#REPAIR

CD players are just rotting sorry for the bad news

[@inputerase]

To be honest, the laser is the last thing that needs replacing. 99% of the time it’s something different, like bad caps or the spindelmotor or mechanism needs attention. Also dust on the mirrors gives reading problems (in the laser unit) and needs some cleaning. The laser works or works not.

[@DaXande135]

How do I clean the inner parts of the laser unit the easiest way then? Seems not too easy to disassemble the whole pick up unit first...

[@donb5637]

Just because the caps are not bulging does not mean they are not leaky. I recapped a vincent cd player that was behaving similarly and it plays like new and completely trouble free after the new caps had about 100 hrs of time on them. Weird, but true. Good luck

I just bought a SONY CDP-CE 375 multidisk player for 20 euros, it was broken, I repaired it by spending 2 euros and 50 cents on a bag of elastic bands that took the place of the faulty belts, and it was like new again.

[@libertysurf06]

Before doing anything fancy, check the lens. Got the ‘No disc’ message on my good old Sony CD player, Unplugged the main power, all audio cables, unscrewed the hood, then applied a q-tip with windex on the laser lens. This fixed it, unexpectedly I must say!

[@kevindigo22]

Well that just ruined my day :( My newer CD player (RCA brand) just stopped reading CDs correctly, it will play about the first 3 tracks okay then hangs up. I have an old Sony CDP-CE275, must be at least 20 years old, and it won't play correctly. I think I will still take them apart and investigate. Considering that new music quality CD players start in the $400 to $500 range, I was hoping to get one of the old ones fixed. I remember the day when you could get a decent music quality CD player for not much more than $100, I am surprised at how expensive they are now.

[@spitsomefire]

they said the same thing about vinyl wouldn't be surprised if CDs make a comeback

[@darrenjukes8446]

Have you done any scope test, ie circuit diagram, or are they dead as well

[@disrealnow9664]

I have a Sony CDP-690 with exactly the same problem - the slightest tap or even walking across the room causes it to skip. And here is the thing - it is not the optical laser pickup unit, since I replaced it for a new one as this machine uses a KSS-210A which is still in production and relatively cheap. Made absolutely no difference, the machine is mega quick at reading both standard CD's and CDR's but this 'sensitivity' problem remains. I have cleaned it thoroughly, greased the cogs, the metal rail etc. - no change. Kind of running out of ideas what the problem could be.

[@brynshearwood9797]

I watch a video of a repair guy adjusting the gain pot and another pot and it solved this issue

[@DaXande135]

@@brynshearwood9797 It seems as if you need an Oscilloscope in order to properly adjust all the potentiometers that affect how the laser tracks the data from the CD. With a 210A you have 5 Potentiometers that you have to adjust, 4 of them are on the units mainboard and one is on the laser pickup itself.

[@alfdad4264]

my sony cd player has a screw on ther moter where you can adjust how hard it should hold the cd that worked for me

[@nicodenhaak3961]

The kss150 has a second lens which needs to be cleaned. After that the output will restore to former glory. The kss 210 replacement is junk, it doesn't have the second lens, which on the 150 protects the prisma inside from dirt.

[@radry100]

The repair the focking coils and magnet.

[@Daniel556]

The KSS-150A was made obsolete by the KSS-210A and the KSS-210A has new generic stock from china the differentce between the generic and original is the bushings are plastic and not brass buy they are the proper replacement imo and should be plug and play without needing an alignment.

[@qmaloney]

Yeah 100% I replaced mine with a generic KSS-212a (made in 2023). Works great.

[@v5e762]

There is nothing wrong with the laser. Just need to adjust the variable capacitors with a plastic pen cap like I did. Works like new now. Put in a cd and rotate the capacitor to one side till the cd makes funny noises and mark the spot. Rotate the other way till it makes funny noises or stops and mark the spot. Leave it half way between the two marks. Repeat for the other capacitors. It will run like new now!

[@DavidEhmCee]

oh that's interesting about the voice coils failing. I knew the laser diodes could get dim so I was expecting that

[@robertslater5706]

Hello i have a Sony model cdp 35. When I put the cd in it gets ejected after about 5 seconds. Any ideas???

[@hamesh3474]

Got to say that if you jar any disc player... It will skip... I have a fisher from 1986. . still using it today and honestly every day since 1986

[@drumsmoker731]

Man, I've got half a dozen players with various faults (laser, mechanics, ???) and now you reminding me that there are no more spare parts available, made me do a quick research on how much a brand new one costs nowadays (from a reputable brand). Well, where I live the cheapest one is a no frills Pioneer for €249!!! Think I will go with second hand ones till they're all dead and later resort to a few discmans I still got 🙄

[@jeff666p]

get a dvd or bluray player and hook up a external dac. it will sound as good or better. I bought 6 or so cd players sony ,kenwood ,teac and marantz. all failed within a year. got tired of wasting money on them.

[@cv507]

german amazon dude claimed soundwise ok (´more? or läss büt jäpp) skips öften etc..?

[@pooooya]

Hi man, I changed the laser pickup on my 95 Sony player but it still stops and errors after reading the disc for 30 s. Do you have any idea what else i can do? Thanks.

[@PiotrFicner]

You have some issue with a processor in 99%. But, only someone who knows what they're doing can help you ;).

[@spitsomefire]

had a quite a few Pioneer Cd Players had a PD4100 player that the laser went out on it and there was only 1 available in the whole world on ali express for 300$ insane

[@muhammad-bin-american]

A bit confusing but thanks for the heads up.

[@jmsjms296]

Thanks for the info!

[@johnwakefield3141]

I like it's f****d and it's all gone to s**t.

[@PiotrFicner]

I can still buy these lasers at ASWO shop, so, please don't say you can't buy it ;).

[@PiotrFicner]

ASWO shop has KSS210A which showing as equivilant to this one.

[@jamieblatantsparky]

They don’t work too well

[@PiotrFicner]

@@jamieblatantsparky yes, because you should calibrate it and not just replace it ;). Ideally use a service manual and an oscilloscope.

[@jamieblatantsparky]

@@PiotrFicner it’s because they are no longer made and what you but is 10 year old stock that’s been sitting on a shelf in a warehouse and is blackest from static

[@PiotrFicner]

@@jamieblatantsparky For now I have no complaints from my customers, and I received my laser yesterday from ASWO as well for CDP-M48 which I use it here. So, I'll install it and calibrate it, ane be the judge myself ;). When it comes to the capacitors, yes, electrolytic capacitors when lying too long can sometimes not deliver if kept for too long on the shelf, but I haven't seen a problem with a laser yet. Maybe I need to fix more than a few though to see what you see ;).

[@Blambik]

Why can't replace the laser head?

[@jamieblatantsparky]

Because you can’t bu any new heads that aren’t stock from a batch produced 20 years ago

[@Blambik]

@@jamieblatantsparky Last Year, I've bought KSS-210A, and replace it. It was newest. I guess this head isn't original but device works fine.

[@salaamallahalternatechannel]

MY UNITS STILL WORK FINE

[@pocketchanged]

I've got a number of old CDPs that work fine, it was interesting acquiring the knowledge to clean and adjust the lasers. I'd guess someone will start producing the necessary bits to keep these old players functioning, given time... BTW, these players (and yourself) were dying the moment you opened the carton... pc
