[HW: Repair] - Numark N4 disassembly + Play/Cue repair

As title says, i got this thing for a repair and decided to record a video since i did not do that in a while...
yeah, it's actually quite easy to open this controller and replace components (most of them).
If you have any questions regarding this process, don't hesitate to ask.

Thank you 🙌🙌 just fixed my play pause and my cue buttons 👏

Redy drv602?

Any suggestions for damaged Master volume? Someone spilled a beer and some went directly on the master volume and of course the music volume kept getting lower and lower for 20 seconds until the sound vanished. Knocked out the headphone sound as well. Everything else is still working with Serato except for sound. I've never dealt with liquid damage repairs. I've replaced several phone screens but none with liquid damage. If liquid damage is not fixable I guess I'll have to trash my Numark N4. I'm taking it apart now.

[@MTS_IT]

Just buy the replacement on ebay and tesolder it. (It’s actually cheap)

[@ryannrjohnson]

@@MTS_IT I purchased a new Numark NS6 II and ordered a can of Deoxit spray for my Numark N4. The spray fixed all the sound on the N4 and it works great again, however I like the new NS6 II controller features much better. But unfortunately the music starts to sound erratic and slow down and then it disconnects from Serato several times while I'm doing parties. I've reached out to American Musical and Numark but Numark hasn't responded so I guess I'll have to reach out to my bank to see if they can intervene in the warranty for the new controller that's failing.

How do I deal with crackling sound when turning the master volume knob please? Sometimes it leaves only one side (left or right channel) with sound.

[@MTS_IT]

hi, this is the general idea: kzbin.info/www/bejne/bX3Ok5J3l8Z_hac i hope it helps :D

[@wavephaze460]

I hope you have an answer for me... what are the eq/effect knobs called. Like the play/cue one you replaced

[@MTS_IT]

Wave Phaze hi, ebay for : numark n4 rotary pot :)

[@benm2176]

I opened my NV to attempt to fix the sliders but now none of my buttons work. Any idea what the problem could be? I think I put every connection back in correctly

[@MTS_IT]

maybe it's constantly pressed. Sometimes plastic ends up pushing button

[@antonsempron3356]

What are the potentiometers in Numark N4? Marking?

[@MTS_IT]

i don't have it anymore :/ sorry

[@djleftyloca]

@@MTS_IT do you know where i can get a power cord from ? this would be really helpful.

[@RSCarlH]

[@driptamine1162]

Ordering new play button for my numark n4, what size play button do you recommend? From 6x6x5mm - to 6x6x13mm?

[@michaejsmont3167]

Which one were you ordered ?

[@mrrafsk]

I also want to know what one fit pls?

[@spencerwilkerson6458]

any idea on how to replace fuses? i have a Numark NV that suddenly popped and wont produce sound anymore from speaker or headphone port

[@MTS_IT]

uff... are you sure that it's a fuse? If i had it with me i would probably figure something out, however i cannot help you since i don't have it in front of me :(

[@spencerwilkerson6458]

@@MTS_IT getting ahold of a company I learned that it may be a transformer, but thanks for your time anyways!

[@MTS_IT]

Cool! To be honest that’s super rare, however i guess that it’s possible :)

[@spencerwilkerson6458]

@@MTS_IT ill make sure to keep you updated! pretty interesting learning opportunity for someone who doesn't know the electrical side of a mixing controller

[@diegorodriguezh]

I have a problem similar to that but with volume sliders that do not respond correctly

[@MTS_IT]

Diego Rodríguez i would say that it’s a faulty potentiometer

[@modernrandomstudio4072]

what buton you use for the play/cue, i have the same problem, sorry for my bad english

[@MTS_IT]

Hi, you can use: www.ebay.com/itm/100pcs-4-Pin-Momentary-Tactile-Push-Button-Switch-SPST-Miniature-Micro-Small-PCB-/141986870574?var=&hash=item210f13b52e (not affiliated in any way) they are quite cheap. Or you can buy "the original" for about 10$ from ebay, however, in my experience these are the same switches with the same quality.

[@modernrandomstudio4072]

thank you mate you saved my life, have a nice day

[@driptamine1162]

@@MTS_IT Hey with the link you posted here the buttons have a certain size to them when you order, what size button did you use for the numark n4?

[@MTS_IT]

@@driptamine1162 hi, i THINK and keyword here is THINK that they are 6x6x6 (90% sure) because i have shitload of micro-switches of every size, also, you'll need ones with 2 pins (NOT WITH 4)
