Does this fix work for indash car CD player ? Displays no disc when there clearly is..
@@charliejeans2413 it should if there's a pot on the pickup assembly
my dvd diode cant back into center disk, need to push manually, do this fix mine?
Thank you sir, I just bought an old 1990's old stereo all in one CD, radio, cassette player RCA for $15.00 only the radio would work, I followed your instructions and now the CD works, I had to crank up the switch turn it 2 clicks and now it works, RCA is not great but it worked thank you, now please my eject button wont open can you help, I have 7 screws left over but it works cheers man, I had the sides off, the back off, the front off all upside down with a flash light it was tricky on my knee sir. The dust must of been 20 years worth.
Electronicle I did it I did it I did it I did it your and angel bro my family is now enjoying thank you bro 🔥🔥
Your video allowed me to bring my Sony CDP-S37 from 1992 back to life!
It's people like you that make the internet great! Thanks a lot!
how long it can last for doing above? Thx!
Totally agree, I love fixing stuff and this trick worked a treat on my lovely old JVC UX-T100 made in Japan, not Taiwan.
am suprised they act use screws cos thry normalh make it sk u vant repsir it but if this is sooo good iff every1 starts doing it they will changd the way itd build j go through dvdx xboxes ps2 ps3s like smartys in the last 6 half years ive hsd 3xbox 360s ps4 p3 snd ps2 no ive had 2 ps3s and honestly about 15 to 18 dvd players k have 3 rite now what am cleaning the lenss on whicb help z bit but then stop so sm gonns try this rite now bloody hell it will savd md a ton of cssh iff it duz i will senx you a donation cos my mamx dvd player duz the samd shssd hsd sbout 12 dvd plsyers in last 6 years .and why both 6 years is cos thats when i movsd bk in with my mamplus if never usto happen u usto by a disc cleaner that was it..why are we getting this lproblem its weird
Im not really sure about this , to tricky for me but my son could do it , so thanks for the info
@@jamescheung6004it was more tricky than the video described. I think this fix could be a year, But the knowledge will last forever. I subscribed, because it is a tool to oppose planned obsolescence.
Thank you! I was able to get a portable dvd player going again for a young boy who has no tv or computer to watch anything because he and his family are refugees; the look on his face when Toy Story started playing-priceless!
I just repaired my seventeen year old Denon UD-M31 by following your instructions, it’d read some CD’s intermittently, I turned the all important screw anticlockwise as it wouldn’t go clockwise, turned it about just under half a turn or a gnats tit, anyway it’s even reading slightly scratched CD’s like my original Shaved Fish by John Lennon. I cannot thank you enough especially for making Covid-19 lockdown more bearable 👍
Half a turn means nothing!
Dude!!! Just 10 minutes ago I made my Denon work again. I’m so happy for this, and all thanks to you and your video. I just used the Q tip and this did the job. Dude you deserve a 6 pack of Heineken. Thank you so much.
That worked! I bought annold but very high end player. Tested it, worked. Came home, didn’t work anymore. I guess the car ride was the final straw. Bumped up the laser voltage just a tiny bit: works perfectly now! Thanks for this tip!
Thank you. Watching this video gave me the confidence to remove my CD player's chasis and knowledge to clean the lens, which was basically all I needed to do to get my player working.
I'm doing the same as mine won't read. It's got low hours on it but been sitting for about 6 months, so I'm thinking dirty lens.
@Rex Erection I recently tried one on a unit that wouldn't read CD's and it didn't help. So now on to tearing it down and cleaning it his way.
@Electronicle : Thank you so much for those videos. I just fixed my Harman/Kardon BDS.
@Tinkmarshino : I ordered a set of Pentalobe and electronics screwdrivers instead of "trying" with the stuff I have at home.
It worked #1. Now I have a set of tools to fix my electronics, and I can listen to my CDs again… Cost: 25$. Benefits: I learned.
Awesome!
I gave this a try and it worked for me. The ohm ranges were too low for me to get a good reading with my Fluke as a baseline, so I just tweaked them both up about the same amount as in your video and my DVD player came back to life. Thank you for sharing this.
