Jukebox CD Player Repair

[@robertkiss5461]

Sir, God bless you for this video! You helped me a lot to repair a Philips CD753 for a friend. I have a masters degree in electronics, but it was 35 years ago! Your equipment is a dream for any hardware-software Specialist. I used to write some computer drivers, so you know what is it about. I just wanted to show myself, that I can still do it. But for now, I realized, that never ever again! I do not have the eyes for this anymore. But your video made it possible! Thanks a lot and greetings from Vienna!

[@Mandylove999]

Completely over my head and not in my skill set but absolutely addicted to watching

[@S-Theo]

I'm full of admiration for this guy

[@andrewdolinskiatcarpathian]

Watching Mark is pure joy. Such infectious enthusiasm. 👏👏👍😀

[@shaunmorrissey7313]

Nice repair, that Arduino library is genius, there are some very clever folk around.

[@petehillyer5444]

Yes certainly is. I made use of the Library for an "all in one" test rig specifically for these players

[@iantyler4045]

Great video. Having the Arduino rig to test really takes the guesswork out of it. I particularly like the CD on the icy pole stick test.

[@herbertmathews]

Hi Mark, enjoy the videos very much, i do the same thing but just as a hobby. Im about 4 miles away from you. I mainly do cassette decks.

[@wildfrank]

Mark, you make it all so simple, you are a real diagnostician and a craftsman, totally competent!!!

[@ralphf8951]

PhD knowledge of electronics! Genius! Thanks for these wonderful videos. Please keep them going.

[@Wurlyscope]

You are an amazing technician, thank’s for another great video!

[@johnwright8814]

This takes me back I used to repair CD jukeboxes 30 odd years ago, which used the Philips swing-arm pickups, the CDM-4, rather than the sled. There were no Arduinos back then, but we had a stripped down player for testing, and a laser power meter to check the laser.

[@hadibq]

That's a nice SDA script to read!! Thanks Mark for sharing!

[@gargunza4141]

Love your videos Mark, as Brucie used to say, "You're my favourite"!

[@King_Henry]

You are brilliant. Only thing you didn’t do is play your own CD Phill Collins! 😂. I’m about to rebuild or replace my CD Pro. Brilliant video mate!!!

[@djfromage]

I once replaced a whole CD drive unit in a mini jukebox, as the difference in cost between the laser assembly and the whole thing was negligible. I powered it up, and nothing! I later chatted to a colleague who asked "did you remove the short across the laser?" Sure enough when I returned home and checked, there were a couple of pads near the laser that were bridged with a blob of solder. I removed it and it worked perfectly.

[@matthewseymour8972]

Many mobile phone rear cameras have IR filtering these days, but the front camera tends not to. I always used that trick when checking fibre optic cables.

[@gravyblue]

And if remote controls are working.

[@zimbab5748]

Superb Mark. Thank you for sharing that.

[@johnmarchington3146]

Another excellent video, Mark

[@mikem9403]

Impressive! I look forward to your videos.

[@MichaelCowden]

Would love to have seen the laser output from the phone camera. Thanks for another great video!

[@piwex69]

After watching this I’ve learnt there was a control protocol. It is never too late.

[@SimonWallwork]

You are a bloody genius.

[@claretlover1]

Pure genius.

[@grave8digger8]

Great repair and a very good CD :)

[@AllenCavedo]

Brilliant repair!

[@mikemattingly2859]

Excellent job!

[@petehillyer5444]

Hi Mark. Love your videos. So you understand the DSA Protocol now? :). LOts of good information out there. I am a jukebox repairer myself. And have done a lot of these players as well holding a little stock of CDM12, Pro and Pro2 players. I actually build and sell a complete test rig for these players, have sold all around the globe to the jukebox fraternity. Based on Arduino, but with built in display, push buttons and 5 / 9V regulators too. Just needs a set of powered speakers and a regulated 12V power adaptor or bench PSU. Wanted to show you here. But cant attach images sadly.Keep up the great videos.

[@mikedariabaab1821]

Pete, do you sell CDM12's? Looking to replace the one in my Wurlitzer Rainbow Jukebox.

