How To Repair A Faulty Midi Keyboard USB B ( 2.0 ) Connector

[@skunker505]

I had this exact problem and replacing the USB fixed it! For anyone watching, be mindful of the little pads that you solder onto (the rings around the holes where the pins go through). On mine they came right off when I was removing the old USB connector. I was able to scratch off some of the PCB material to expose the copper underneath and make a little solder bridge from the pin to the copper. It was barely making contact but it works!

[@hotpotatapie]

I just did the same thing to fix an AKAI keyboard. He seemed to have no damage to the PCB traces (donut shape pads) when he unsoldered. I guess I heated them too much, but 2 of mine came off/got destroyed, so like you, I made a little copper wire jumper and soldered that.

[@timmacdonald8141]

Thanks you two- im about to tackle my Steinberg audio card- I got the ur-rt2 so it’s scary

[@FelipeLeiter]

@@hotpotatapie bro i have same problem, where did you soldered the copper wire, in wich of the 4 little holes ?

[@shizit94]

you just saved me $200 with that little detail: Don't let the connections touch!

[@89sammyguitar]

Wtf I just searched for "usb b repair" and that was the first video and this is precisely my problem with exactly the same MIDI piano 😃

@@willemschonfeldt6227 Interesting! Sign me up.

[@timpullen4941]

when you solderer a plug like that you should solder the big points first because this anchors the plug and when you solder the data pins you will not be putting pressure / force on the solder points on the PCB. ( I am an engineer with a keyboard company )

[@musicsterrible]

Had the exact same problem with my axiom 49. Thanks for the video! This repaired it. I had to make sure the solder on the 4 pins didn't touch each other. It wouldn't work at first when the solder was connecting/touching the other pins. Thanks again.

[@King45Moses]

My man does everything!!! I’m in the process of moving and rebuilding my studio and had this issue where is was saying device can’t be identified or whatever, and look who has a tutorial on it! 😂 I’ve been wanting to learn soldering anyways so this is my opportunity, took my keyboard apart and it looks like the usb was pushed in too hard and broke the connection, waiting on my parts to come in the mail!

[@OmoiSenpai]

Best bet I do everything :P Little bit of this and that here and there! The latest thing that is out from the norm was to build a soundproof isolation booth: kzbin.info/www/bejne/mZnZp4uugax2d7s Just, make sure not to work too hot, and don't burn the board, otherwise, you're pretty much screwed! 0,0'' No stress though! :3

haha, I was looking for a way to tighten this usb type with pliers or something and what I got was someone violating all the rules of soldering. I dont do it much myself, but I liked watching channels like Voultar on yt for some hot tips. It's pretty interesting and he fixes up old Nintendos and things. Keep the dream alive brother

[@OmoiSenpai]

Super late on the response, but I hope it worked out for ya! =] Unfortunately, I've did the replacement again, but this time. I think I burned out the chip board T_T I had the heat on too high I'm guessing.

[@christopherroa9781]

Great video! Gotta do this cause I dropped my launckey. Quick note but make sure you do a clean solder with 30/70 lead tin. Looks like the right side is a dead joint which will fail after a year or so. Cheers!

[@OmoiSenpai]

Thanks! If I had Flux, it would have made the process 1000% better and I would have avoided the cold joints. I did run back it in the video, but I heavily trimmed it down to help with the retention after publishing. Good catch! ^_^

[@DynamicRockers]

Heat the pads first and apply solder on it, or you'll get cold joints. Thanks for the video

[@OmoiSenpai]

No problem! And yeah. I definitely did not do a lot of things when it came to the soldering, especially not having flux xP

[@barsyholland9317]

I have the exact board! This video is very helpful. Thank you!

[@ceejaysoul4811]

This seems to be what’s wrong with my Oxygen 25, i have fixed the problem with the power being stable but still struggling to get it to register to my Laptop & DAW. Think a replacement female port might be the best option. This was incredibly helpful!

[@Hytherious]

guys, gotta ask because i've been looking for a solution but i just can't figure it out. took my midi controller to a solderer, he soldered the usb type B connector and now my midi plug and play controller lights up but Windows doesn't recognize it, it doesnt even make a notification sound when connecting it, seems like my laptop isn't receiving any data from the midi and i just cant figure out a solution!

What if you solder the usb cable direct to the motherboard. how would you do it? the colour coding to the motherboard

So how did u solved the problem whem the pc wasn't recognizing the keyboard? I mean did u soldered again or?.. pretty confused about that. I have the same problem on a 49 keys oxygen by m-audio and just ordered all the equip for the job.

[@OmoiSenpai]

The PC did not recognize it after I installed the new USB Piece, because there was a bridge of solder between 2 of the points and I did not notice it the first time around. I had to remove the bridge by re flowing the solder and removing that link. Hope that helps, and good luck!

[@motheroats]

I have a gen 1 axiom 49, I plug the usb in and the power works perfectly fine to it but my Mac won’t recognize it and Logic Pro X, do you think the USB pot itself has an issue even if it powers on?

[@TROMO]

motheroats have the same problem :( did you find any solution??

[@dredayonnabeat]

TROMO the Usb connection has to be strong...No wiggling or quick disconnects.