Just fixed my LG 4K home cinema player.not worked for 2 years,thanks a million,saved me time and money👍👍👍👍👍👍👍
Worked on my Yamaha CD player, did clockwise first didn’t work, back to original position and half a turn anti clockwise and worked, thanks mate 👍
This method perfectly works with my old 1998 Sony Discman D-171. No disc error fixed! Thanks a lot
Just to thank you, cause i've just fixed my Kenwood that wasn't working for about 10 years. I did try a lot, adjusting to the left and to the right on 3 three different screws next to each other... and when I was about to quit, it started to work. First the sound was still a bit weird but with another small adjustment I made it work perfectly. Can't thank you enough!
This inspired me to open my old JVC console CD player that would seem to pick and choose which CDs it would play, and after cleaning the laser and slightly tweaking a screw I thought might be the one you were referring to, it now works. Not sure which thing actually did the trick, but thanks either way.
Before going to this extent, I’d recommend simply removing, cleaning and resetting to connection cable. 9 times out of 10 that’s the real issue and adjusting the settings may not be necessary. It’s very possible that was the issue here as well and the adjustments weren’t necessary.
Can confirm this. Successfully fixed mine just resetting the ribbon cable.
I do agree with the contacts at the ribbon. I had that happen with a laptop
Obviously most people would have tried cleaning the laser and ribbon contacts already. THATS WHY WE ARE HERE. Judging by all the positive comments on here you are incorrect.
Ive done all this with multiple dvd paystations ex boxes ans my mams had the same thing weve prob spent ocer. A 1000 pound in about 8 years am sick and i do not undeestqnd what is going on.i was thinking 10 bit ive had like 2 ps3s 3 xboxes about 6 dvd players and my mams had about 8 and i do alk this then i take them 2 bits works for bit then week later bk to the start ..what is this resetting thing plz i dont understand
@@eyefishinggunkchannel1011there might be other videos that explain it a bit better , I can't help as I'm not sure either , I'd need to pause it as it goes along
I have used this repair method myself, but it gives a good effect, usually for a short time. This involves contamination of the optics, which are not easily accessible, only the lens you cleaned can be accessed, and the increased laser power supply current is also a factor that shortens its life. A proper repair involves replacing at least the mechanism with a set of optics (they are not always easily available on the market - it depends on the model).
Thank you, my friend. Your helpful information restored my JVC Compact Component FS-M# System. How can I say thanks for all the things you have done! So glad to learn this. God bless!
I cleaned the lens on my dvd player after watching this. It works now. Thank you!
Nine times out of ten, cleaning the lens is enough!
I have 2 identical Magnavox DVD players with the same problem. They both are the 1 out of 10 that this won't fix.
How you clean it?
Thank you so much!!! Cleaned laser with IPA and a cotton bud (Q Tip) on my Pioneer DVD player (model DV-686A-S) as per your video here - perfect, works again! Thanks so much! Didn't see any pots to adjust, but luckily the clean did the trick! Have to say, the laser didn't look dirty prior to cleaning - proof is in the pudding I guess!
Thank you so much sir. yesterday I visit the service center and it took 150$ to fix my cd player. but I fixed by your way. I deeply appreciate your help.
Wow, thanks. My Aristona old CD-player just has one potmeter near the laser that I turned slightly clockwise and it works! It plays all the CD's again without a problem!
I tried this cuz I found one of his other videos first that showed the same thing. It works! I can't believe it. But I just did it to a DVD player that has been sitting around for years. I think from before I was born and it works now too!
Good video showing a possible problem scenario.
Trimmer pots become a bit oxidised and high resistance over time. Therefore the setting is no-longer in spec. Moving them slightly might clean their contacts a little which in this case helped but you really have no idea if the calibration is correct or not. As pointed out, it may go over spec and burn out the laser. If the high resistance is elsewhere, like the tabs that hold the contact wiper in place. Doing this will not fix that. My suggestion is to get some contact clearer lube such as Deoxit spray. Do not spray this directly on the trimmer But spray a little into a small container. Then dab the smallest amount possible onto the trimmer contact points and dab these areas with the corner of a tissue to soak up excess conditioner. Wait for it the dry before powering up and testing again. This should soak through the oxides and regain continuity through the trimmer without moving it at all. If this is the least invasive approach and you can always try moving it if it doesn't work. The brand I suggest is expensive but is pretty safe on most components (some aren't). It is a product that can be used to clean and lube scratchy potentiometers such as volume controls as well as faders and faulty switches.
