CD Player not Reading Disc Fix - Increase Laser Power (to 11)
Вставка
- Опубліковано 3 жов 2024
- A relatively quick fix to an age-old problem: your CD player sits and spins the disc making weird electronicky noises for ages, until either working (until you skip), or until your nerves give up.
Make sure to only increase the power to lowest satisfactory amount
Everything about this video was perfect: your attention to focus, lighting, zoom, angles -- perfect! Also you explain the issue with fluency and keep your verbiage lean and to the point. Thank you
i do not use wetness on my laser lense only the Q Tip wipe gently once a week
Tried this on 30 year old Technics which just stopped reading cd. Amazingly it worked. Christmas magic. Thank you for a very clear video
Did the same thing with a Technics CD Player, Model SP-PG480a some years ago and worked really well. Now i have another (same model) and cant remember how i did it. Do you have a guide of the values for the adjustment?? Thanks in advance!!
@@ecanavessi please have a look here buddy... www.hifiengine.com/manual_library/technics/sl-pg480a.shtml
You must be very careful to check before turning the pot that it hasn't got a spot of weak glue (like a nail polish) sometimes red in colour which is used to hold the the pot you turn in place. If you don't remove that glue/nail polish whatever it is the the whole pot will turn ripping itself off the circuit board damaging it completely. A dab of isopropyl alcohol on the pot for 10 seconds before you turn it will suffice.
I've been looking for a lot of repair movie clip so far. Most of the videos were about replacing or cleaning pickups. I couldn't find any explanation for calibrating the laser power. After watching this, I fixed the CDP that was difficult to fix very easily. Thank you very much.
Thank you. I have a 20 yr old Bose acoustic wave that was acting the very same way your stereo was acting, spinning the disc, but no music, did the adjustment and whola!!! Mu-zac was spilling forth!! Thank you...thank you...THANK YOU!!
Absolutely brilliant. Thanks so much. This has corrected my pioneer cd changer.... fantastic. Thanks again.
glad everything worked out ❤️
As a laser diode ages it loses it's conductivity like a dimming bulb. To compensate the current going to it can be increased by this small pot to allow the laser
to become brighter and read the disk correctly! Just don't turn it all the way up or the current will shorten it's lifespan very quickly. GOOD FIX!
thanks for the explanation!
would you expect this to work multiple times ?
Wouldn’t increasing the current cause the unit to overheat ?
yes, which is why you have to be very careful with how much you increase it
it'll die out due to being pushed too hard before overheating though - it's usually part of a big metal casting
@@michaelfeeney8437 Yes but you could monitor it but that may call for some expert analysis with a meter.
Fixed a Panasonic RX-DS750 boom box that was built in 1996. Laser adjustment can be accessed without taking unit apart. Insert CD, select something around track 6-10. Stop it and remove CD. Head will be aligned where you can get a small screwdriver in the gap on the left side of head. Mine just took about a 10 degree counter-clockwise adjustment of the screw. Thanks for the video!
Thanks very much for this info, I have just fixed a Marantz CD-63 mk2 KI with this technique. Currently 17 mins into a CD which it could not previously even see! This is a must share video.
I'm glad it helped! It sure helped me fix at the bare minimum 50 car radio cd modules
Hey Dan, Please let me know where is the potentiometer located in the Marantz?
@@zoranspirov1305 Hello, I'm afraid that I cannot remember exactly where the adjuster is but I do recall that I had to remove and refit the whole carriage every time I adjusted it. Not too difficult to spot once the carriage is out and the mechanism is upside down. I did not remove any other parts to access it. Good luck, it's a great CD player. Ours is still working perfectly...
Thanks
@@dangodfrey480 Thanks Dan, I'll surely try and fix it.
Recently purchased a 90s technics CD player for my setup. Burned a cd today and ran into this problem. Saw your video, popped open the hood and followed your directions and BOOM! It worked! This is what UA-cam is for! Thanks so much! Managed to fix it!
glad you got the job done ✌️, just be aware to always boost it by as little as possible
Great, I just followed as u said . Tank u so much .My Bose wave radio CD started working more than I expected. It is a vey good lesson to every one who face similar problem without spending anything. God bless.
