I know this is 5 years old, but I can not thank you enough, you just rescued my Pioneer CD player/Recorder. So Easy to follow, even I managed it without killing myself in the process.
I picked up a Denon DCD-615 from Goodwill recently and it had the exact same issue. Watched your video, applied contact cleaner to the switch and the issue was fixed immediately. Thanks!
Seven years later your video is still delivering great value! I had done this fix before but had totally forgotten what I did. The problem came back recently so this was a fantastic refresher. You sure know your stuff! Lots of great tips. The top about tray position at reassembly time is great to know. I can't wait to see if my Denon DCD-3000 is actually a Sanyo! Thanks for the fantastic video.
I just purchased this unit from an estate sale. It had the exact same issue. With the help of your video I just fixed it. Now it's running like new. Thank you so much for posting videos like this. I have no background in fixing electronics but I love to tinker & fix things myself. Love to work with my hands. With the guidance of this video I was able to save me some $$$ & get the satisfaction of doing it myself. Cheers!
Thanks. That is the point in these videos. Also why I try to use common tools, not fancy lab grade, or professional shop tools. The type that the average hobbyist might have. I spent the past 35 years repairing equipment, 20 of those years I did it for a living, and today it is just for the satisfaction of keeping the old technology working. Most of this stuff is pretty simple, and with a little help many have fixed their own stuff.
Fabulous video! Seems obvious once you realise that the position switch is the culprit. My 23-year-old Denon is now in prime condition, thanks to your help.
I had the same problem with my old Pioneer Elite DVD-Audio player. I paid big bucks for the player, so I was hesitant to replace it with another player. By watching your video tutorial, I managed to fix the problem. My DVD tray works like a charm! Thanks much!
Pioneer DVD player drawer fixed. The tray wouldn't stay open as in this video. Your video, a can of DeOxit and some patience on my part resulted in player drawer now working as it should. Without this video, I had no clue what to do. Thanks again!
WOW , just experienced this with my Sony bdm 350, tray kept opening not loading disc. Did a search and found this video. I have my player back again. Thank You for posting. Cheers.
Many thanks for the good explanation! I had the same 'tray opens and immediately closes' issue with my Rotel RCD06 (which is actually a Sony KSS 213-CL). The assembly of the Rotel is a bit different from the Denon in your video, but the principles are the same (interestingly the Rotel drive has two mechanical switches instead of one; maybe one for detecting the open position and one for detecting the close position?). I used your instructions to fix my CD player and now the tray opens/closes and stays in the required position as it should. I am very happy I can safely drop a CD in the tray again, as with this problem I horrendously scratched one of my favourite Miles Davis CDs (Bitches Brew). From the money I saved by not buying a new CD player or having it fixed it at a shop I will replace the Bitches Brew CD ;-) Thanks!!!
btw, Thank you for this. I have the same old denon player and it had the same exact issue. It's back to working well again. The issue of the tray going out and right back in actually started like 20 years ago, lol, but it only stopped reading discs recently. It's great to have it back in good order, since it's a classic player and hard to replace.
Yep, I have a DCD-800. Looks almost exactly the same inside. Same transport, same Sony chips and the board is very similar.. Got it for a song because it skipped a bit. Turns out all it needed was a good cleaning. Works like a charm and sounds great.
I've just repaired Yamaha DVD-S663 having the same problem. The mechanism is different, but the concept is similar and the switch looks exactly the same. Thank you for this movie, it helped me find the solution quicker.
I have a Denon DCD-1650AR with the same problem. Appeared to have an identical drive mechanism. Your video was a perfect guideline for a successfull repair. Thanks so much!
There are two trim pots at the back near the phono rca output, what are they for mate? i know the other 2 next to the player assembly itself are for tracking, but not sure what the other 2 are for?
