Spilled coffee from my desk onto my Pioneer DDJ-REV1 and using your video to take mine apart to get rid of this coffee spell and clean this mess up! EDIT: I'm now done and got plenty of wet coffee off of my sample buttons. I used 70% alcohol wipes and some q-tips on the board where I noticed coffee and rinsed the plastic/ rubber buttons off with natural soap and allowed to completely dry before putting back in the unit. This video was a life-saver, especially for the cross fader buttons which I would have had no idea on how to take off. I was able to remove most of the knobs using a mini-screwdriver (think eyeglass screwdriver) and wrapping a used alcohol wipe around the tip so it wouldn't scratch the plastic case. They were pretty stuck so I also used a rubber jar lid remover to grip them and pull up vertically - no doubt your hand will hurt a bit when completed. I suggest anyone who takes apart their electronics to take plenty of clear photos before removing screws, etc. so you have a reference where it all goes back.
Thank you so much for this…. Just replaced my main board and it was great going into it knowing what I was getting into! £60 for a new main board off eBay… £200 on a new controller saved!😊
Thanks for the tear down. A bit more info on the headphone jack and how easy it is to replace would have been fab but I guess I will have to figure it out for myself. Great help to see how to take it all apart though. Thank you 😊
Let me know how you get on. I just took a unit on with a few functions on the left, like the cue, not working. I suspect that left hand board. Interested to know how you get on as we're both on it at the same time! Apparently a cat pissed on it xD
@@Kholaslittlespot1 as it turns out the owner decided to return it instead, but I'll save this video for if I ever get into similar problems with my own :)
Hi there... would you consider doing a teardown of the DDJ-FLX4 and possibly compare it to the DDJ-400? (the FLX4 is the successor to the--now discontinued--DDJ-400. thx!
Nice to still see the larger board being built single-sided. Probably a cost reduction function, but would definitely take flex better when the controller is getting banged around in a bag or travel gear when gigging out from place-to-place.
At 25:25 you show two photo interrupters. one side of each interupter is a IR LED and the opposite side is a IR photo transistor that detects the InfraRed light. The black 'fingers' in that disc passes between the two halfs of the interupter and breaks the IR beam as they pass through.. The system knows what direction the disc is turning by seeing which one of the two photo interupters has it's beam broken first. That is why there are two interupters fitted. The speed can be worked out by how fast the Infra Red beams are being broken 'interupted'. Does this make sense or am I rambling?
Nice job! 👍 Now I don't have to pick mine apart to find out how it looks like inside. But probably will at some point. Been thinking about how to make my crossfader feel smoother.
Saved my ass bro! Thanks for posting this. BTW if you just need to get to the main USB board, there's no need to go through taking all the fader caps, and knobs off.
I have a problem with my DDJ-400, one of the tempo faders not working, I am thinking about replace it but i dont really know how can i find the exact same model. Can you tell me what is the model number? Thank you man from VENEZUELA. Wish you the best!
How easy is it to replace a tempo/pitch fader on this? I'm good at soldering, but don't really see how that fader is attached. Was it just the two solder spots at the top and bottom of the fader? Cuz that'd be awesome
Slider caps have locking mechs, huh? Totally would have broken them by just pulling vertically up. That’s some good info to know. Good idea with key puller, too.
I only discovered the locking mechanism when I couldn't work out why pulling straight up didn't work - glad I didn't keep pulling and went off to look up how to remove them.
Thanks! I used this video to fix my controller. It turns out that cat hair was clogging the jog wheel optical sensors which prevented any movement from registering. I can't believe it.....
Out of itnerest would it be easy to open this up and remove boards in tac so I can get to front panel to clean out the gear from a dust storm at a gig.
So here I am with my skinned ddj400 full of beer. Because ofcourse. (Please pioneer, make next one ip47, you know where these are used - beer and rain.) Suggestion - add some words in good practice to remove fluids inside. I wipe with water and blow dry with hairdryer. I’ll let you know if I manage to save it. 😅
Hey, thanks for such an informative video. I used it to replace my 3.5mm jack. The new one works great but for some reason now I'm having an issue wherein the output from my DDJ400 is so so quiet it's almost silent, I can just about hear it with the track and speakers turned up full whack. Is there a relation between the two circuit boards? Perhaps I've fixed one thing and broken another...