This method worked flawlessly on an old Technics SL-P111 cd player that i purchased as part of a vintage Hi Fi setup. It was the only piece not working. Super easy fix. This is what UA-cam is made for. Thanks so much.
glad I could help ❤️
Thank you so much. I didn’t want to put any crappie aftermarket stereo in my 1999 Plymouth Neon Expresso. Now thanks to you my factory Chrysler stereo is working again!
lmaooo
@@tylerevans2261 Not gonna lie. I replaced it with an aftermarket a week later 😂
Thank you for the tip! I did this on a JVC PC-X300 ghetto blaster I bought new in 1989. The CD stopped reading 10 years ago but the unit is otherwise in mint condition. Was about to give up on it until I started researching and found this video. Only thing different is I had to turn the trim pot clockwise for it to read the CD. Thanks again for sharing your knowledge, this has brought new life to my old classic stereo.
70 year old woman here. Our 30 year old 3 disk CD player was not reading in any of the positions. I bought a cleaner disk that would not even read. I was thinking of buying a new one. I decided a drastic fix wouldn't hurt anything. I doused an unwanted CD in alcohol and put it in and tried to play it. It didn't work. I then poured about a teaspoon of alcohol on the middle of where CD #2 sits. I closed it and pressed the play button. It played funny for a few seconds and then it worked just fine. I played it about 30 minutes and it was still working and the alcohol had evaporated. I'm not suggesting this method, but I didn't need to unscrew anything. Now I don't need to buy a new CD player in 2020 when they are on their way out anyway.
yea, a microfiber cloth damped in alcohol is what fixes 70% of my lasers too
the other 30% do require this nuclear method of boosting the laser power
I'm sure you'd be more than capable of doing that as well with a bit of patience :D
@@Darieee I do fix things around the house. Our toaster over door wouldn't stay closed till I fixed it. Just in the last couple of weeks I spent hours updating a Windows 7 and an 8 to 10s (waited too long because I didn't like W10). But I really was ready to get a new CD player and had lost patience. I take of lot of risks when I fix things because I don't know what I'm doing, but it usually turns out all right. I should mostly make sure I unplug electrical things before working on them. In my younger days I would have disassembled the CD player, and tried what you did, though.
I can't thank you enough for this video. I just pulled an old Sony Discman D-1000 (which I loved but had given up on) out of the closet and fixed it based on the info from this video. I can't believe it. Sweet!
enjoy ❤️
15 deg counterclockwise just saved the day on a Bose Wave Music System. Re-capped, but was still hesitating with track changes. Th@nk You !!!
glad I could help ❤️
My Denon DCD-510AE wouldn't read some of my discs. I was just about to shell out almost £300 for a new player and I thought "Give this a go. Nothing to lose. It's not working anyway." I can't believe the slightest turn of a screwdriver and voila, problem solved. It might deteriorate again, but at least I still have it for now. A small miracle. Thank you sooooo much!
Thank you. This helped with my Denon CDC-680. I had to take a guess fir the right potentiometer because there are 3 next to each other. The left one did the trick.
Do you mean DCD-680?
I ask because my Denon DCM-440 does not read intermittently.
Lou Fazio , Yes I have a DCD-680. I cleaned the lens with a Q- tip and fiddeled wit a pot. Now the player reads more discs but not every new one. I was thinking of tweaking it one more time. Maybe the dust cleaning did it??
@@amajorseven It is recommended to use a microfiber towel wrapped around a screwdriver tip. Maybe at least a blast of air from a duster can. I'd bet film/dust is not the issue.
For mine (carousel type), I'm thinking it may be the disk turning into full position as a read begins. A belt replacement did restore its tray action.
OHMYGOD My AIWA cd player wouldn't work and you mentioned window/screen wash on the lens, I did this and voila! So a thankyou from me for this video existing.
yea ... there really doesn't need to be much on there for the entire operation to grind to a halt
glad I could help ! have fun with it !!
Unbelievable! Kenwood DP-4030 (from 1992) back to life 😀! Many Thanks for you video and the explanations!
