Sony PlayStation Disc Skipping Issues

Sony PlayStation Disc Skipping Issues - Retro Console Repair

3 жыл бұрын

In this video I work on an original Sony PlayStation that has FMV (Full Motion Video) skipping issues. This is a North American launch model SCPH-1001 that has the RCA jacks on the back in addition to the proprietary Multi-Out connector. Sony discontinued the RCA jacks on the SCPH-550X models and these units have become somewhat desirable from a collectibility standpoint.
The launch model PlayStations were notorious for having issues with the optical drive. The drives were made almost entirely of plastic and components would degrade due to friction. There is also documentation of warping due to the close proximity to the power supply which added heat to the equation and made things even worse. As a result these consoles would start to have difficulty readings discs. This often manifested in FMV during game intros and in-game sequences being choppy, and eventually causing crashes before not reading discs at all.
In this repair I go through the normal steps I normally would to refurbish an optical drive, which includes cleaning the laser and re-lubricating all the moving parts with lithium grease, followed by calibrating the laser to make sure it is within specifications. In addition to the regular laser intensity adjustment, the launch model PlayStations have manual controls for "Bias" and "Gain" to further tune the laser assembly, although this was automated in later revisions.
After all the above fails, I eventually manage to recover the drive by gluing a thin piece of aluminum stock to compensate for the missing material in the drive. This seemed to restore the drive and bring it back into alignment. While I am unsure of the longevity of this repair, it was a great learning experience to repair this console and learn about its design flaws.

For those who are still stumped, I've been able to revive drives by cleaning and oiling the drive motor spindle. Underneath the motor is two small holes, and I pour isopropyl alcohol into the roles, rotate the spindle a bit, then give it time to completely dry. Then I add mechanical oil (lighter than the lithium grease used on the sled) into the holes to lubricate the motor. After many years the disc drives will spin fast, but not always at the perfect speed needed to read discs without stuttering.

The leveling makes so much sense considering people would "level" their systems by putting it upside down. It was an alignment issue

@huldu Жыл бұрын

It was such a weird thing to even come up with as a kid. Nobody told me to do it. I must have thought it was something with the laser not "reaching" the disc or something silly like that which made me flip the console upside and - and it worked. Eventually I sold the console but I did the console flipping for quite a while. I'm sure eventually it would have stopped working or maybe not.

Wow, awesome repair. Every cause I've heard about the FMV's skipping on original launch model PS1's were all about the laser being heated and cooked from being placed on the left side of the unit close to the power supply. Apparently it was the plastic sled assembly being worn down instead. This explains why turning the console upside-down would alleviate the problem by allowing gravity to drop the laser sled closer to the disc.

My model has auto gain + bias so no pots for that, just laser power on the drive. There is one pot on the MB for a push-pull adjustment but I can't see any affect at all when I tweak that one.

@Naitoraven951 2 жыл бұрын

Nice video :) ! But, I'll give you some tips about the SCPH-100x and ABM/AAM/ACM laser class. First of all, check F.BIAS/GAIN voltages from CL708 is useless. All you need is a oscilloscope and check the RF SIGNAL. The main reason of F.BIAS pot presence on the motherboard is to facilitate the servo on the reading (focus operation). Move forward or back and obtain the best RF signal possibile (no jitter and with a stable RF envelope). After that, move the laser pot forward to obtain 1.2v p-p with an original disc (music disc work too). The GAIN is impossible to adjust :). Is used to trace and seek the sequential data pits on the disc. F.GAIN HIGH = Laser coil very noisy and sensible to shock movement. F.GAIN LOW= no reading. Try to find the best position when hitting GENTLY the console (I'm not kidding). If the laser doesnt' skip, that' a decent F.GAIN calibration. Also, you have to lubrifcate motor spindle and motor sled. -From an huge PS1 lover! P.S That metal rail is very nice!!

