How to Fix a Bad DC Power Jack

Fix a faulty Power Jack (intermittent connection) by bypassing the broken one (Korg X-50 example) and substituting a new panel mount one.

[@jimbob4217]

Thanks, this is so helpful. My very first soldering job and I've fixed my X50 with your guidance..and added a jack that its easy to find adaptors for.

@@eddieloius4592 All that matters is that the plug and the jack match- ...so if you solder the "+" connection from the circuit board to the tip or pin of the jack, the plug needs to match the polarity and be supplying "+" voltage. (thats how mine is wired) Hope that makes sense and good luck!

Good luck with the repair. I've had 2 Micro X's through the years and they are great little synths. Amazing sounds for the price!

[@travisreinert]

This was very helpful. I put my power jack in another location that worked out well and did not have any danger of shorting to the shielding foil. Also the shape of the jack nut fit just inside the walls in the pocket and prevented it from turning. Just to the left of the molded in strain relief horse shoe in the very corner on the back. Worked perfectly. Also out the side under the handle is a great place with tons of room and the power cable can be wrapped around the handle for strain relief. Wish I could post pictures in this comment.... I also designed and 3d printed a closeout plate to cover the unused rectangular hole, just hot glued it in. A much more robust power input system now, plus the adapters with the new standard plug are much easier and cheaper to find. I had to fix both my flaky X50s and I'm sure that I will need to do this to my other 3. I am a huge fan of this little board. Its the best for live performance.😃😃

That instrument is a multimeter and you can get inexpensive ones like this: www.harborfreight.com/7-Function-Digital-Multimeter-63759.html I'm not sure of any other way to test and be sure that you have the polarity right except by trial and error.

[@pedalboat90210]

Hi, like the video, I have a Zoom B9.1ut guitar pedal with a wobbly jack that cuts out intermittently and often if touched or moved slightly. I have a replacement barrel jack and was going to solder it to the board but it seems impossible to desolder the old one so I may do this instead... what wire would I use? I believe it is 12V and 3 Amp input. Thanks

[@LearnLizard]

I'd use 22 or 24AWG stranded copper wire. Yes- It's really hard to remove/replace those mounted jacks without damaging something- thats why I decided to bypass the whole jack. Good luck getting the pedal working. Intermittent power is no good!

[@jokerswildmusic4882]

Question, when buying a replacement power jack to mount on do you have to find one specific to certain specifications of what your keyboard requires?

[@LearnLizard]

You can basically buy and use any male/female jack/plug combination. As long as the jack can be mounted in the keyboard and wired to the circuit board, and the matching plug can be soldered to the external power supply leads, you should be golden.

[@pear_bear]

really cool video! :)

[@LearnLizard]

Thanks for that! (appreciate you watching)

[@samsimgeo]

This is awesome! Would this Female DC jack fit all keyboards? Like the mini kids casio boards as well? Thanks

[@LearnLizard]

Thats a good question. Some keyboards have very tight spaces between their circuit boards and outer cases so could be a challange. Probably have to crack it open to see how much space you have inside to work with. Appreciate you watching!

[@ktownc936]

If I were to upgrade the internals of my microscopes led to handle 12 volts would the original 5 volt female jack work? Or are jack inputs interchangeable so as long as the polarity (center negative) is the same.

[@LearnLizard]

I believe it should. Most low voltage power jacks will handle at least 12V. Thanks for watching.

[@mylocast]

Mr LearnLizard, great idea on bypassing the failed "jack port" on the original power circuit board. At time stamp 1:28 you are IDing the polarity of the current. Do you know what the 3rd post for on the failed port does or is for?. IF you look closely you see three solder points, 1 is Positive, 1 is negative, and the 3rd? At first I thought maybe it was a ground, but I'm thinking that wrong, since there is no ground on the adapter power supply. I'm not an electronics guy, but I'm looking at doing something similar to what you did here, however, I wondering what the other post on the jack port does. Any ideas?!?

[@LearnLizard]

I think that third post is just for holding the jack securely to the PC board (so it has a 3 point "tripod" support) Thanks for watching this one!