Yes. That's what I have thought too. They go high by themselves at the point the contact touches the carbon track. By moving it slightly yes you are adjusting the factory setting, but prob more freeing the wiper on the trimmer and making proper contact again.
Yep. My 11 year old anthem blu ray stopped reading some blu rays---everything else played fine---i turned the pot a teeny bit clockwise and then back to where it started. Now it works like new. reads discs quicker too. so, i think just moving the pot broke some oxidation .
Very informative. I was able to set right my 20 years old Sony MHC-G50ii mini hi fi component system by adjusting the Potentiometer on CD Drive. Thanks a lot.
From India.
Glad it helped
Thank you --It worked and saved me from having to take it in to repair for a Minimum of $20.00 to look at it and then the cost of repair.
In older disc players that have ceased to play or even load a disc, the fault my not be a weak laser, but rather oxidized connections and contacts: as someone else here suggested, remove the ribbon cable and use a little contact cleaner on it, then re-insert it and pull it out a few times to clean off any oxidation. VERY gingerly, as these thin flat cables are uber delicate. Same goes for the diode current pots: mark the original position of the wiper, spray a little contact cleaner (a very little bit goes a long way) on the carbon trace, and turn the wiper back and forth thru its full range a number of times, setting it back to the mark. If this does not fully restore function, then try turning up the laser current a little, maybe 5 minutes (clockwise) as viewed on a clock face, that is, 1/12 of a circle. These procedures have worked for me on several players as old as 35 years. The unit Mr. Electronicle worked on in the video has the diode current pots in a relatively convenient location for adjustment. Most of the players I have worked on have the pots on the underside of the laser board, which is a REAL pain in the arse , necessitating removal of the laser unit.
Does this work for portable ones? I have a Phillips DBB portable one showing no disc.
One thousand thanks, my friend ! It's something I can't do by myself, but I can show a technician HOW this can be done. I live in Rio de Janeiro, Brazil, and good technical assistance for sophisticated devices is something too hard to find here, mostly lately. Best regards, once again many thanks !
Thanks for the insight. I got the no disc issue resolved by 1)gently wiping the laser with denatured alcohol. Then 2) Bringing out the cable and cleaning it with a soft eraser. The type kids use for their pencil works. Erasers do great cleaning jobs on signal cables. Cleaned and reset the cable. That just did it.
It's not always the laser diode going soft ... it's often the track on the tiny potentiometer that gets dirty and grimy so making the contact with the wiper unreliable .. I personally would mark the position with a very fine point... and then spray they track with electronic cleaning solvent and move the wiper quickly from one end of the circular track to the other.... this beds the wiper in and reduces contact resistance...
Great Video!! Just threw away 3 Lite-On drives that each said Power Calibration Error! This tip might have saved them. Replaced w/Plextor PlexWriter PX-891SAF drives from Amazon. Will remember this for future use if needed.
I just fixed a nad cd player I found in a Goodwill for 7 dollars by watching your video and adjusting the voltage screw. Thank you very much.
hell yeah man..good job!
My first CD player was an NAD. Awesome product; it was rated best in its price range. I've had 3 CD players since the NAD; all pale in comparison. I am green with envy.
Thanks Sir, nice video full information and clear step by step........Didi, Jakarta Indonesia
Thank you so much! 🙏🏻🙏🏻
You are the man!
Worked, and I will always be grateful for the knowledge, the added life, and the anxiety relief, especially in these trying times.
God bless you
one more thing that will make fixing things easier.. actually it is a saying that's been around for awhile.. it is : "the right tool for the right job" It will make your job so much easier.. so before you start your project make sure you have the right tools.. Good job on this fix.. I learned something new..