this is one of the best home CD players ever made, since it has a remote with volume control, a feature almost no affordable CD players have. A must for people that use power amps instead of cheapo receivers
Thank you very much for this very informative, and enlightening demonstration video, 12voltvids! Maybe that problem is what is not happening with this AMC CD-6 CD Player (of 1992) I bought that's in very good condition, but it won't eject the CD Tray! That open, and quick close operation only happened to me a couple of times; the Denon DN-600F CD Player I bought used works well, built like a tank. I very recently made a mistake about buying an AMC CD-6 CD Player from ebay seller that does not know about hi fi audio, or electronics. I bought an AMC CD-6 (of 1992) that looks in very good condition; but does not work! Wasted money, and work setting it up, opening up the case, the CD Tray could be broken! However, lately I bought a Denon DN-600F CD Player (of 1998) that looks beaten up; scratched, flanges are sawed off, those 2 machine screws on each of the two sides are missing, top front is taped down with a red tape, and a bit dirty, but it plays back a CD very well! Furthermore, Functions function, too. By the way, it's good you mentioned about static electricity; I was wondering about that topic. I wore an anti-static wrist strap when I upgraded my personal computer. Finally, I may be able to repair this AMC CD-6 Tray eject problem that's a reject; but I'll get an experienced, expert technician to make the repair. By way, don't you have to be careful of the light from any laser lens assembly?🔉🎵🎶
I once bought a Denon CD-R-W1500 and there wasn’t allot wrong with it so I decided to see if I could use its CD-R Drive as it did have a few problems but mainly fixed, and had like the jog wheel button missing. It looked as if it was dropped but still works fine. Anyway I tried it’s drive in my slightly faulty Marantz CD Recorder only to then realise it didn’t really fit. So I ordered one from Instrumental Parts in the US. As I’m from the UK so had a job to get one. I replaced its old drive and managed to successfully fix it. Now I have my Denon one with a stuck drive but couldn’t find its switch to re-open it. Is it in the same place as this one or somewhere else? As this one looks otherwise the same sort of drive. Thanks for the help I’ll give it another go sometime and may sell it in future due to being happy with my, portable CD Recorder which is a Superscope PSD340. I discovered the Denon drive is slightly too high but with the right numbered model of drive it is excellent!! I even recorded a CD for my Sister and Brother in Law.
Do you prefer those “single beam” optical units or the three beam types? I read that single beams are more precise and tolerates scratched disks better than 3 beams, but single beams tracks more slowly
I have the denon dcd715 one with the pitch control, tbh its the best cd player ive ever owned the sound is razor sharp, mine had exactly the same fault, turned out it was just a dirty motherboard connector. the brown one.
I have a Sony® CDR-W33 recorder that had a similar open/close problem; however, my issue turned out to be a stretched belt on the pulleys that operate the disc tray.
The way in which you say " out" means a previous incarnation had to be a bailiff. You can use standard music youtube without rights. Keep it up good work, thanks. 8)
Has anyone ever done a video for a Denon CDR-W1500 on how to fix the draws on that? Would the switch be located in the same or similar place or are they all different? As I did find some don’t fit others and I tried it in a Marantz CDR340 which didn’t fix and I live in the UK so I ordered one from Instrumental Parts in the US. I then was able to fix that one and even got it working with the front panel back on the CD-R drawer. But I gave up on the Denon Recorder I bought due to not seeing the switch anywhere, so it’s now temporarily in our loft in a box. Please feel free to help!!
I have a DCD-800 unit. I'm trying to get the CD unit out to clean it, as you did, but one of the screws is under the CD tray rail and i can't access it. Any hints?
I came across a denon dcd 615, looks very similar to this one. After opening it I noticed how filthy it was. The disc tray jams sometimes and it looks like they dropped some sort of liquid on it. The inside is all sticky. The pcb and everything else. I was thinking just using ip alcohol on the whole thing but I’m not so sure
My aiwa CD player won't hold a cd when I close the drawer just pops it open, I've opened it up and it looks like (I'm no expert) the mechanism isn't fully pushing the lens carriage all the way up...can anyone help?
Nice and easy one for a change :-D It focused quickly so that laser/settings must be spot on. Ive had computer cd/dvd writers with similar bad switches, toshiba comes to mind. Also crappy belts not gripping cause more trays to fail, and laser death :-(. The main pcb electronics is normally ok.
Nicely explained. Can you suggest me the remedy of my music system Philip's DVD+CD+TAPE Recorder and AM/FM Receiver,in which the loader tray is not opening in case of DVDplayer in spite of showing open,close and reading digitally,without physical function. What to do? Thanks.
I have an Aiwa unit with almost the same Sony optical pickup as this, just mine had a dust cover and only one pot on the board. Kss 213 I think. Mine skips though. A lot of stuff could be wrong with that thing, it uses poor quality capacitors.
