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.

I'm genuienly impressed by how knowledgeable you are about the electronics.

Fascinating breakdown. Thanks for going through the trouble of tearing down the controller.

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!😊

this is great! thx for making this. I think this is the only ddj 400 teardown on KZfaq

Thanks for the video, following it, I was able to repair the tempo from my ddj-400!! many thanks!!

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 😊

7:00 the microphone is not captured by the computer on the DDJ400, straight through to output. Very interesting video, thanks for posting.

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.

Nice teardown. I've taken the SB2 apart before, looks similar, just different layout.

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.

First video I've seen that shows how to remove these fader knobs properly!

Man i was about to chuck my ddj 400 out but thanks to your video I realized there was water damage in one of the faders so I got to order replacement!

Thanks! Got a dead cue switch on one channel on a DDJ-400 and this video was a lifesaver, now I know it should be easy to get fixed :)

man thanks please do more like this you are saving jobs here

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...

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

Thank you. Successfully cleaned up my sticky CUE/PLAY buttons after spilling some cider.

Is it possible to get a comprehensive parts list? I'm working on my own custom controller and would like to know what components are COTS.

Thanks for the tear down. Now I can fix my cue button

thanks for posting this video, i found that i can repair a defective cue button!

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.

Thanks, just fixed my volume fader following this - just a little dust!

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

I have a jog weel problem on my SB3 Pioneer i get a delay sometimes when trying to scratch or even pull back a tune using the jog weel what can i do

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!

Would you say the light readers for the jog wheels could break or is that very improbable?

My friends mixer got water damage from the front probably. What should i do now or check first?

thank you man i fixed my ddj-400

Teria como tirar os faders e trocar por crossfaders??? Funcionaria normalmente, ou o tamanho deles são diferentes??

will a replacement 20861 for the 2896 flat ribbons be okay or is the voltage difference too high?

Great video, Cameron! Any advice - I spilled liquid (beer) into the crossfader, seems to be working fine, is there anything I should do?

thank you for exploring !

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!

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?

How did you remove the ribbon cables?! I can't seem to get mine out

My USB port is bad. Is it replaceable or will I have to replace the entire interface. If so, where could I possibly order the interface.

What could be a common reason for the track selection buttons don't work at all, given they're on a different board?

Would it be possible to change the cross fader out to a magvel fader pro?

Hi can you replace the headphone interface output ?

Hello. Bro some buttons on my dj Controller is not working. Can you tell how to fix them without removing back.

Please, links on amazon of good brands and models in pushbuttons for that controller Thank you

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...

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!

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 ?

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?

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.....

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

HOLA..EXCELENTE VIDEO.puedes decirnos el valor de los potenciometros de canal uno y dos..??

I really enjoy your channel

hola quiero cambiar el fader izquierdo .......como lo hago ?

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‽

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.

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?

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

you save my ass! I was afraid of open my controller until I saw your video! THANK YOU SO FKN MUCH!

Great video thanks!

Does some body knows where can I buy the mother borad of ddj400

Me salvaste la vida. Saludos desde Bolivia.🇧🇴

Nice video!

are the two platter things not digital encoder controllers to can swing the audio track back and fourth, Most of the unit uses DSP processing

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?

CAN U REPLACE WITH 🤔 RGB LEDS ON MY SB3

I would imagine you could use this guide to teardown a DDJ 200? My second channel faders not working. Hoping its just sticky or dusty but if not can buy a replacement off eBay for £6.

how can I remove the brows knob?

I'm watching this to gauge how big of a project replacing the broken USB port on my DDJ 400 would be lol

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.

Are those rotary pots actual pots or (absolute position) encoders? Pots usually only have 3 connections, those seem to have 4.

Sir Mera ddj RB controller ka headphones jeck aux not working

Hi, what screwdrivers are required to remove the screw?

awesome, gracias

Sometimes the jog wheel just doesn't respond unless i tape on the center of it

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?

Please help me, i got an issue with the left volume fader and CFX knob, some kind of malfuncion, not working properly anymore =(

The board actually can just play a bunch of music you search up as your mixing on the board on soundcloud

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) 😂

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

Cameron have you replaced your sockets to metal ones yet?

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.

Ima use this for tuorchering dj’s😁

Can you please do one for the DDJ 1000?

Can you please do the tear down of Pioneer DJ DDJ-FLX6

can you do the ddj rev 1 next?

2:18 crossfader cap

Genial! 💪🏻

If you Google Fcc number you get images on the fcc website

Now do Hercules Inpulse 500 ;p

please do for ddj sx2 controller

Sbonge 🙌🏾

Don’t ever play the “board” drinking-game! Edit: interesting stuff. This keeps me from opening it myself. Thanks

DDJ-400 OR DDJ-SB3?

Getting these crossfaders off is a nightmare

play cue parchase for me sir

Saludos

Ничего не понятно,но очень интересно)

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 💀
