Akai MPK249 Repair

A quick video on how I repaired that Akai MPK249. Basically, the USB connector was destroyed. I replaced it and now works like a charm.

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!

[@ThePhilStudio]

This could be one of the capacitor on the side of the usb connector.

[@Pennywaffer]

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.

[@ThePhilStudio]

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.

[@TheEason]

Any experience with replacing the USB connector on an akai mini 2?

[@ThePhilStudio]

Haven't had the chance yet, unfortunately.

[@jackmerucci2398]

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.

[@ThePhilStudio]

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!

[@itsstatic2454]

Mine too lol

[@pabloarmasb]

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

[@ThePhilStudio]

Yes it did fix the issue.

[@LarrickOwnz]

Do you know how to remove the knob that is next to the display? I cant seem to remove it.

[@ThePhilStudio]

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.

[@LarrickOwnz]

@@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.

[@smilebeatz5103]

how do you put the ribbons back? i really hope i didn't just break my keyboard 😰

[@smilebeatz5103]

never mind i just shoved it back in and everythings working perfectly. thanks for the video 😅

[@ThePhilStudio]

Great! I'm glad you could find the solution, thanks for your patience, I couldn't answer quicker.

[@SavBeatz97]

Is there a possibility for a link that could show me a good usb connector?

[@ThePhilStudio]

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

[@SavBeatz97]

@@ThePhilStudio Thank you so much. 🙏🏽

[@mobur1234]

Do I need a desoldering pump to do this?

[@ThePhilStudio]

A desoldering pump will definitly help. You may do it with desoldering copper thread if you're good with it.

[@peb9840]

where’d you get the new usb, i have the same issue just don’t know what usb connector to get

[@peb9840]

nvm i found it in ur comments, hopefully i dont have trouble desoldering!!

[@ThePhilStudio]

@@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.

[@supnorway]

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!

[@ThePhilStudio]

The connector is a USB chassis connector and is really common in most machine. :)

[@supnorway]

@@ThePhilStudio Cheers! Yes found one thank you. :)

[@brandonhamilton370]

What is the liquid that you sprayed on called?

[@ThePhilStudio]

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]

@@ThePhilStudio Would WD40 work as well or no?

[@ThePhilStudio]

@@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.

[@joshuachinchilla927]

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.

[@ThePhilStudio]

Sure, contact me via my e-mail, we will see the cost of shipping and repair depending on where you live.

[@Elliothpacheco]

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?

[@ThePhilStudio]

Have you replace the USB connector yet?

[@Elliothpacheco]

yes bro and now the pc does not recognize it and the pads do not turn on

[@ThePhilStudio]

@@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?

[@user-qv5fk2nx2p]

SIR, WHAT IS THE PART NUMBER OF THE REPLACEMENT PORT ?

[@ThePhilStudio]

UJ2-BH-BL1-TH

[@DuckGoddies]

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]

Where are you from?

[@DuckGoddies]

@@ThePhilStudio Albany Ny

[@DuckGoddies]

@@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.

[@ThePhilStudio]

@@DuckGoddies i feel you! Do you know any repair shop or electronic tech in your area?

[@lessstrainmovers779]

It's a midi controller only.

[@ThePhilStudio]

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. ;)

[@mediacousticsmultimedia7359]

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...

[@SoberrHits]

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