Tip 2: If you don't even have a multimeter, you probably aren't qualified to fix a DVD player...since what you really need is an oscilloscope and a multimeter and a service manual. That and a basic knowledge of DC circuitry and components.
Peter Lamont waah,waa-was....dude this is UA-cam,not some electronics classes,the man is trying to help out and show the average person how to fix DVD player.

At 2:50 in “trimmer pots for the laser diode.” Nice! After watching 3 other videos this fixed my Sony CDP-211 - thanks!!
Glad it helped.
Many thanks! My 30y old Sony CD is back to life again! Amazing.
Thank God for u I did this just now and my dvd player that didn't work for months is now working perfectly thank u
Sometimes simply removing and putting back the ribbon cable fixes the issue. Oxidation may take place over a period of time. Also, the surface of the pots could get some oxide over time, and thus simply cracking their position can fix issues. Most likely the player will work for a number of years to come simply with what this guy did to fix it.
Going back some years ago (late 1980's through to the mid 1990's) I used to service CD players at a contract job for warranty service when these players were expensive. I was servicing units from consumer level to professional level types. I was doing the tracking adjustments using test CD disks, a scope, and referencing to the service manual. I was servicing Sony, Panasonic, and some other types. I was also servicing VCRs and TV set. We were changing motors, belts, the laser unit assy., circuit boards, and etc. I used a laser meter to verify the laser strength. The factory level service manual normally has the emission specs for the laser for testing it.
Especially with the early generation players the lasers were failing. The newer replacements were usually improved and would last a lot longer. Servicing these units out of warranty was fairly expensive. With consumer type units it did not pay to service them. Better to buy a new one.
When servicing any CD player, never look directly in to the laser if you remove the shield! The beam is invisible to the eyes, and looking in to the laser can and most likely will lead to permanent eye damage. With many models of players the laser is turned on with the power applied, and it stays on. If the CD/DVD player is a writer, while in the play mode the laser works at a low power mode. In the burning (write) mode it is at a fair amount of power. I cannot remember off hand the power levels, but even in the play mode the laser is dangerous for eye sight. The reflected beam can also be dangerous!
If you have a laser tester you can see if the laser is alive during standby mode if you have the shield removed, and put the sensor over the laser lens.
Thank you for that very important warning, much appreciated.
Just Like you said, I'm very particular when the unit is open. Service manual even says to maintain an angle of 30° at a distance of 30" from laser, if one wants to really have a look at the spinning disk
Cleaned the lens in mind and its right as rain again for now. Thanks.
Thanks for taking the time and explained with calm all the process. Some people has no patience at all. But you do care to really teach people the Right Way. Thanks
ahahaha wow , i 4got about that .
i have a panasonic that was a floor display, after while the product changed and so i purchased it.
it has a little tantrum , it likes to keep the disc . also it likes to auto close when it opens up.
forgot that i could do that, been tooooo busy with life.
thank you for your time.
awesome video !
Your video helped me fix two units. It worked perfectly.
Good on you mate! Another thing is if the DVD wont open you will have to change the little rubber band on the front that is slipping.
any advice on buying the drvive band? I have a Philips w SONY disc drive. the belt broke. the band is about 3 - 3.25 inches
@@the1zedog They sell square belts. You need square belts specifically when applying them to small pulleys because they stay in the channels. As for what size? get an assortment. ebay is a good source as well. Get an assortment of sizes and test them until you find the right size. I last ordered some from savevinyl but they since changed names or vanished. Due to the return of vinyl/mag tapes as a media, square belts are back in abundance and websites formerly specializing have found themselves apparently with a sea of competition in retail environments. Which is good for you.
thanks. I took the drive out and there is at least one connection that I don't know where it goes. It's white plastic with a squared off blue tip. It must go in a slot nearby but I don't know what I'm doing.@@peterlamont647
always pays to take a pic if you don't know what you're doing. Otherwise, when you grab the cable and let it go...ususally it is "trained" by age to go near where it was plugged in when you drop it. It will often even tell you which way to plug it in the same sense. Look around where it drops for a pin terminal/receptical that is as wide. I can't tell from your description if it is a flat cable or a ribbon cable with a molex end, or a ribbon cable with a pin header end. Any way you slice it though, there is only one place it will fit and has the same number of pins.