[@adrianagarcia1175]

Thank for the video but as I'm not a techinician, I've not the equipments to fix it. But I've bought a new DC power connector but the pin is bigest than the original one. Is possible to adapt it or certainly is the card ? Thank you.

[@LearnLizard]

I've seen adapters for sale that change the jack from one size to another. You also might consider buying a universal power adapter that comes with a variety of jack sizes. Other than that you could buy a soldering iron and learn to solder. Its really pretty easy. Appreciate you watching!

[@nermindlamadema3332]

Thanks for sharing, I have same problem on LG TV DC power jack, I wonder how did you find right jack for that power supply?

[@LearnLizard]

Connectors are usually named by their barrel size but it can be hard to get the right internal pin size. Back when there used to be Radio Shacks I would go in and match the jacks in a store. Now I try to research it online and do an Amazon return if I an wrong (which has been more than once)

[@marcomizzoni8323]

So is this better then replacing the original dc and using the Korg part? Are you using the original power cable too? I actually have the micro X which is pretty much the same keyboard but smaller footprint. How come you chose to go this route over direct factory replacement. Awesome video!!! Thanks

[@LearnLizard]

Hi Marco- I had an OEM power adapter with the same specs as as the original x-50 and used a female socket to match it. It was easier than removing the surface mounted one that broke (and I think more "bomb proof") I also have a micro X but so far that cable is behaving :) Thanks for watching!

[@raindogred]

mine took a fall years ago, and has net been used since. I plugged it in today, it's dead, but if I wiggle the jack it powers on and off like yours. wondering if I can fix it by reflowing the solder joints..maybe its just a single joint that got loose. I gotta replace a couple of broken keys as well..don't know where I will get them from?? will try fix the jack issue first, what size jacks?? was it 2.1mm?? I was planning on taking to the electronics shop and get as matching jack for the dc walwart

[@LearnLizard]

Reflowing the solder is tricky. Its hard because the paths on the board are so tiny and I'm always afraid I'm going to damage a component. Plus it will probably crack again after use. There is a set of replacement x-50 keys on eBay right now. (I find most of my rare parts there) Regarding the jack, I bought a new male/female pair and replaced the male plug on the power supply because Korg uses a weird one that was difficult to find a panel mount female jack for. Good luck! (the x-50 in an awesome synth)

[@raindogred]

@@LearnLizard good point, replacing both male and female ends makes sense..yes as long as they match, the size is not an issue...good tip. 3 pin dc jacks have always confused me. i recently figured out how to identify pins with a dmm and that extra 3rd pin has continuity with the + pin, and it used to allow connection of batteries as well as the jack in things like effects pedals etc thanks heaps, i will track those replacement keys on ebay cheers

[@Gstation9]

Nice - I got 2 adapter problems. They both work intermittenly and go out. Don't know if it's a Adapter problem or a jack problem. How do you tell which is bad ?

[@LearnLizard]

If you have a multimeter (you can get them really cheap) you can put the leads on the adapter's barrel jack and see if the current coming from it is steady. If it is, it's probably the jack on the device. Good luck and hope you get it figured out.

[@KitCotter]

Mine's a Yamaha Mox6, but same prob. A friend repaired a Motif ES rack I have w identical prob by simply re-soldering where the jack connects to pc-board, so I'm gonna try that first, case it's just a dry-joint again. If that don't work, I'll install a whole new jack. Thanks, Bro !

[@LearnLizard]

Good luck re-soldering to the board. Thats definitely the quickest and easiest solve as long as the stress of the jack doesn't crack the joint again. Appreciate you watching!

There are so many different kinds of of DC jacks its always a challenge to find the correct male/female pair. I have a Universal adapter with multiple tips like this: amzn.to/3sCQQwg You can start off trying to see if the correct tip and voltage will work with your device and hopefully avoid any complicated repair.

[@mchaywood83]

Could you explain a little the testing if which is positve vs negative, like what your voltmeter us set to and what it should read?