@powerzx 3 жыл бұрын

Good job. Again my 3 cents :) 1)Sometimes problem is not in worn plastic parts, but in the laser coils. It is good practice to check laser coils first. Left and right coils should have the same resistance from 5 Ohms in used lasers to 6.2 Ohms in new lasers (higher value is better). I gave those numbres from my memory, about 20 years passed since I worked with PSX consoles, so values may not be exact and may vary depending on laser model. 2)I would use less grease, like 1/3 or even 1/4 of what you used. 3)Before you make any changes to resistor pots check their resistance value with multimeter and write it down. Check resistors when console is unplugged from power. Avoid touching to moving part of the variable resistor or you can change resistance. Check resistance between two pins of the variable resistor. Only make changes to resistor pot on the laser (when console is not powered on and change resistance very little). Setting wrong value for variable resistor on laser means that you can deliver too much power to emiter and you will destory it, so make very small changes to check the difference.

Good luck with those reproduction lasers. In my experience, they are garbage, more often than not. I tossed one of these 1001 models out of frustration about a year ago. The original laser was junk, and even after resorting to using a 101 laser with the ACM cover (to properly fit inside of the 1001), I often had to prop it on its side or upside down, which was no better than the tricks people usually employ with one of these consoles anyway. That comment about those pots being finicky is NO JOKE. 😒 Anyway, great video, and I hope it saves other 1001 models. At least I have two 7501's in really good shape that have proven to be pretty reliable.

@BorderlineOCD 3 жыл бұрын

I've heard similar things about those lasers, but figured it was worth a shot. I bought them from two different sellers just to get a different supply (although I'm sure they're all made by the same factory). I'm curious about how well calibrated those drives are, and if perhaps a bit of fine tuning and some quality lube would improve the odds of them lasting any longer. I guess I'll find out.

@unchi1999 Жыл бұрын

IKR? The real reason why i also threw these 1001 models out of frustration is because not only do the cutscenes skip, sometimes you’ll hear really unpleasant noises coming from the CD drive and starts spinning the disc abnoramlly fast to the point where it just hangs on the ps1 logo. So yeah, These 1001 models so are ridiculously annoying!

A stray wire pushed up against the disk from the underside and dug a slight groove into the disk... Double fail .... Basically I got to the point of adjusting the Pots and gave up out of frustration in ruining the disk. I probably still have it in storage....

So, not only does the angle of the console affect a worn sled, it can also affect a worn spindle.

For calibrating these properly you need to achieve a coherent eye pattern using an oscilloscope on the laser test point. Arbitrary voltage values might get you close but not quite. The shim likely moved the laser and improved the eye pattern. The pots do the same thing but you can't see the result because you're not using an oscilloscope to verify that there's a solid eye pattern. Pretty cool workaround though.

Hey Borderline OCD for the PS1 you repaired using the original drive if it starts to have skipping issues again after a while use a KSM 440 BAM laser instead the laser used for a slim Ps One just you will need to swap out the top covers for the case top case to fit correctly or else it will not fit properly and a tip is use like a teflon grease not spray but grease will work better in keeping it lubbed better in the long term

the power supply was the issue where heat would warp the laser lens. in other revisions of the PlayStation, Sony moved the position of the laser to the right side to reduce heat

FYi that potentiometer on tthe PSU adjusts the System wide voltage. Someone might have tweaked that too causing the bias voltage to be slightly off

That was fascinating. I recommend just getting the 9000 series, it doesn't have any of these issues

I did the same with my 1001, but for me with an aftermarket optical drive I had this parameters, Bias 1.7v - Laser 12.3mv and Gain 1.73v.

This ones that you buy from China you may have to fix them also, i've bought one that i've had to adjust the height of the spindle, and clean even the mirror of the laser and the lens above and underneath and also the glass of the diode, it was very dirty, but it was of great built quality, actually a much better unit than the previous one that i've bought from China, that the spindle hat came of just from regular usage and the plastic detachable rail came very loose from design it seems, and it's clearly very inferior in built quality. So, i really think you should try to fix the original ones. Congratulations from the great work made on this one, very cool!

Nice video, although considering it's made out of plastic, at this point, I'd rather go with a 440BAM pickup. It seems to adapt WAY better to the 100x in terms of reliability, to the point where it's almost plug'n play.