Thank you! I"m going to go try this solution on my inoperable CD player (my two young boys just discovered my CD collection and they're mesmerized....who would have thought!)
I can't believe it actually worked! Thank you! Mine was a pioneer brand and I had to turn clockwise.
Darieee, you are an awesome electronist, I'll give you that. But regarding the 650 MB /74 min CD info... I must tell you I have just bought around 85 pieces of those (from multiple sources), just to realize that a modern 80 min Maxell CD Audio XL II 80 (high reflectance) will do the job. :))
Meaning the info you provided was "asa am crezut eu"-type and actually it was about the CD-R reflectance, which was higher on older CD. But so it is on modern audio ones.
Anyway, thanks a lot for this laser power tip! It's very good to know info although my 1998 Alpine Audio 10 worked without it.
P.S. For burning I use an external Plextor BD-R which is capable of 4X, but 10x works just fine.
Genius!!! Thanks a lot for the tip, worked perfectly! ❤
You got me and my thumbs up at, “...it says fuck it...”
I WILL be checking out more of your vids. To the point, honest AF and helpful. What more could be asked of a FTS video.
Thank you!
Thank you for the explanation, although a bit technical for a novice such as myself but this tutorial is a great help.
CD Player: mmmmmh *kLick* *scrach* zzzzzzz *BeEp* rtrtrtrtttrtrtrtrtrrtrtrtrtrtrtrtrtrtrtrtrtrrtrtrtrtrt
Also The CD Player: WHY TF CANT I LOCK ON THIS GODDAMN DISC?!?!?!?!?!?!?!
Just tried works perfect, thank you.
my pleasure, have fun 🤘
My wee Roadstar music centre had a dodgy CD player, it took 4 attempts to read a CD. Now the wee bugger reads like a university student!
nice 🤘
That's the problem I'm having with my Pioneer CDJ 800. One of them is not reading any CDs at all. I called a place to see how much they will charge me to fix it, and the guy said that it's $160. 00 dollars just to look at it. Right now I can't afford to replace them due to the job situation with this COVID - 19 PANDEMIC. I wish I could fix it myself or knew someone that would fix it for me at a reasonable price.
Worked like a dream on a Marantz CR-612. Thanks!
nice 🔥
Very interesting video! Thanks a lot.
Awsome men!! I haven't tried yet on my stereo, but this might me what I need to fix it
Sitting here with open mouth, wondering how on earth you got the idea that the problem is that the laser is weak and that this particular trimmer would increase the power and solve the problem. Wow...
yeah, shouldn't be that amazed ... I mod mercedes radios now, and at some point had quite a few with defective cd units
I also started to (and still do) have around 3 4 5 busted cd drives ... with some broken plastic parts or dead motor drivers ...
so I did take a laser completely to bits once ... to see if maybe there's something I could clean
and there, when I held just the laser assembly in my hand, I saw this trimmer, clearly going to the laser ... turned it not knowing what to expect and hey -- it worked !
(afterwards I did see there's another dude on youtube also suggesting this, but mainly just people telling you to clean the lens)
wow, I just try to fix my OEM cd player from China. Just found your video, and it works! Thank you!
Good fix Works the same on a laptop cd drive. Just did this with a q tip and circuit cleaning spray with alcohol and it fixed the drive
awesome 🤘🤘
its always the case isnt it?....like when you have a problem with your car, you hear a noise, when you take it to the mechanic....no noise...arrghh!...dont ya hate that?!
My 1996 Toyota Camry LE’s OEM CD deck uses the same laser assembly as this. Interestingly, there is a sticker on the deck’s outer casing that reads “US 4,527,265 under license of Staar S. A. - Brussels - Belgium”. Perhaps Fujitsu Ten (who provided the stereos for Toyota) and Mercedes used the same manufacturer for their audio systems.
Definitely going to try this on my Denon DN-S5000 CD Turntable, as it just does Not want to read CDs and I've tried cleaning the CD and then cleaning the player itself and I had always wondered why it "Looked" like it was struggling via the screen showing all pertinent information was bright, but then a little less bright and then even less bright...... and then trying again..... really Bright, then less and less. Finally, saying "Disk Error"...... I will let you know how it goes and I will only turn it in small amounts as to Not burn something out or beyond repairable. Nice 1. Appreciate the video, as there are not to many on this type of problem for CD Turntables. Beauty. ty. L8er vader.
