This unit uses the KHM 230AAA pickup, no longer made by Sony but you can find Chinese made replacements for about $60.00. But they require calibration, there are two small pots on the pickup (one for SACD, one for CD) that need to be adjusted in order to get the pickup to read discs. When Sony sold the replacement parts, they came fully calibrated and it was a simple drop in replacement. I've replaced a few in my player. They tend to last about three years, then develop the problem of not reading the SACD layer. You can see by the easy access to replace the pickup that Sony must have know that the lasers would be short lived. But they are great sounding units and worth trying to save.

I have 2 used Sony SACD carousel players similar to this model. They both have the same problem. They both worked fine but over time they stopped reading the SACD layer. I found the Sony service manual and it said to check 2 specific resistors. I brought it to an audio engineer friend and he replaced the resistors on one of my players and after running the diagnostic self test as instructed by the service manual, it worked again.... but only for a few days and then stopped reading the SACD layers again. So we agreed it was the laser pickup. I have seen other CD repair videos that had trouble reading discs and those carousel players had mini adjustment pots to increase the laser. I haven't attempted to see if my players have this adjustment pot. I managed to find a 100 disc SONY DVD/SACD player so I'm able to enjoy my SACDs again. However, it was also used and 2 days after I started using it, the belts gave out. Luckily there were a few videos on youtube with similar Sony model players and my son and I were able to replace the belts in 20mins with belts from our bag of assorted belts. I love SACDs but all players I have are VERY SLOW to read discs and tell me if it's a SACD or CD. It is different when i put in a pure SACD (NON HYBRID). Those discs are ONLY playable on SACD players and they load and read much faster than hybrid discs.

There is a auto calibration menu you can enter to automatically adjust the SACD layer on the DVP S900v. Same as the DVP s9000.

It seems to be a common problem with those players. I have a Sony SCD XB790QS and a DVP-NS900QS, both which should read SACD, but both aren't able to do so anymore. I had also a DVP-NS930QS with this issue. Also i found another models online for sale which also can't read the SACD layer anymore. The SACD doesn't give the added value to the customer as the CD to the LP. The SACD adresses only a friction of the market, the audiophiles and the surround sound listeners, but the benefit for the normal stereo listener is subtle (if there is one). Then to invest another $$$ for the hardware and buy the music again on SACD which is already bought in the past doesn't make much sense.

The junk audio you are seeing above 20kHz is the result of noise shaping. DSD, the encoding (not sampling there is no sampling) format used by SACD uses a 1 bit stream, this results on a quantisation error/noise that is pushed up into the ultrasonics using noise shaping. CD's do much the same, they also can use noise shaping to increase the dynamic range by pushing the noise up above 20kHz or so where the filters (and the human ear) filter it out. Here however it looks like its not being filtered out at all leaving your amp to pump the noise to the tweeters. This is one of the things I tell audiophiles when they claim that SACD is superior to CD and that it makes a difference. Well it is superior, but it makes no difference apart from potentially damaging your equipment and being an attempt to combat CD ripping.

Sony! Yes! 👍 Interesting video. Never had those either. Personally, I tire of having to buy upgraded equipment and media, buying the same movies, the same music because a "new improved version" came out. I am satisfied with DVD's and Blu-Ray. I am satisfied with audio CD's. My senses are not as acute as they used to be. Especially my hearing. High frequencies over 8-10 khz. is the highest I can hear now. My eyes are not perfect, but can still pass the vision tests at TBE DMV. I know, I'm going on.... Lol.

The noise might be some caps on the codec board. 6:56 on the left side of the cap you are measuring, that brown block is also an SMD electrolytic, a very prone to failure type. I would have cleaned the lens. I've seen many examples with DVD players when it was able to read only one type of disc, either CD or DVD, but after cleaning the lens, it was reading fine both types. I used to clean the lens with a cotton swab, wetted with window cleaner (diluted to 50% with distilled water to be safe). The lens can have some haze on it that a dry cotton swab can not remove. Sometimes this haze appears on the inner side of the lens as well, that's bad news. I was able to repair only one from like 10 by disassembling and cleaning the inner side of the lens, and the mirrors/prisms whatnots that I could access under the lens. The other 90% of them either had other problems apart from the haze, and/or disassembling the pickup skewed some critical optical adjustments.

Looks like what we used to call “popcorn noise”. Oscillation internal to a integrated circuit. Chase could be coming in on the 1st stage from the pickup.

Different formats are very often or almost guaranteed to be compressed differently with respect to dynamic range BEFORE it even gets to the physical media. And then once you consider the spec differences in relation to that - it is within the realm of possibility that it isn't the player causing the fault. I do see and understand how it actually is technically possible that it is, though. In other words, the producers of the disc could have considered none of it a fault in the first place.

Dsd audio and thus sacd had a small resergence in the early 2010s before streaming services started hosting higher bitrate and some hosting ac3 music. I wonder if that audio burst has something to do with the system trying to throw out dsd copy protection auth maybe? I vaguely reading something about them throwing noise at high frequency to tell capable receiver to run at a higher bitrate and to authenticate dsd data stream, I could also be getting confused with a military communication standard however as they both use very very similar technology.

Finding the lasers can be expensive and they often don't work even Sony warns about this, There are a lot of lovely players out there that are just door stops now no lasers and they always seem to die. SACD is really big in Japan with new releases all the time. I use a Blu ray player and rip my discs to a computer. I wonder if the brick filter is playing up.

I mean, let's be honest, the real reason SACD never caught on was both because sigma-delta encoding on DSD offered no noticeable audible benefit over CD to the average consumer and nobody wants to pay even more for the same music they already owned on CD.

The main advantage is a considerable pool of meticulously mastered releases and the simplicity of 1bit/2.8MHz decoding process in proprietary chips- you either have a 1 or 0, full or no voltage and no need to calculate the value as in multibit D/A.

@@paulb4661 > no voltage and no need to calculate the value as in multibit D/A CD player DAC's havnt done that since the 90's. They like all other devices use a 1 bit DAC, basically they multisample and convert the PCM into a bitstream then feed it to a 1 bit DAC just like DSD does. There can only be a difference with the mastering as DSD could be used to record the original source and the mastering will be intended for audiophiles so they would avoid messing with the audio, its not aimed at people plaing in their cars for example. Oh and obviously the surround sound.