Thanks for this video, Cameron. The last time I watched one of yours was the Sun SparcStation! Anyway, my Mixtrack Pro II has been damaged due to minor (but fatal) water ingress, affecting the optical element. I had no idea what to search for on Mouser, and the comments have identified it correctly! Apparently it's a photo interrupter, or optical switch, or optical transistor. I hope it works...
A minha estava funcionando normalmente desliguei e aguardei. Assim Que Liguei Novamente Ela Apresentou Algumas Teclas Sem funcionar, Apenas o lado Direito como ( Cue, Beat Sync, Fx , Load ) Tem Alguma posição De Que Possa Ser ?
I guess the links next to the board version might be used by an automatic testing in manufacturing. So they might have the same board in different products, but populated slightly differently, and the link tells the tester what components (and values?) to check for‽
If the components are inserted by machine, then using a wire link to label the model number means they can have the same machine add the model number label. That will avoid an extra process step and pretty much eliminate the kind of error where a board with the components for one model number gets labelled as a different model number, or where a pre-labelled board gets populated with components for a different model number. Even if they are assembled by hand, it makes sense for the person populating the components to label the board, to reduce the chances of the same kind of errors.
Thanks for a great video. I got beer go through my left side. The bpm match button doesn’t work anymore but the light still works. Should I let it dry or take it open?
As long as you're confident enough I'd definitely pop it open and get the board out to properly clean it, isopropyl alcohol would be fine to clean it off. Cleaning it alone may me enough to fix the button (maybe some contact cleaner sprayed into the switch as well) but what you really want to avoid is the liquid causing any further corrosion to the board which is much harder to repair than a faulty switch.
@@camerongray1515Thank you so much man. Had a house party last night and some ignorant people were messing around. Really frustrating. Will see what happens!
Ahhhhh.... this is making so much sense. I'm commenting early but I'm having issues on the left deck of a unit I've been given, about 85% functionality, so it's suddenly clicking it's a separate board on the left. Hopefully I can clean it up or find a replacement board/s. edit- also the headphone jack may be screwed. 'Feline liquid damage', apparently xD
Hello fter using it with a power adapter un ipad i got now power at all on ddj 400 no reaction i tested on pc still no react have you any ideas what could it be? Much appreciate
Does anyone know what i could try to do in order to fix my volume fader? I'm scared to open the whole controller because i'm scared to screw it all completeley. Is it possible to this as a fool or should i contact some specialist?
Hi Cameron very interesting video . I’m wanting to interrupt the audio from each cDj section before it enters the mixer , export it with some soldering to rca output for an external mixer . Do you think this is possible?
Not really on something like this - this is a basic controller where the mixer section is just a control surface that controls the software, it's not a complete hardware mixer. To do what you're needing, you'd be best to get a 4 channel USB audio interface that works with Rekordbox and configure the output settings to send the audio from each deck to separate outputs. You'd then connect this interface into your mixer.
Unfortunately not, the "mixer" is purely a control surface, there is no physical mixer in the DDJ 400. Higher end controllers such as the DDJ-1000 (which I also did a teardown video of) do contain a real mixer, however it's still a digital mixer and therefore doesn't have any analogue audio passing through it. Your best bet is to use an external audio interface.
As far as I'm aware they're all actual pots except for the browse knob which is a standard rotary encoder. Since they are ultimately controlling audio levels, you would really need the analogue linearity of a potentiometer - an absolute position encoder would produce more of a "stepped" output which would be noticeable in the audio. Looking around it seems as though you can get 4 pin potentiometers, some of them use the fourth pin as a centre tap, others simply have the fourth pin but it's not connected to anything.