@@peterlamont647 Problem is that I gave it to local computer guy to fix. He not only didn't even get the belt, he's the one who disconnected the flat white plastic cable. I'll take another run at it. Thanks
Thanks a lot. My Sherwood CD-5090R CD player works again :) Thanks, thanks..... You are a GENIUS!
Definitely helped! Did just what you said and it works perfect! Thank you!
Thank you. I just brought an old nad C521i cd player back to life.
Hi, couldn't tell if you adjusted the potentiometer clock or counterclockwise. Which is it? Thanks
Thanks for your video, it really helps in repairing Dvd player !
Thank you very much for sharing! My 15 yo Sony DVD player came back to live!
Thank you. Worked a treat on my Pioneer Blu Ray player!
Excellent!
That was a very informative video. How long did the DVD/CD player work after the fix?
Thanks! Still works today
I have a vintage Samsung Progressive Scan DVD-P231 DVD player, and the unit did not have any of the trimmer pots that was shown in your video. Anyways, all that I did yesterday was to get my small extra fine relay contact file, and shine up some of the ribbon cable contactors that were coming out of the DVD assembly. In addition, I had previously checked some of the larger capacitors in the power supply and checked a couple of capacitors on the logic board. Well, they all tested out okay. Actually, it could very well be that the unit simply has a weak DVD laser diode, but it looks like there isn't much that I can do about that. Yes, I had previously lubricated the spindle motor, and cleaned the laser diodes. The Samsung Progressive Scan DVD-P231 did play a full movie afterwards without interruptions, but I'm crossing my fingers as I did have regular problems with the video freezing at times. Thanks for the video!
Thanks for sharing with us. May I ask you something? Is there any spot on the board where you can take some measurement in order to be as accurate as possible? How can I identify it in different boards?
I commend you both for your persistence and for your assistance. Thank you.
Fantastic sir thankyou.this will help me to fix my friends DVD recorder.
This trick fixed my old school Alpine 6-disc changer, model CHA-S604. Bought the changer brand new way back '97 and lately I thought I would toss it to the bin. Cleaning the pickup lens the previous years was fine but it was just lately that it fails to read any discs anymore :( I measured the resistance on the VR POT before turning from 650 ohms down to 640 ohms. Merely a 10 ohms reduction. Now the unit plays like a champ! Thanks a ton!
good info on the pots. I've had success by just cleaning & reseating the ribbon cable also.
Good tips thank you very much my LG CD player had same issue .now it's working.thanks a lot .
Thanks for the advice. What screwdriver head would those pot controls normally be?
I cleaned mine and it worked! Thank you
Wow amazing! It worked
Great-Thanks for Sharing...
I cleaned the Eye on Mine awhile back, that did the Trick.
But this Added bit of Knowledge, will Certainly Help!
Just a little tip- listen to the servo head drive, over adjusting will cause noise from instability in servo gain amps. Backing off to reduce noise will extend life by reducing temperature in the laser head. Every 10 degrees (C) rise halves the laser life.
I have no idea what I'm doing, but do you think cold weather can break a player? My dvd player broke and I wonder if it's related to the apartment being too cold. Or the dvd player being too close to the front door while it's record breaking cold temperatures outside.
Thank you so much, after obviously cleaning the laser which didn't work, I then tried your suggestion on my lovely old Japanese made JVC UX-T100 micro hi-fi and it worked a treat. This little gem sounds sooo good.👍🎉
Thnk you for the video...I am kind of a beginner with all the electronics and stuff...would you PLZ explain to me what woud measuring the resistance tell you...I didn't really get it...thx again!
VERY HELPFUL !!! Thank you for the wisdom.
'Working"
Thanks a mille man!
Best regards from Belgium
My DVD player shows the same problem.Thanks for sharing the information.
