My usb port just got damaged today, its wobbly but not all the way broken. I have no experience soldering, do you think I am able to fix it myself? I will come back to let you know how I do.
I highly suggest you practice a bit your soldering skill a bit before. Soldering the 4 pins is not that much hard but the process of unsoldering can be. Just be really careful and gentle during the process and it should be fine. Good luck!
So I got a desoldering pump and a new connector and I managed to get the old one out and the new one in. I'm not great at soldering and it certainly wasn't the cleanest job, but I managed to get it in without any of the contacts touching. When I plug it into my laptop it powers on but the backlight is very dim. If I use a power adapter the lights are bright and everything appears to work as it should, but either way it won't recognize it as a usb device or transmit midi data. I'm wondering if perhaps I somehow fried that part of the circuit board when taking out the old part? Let me know if you have any ideas. Thanks!
Double check the spec but this should do: www.digikey.ca/en/products/detail/te-connectivity-amp-connectors/292304-1/773785?USB%2C%20DVI%2C%20HDMI%20Connectors&Shopping_Product_Connectors%2C%20Interconnects&productid=773785&gclid=CjwKCAiArNOeBhAHEiwAze_nKMMk8NHJNFHLKLzq2YiXanwx_vOqzl4J_KqauZP0PfmzrQ0340VKCRoCZKkQAvD_BwE
Thanks a lot for the how to! Mine broke too! Akai MPK 249. Where did you get your new USB port from? Is it a standard part or an AKAI part? This happens to many people. If this is an AKAI 'professional equipment what's the normal stuff like? Badly made device! NEVER BUYING AKAI AGAIN!

Is there a wattage requirement for the soldering iron? I got a 30w but the solder on the board doesn’t liquify at all when I hold the tip against it. This is my first time soldering though, so I’m probably doing something wrong.
You would find it easier with something like a Weller soldering station. 60-85W will do the job. Adjustable temp are really useful. I usually set it around 750-800f depending on the job.
Great video. Thank you! The Presets Screen / Display does not light up. Looks dead. The pads light up but the screen does not. Does anyone know what the problem is? Thanks in advance.
@@ThePhilStudio Thanks! I will keep that in mind. There is no info online regarding this issue. Would be comfortable changing the screen myself if that is the issue. Don't even know if I can find a replacement. Would still love to hear from anyone who has this same issue.
@@ThePhilStudio There is no screw that holds it together. I thought you could be able to just pull the knob off but it doesn't work like that. It seems like it's glued.
@@Elliothpacheco maybe there is a short circuit or one was caused by the damaged USB, it can cause a power switcher to fail. If you plug the unit with a power supply, does it power up?
This is called ''Contact 2000'' which is a contact cleaner for electronic. If you wants to clean the board after a soldering job, the best would be to use some ''Flux Remover'' or the ''Contact Cleaner''.
@@brandonhamilton370 personnaly I have never used WD40 for electronic. It's more a product for mechanic stuff. I guess you would have to try it. Be really careful because I'm not sure if it conductive and also avoid contact with plastic casing or parts. Let me know if you try it and get good result.
My USB port was damaged from the jump then finally gave out..my dad tried to fix it and made it worse lol. I wish there were stores that repaired them. I don’t even think guitar center actually repairs stuff.
@@ThePhilStudio I ended up buying midi chords to power it and it turned on but was super glitchy and I coukdent even make anything..idk if it’s the chords or the keyboard. I still wanna get the USB port fixed tho.
I do value repair. But not at every cost. Sometime the cost of a replacement board is more expensive than the device itself. If this includes shipping a piece from across the globe, I will think twice as well before doing so.
You should not consider yourself as a tech... The way I see you unsoldering the board is nothing more than hobbiest level... Real professionals are doing this differently...
Today is a great day!
Thank you once again.

This could be one of the capacitor on the side of the usb connector.
Mine also is not recognizing anymore, did you ever figure it out?
Can you hook us up with a link to the usb connector?

The connector is a USB chassis connector and is really common in most machine. :)
@@ThePhilStudio Cheers! Yes found one thank you. :)
Is there a possibility for a link that could show me a good usb connector?

where’d you get the new usb, i have the same issue just don’t know what usb connector to get
nvm i found it in ur comments, hopefully i dont have trouble desoldering!!
@@peb9840 That's great! Watch out, desoldering is a bit harder than I thought since the four pads are fragile and the ground pads need a lots of heat.
Great video. Thank you! The Presets Screen / Display does not light up. Looks dead. The pads light up but the screen does not. Does anyone know what the problem is? Thanks in advance.
@@mannshambles7006 it could be the screen itself. If you're comfortable opening it, check the ribon cable or connector that goes to the lcd board.
@@ThePhilStudio Thanks! I will keep that in mind. There is no info online regarding this issue. Would be comfortable changing the screen myself if that is the issue. Don't even know if I can find a replacement. Would still love to hear from anyone who has this same issue.
Thank you for helping with this video I have same problem with same midi keyboard. I would liket to know if that was enough to fix the problem
Yes it did fix the issue.
Would it be possible to ship you my USB port board and pay you for a repair of this exact same procedure? Thank you for your time.
Sure, contact me via my e-mail, we will see the cost of shipping and repair depending on where you live.
Any experience with replacing the USB connector on an akai mini 2?
Haven't had the chance yet, unfortunately.
Do I need a desoldering pump to do this?
A desoldering pump will definitly help. You may do it with desoldering copper thread if you're good with it.
Do you know how to remove the knob that is next to the display? I cant seem to remove it.
Carefully pry with a flat headed screw driver and make sure there is no set screw or that it isn't glued since you could damage the circuit.
@@ThePhilStudio There is no screw that holds it together. I thought you could be able to just pull the knob off but it doesn't work like that. It seems like it's glued.
great video thx
It's a pleasure! I'm glade you liked it.
SIR,
WHAT IS THE PART NUMBER OF THE REPLACEMENT PORT ?
UJ2-BH-BL1-TH
brother exactly the same thing happened to me with my akai but now my mac and my laptop do not recognize the controller can you help me with that?
Have you replace the USB connector yet?
yes bro and now the pc does not recognize it and the pads do not turn on
@@Elliothpacheco maybe there is a short circuit or one was caused by the damaged USB, it can cause a power switcher to fail. If you plug the unit with a power supply, does it power up?
Did you ever figure this out? Having the same problem
@@MuteProtest If the USB input was completely replaced and is working at 100% until now.
how do you put the ribbons back? i really hope i didn't just break my keyboard 😰
never mind i just shoved it back in and everythings working perfectly. thanks for the video 😅
Great! I'm glad you could find the solution, thanks for your patience, I couldn't answer quicker.
Small tab that lifts up so they can be placed back in just right.
Just take your time pimp.
You will get it right
They sell the ribbons the same place they sell the USB port and they dont cost much.
The port does though.FYI EVERYONE.

@@ThePhilStudio I ended up buying midi chords to power it and it turned on but was super glitchy and I coukdent even make anything..idk if it’s the chords or the keyboard. I still wanna get the USB port fixed tho.
@@DuckGoddies i feel you! Do you know any repair shop or electronic tech in your area?
Those in your homeland value your items
I do value repair. But not at every cost. Sometime the cost of a replacement board is more expensive than the device itself. If this includes shipping a piece from across the globe, I will think twice as well before doing so.
It's a midi controller only.
Thanks for the clarification. I don't really know that device, I was just there to repair it and ensure it would works in the end. ;)

He still got it done and taught me how to fix mine so I’d consider him worthy of repairs knowing nothing about the keyboard
