releases ) skipping. Last year I replaced the laser unit so I was surprised. On my aftermarket laser unit this pot is tiny and does not have a Philips head. It’s just a very small indented wheel with a groove. So I used a TINY flat screwdriver. My eyes are not great for this now as I’m in my 50s (geezer mode). Rotated it clockwise 1/8th and my CD-Rs are playing well so far. Many thanks 🙏.
@@brhodes0 The replacement laser units for these consoles seem to be very hit or miss which is a shame. Glad the video was able to help, it's nice to be able to keep these old consoles working.
Thank you very much for the video. My question is, how to place down the pinned outlet (which connects the laser unit to the board) as the pinned part came out and it no longer can stick down on its own onto the board, thanks for the answer.
Do you mean the white connector that the laser's ribbon cable connects into has come away from the board. If the board has not been damaged, soldering the connector back onto the board is the only way I can think of to fix this.
thank you for multimeter readings, just going in blind is a bad idea my 7002 playstation was on 800, i put it down to 700, it was a little better but still problematic, moved it to 623 and now it works, wonder how long it will last now. curious to what other peoples readings are and if you reply also mention your console revision thanks.
In my experience adjusting the pot is only ever a temporary fix, depending on use it may well last a long time but the fact the adjustment was needed means the laser is on the way out. Replacement laser assemblies seem to be a bit hit and miss with the quality so that's not a great solution either.
@@vilmantastamulenas4225 Did the replacement laser work at all or did it never work. Are you playing burned disc's on your console, this can be hard on the lasers.
Hi there, my Japanese PS1 is not reading games and I need a model I couldn't find anywhere on the market and on the internet. I need an optical laser lens replacement KSM-440ADM "03Y470 KB432". Where could I find it? They only propose to me "20617 WH392". My PS1 model is a 7000 SCPH, can I use a classic KSM-440ADM with 20617 WH392 to replace my optic laser lens? I'm kind of desperate of the situation.😞
Any of the KSM-440ADM lasers will work fine for you. Most of the PS1 lasers will work in any PS1, the only thing to look out for is the length of the ribbon cable, some of the consoles use a really long ribbon. But even then cable extenders are available.
Thanks. Like what you did, I decide to buy a KSM-440ADM, I hope it will fit for my PS1 and that it will work. I'm not an expert at all in electronics so I hope it will be good for me.@@EasyConsoleFixes
my ps can read almost any cd., but is always laggy. the lagging can only be fixed when i put the ps on 45 degree angle. its kinda annoying, id say. is this vid related to my problem?
If the console is working better at a 45 degree angle or upside down, its normally caused by wear to the plastic the laser runs up and down on. Why Sony made these out of plastic who knows. Gravity helps fix this when the console is upside down. Sometimes lubricating the parts the laser runs on helps put not always.
I went clockwise 1/8 turn, didnt work. Went another 1/8 and it worked! Just got my 24 year old ps1 from my parents storage and brought it back to life! Thanks!
My case is like that: 1.2KOhm can not read discs. After regulation I could get black PS logo screen on values 0.91kOhm but still no progress. Is it means that laser is burn out?
Hi, if you can't get the laser to work after adjusting the potentiometer the laser has probably died. Normally when you start having to adjust the potentiometer it means the laser has started to fail.
Hi, unfortunately there is no way to know how long it will last but if you need to adjust the laser it has already starting dying. Adjusting the pot just makes the console work a bit longer. It's a shame the replacement laser assemblies for the PS1 seem to be very hit and miss as it means there is no reliable way to keep these consoles working.
Hi I have a ps1 console that it won't read discs until I push the right upper corner of the console case ! Why ? Also it works with this way when I open it, then I push that small piece at the corner ! Any idea how to fix it and works normal without pushing !
The switch that detects the console lid is closed is towards the right back corner. Its near the right lid hinge when the lid is open. Is it possible there is an issue with the switch, you could try pushing it down manually with the lid open to see if the console starts reading the disc.
@@EasyConsoleFixes yes , I did pushing it while the lid was open and yeah it works fine. But once I closed it, the disc never moved ! It looks like it needs something heavy above the lid or pushing then it works with closed lid .
@@momoqahtani6545 That's good, the switch works fine then. The spike in the lid or the little grey button when the lid is open is not pushing the little black lever on the circuit board correctly.
@@EasyConsoleFixes I was thinking of taping a small piece of tissue on it so when I closed lid , it worked fine ! I don't know why it happened like that suddenly.
What does it mean if my disc spins better after this but it suddenly stops after a few seconds? There are also cases that it doesn't stop but the disc just spins slower. I need to press the sensor again so it spins again. Thanks!
Unfortunately this sounds like the laser is still not able to read the disc. If you mean the lid sensor, this just makes the console think the lid has been opened and closed so it tries to read the disc again.
The increased voltage increases the intensity of the laser. It's worth noting that in my experience its only ever a temporary fix. The reason you have to do is because the laser is dying, this just gets you some more use out of it. I wouldn't make any adjustments to a console is still reading discs. In most consoles I would recommended changing the laser but the replacements for the PS1 are nearly as much as a replacement console.
@03Lorac did you try replacing the capacitors? It could be the capacitors. I once replaced the disk laser, but that wasn't the issue. It was rather the capacitors. Once I replaced the capacitors, everything worked properly again.
@@RaffaelloLorenzusSayde no i gave up on it and am playing the games via emulator. There's simply no logical justification to invest further into the console.
If a console is not reading disc's cleaning the laser lens should always be the first thing attempted. Adjusting the potentiometers is really a last resort as it means the laser is dying and you are just prolonging its life.
i have bought 2 new cd assembly for my ps1 but the same problem still happens the disc spins for a moment, then stops. on every cd assembly what could be the problem? Power supply maybe?
Now I couldn't tell you where I've seen this information, but the problem could lie in the actual motor that makes the disc spin. A replacement shouldn't be very expensive, but you'll need to find one that's exactly the same. However, the issue could also be with the lens. Depending on your budget, skill, and compatibility, you could install an xstation or a PSIO, but that's up to you
If you push the laser away from the spindle motor and turn the console on a hold down the button at the back of the console that detects the lid is closed does the laser move back to the middle or and does the lens try and focus by moving up and down. Normally the the console stops spinning because it doesn't see a disc. I wonder is there an issue with your console board that its powering the spindle motor but not the laser or worm gear.
@Kubanb3 It does seem like the laser is not able to read the disc's. A new Laser assembly (unfortunately these can be hit or miss) or adjusting the laser as in the video are probably your only solution. Adjusting the laser will get you more time out of your current laser but it normally only buys more time as the laser has started to fail.
@Kubanb3 No the spindle should be fine, If you hold the lid closed switch down with no disc in the console you will see the spindle do the same stop start as the console sees no disc.
@@EasyConsoleFixeshaving this issue with mine. Disc gets spun once then once more and then naturally comes to a halt, without the disc the spindle will spin once the laser will dip down then back up spindle will spin once more and the laser will dip down again and then the laser turns off. No discs being read. So adjust or new laser time?
These PS1's had a design flaw, the laser moves backwards and forwards on plastic guides. Unfortunately these wear out over time. When you put it upside down or on its side gravity puts the laser back in its correct position. Sometimes lubricating the moving parts of the laser assembly helps but there is no real permanent fix other than a new laser assembly.