[@LearnLizard]

The multimeter should have a setting that measures DC Volts. There will be a black lead that plugs into a "negative" jack on the meter and red for "positive". If you have the leads touching correctly (plus touching positive and minus touching the negative) the meter will read a positive voltage. If they are reversed it will read negative. Hope that makes sense and thanks for watching!

Hey Brother thx for the video. Fixed Mine! X50 Did everything the same. Except for the wire. I used 20gauge to connect the jacks Keyboard works. However it seems to get hot. The chip where the original jack is. Any suggestions?

Certain chips get tend to get a little hot - within their normal operating temperature. I'm guessing its OK- moving the jack shouldn't have effected it. Glad you got it working!

Ouch! Does it respond in any way when you try to power it up with the correct power adapter? If there is nothing you may have damaged the internal power supply circuitry. If it powers up at all but isn't working correctly you could try doing a factory reset. Depending on what it is, it might not even be worth trying to fix. Sorry I'm not more help and sure hope you can figure something out.

[@LearnLizard]

I would first try cleaning out the jack- with compressed air (or other blower) then with rubbing alcohol on a q-tip. Also sometimes you can bend the connectors on the plug itself to make a better contact. (thats assuming the power supply is still working and hasn't shorted out) You can test that with a multimeter to make sure. Hope you get it working!

[@iansanchez1470]

I have a DMX Lighting Controller that looks like the Lixada Show Designer, It has the same issue with the DC Power Jack as shown in the video. I opened the Controller up and took out the screws on the little circuit board where the power jack is, it didn't came out because there was glue so strong that I couldn't pull it from the case and i'm afraid to break the board, how to I take the little circuit board off of the glue without breaking the board

[@LearnLizard]

Can you solder new wires to where the connector is soldered to the board without removing it? That might work. I've loosened up stubborn glue with a hair dryer in certain instances, but you have to be careful that you don't get any of the components too hot. Hope you can make it work!

[@fierybones]

A couple additional things, specifically about the X50 power jack. I was not able to find a replacement for the keyboard's EIAJ IV jack. That meant I needed to replace both the jack and the power adapter's plug with something else. I used a standard Boss 5.5mm jack and plug. Also, the video doesn't show the keyboard's shielding and it also is a "gottcha" waiting to happen. If you use a metal jack like he did in the video, and you wire it in normal center-negative polarity, then the outside of the jack will be positive and will ground against the shielding. I worked around this by putting a large piece of heat-shrink tubing around the jack's body after I'd soldered the wires to it and installing it (before wiring the other end of the wires to the circuit board). I also folded the shielding back so it couldn't brush against the nut holding the jack in.

[@LearnLizard]

Thanks for those additional notes. Yeah, I replaced both the jack and the power supply's plug as a set. The big foil keyboard shield came out easily for me with no issues, and after years now, my x50 is still going strong!

[@phogstr]

Update: Repair shop said my power supply was bad…which they swapped out with a good one. However, back of board where power cord goes still gets pretty warm…but at least it’s working. Thanks for taking time to reply. 👍

[@travisreinert]

I just got thru doing this to a couple of my X50s and I used the area right by the order of the keyboard on the far left for my new Jack. However, this jack/keyboard is wired center-positive so the outside of the jack should be just ground so touching the shielding should not matter. However better to be safe then sorry.

Hi , thank you , but i have another problem with my x50 : i can hear a high frequency sound coming from my keyboard next to the power button ( but it's not coming from my power charger ) the sound disappears few minuts later , and when i play with high velocity , sound comes again . the sound is VERY annoying what do you suggest ? i have my x50 since a lots of years but it works perfectly .

[@LearnLizard]

Hmm- Is the sound actually coming from inside the x-50? It could be coming from a transformer or ceramic capacitor on the circuit board that is failing. If you are adventurous you could try to identify and replace the cap. If its a transformer it could be impossible to find an equivalent replacement, but you could try coating it with silicone rubber to deaden the sound. Or just wait until you get older like me and you won't be able to hear it at all!