Thanks for sharing. This should come in handy. How about ones where you hit eject and the tray won't open? I've had several desktop computers do this and I can't figure out why. I hear it wants to move and the light blinks a few times, but that's it. See you in the next one...
+Darryl 603 Check out the BOSE 321 system DVD repair. That one wouldn't, open right or close right. It is either a slipping belt, or in the case of a direct drive, one of the gears has a crack, probably on the motor shaft. When people shove the disk tray in as opposed to pressing the open/close button, they stress the plastic gears, and eventually they break.
I have a Pioneer DV-530 in my bedroom and it has the exact problem like your Denon. Every time I press the eject button, the disc tray opens but won't stay open and retracts at the end. I don't have a chance to insert the disc. Sometimes if I give a pull on the tray when it opens and reaches the end, it will stops and stays open. Very strange! I have no electronics knowledge but thinks if there is a transistor controlling its movement? After I watch your video, it gives me a clue that maybe Pioneer DV-530 has a similar switch causing the same problem.
To 12voltvids I have a DVD player which is an all region player it did work today but I play it all and at the end of the disc when done I put in another disc and it says no disc so I looked at it the tray opens and closes I check the motors they do turn but the disc motor spins and stops the laser head assembly moves a little like it should I did check the switches their ok. one micro chip has a heat sink on it and gets very warm but two transistors get almost hot can a bad capacitor or more of them cause this to not work like this.im sure you worked on DVD players.its a supersonic DVD player all region.do you know what's wrong and to help me please at least tell me what could be wrong with it.since you know how to repair electronics.thanks let me know soon.but it is a small player.i do need your help if you know what's wrong.thanks.
Hello Sir, I have exactly the same Denon DVD615. Disc mechanism seems normal. My problem is those buttons and screen are freezing after I inserted CD. like "00 00m 00s" and the small tracks number are on. What do you think of this problem? Sorry for my english.
+12 voltvids Do 3 disc carousel cd players have these switches too?my sharp all in 1 stereo has been opening/closing by itself & now it has 3 cds stuck inside,atm front panel cd buttons are unresponsive & 3disc tray wont open @ all . Lcd display says ER (error) could this b the tray switch as u suggest in video thats causing the error & other problems too?
Hi, I have a Denon RCD M41, I bought this in june 2020, since yesterday the bluetooth fails, I can't connect it, do you know any solution? Thanks in advance.
thank you for explain everything, you are a pro no doudt ! i want to ask i have cd player YAMAHA solid one and i would like to fix it the drew is stocked ... is it tottaly safe to open it when its OFF ? i'm talking about the laser beam eye , radiation what ever . thank you !
There is no laser radiation unless a disk is in and it is playing. Also the laser radiation will not harm you unless you are using optical instruments to focus it into your eyes.
Didn't almost every pick-up laser used the 3 beam method?, as far as I know the only ones that used the single beam were those Philips/Magnavox that used the swing-arm mechanism.
12voltvids You sure?, because I've seen quite a few detectors from various Technics/Panasonic CD players and all of them had an 8 pin detector, 6 pins for A ,B, C, D, E and F and 2 common pins, while Philips ones only had ABCD. In fact, I think I still have the detector from a Technics SL-P116 (that I killed by mistake) which was one of those FF-1 and I think it had an 8 pin detector, it would be a 6 pin one if it only used a single beam, but I can't be sure until I find it.
+Gordon Freeman I'm only going by the literature that was in the service manuals at the time. I really didn't care personally one way of the other because from a service perspective all that matters is if the eye pattern is correct. The service literature used to claim that it was a single beam system on some, not all of their designs. I probably still have some of those manuals around here, as I had many of them.
12voltvids Well, maybe you have some information that I've never seen, most of the books and magazines I have about CD player theory of operation mention and assume a 3 beam system, I only heard about the single beam like 10 years ago. I don't know which system is better though, but yeah, I agree, that might not be of importance, but I always found CD players amazing devices, the old ones at least, newer stuff was boring to open and not much to adjust, I could spend hours looking at the eye pattern though, for me is a simple yet pretty waveform.
+Gordon Freeman I think that some of the confusion is also that Panasonic used some existing pickup chips that had the side sensors but they weren't connected because they claimed that their digital focus an tracking servo was so accurate that they didn't need them. But they just use off the shelf pickups a if you look at the schematic for the ff1 players the 2 side detectors are n/c to the servo. This kept costs down because some designs did use them. This is not uncommon. I had a beautiful old slp50 I think the model was. Single disk, big vu meters. Broadcast unit. I was offered 600 for it, so I took the money and run.