[@Kendonezia]

I had same problem with my 1st generation 25. I bought a midi to USB cable and had to find a power adapter...boom

[@theorncampbell4432]

You have to find the 'Axiom Pro.bundle' file online somewhere. Download it and put it in the Logic Pro's MIDI device plugin folder. Once you've done that you, HYPER CONTROL functions will work. The 1st Gen Axioms won't work unless you do this. Cheers.

If it hasn't already been mentioned, use blu-tac to hold components in place. Or masking tap. They don't leave much of a residue. Also you should start soldering the larger pins first before the electric signal pins.

maybe very stupid question, but does the usb b female connector have to be new? i have an old printer that i don't use, and am wondering if i can take the female connector from it to add to my keyboard? but i never soldered anything btw, so maybe, once it's been used (and soldered) it cannot be re-used?

Hey I got a Akai Mpk 25 and plays notes by itself is it the USB port? When I move the cable it calms down

[@rstark89]

Before you do all this soldering you can try spraying a little Deoxit in there, it's like WD40 for electronics and helps maintain the connection. Just recently discovered it myself and it's had several uses already. Worked to fix my USB port which only worked when it was held to one side.

[@susu-mi7kx]

I'm going to do this but is it possible to just use the midi in and out ports?

[@xenosoul1363]

only if you can get power to it...for instance a wallwart and midi would work. I had the exact keys hes working on, i gave mine away to my nephew, but i bought him a midi to usb connector and a wall wart (plug) and it works fine. Im now having the same problem with my vi49, this clears up how to fix it, but i might just go the midi powerplug route so i dont damage it. who knows maybe ill grow some nuts

[@shinyless]

Thanks Homie ^_^ DIY is the way to go!

[@Mid0z1]

do you have any idea where can i get the "board" that carries the usb port on it ?

Sorry, I don't know of any.

[@MrKrampyHands]

Hmmm i got a busted one if these days on my sim racing pedals its the one you use to connect to the pc its important i got it working in a ghetto sort of way but the back cap on the port stays loose i had to shim the top of the port so when the pedal if assembled it puts pressure on the port so things actually make contact and stay put i gotta have a new one soldered in this one sends power and information so i gotta find exactly what one i need to make a proper fix

i just shoved like 2 joint filter tips to stabilize the usb port and so far it works and stopped the disconnection... ill update if my house burn down because of it 😂

[@nikhilesstudio2449]

Thanks brother

[@chrisco2323]

First, thx for this vid, watched twice. My prob though: new USB female too tight. cable insert actually makes a nice satisfying click, whereas old one seemed only very slightly loose. I've never soldered before. This is an Akai MPK88. I've tried 3 cables (male USB-C) all same. It takes some pressure going in (already too much) then that nice click. It takes a lot of pressure to unplug--way too much. So even if I was a master solderer, this would break instantly as soon as I solder new one in. Any advice please and thanks?

[@mikebello_music]

Hello, some days ago, someone flatted my USB cable and broke the connection, I did everything I saw in your video and it worked, the controller turns on and everything works fine on it, but when I appreciate the macbook it does not detect it, what do I do?

[@OmoiSenpai]

Hey! Did the keyboard used to work with the Macbook before this happened? Did you replace the USB Cable wire as well? I don't own an apple computer, so I don't have much experience with it, but if you never connected the keyboard to a mac before, you may have to search and install drivers for it.

[@mikebello_music]

@@OmoiSenpai If, before this happened it worked correctly, I did tests with several cables, and the cables are fine since they work with others of my controllers, and other controllers work just connect them, I have never needed to install drivers or anything, I am about to try if through the MIDI out connection it works and if it also works with another laptop

I did this repair on my own, it was tough no lie. Do your best when soldering to keep the pins soldered seperately, solder at the proper temperature, and make sure things are nice and clean for a good connection. I bought a 6 pack of USB connectors on ebay for like 8 bucks. So yeah.

[@JitendraWagh73179]

There is another tip on this, I too have the same keyboard with the same problem. Just Use a paper tape or medical tape and wrap it over the Usb Mal B port / the cable connecting the keyboard. Use 1/2 rounds just to make a snug fit, and it works perfect.

[@vicksindamix]

So you said you bassically wrapped your USB b cable in paper tape and it worked out?

hello, i have the same problem, its first time soldering for me, i thought i did a good job, but the keyboard wont start at all. Figured i took the copper pads off with the usb... what is the solution, how do you replace it?

[@OmoiSenpai]

Ouch. It sounds like, you burnt the whole board's pad? I don't really know where to go from there. I'm not an expert on that topic. =/ The only thing I can think of kind of related to that, was something like Nintendo Cartridges. They would scrape off part of the circuit board that had a trace of the copper circuit, and then hard wired it back to the circuit board to create the connection using a small wire. Like I said though, don't take just my word for it! Hopefully you can get that figured out!

Hey there! I would assume that all USB Type B Female Ports are the same. I did not look into specifics when I bought mines ( other than making sure that it was a USB Type B Female port, and not some Type C or micro lol ) Have you looked at the soldering on the old USB port already? If the device powers on when the USB wire is at a tilt, maybe the solder points needs to be re-flowed in order to gain back it's connection and hold onto it.

I can't really give you an answer since I don't know what keyboard you're using, what random numbers are showing etc. If the random things are like "CC 14" or something, that's part of the keyboard controller. Read up it's manual to fully understand what is going on with it. And see to make sure that you installed the right driver for it. If it worked before, and then you tried to re-solder the USB port back, chances could be that the contacts were bridged together, or not fully contacted.