Me too! Unfortunately someone poured some liquor into my controller but it continued playing on well till the next morning, only to realize one of the volume slides ain’t working fully! Unless I push it all the way up, there will be no audio whatsoever! Did you manage to find a solution? Thanks
@@JasonKrueger I had to contact the Numark support center and they asked me to ship it back to them, luckily enough, they sent me a new controller 😎😅!!
Hey Cameron Grey, thanks heaps for this great teardown. Always a brave mission to take apart something like this, you never know if it's going to go back together smoothly until it's too late. Turned out to be alright! I'm not sure of how much electrical understanding you have, this is the first video on your channel I've seen. But you did excellent in regards to intuition and research understanding the board and how it works. I found it very helpful, as if I had teared down one myself. The only thing I didn't see that I'd have liked to is how is the capacitive touch electrically coupled to the rotating platter. I assume it's either a cheap metal clamp around the shaft, or a carbon brush like a motor. But couldn't tell from the video. Thanks again!
They carry out a similar task to a traditional rotary encoder but they use optical sensing rather than any sort of physical contact mechanism in order to reduce wear and drag. This particular model doesn't really have any DSP capability, all audio processing is done in software on the connected computer, the controller simply acts as an audio interface. However, some of their higher end controllers (DDJ-1000.etc) do have integrated digital mixers that carry out the effects in hardware.
My crossfader has snapped and needs replacing but I don't have a clue about soldering etc. Is it a quick swap or do I need to know some electronic stuff? (which I don't) 😂
While I'm very familiar with the physics behind electronics and communications, I cannot for the life of me figure out how circuitry this complicated works! Any recommendations for articles/journals/books/courses that I could pick up?? My browse wheel is just randomly skipping songs on the playlist, thought it was a software problem and tried downgrading Rekordbox and my OSX but it wasn't that. Gonna take it apart in the hope it's just dust making it act up, maybe static electricity?
I'm definitely not an electronics expert, most of my knowledge is just pieced together over the years, TH-cam channels such as bigclivedotcom and eevblog could be a good start though. As for your browse knob, it's probably a "rotary encoder" (en.wikipedia.org/wiki/Rotary_encoder#Standard_binary_encoding), as a first port of call I'd try cleaning it with some contact cleaner spray as it may just have dirt/corrosion in it. If this doesn't help, I'd check all of the solder joints on it to make sure none of them are broken and if they look okay, I'd see if I can find a suitable replacement part and replace it (you may be able to find a brand and part number on the part)
hi cameron hope you can help i spilled a drink in my controller i cleaned it out and now my right jog wheel is spinning like a fidgit spinner lol do you know what the sticky grease is called that goes on the jog wheel shaft hope someone can help
I've done most of them, still got to do the kitchen, hallway and shaver socket but keep finding more interesting things to spend almost £300 on - The kitchen gets pretty expensive factoring in all the grid switches and cooker isolator. Might do them soon since I'm not spending nearly as much with the current lockdown but I also need to budget for other things like replacing the expiring smoke detection.
While I'd love to do more teardowns of stuff like this, I only have access to equipment that I own myself and these teardowns sadly don't generate enough revenue to justify the cost of buying equipment to teardown.
@@camerongray1515 It would be interesting as they appear to share the same pitch adj component but the FLX6 has a higher pitch accuracy in Rekordbox than the 400. The FLX6 is able to get every increment but, the 400 is just shy about 0.02 BPM out. Still accurate, just not as accurate. I have electronics education /knowledge & service my own Pioneer Mixers & CDJs but, I won't look & ruin the warranty on them until I need to 🤣
My DDJ 400 recently developed a fault: When I put my left deck's volume fader fully down some sound still bleeds through. Any ideas at the extent of repair required? New fader, just some misalignment to rectify? Help from anyone would be appreciated. Thank you.
While I'd love to tear down more controllers, I only own a DDJ-1000 and DDJ-400, I can't justify the cost of buying full price controllers purely to make teardown videos of them.
Don't worry, no damage was done, it's back together and fully functional, if anything this video could serve as instructions to help people fix their controllers 😉
Really comes down to the software you prefer, the DDJ-400 is aimed towards Rekordbox DJ, the SB3 is geared towards Serato. At least for me the benefit of the DDJ-400 is that it includes a full copy of Rekordbox DJ whereas the SB3 only includes Serato Lite which is somewhat limited in terms of features.