There are all kinds of contact cleaners available. You can wash our with99% isopropyl which will clean but contact cleaners have lubricants they leave behind. So I would recommend using the proper stuff.
I just want to say up front. Back in the day, nothing made me cringe more. Than watching someone push their cd or cumputer disc tray closed. You pay all that money. They give you a nice interface to operate your new expensive equipment. Then just treat it like a barbarian and jam the tray closed. 🤯🤪
@@12voltvids Maybe something else was the cause. Because, those guys always seemed to have trays that worked poorly and/or noisily. Probably because they didn't just push it like a button. They would literally shove the thing shot. At least half of the way.
@@12voltvids Btw. Thanks for the video. I recently got a pioneer CD player that is having this exact issue with the drawer opening and closing right away. Glad to see it's such a simple fix.
I know this is 5 years old, but I can not thank you enough, you just rescued my Pioneer CD player/Recorder. So Easy to follow, even I managed it without killing myself in the process.

Didn't almost every pick-up laser used the 3 beam method?, as far as I know the only ones that used the single beam were those Philips/Magnavox that used the swing-arm mechanism.
+Gordon Freeman Panasonic / Technics used a single beam. They called it ff1 fine focus 1 Beam.

You sure?, because I've seen quite a few detectors from various Technics/Panasonic CD players and all of them had an 8 pin detector, 6 pins for A ,B, C, D, E and F and 2 common pins, while Philips ones only had ABCD.
In fact, I think I still have the detector from a Technics SL-P116 (that I killed by mistake) which was one of those FF-1 and I think it had an 8 pin detector, it would be a 6 pin one if it only used a single beam, but I can't be sure until I find it.
+Gordon Freeman I'm only going by the literature that was in the service manuals at the time. I really didn't care personally one way of the other because from a service perspective all that matters is if the eye pattern is correct. The service literature used to claim that it was a single beam system on some, not all of their designs. I probably still have some of those manuals around here, as I had many of them.

Well, maybe you have some information that I've never seen, most of the books and magazines I have about CD player theory of operation mention and assume a 3 beam system, I only heard about the single beam like 10 years ago.
I don't know which system is better though, but yeah, I agree, that might not be of importance, but I always found CD players amazing devices, the old ones at least, newer stuff was boring to open and not much to adjust, I could spend hours looking at the eye pattern though, for me is a simple yet pretty waveform.

I think that some of the confusion is also that Panasonic used some existing pickup chips that had the side sensors but they weren't connected because they claimed that their digital focus an tracking servo was so accurate that they didn't need them. But they just use off the shelf pickups a if you look at the schematic for the ff1 players the 2 side detectors are n/c to the servo. This kept costs down because some designs did use them. This is not uncommon. I had a beautiful old slp50 I think the model was. Single disk, big vu meters. Broadcast unit. I was offered 600 for it, so I took the money and run.
tnx excellent.
Can you use something besides contact cleaner?
There are all kinds of contact cleaners available. You can wash our with99% isopropyl which will clean but contact cleaners have lubricants they leave behind. So I would recommend using the proper stuff.

I just wiped it with some rubbing alcohol and now the tray won't move at all
nice
I bet your better off spraying that on food than cheese wiz
Cheese whiz? Do they still make that?
Do you have a facebook or email address, I'd like to show you a 30 second video of what's wrong with my sony tray.
Tell your address my dvd player problem is there sir
hmmm, Sony = Denon, who woulda thought? what isn't rebadged these days?
I just want to say up front. Back in the day, nothing made me cringe more. Than watching someone push their cd or cumputer disc tray closed. You pay all that money. They give you a nice interface to operate your new expensive equipment. Then just treat it like a barbarian and jam the tray closed. 🤯🤪
They are meant to be pushed closed. There is a micro switch that detects the slight movement which triggers the load.
@@12voltvids Maybe something else was the cause. Because, those guys always seemed to have trays that worked poorly and/or noisily. Probably because they didn't just push it like a button. They would literally shove the thing shot. At least half of the way.
@@12voltvids Btw. Thanks for the video. I recently got a pioneer CD player that is having this exact issue with the drawer opening and closing right away. Glad to see it's such a simple fix.