[@petehillyer5444]

@@mikedariabaab1821 I have a very limited supply. But would would prefer if yours can be repaired. If you are in the UK. I could help, but feel since this is Marks video, it is a little unfair to hijack it. I can repair these, I do quite a few, which is why I developed an all in one test unit.

[@TheTomfortune]

@@petehillyer5444 Hi Pete, how much do you sell the all in one test units for?

[@S-Theo]

I wonder if you can help me to fix my tape cd recorder combo. Tape side is OK there is some issue with CD. I already asked like 100 people and no1 was able to help me. Its Tascam CC 222 with CD slot loading mechanism.

[@jimp3975]

I would like to buy your test fixture for players

[@jasonsomerville2504]

Back in the day, I used to use little light sensitive sensor circuits built into a pen to test these lasers and for also checking TV / hifi infra red remote controls etc

[@schummiehugo]

ant a nice repair good job happyman !

[@reparadiohifivintage]

Magnifico vídeo , saludos

[@tomharris1457]

Damn, you are GOOD.

[@Jammerk40]

Nice repair Mark!

[@bridlingtonrcbashers9230]

Used to fit these on Nsm jukebox’s 20 years ago

[@andybbeck2043]

super channel mark

[@sermaximum]

Hola, tengo una ROWE AMI starlight con cargador de 100cd. me falta el lector de cd, Philips cd pro. sabrías donde puedo conseguir uno ? gracias

[@misterbonzoid5623]

The linear sleds failed in the early days so the juke boxes skipped. We replaced scores of brand new units out on sites in NSM juke boxes for a company in Twickenham in the late 90s. A modification kit was sent out so the thousands sitting in workshops could be repaired and used, as they were brand new and £400 at the time. Also the idea that CD lasers wouldn't age like styli because no friction was rubbish. In the worst of them a feedback loop kept increasing the transmitter diode current to maintain sufficient receiver diode current in the optics until the heat killed the laser. That's what's happened here. The Philips CDM 4/36 was the best, with radial tracking. We had one on a site for ten years before it needed servicing.

[@df18001]

I used to work there at Twickenham - one of my first jobs was aligning the lasers on these CDM units using a glass disc and an anglepoise to project a cross!

[@codebeat4192]

That is really cool. I wonder if this method can be used for Technics-Panasonic players or replace the mechanisms with a Philips and an Arduino to bring the CD functionality back to life.

[@JamesBryant-h2t]

Any information on my NSM digital thunder cd player

[@johnvienta7622]

Hello Mark.... Would you like to have a go at the laser pick up for a Pioneer P-D70 CD player. I am in Australia and coming over to England in a few weeks and could bring it with me, not the whole player though as it weighs about 10kg. I have been told that it is a hard to find 1984 model and very difficult or impossible to get the laser parts here. I have sent you an email with photos of the unit.

[@Naitoraven951]

Those lasers are called Philips LDGU (Laser Diode Grating Unit). The main feature is, on the main package, we have diode emitter, diode receiver, and prism. They are all terrible and cheaply made. I've to say, that diagnostic mode is amazing!

[@tarasian666]

And people and companies are still making hi-end cd player of these units...

[@bpshyk]

Lol, of course he plays the Stones and start me up!!! Mark, I want to hit the pub with you!!!

[@eileensmyth6284]

Hi. not sure you can help me out I have a Wizard wall mounted cd Juke box it is quite old. and now and getting credit error singe. I do not know the code to cancel this . would you know where I could get it. thank you in advance.

[@graceeind]

Hi Mark where can I find info about the interface board you made to communicate to the player from your PC? Can I buy that and the interface ? I am fascinated and want to learn more about those players. Thank you.

[@cmonkey63]

It's always the laser when there's a problem. Reminds me of my first cdrom burner from the late 1990s. I was an early adopter, and the blank disks were expensive, like $3 each. Lost every second disc. 11 months into the warranty, turned out the laser was faulty from the factory. Replacement unit worked fine for years.

[@ToddSauve]

We had a CD player in the mid 1980s. The laser died after a few years and the repair shop told us they could not replace it. Said it was built that way and it was cheaper to buy a new CD player. The beginning of the throwaway electronics age--which I hate!

