Clownstyle Posted August 13, 2020 Share Posted August 13, 2020 I still have a CDX in the loft which seems to be in a non-working state. Last I remember I drunkely switched the red switch on the back that goes between different voltages (still to this day do not realise why I did that) so possibly something fried. It still spins around but alas there is no sound. Maybe I'll dig it out and check. Did this project go anywhere or is it now scrapped - Sorry skipped a few pages Quote Link to comment Share on other sites More sharing options...
flo86 Posted August 30, 2020 Share Posted August 30, 2020 just gotted a dead Numark CDX and started do disasamble it and attempt to fix it and I have some impressions. The specs for this tool are/was OK but it is a low cost build. They didn't use, for example, quality capacitors and for this reason, after a period of time, some of them are shorting some circuits. In my CDX I found a IC Stabiliser exploded, a rectifier and a NPN tranzistor and, the laser unit. I replaced all of these and it works but sometimes it skips OEM CD. I tried to replace only the laser, and it didn't worked, I bought a new OEM laser unit with the Servo motors and it worked but hardly, and the reason for this is that the laser (Kss213c)that I bought from internet wasn't a OEM part. After that, I went to a scrap center and bought from there a micro Hi Fi system, A Grunding Cirflex, and a Sony cd player CDP Xe200 which uses the same laser as CDX use but . I swamped the LSU unit and now, the CDX works fine and I made that choice because that was the only way to get a working original Sony laser. The other problem is that, the supply voltage for this player is not well filtered, and this causes some freezing of the unit, some "auto cue" because when it skips the disc, it will replay a randomly part of the song until the lens gets on the CD track again and will continue to play from where it was "stuck". I will try with an oscilo in the future to diagnose the unit and I will tell you what to check in case you need to repair these units. Also, similar hardware you will find also in other brands equipment. Quote Link to comment Share on other sites More sharing options...
Mutis Mayfield Posted September 19, 2020 Share Posted September 19, 2020 Hi,I visit very rarely the forum but I dig into the old copy of the drive I had and found some documents from diverse sources (Rasteri being one of them) about the CDX. https://www.dropbox.com/s/003l82tra216j9x/cdx.zip?dl=0 I uploaded to dropbox so anyone can download them.Hope it helps. -m!

alexinc Posted March 8, 2021 Share Posted March 8, 2021 When i came across this post i was so excited to bring new life into my CDXs, as it's still way more fun playing them out instead of beat matching with pioneer gear... 😉 Thanks to milo i now know how to maintenance the motor and while doing this i'm planning on swapping the cd drive cable by soldering the scsci cable directly to the mainboard. Does it really solve the CD slot issues with CD in / CD out reliable? I mean is it noticeable doing this extra work to the devices? Back in the days i did the tape fix, but still have fluky drives from time to time... What i'm even more interested in is, if someone ever tried to replace the cd drive with those scsi hard drive emulator mentioned in here earlier? Maybe it would also be possible to add HDX prepared hdd instead of cd drive and the upgrade to hdx firmware somehow? i know it's most probably wishful thinking, as hdx firmware may check for other components besides hdx prepared hdd...

Mutis Mayfield Posted March 8, 2021 Share Posted March 8, 2021 It could be easier to adapt the Sc1000 hardware into it IMHO. Quote Link to comment Share on other sites More sharing options...
moonraker Posted March 22, 2021 Share Posted March 22, 2021 Hey guys, what about the HDX ? isnt that just running an IDE drive plugged into the same plug as the CD drive, can we load a HDX firmware and plug an ide to sd adapter? and have mp3s on the sd card Quote Link to comment Share on other sites More sharing options...
Mutis Mayfield Posted March 25, 2021 Share Posted March 25, 2021 It lacks some components but maybe it could work. Service manual is out there at links so take a look by yourself if you want to explore that route but IMO it will be easier to adapt SC1000 as I said in my previous post.

BassCrime Posted March 3, 2022 Share Posted March 3, 2022 Hello, I'm new to the forum and I've been fascinated by the interest in this wonderful player. If I can help you, do not hesitate to ask me. I have a problem with the reader that when I insert the cd it automatically ejects it without stopping to read it and I don't know what it could be. The idea of being able to convert it to read usb and hdd is a fascinating idea. Quote Link to comment Share on other sites More sharing options...

BassCrime Posted March 4, 2022 Share Posted March 4, 2022 I have a broken mini limit switch and I can't find one like it anywhere to buy them. Can you help me? Do you know the model of these limit switches? Quote Link to comment Share on other sites More sharing options...
BassCrime Posted March 7, 2022 Share Posted March 7, 2022 I solved this problem with the limit switch and now it reads the cdx without problems... but when I place the reader on the support to insert it into the cdx it ejects the cds. The only way to place it so that it reads the cds is without the support. When it has the support it ejects the cds and it doesn't have the strength to insert them all and when I remove it it works perfectly. Has anyone had this problem?

alexinc Posted April 6, 2022 Share Posted April 6, 2022 Awesome! Curious, as i just modded my devices replacing the whole cd drive connection with just the centronics cable to make the whole drive (especially searching in tracks) more stable and clean up/oil spindles. Btw you need more than one centronics cable to get all pins and bridges connected! Would love to finally add usb/sdcard support. Quote Link to comment Share on other sites More sharing options...
Coprine Posted November 21, 2022 Share Posted November 21, 2022 Hi all, last week i bought a CDX 90 and i'm curious whether it has the latest update. When i look at the utility version screen it says "C10.B58.S32.M14.P01". I don't know if this is a software version or something else. Can you help me out?

Lou Posted March 30, 2023 Share Posted March 30, 2023 I have 2 cdx players. Both work but one has sticky start stop buttons and the other one is a little stiff when trying to scratch. Any ideas on how to clean the switches? I’m not a tech person so I’ll consider letting them go. I have an idj2 that I’m more partial to. I’m in AZ if anyone is interested.

tearoam Posted May 27, 2023 Share Posted May 27, 2023 Hello. Ive been fixated on the motorized platter and have since restored several SLDZ1200's and not Ive gotten a hold of three CDX's and wondering if and why i should be on the latest and also if anyone can share a copy of the firmware that'd be dope. so i figured out that cd drive problem is at least for mine is the motors not being able to spin up to read and so regreasing them was all i had to do on mine. and pro tips for running these are appreciated. all the best yall Quote Link to comment Share on other sites More sharing options...