@@Darieee ...... Problem!!! I can't seem to find "ANY" bolt, nut, screw to turn and dial up the laser power output. No reference point, as this CD drive is "VERY" different from other drives...... I think,,, I believe. lol. I am trying to look it up now. Either way, I Will let you know the outcome... and again, thank you for your video and input. Always nice to have more Input and Info when working on a project where my knowledge is sub-par. L8.
This can be caused by the cd platter dropping on the motor due to age
Thank youuuu!!! Fixed CD player and DVD player
learned something new today.. awesome. I'm getting "Initializing" and "CD error" on my Ford cd-6 car stereo.. looking for a resolve. thanks your video
Yeah, first clean then boost in very small steps
You should be on your way :D
Thanks for your help, found the potentiometer but rotating it didn't help my Bose CD player, looks like its busted and replacement 3rd party parts are unavailable.
Sorry to hear man
ebay, all kinds of laser CD DVD SACD drives available
maybe a bit contactcleaner had probely already don the job to, but maybe the led degrease small in power strength by time, but thanks, dariee be good to know were too look for 👍
the cd player says 'god damned son of a b£$£%£ you s%£$£ cd, get the F3$£ out of me!" (kinda like a good saturday night eh?).
i'm being satirical btw. the guy says the cd player says fk it. lol
This is well explained but I’m so lazy idc I’ll find another way LMAOO
how do you know whether to turn the potentiometer clockwise or counterclockwise?
Awesome, Thank You so Much !!! Works Great now!!!!
THANK YOU SIR .
Stereo not working after removing CD player ...is there any way to bypass
I have a alpine CDA-9847 that won't play the CD saying error so I took off the top cover and noticed a spring fell out and not sure where it goes thinking this might have something to do with it also.Do you know anything about this?
Going counter clockwise seems to weaken the power as it barely attempts to read the cd in my case. It seems i cant go anymore clockwise... any other suggestions???
My player doesn't spin when a disc is inserted.
Interesting. I have a 10 stacker Eurovox on my GM Holden that sometimes will not play a commercial cd. Made in 2000. Maybe this is why.
might very well be .. either dust or needs 650MB discs
On two of our cars (older, 2001 and 2003), the disc is taken inside, then makes 3-4 clicks and then comes out. Occasionally it starts playing, like catching smth inside of the radio CD player, but in most cases, the disc just slips and comes out. What that can be and how to repair this problem? Thank you for the great film.
the mechanism's plastic bits sometimes break .. some springs sometimes ping off
you'll need to open the radio and get to the cd-player module inside
also - it has a rubber roller which catches dust and loses its grip - some window cleaner on a rag takes care of that with spectacular results
@@Darieee Thank you for the replay. I tried to clean today w/ a disc made fm/thin cardboard 2001 Saturn SL2: moist it a bit w/91% Isopropyl Alcohol and inserted in CD player opening, then removed it slightly wiggling around. I don't remember if I pressed the Eject button, probably not. The cardboard was removed, but the slot got stuck in the way that I can't install CD anymore. More of that I tried to push those parts inside w/CD and all the doors started to lock in and out like crazy. Eventually I closed all the doors, but CD player is broken completely. All that has very good outcome though, since that car started to have a problem recently w/doors, they would got open, all of them from time to time, and we couldn't figure out what causes it. Now I know, that the malfunctioning radio unit causes it, bcs the disk was sitting inside. I'm planning to order new radios for both cars. Thank you again.
let me know if I can interest you in some with Bluetooth ✌️

After the adjustment it started playing, if you stop the cd and insert another one it does not play anymore.
Thank you soooooooo much! Helped me fix my xbox series x!
wow, nice !
Only works with 80s cd players
Any thoughts on Panasonic home console recordable laser pickup assembly (e.g. RAF 3331A-C from a DMR-EH75V)? These things are not having much lifespan for me (hardly even used).