Thank you very much, this solution worked perfectly on my Kenwood 5 CD player. (model 103 CD). I had to remove the back panel in order to access the little screw used to fine tune the diode.
I meant the potentiometer, not the diode :)
I have watched several of your videos. I have RV stereo entertainment system. Everything works except the CD/DVD drive freezes/skips on all discs( never tried regular CD) after cleaning checking belts still no luck. I finally just pulled out that component and have DVD player hooked into system with AV cords. I have the drive out in multiple pieces. This does not have a tray that opens an closes. Do you have any suggestions? I would like to just replace the whole DVD component ( that drive/box is easy enough to remove from the stereo) I have very basic Jansen AW60 not looking to upgrade. We get zero service camping so just need to play occasional DVD for kids
Thanks friend! I lucked out; the Qtip on the laser was all it took to get my old laptop to read disks again.
Hi Dude. Are you around? Looks like you haven't answered quite a few questions put to you. I have a Sony Home theatre DZ370 more than 22 years old. The CD/DVD player displays either ' Cannot play disc' or ' No disc' . Never opened the unit. What's the least invasive way to repair it?
Sorry been really busy lately. You can try one of those cd laser cleaner discs but i've never had much luck with those. Other than that you'd have to open it up.
Thanks man, fixed my cd player thanks to this video!
Thanks man, worked perfectly on my Sony CD. It was dead since the 90s. Cheers!
Thanks dude; worked like a charm adjusting those pots. Rock On!
thanks man, Just fixed my toshiba xr-9217 cd player using this method.
I'll give the dirty lens a try. Yamaha SACD player out of warrantee and two years old. Wish I had bought the extended warrantee offered by Amazon. Sending to an electronic repair shop is a hassle. Thanks for the video.
I used a can of compressed air and sprayed it into the open CD slot and fixed mine just now. Thx.
alcohol?
This worked for me and I learned so much - thank you 🙏
in my experience this fix works for older electronics . 90%of disc players i repair its the spindle motor that goes bad not spinning at the right rpm replacing it does the trick if the pot adjustment doesnt work. this is due to the fact that everything now is made cheap and designed to fail
I haven't done this before, but I wanted a nice player cheap, so got a player that does not read and also a new lens, thinking that is what it takes, but now I am not so sure anymore :) Hope it's not the motor now ! This is an ONIX SACD 15 I got for 150 Euros, hopefully not an expensive paper weight.
@@Baerchenization well you already bought the player and lens . I suggest you go through with your original plan and see if that does the trick. You might get lucky. If not at least you know what the problem is not.
@@flashgordon1695 Well, there is news :) I found a video where someone replaces the same laser unit; turns out that you have to de-solder a little blob first and I don't have the means to do that. So I found a guy who fixes them professionally and he said that replacing the laser only on this unit is a hatchet job and I would need the entire assembly. So I got that and it was even cheaper than the laser only. Anyway, swapping the laser assembly did not do the trick and he had no immediate solution. Now, I have paid 150 for the unit, 2x ca 40 for the lasers, 50 shipping for the CD player and the repair guy has upped his estimate to 200... and I already drove out there three times, which is ca 25 miles from where I live... not going so great, eh :) Oh, and the seller forgot to send the remote control and of course never bothered again. He is in France, I am not, so that it that.
@@Baerchenization Well, on the bright side, once it is repaired, it will work for many, many years.
This video is very valuable! 😊
Man a q tip and a little vinegar worked perfectly thanks!
Hoping you might have an idea for me here! My CD changer reads a lens cleaning CD with bristles on it (it plays back music while cleaning) but not my regular CDs. Any idea why this might be the case?
are those regular cds, cd-r's or burnt cd's by chance?
@@Electronicle just regular store bought CDs!
My Denon works again! Thanks a million!
Hi, for synchron with Multimeter (Ohmmeter) how much has to be the resistor in this case??