[@kerrygleeson4409]

Thanks for sharing your amazing knowledge so interesting 🦘

[@awaazhoosein6565]

Love ur video

[@exxosuk]

Wow I used to service those from jukeboxes and those lasers were always failing. Can't beat the old CDM12 :)

[@doubleslit9513]

No $#!t? You rock! 🙏

[@neilb6473]

hi, please send a link if possible for the replacement laser, that's what I need..

[@johnwakefield3141]

I loved you in buster with Julie Walters and Larry lamb.

[@OldePhart]

A while back I was trying to fix 2 jukeboxes with those players and was told thatthe lasers were no longer available - where did you find those?

[@anthonydenn4345]

Nice job Mark. But it makes me wonder what was wrong with the other one. It was drawing so much power, something short on it maybe. Should of put it on your bench psu and feed it some power. Let the magic smoke point the way : )

[@diazsuryo]

Hi marks. Can you share the arduino sketch for cdpro 2. I have the same device. I want to try cdpro 2 with arduino. thank's.

[@Johnathan_Waters]

Looks like the old Philips CDM-12!~

[@harcovanderpoel2049]

Where do you get those parts from. Mine broke down today 😢

[@paulharris9694]

Hi Mark I have a jvc l-e 600 which has lost all power to it how can I get this to you so you can look at it cheers Paul

[@MendItMark]

Hi Paul, you can find me at www.perton-electronics.co.uk.

[@SubTroppo]

How many CD players could I have saved from E-waste? ps Is it still Telford "New Town"?

[@petenamlook18]

Why no fresh lube on the sled rails while you were in there?

[@MendItMark]

A good question indeed! Well, it didn’t have any in the first place, and the bearing surfaces are a waxy plastic ( acetal or nylon 66?). It did move very freely, and it’s not under any significant load. I also remember a physics teacher telling me that a lubricant has to be an adhesive first. Go figure… Thanks for watching!

[@RebelDean1]

Hi mark, I have the same Sound Leisure cd playing jukebox, and it all works apart from the disc will spin and stop, spin and stop. |ve tried all the usuals, and now coming to you after watching this great video. I wonder if you can help?

[@HOTAIR83]

Co to za naprawa to wymiana tylko uszkodzonej części a nie naprawa.

[@Rockabillyman26]

Hey there where do you order cd lazer parts to?

[@MendItMark]

Various eBay stores do them, you just need to know the correct model number. A bit of Googling helps with that.

[@talktorque9330]

Hey Mark. Just bought a “Playmate 200 Selection” wall mounted Jukebox. Is this something you could help with? Thx

[@aliisk6575]

[@dank1tag]

Hey Mark, just wondering where you purchased the replacement laser for the cd player pro?

[@frankowalker4662]

That software is useful.

[@erikhenriksson455]

iPhone has an infrared filter so you can’t use them to check your remote controls!!!

[@mavrickfaldo8866]

That must be what's wrong with my cd unit from the jukebox 😢😢

[@Lackooo84]

I can see every cd dvd or bd laser with my naked eye. Weird.

[@mogenslundjepsen5158]

Hi Mark. Thanks a lot for the great video on CDM-12 OPU repair. Good job and nice videoes. I have 2 questions. 1. The test stick, where do you get it, or how to create them ? 2. Regarding the Arduino test rig - Do you have an wirring diagram/schematic ? Thanks in advance

[@GREEN-tc7xj]

The laser may kill the phone's CMOS.

[@SassyXR6007]

Do you read comments Mark? I know you don't reply if you do 😂

[@fu1r4]

I noticed you put the CD upside down. Are you aware of that it is the upper side you need to be careful with and not the underside? If you get a scratch in the plastic the data is still there, but if you scratch the upper side (the reflective layer) the data is lost.

[@howardtaylor229]

No You are upside down

[@akella728]

i missed U

[@howardtaylor229]

Your videos are usually packed with very helpful information and techniques but you fell a little flat on this one. There was the tidbit about replacing the laser but in my view the meat of the video was the Arduino board and the script you ran to assist with triggering the unit. THAT is what you should do a video on. THAT was the most interesting part of the video but you walked away from us with the secrets in tow. Please do a video on that board and the scripting software. Thank you - your friend Linus.