I have one of those ILive ipod/cd components that i got in 2015 still fairly new and it doesn't play certain cds. Just spins .what can i do
Salut, am un Becker 24v,mp3...este montat pe un camion original de fabrica, de ceva timp nu vrea sa citeasca CD urile, indiferent daca sunt format mp3 sau audio, am scris Cd urile maxim pana in 650Mb,la viteza de 8x,am curatat lentila si tot fara rezultat. Orice Cd bag in el, da sa citesaca apoi in cateva secunde il da afara cu eroarea pe display cd error.Ar fi o solutie sa scap de problema? Multumesc
I wonder if this technique will work on a ps4
My Venturer dvd/Cd player doesnt have any picture!only sound on both discs,any ideas for a fix to try,thanks.
Hmm, not really, if it can read the discs just fine then it's surely not the laser module at fault
I screwed it to fast and broke can you pls help me out
Hello, two questions, 1: how much lifespan after this procedure? 2 some laser is counterwise or the opposite?
If it is the opposite it won't do any damage, just turn it the other way
Hi I have a FORD BA 2003 UTE WITH A 6 STACKER CD THAT WON'T READ CD'S & EVENTUALLY EJECTS THEM EVEN AFTER USING A CLEANING DISC MULTIPLE TIMES. SO IS THIS THE NEXT STEP FOR ME I WAS HOPING NOT TO HAVE TO REMOVE THE PLAYER FROM THE CAR I AM GUESSING THIS CAN ONLY BE DONE BY REMOVING THE MODULE, IF THIS IS REQUIRED IS IT DIFFICULT TO DO ON THIS MODEL? THANKS APPRECIATE YOUR HELP
Master!... Thanks
Sir my ford mp3 palyer getting E01 error after cleaning the lens plz help!
I didn't think mp3 players even had lenses
wow! works!
Could this be a similar case for CDJs?
Thanks for sharing👍🏾
hi, sir!! video of fixing wall mounted cd player that is not working and has unnecessary noise please thank you
Thanks bro👍👍👍👍
Thanks for the info !!
Good post. Have done this as short term fix, might get a few months out of them if you're lucky, never had any long term success in years by doing this because the diodes are breaking down, it speeds up their demise by increasing the current. CD lasers are all pre-set when new and they should never be adjusted from new if they do not work. I have had defective ones which iv'e had to send back. Buying and fitting a new one from a decent supplier is much better depending on your on budget, they vary from £10 to £500 or more.
hmmm .. well, to be honest I never had the chance to test them out long term ..
have you had them die out 'again' ? what kind of run-time did you get ?
@@Darieee Got a few months, but not years. In the end they fail to read the TOC because they can't focus, you can hear the laser knocking the disk sometimes. I think other people might be lucky and get more time out of them.
Got it! Very interesting insight - thanks for sharing 🤘
Perfect, but is this a temporary fix? Does this shortens the lens lifespan?
the laser will be under more stress, which is why you have to increase it as little as possible
given I don't listen to CDs at all, I can't say I've ever stress tested this approach
I have a 1998 Mercedes sl500 and it reads NO CD.
Thanks for sharing!
Why not putting a Mp3 CD-reader (lens) in your car stereo. ;)
Sir can I do this in dvd player
Many thanks fixed myn last night but it still doesn't like CD/R 700mb discs. Guy on another vid says 650mb will be OK.
Hey, Thanks for the video. I've got 2005 Nissan Pathfinder with 6 CD Compact Disc Changer. I've tried almost every single CD which I had (including original or manually burned) and it only plays 1 particular CD which is Classical Music Collection. I have also cleaned the laser reader and nothing changed. They told me to replace the laser, but its really hard to find it. So is there any solution that can be found or my car is just a maniac of Mozart and refuses to play other music :)
Mmmmm, so original releases also don't play?
It might be an old laser module capable of only playing 650MB discs
Or did this laser power boost fix it ??