Wow! You're a genuine genie genius. I have a laptop that is being hit or miss about reading disks, so I am having a hit or miss time in installing the operating system. I have to use the CD/DVD way because its USBs aren't for bootable disks. It's an old laptop. It was working fine at the beginning and that's how I installed an operating system on it, but I want to add another operating system because I haven't gotten the first operating system to access WiFi; it is a Linux operating system and I'm not well versed on it. So I am going to try a partition with good old Windows 10, but the CD/DVD device is being difficult. I was thinking of buying one like it on eBay for only 7 dollars, but I decided to try cleaning it and wiggling it a little and it came back to work but it ran halfway for the WIndows 10 installation disk, it stopped spinning leaving the Windows logo, and it had not done loading all the installation utility to RAM. So, that's what motivated me to look around for ideas on how to fix these mechanisms.
Thanks for the video. This is exactly my problem but I can't locate my trimmer pots nor find any reference to them in the service manual. Its a Marantz CD57 (IE Phillips era), the tray is still marked Phillips but the ribbon cable comes in at the side, not the rear. In service mode P01 I get Err 02 which is a focus error but I'm not seeing any light at all from the laser - would you expect to see something? Are there always trimmer pots? will they be hidden somewhere the tray or could they be on a board? Thanks.
Great video. Do the same rules apply with a blu-ray player?
Good info, I had few old panasonic cd players that don't read the cd-rw, fortunately I have all the tools and meters to play around so giving it a shot! Not sure if CD-RW support is barred from the chip or at the laser level... 🤞
Update: Nah, didn't work, it's already 20yrs old, didn't want to stress the laser more, it was 8.21 Khz , move it up to 9+ something, then turned back to 8.22 Khz (the variable resistor is very tiny) :P
well worth the try anyways. Thanks for the update!
Thank you.
Thanks to you, CDP has been repaired.
Question? I'm planning to buy a shanling cd-s100 cd player, and I found out that I could buy, original remplacement optical laser lens.
Would it be a good investment?, the day that I have a problem with my cd player, I could simply replace the laser lens. Wouldn't that extend my cd player for a longtime use instead of buying a new one?
Nice, thanks, it work after this, i tried to clean it a milion times and that did not do the trick, so thank you for your video
Awesome video!! Totally agree with everything you said. Thanks for your honesty.
Just took it apart and it worked. Thanks!
Apologise for going off Topic but I was wondering do you happen to know which components are likely to be responsible for the Dynamics within a sound stage?
I have a question, i have a kenwood RXD-500 and this thing has a 3 disk drive, so i opened it up and the laser was under a layer of dust. I cleaned it like u did and i did the pot thing. It didn’t work.
It seems to be a common problem with this cd player :/
I hope you can help me
Thank you with your suggestion I repaired a SL-PG390 Technics (mechanic Philips CDM 12.1) , I have to dismount the whole mechanic, remove the electronic below of the CD mechanics and the trimmer is just below the laser. Trimmed a little more on the right and tadaaaaa.
To save chancing getting the presets out of alinment,perhaps try Servicesol (or the like) electric contact , electric clening fluid! Cover all parts with toilet paper to stop the spray from going anywere except for the presets and give a couple of short bursts ( keep the spray can as vertical as possible ) level for 10 minutes to dry and it should work fine! If it still doesn't work then chances are the fault lies elsewhere! You could try looking for other pre sets and spray them! If that doesn't work, then disconnect all the ribon cables (as in the video ) and spray the sockets were they came from !
Thank you man.I have Yamada dvd player and it has the same problem I thought the.motor is the problem.
Hey Electronicle,
Great video. I have an old Koss DVD player, but for some reason I wasn't able to turn those screws that you're talking about. Any ideas, or am I just looking in the wrong spot? I couldn't find anything else that looked similar to the screws in your video besides what I was already looking at. Would really appreciate the help
might not be adjustable on your model. You can check any other boards that are in the area (ie connected via the ribbon cable that goes to the pickup assembly)..but dont just turn things without knowing for sure what they do. In this case a service manual comes in handy.
Thanks man. I will give it a try with my broken sony cdp 395. take care. Stay safe.
Is it possible that I have the same problem as you do in a brand newly bought TEAC hifi system? Or is there another cause seeing as the device is brand new?