I like how they decided to use a single sided board and then throw a shitton of links on it. Clearly a management-decision. Let's give them more money than the poor guy layouting this board great with what was given.
I was trying to work out how the connector worked, it was a type of connector I'd never seen before so was a bit confused trying to work it out live on camera. I don't rehearse these teardowns so you'll see me trying to work things out live.

Might do them soon since I'm not spending nearly as much with the current lockdown but I also need to budget for other things like replacing the expiring smoke detection.
Does some body knows where can I buy the mother borad of ddj400
Hi, what screwdrivers are required to remove the screw?
They're all Philips screws, from memory they're PH2 but don't quote me on that!
The board actually can just play a bunch of music you search up as your mixing on the board on soundcloud
Sir Mera ddj RB controller ka headphones jeck aux not working
Nice video!
Can you please do the tear down of Pioneer DJ DDJ-FLX6
While I'd love to do more teardowns of stuff like this, I only have access to equipment that I own myself and these teardowns sadly don't generate enough revenue to justify the cost of buying equipment to teardown.
@@camerongray1515 It would be interesting as they appear to share the same pitch adj component but the FLX6 has a higher pitch accuracy in Rekordbox than the 400. The FLX6 is able to get every increment but, the 400 is just shy about 0.02 BPM out. Still accurate, just not as accurate. I have electronics education /knowledge & service my own Pioneer Mixers & CDJs but, I won't look & ruin the warranty on them until I need to 🤣
Can you please do one for the DDJ 1000?
I'd love to but unfortunately don't own a DDJ-1000!
awesome, gracias
Sometimes the jog wheel just doesn't respond unless i tape on the center of it
Me too , having that problem. How did you fix it ?
My DDJ 400 recently developed a fault: When I put my left deck's volume fader fully down some sound still bleeds through. Any ideas at the extent of repair required? New fader, just some misalignment to rectify? Help from anyone would be appreciated. Thank you.
Hey man I've got the same problem, did you figure out a solution?
You need to replace the channel fader
can you do the ddj rev 1 next?
While I'd love to tear down more controllers, I only own a DDJ-1000 and DDJ-400, I can't justify the cost of buying full price controllers purely to make teardown videos of them.
Don’t ever play the “board” drinking-game!
Edit: interesting stuff. This keeps me from opening it myself. Thanks
It more than likely the sound card or if my memory is working I am sure there FGP processors there cool to hack around with if if is
Getting these crossfaders off is a nightmare
Ima use this for tuorchering dj’s😁
Don't worry, no damage was done, it's back together and fully functional, if anything this video could serve as instructions to help people fix their controllers 😉
2:18 crossfader cap
please do for ddj sx2 controller
Unfortunately I don't own a DDJ-SX2 and don't have the budget to get one just for a teardown.
Saludos
Sbonge 🙌🏾
DDJ-400 OR DDJ-SB3?
Really comes down to the software you prefer, the DDJ-400 is aimed towards Rekordbox DJ, the SB3 is geared towards Serato. At least for me the benefit of the DDJ-400 is that it includes a full copy of Rekordbox DJ whereas the SB3 only includes Serato Lite which is somewhat limited in terms of features.
@@camerongray1515 Thank you very much. BTW which controller do you use?
Genial! 💪🏻
If you Google Fcc number you get images on the fcc website
Now do Hercules Inpulse 500 ;p
I like how they decided to use a single sided board and then throw a shitton of links on it. Clearly a management-decision. Let's give them more money than the poor guy layouting this board great with what was given.
My shift key is jammed and I have a set in 7 hours 💀
Ничего не понятно,но очень интересно)
play cue parchase for me sir
10:00 ?????
I was trying to work out how the connector worked, it was a type of connector I'd never seen before so was a bit confused trying to work it out live on camera. I don't rehearse these teardowns so you'll see me trying to work things out live.