@@Darieee It says MP3/CD PLAYER, but unfortunately it doesn't read anything except the above mentioned. :(
Would this work for a portable Sony Discman? It stopped reading discs but if I put hot air inside the disc door (5 seconds with a hairdryer) it works every time. Diode flaking out? Hate to throw this super-rare D-828K away.
could definitely give it a try 🤘
My dvd- 106 is not reading cd plis help
Do al lens come with this variable voltaje control? I could not find it in my Panasonic radio casette
maybe it's somewhere else ..??
Counterclockwise? Are all potentiometer adjusted, for this purpose, in that direction?
who knows .. this is why it's advisable to adjust it only microscopically and check results ✌️
Thank you!
Trained novice. Lol. Good info, but great quote! 😂
Hello how the console pops out ?
does this work on all cd readers for example in my sony mxd-d3. It realy strugles to read CDR and CDRW
it might be that some players struggle with 700MB discs
if you're sure that's not it, you could try boosting it
Hello brother,pls I have tried my possible best to clean my s320 benz lenz but it kept playing a I second and stoping.and I dont see how to adjust the lenz.
mmm ... it could simply be another problem
or.. did you try boosting the lazer power ?
@@Darieee thanks for the respond,the problem is that Benz s320 radio in very complicated to reach where the boosting adjustments.if I could adjust it I believed it will work but only if I see a pro to open it and do that on the video,then I will be able to penetrate alike.
Hi,
Does trick apply also to MiniDisc players too ? 🤔
I have a Sharp MiniDisc MD-T20 unit which gives me a "NO DISC" error everytime I put in a MiniDisc. 😞😭
I was able to fix the TOC ERRORa fairly easily but now this is happening.
Thanks ! 🙄🖒
Best Regards,
what's a TOC error - and how did you fix it 🔥, sounds interesting
as long as there is some adjustment somewhere on the assembly / main board, it should be doable
maybe if they got their tolerances tight enough you'll have to swap an SMD resistor
just remember to only SUUPER slightly tweak the value
do let us know if you had any luck
@@Darieee Edit: I was able to fix the "NO DISC" error. I guess I had to turn the trimmer potenciometer a lot. 😃
I'll make a video on the "TOC ERRORa" issue in the future.
Wow. that is great, I need someone near my place to fix my radio in my honda.
E. M. Torres where you at. I’ve been repairing radios for over a year now.
i got a sumas 310t cd/dvd player and it want read any cd or dvd and the usb port will not work, anyway to fix thiese issues?
That's a very weird question to put under an entire video dedicated to answering exactly said question
@@Darieee so cleaning the eye will allow the usb port to work?
Yeah good point - that part of your problem is most likely cause by other shit -- maybe try cleaning the contacts inside the port? Check if the plastic piece is not broken in any way and that the pins are not bent out of alignment ?
@@Darieee ty ill try
Notification squad!
On call as always xD
I tried ur method it was working and now it is giving trouble again “disk not playable.” Pl suggest any solution
uuu yeah ... your laser might've died
try somehow swapping it out for another one 😳
Cooooooool, thanks.
happy to help! what did we just fix?
@@Darieee Nothing yet but I will be taking apart and cleaning a Samsung DVD player with very few hours on it but was sitting uncovered in a dusty area.
How did you discover that you have to turn the pot counter-clockwise to increase the power instead of the other way? I'm sure I've seen other videos where they turn it clockwise...but I could be wrong.
ah ye ... just nudge it ever so slightly one way
if that works it MUST mean you've increased the power 🔥
@@Darieee Just don't wanna risk damaging the thing by mistake, but thanks anway.
yeah - if a slight nudge one way doesn't do it
go back, slight nudge the other way around ... then increase the amplitude and try both ways again
if it doesn't work now ... and it doesn't work after a try like this ... it's hard to say who did it 🤘
@@Darieee I appreciate yoiur answer and I shall try that - thank you.
F&*%^ing amazing. Thank you so much.
Lol I've gotten do frustrated with mine that i just turned the pot all the way up. Yet, it won't read any discs, which is weird considering the fact I can see the laser turning on. Whatever...
Could be some other fault in that case ... did you first turn it just a tiny bit though xD ? Because going all in from the start might damage some shit in there
Same in my case. Adjusted but not detecting cd anymore. What can i check further? Can u help me.