I have a broken jack that gets no power at all, so I’m not sure how to determine the polarity of the leads without trial and error. If I guess, and wire it up one way, how will I know if the polarity is correct or not? Thanks for the video!

[@LearnLizard]

Lots of times the circuit board is printed with a tiny "+" or "-" so that is one way you might tell. Or you could try getting a schematic and deciphering, but that can be tricky. I would probably just take the 2 raw wire leads from the power adapter and try touching them to the circuit board to "trial and error" which one is which. You run a risk of damaging the circuit board but most circuits are protected and can take reverse polarity without being damaged. Just know that you run that possible risk.

[@BrianSauerMusic]

@@LearnLizard Thanks for the reply, I think I found out how to do this; using the resistance setting on my multimeter, I touched the pad in the existing jack and each solder point. The one showed a number, and the other one showed OF, just as if there was no circuit, so I was able to conclude that the front point is connected to the pad, and the back point is connected to the pin.

[@LearnLizard]

@@BrianSauerMusic Well that seems like a MUCH better way to do it. Thanks and hope that helps someone else with the same problem.

[@imKufu]

How do you find out which one is positive and which is negative?

[@LearnLizard]

You need to use a Multimeter. You can buy really inexpensive ones on Amazon. You set it to measure volts and put the red lead on one wire and the black on the second wire or jack connection. Then you read the meter to see the polarity. (It's easier than it sounds!) Good luck and thanks for watching.

Sure- most multimeters have a "+" and a "-" lead (usually red and black) If you set the meter to "DC Volts" in a 0-25V range, you will know the positive and negative points on the board when the meter shows a positive 9V reading when the leads are touching those points.

Did the wire break on the AC adapter or did the jack break on the keyboard? I've broken SO many AC adapter cords :( Its easy to solder the wires back together- just make sure you don't reverse the polarity.

🙏* * * HELP please! * * * 🙏 Hi, Steve from LearnLizard, once again at first many thanks for your helpful hints solving this known problem on the KORG X50! I also had this damage like many other users - my instrument is 16 years old and I used it often. According to your advice I tested it directly by soldering a 12 V wire from the power pack to the two contact points on the circuit board (correct polarity, 12 V measured). But after powering on, the X50 does not come into normal working mode. Only the display is backlit, but no text is shown. This happened already before - after wiggling the plug was no longer successful in supplying the device with power correctly. Apparently the small adapter board has got any defect additionally? Unfortunately you can hardly get this module anywhere as a replacement since the production has already been discontinued. What to do now? 🤔 Can it be perhaps that a predetermined counter is built in to refuse the function after 16 years and xxxx hours of operation when reached? The X50 has never been broken and has always been treated with care. I really want to keep using it because I am really satisfied with this synthesizer. I'm very grateful for every further tip or hint! Thanks in advance! 🙏🙏🙏

Hi- I'm sorry to hear about those problems. Yes it sounds like there might be some additional component failure on the circuit board. I don't think there is any built in counter but I do know that delicate components can fail after years and years of use. Your best bet might be to find a used one on eBay. Sometimes I have seen them go for very small amounts of money. Good luck!

@@LearnLizard Thank you so much for your answer, Steve! This little power board is indeed heavy to find, also at eBay quasi not. So I try to substitue it in a selfmade way. I have measured the 3 voltages that should be 11,5 V / 5 V / 3,3 V. Especially the 3,3 V Output doesn't fit anymore. There are merely 1 V. That declares, why the display is backlighted but nothing to read inside the screen, also no buttons are lightened up red after Power On (the ICs apparently don't get their operating voltage of 3,3 V for digital empowerment). So I ordered a Miniboard (DC-DC-Converter) which steps down from 12 V to 3,3 V (adjustable). I hope this will help since the other voltages are correctly present. I will report about my efforts and success, so the other readers here can benefit from it. The delivery of this little Converter board will last up to 3 weeks though. I bought it in a 5-pack (special offer), so I will have sparing parts in any similar cases ... A price of under 10 € is fine for that 5 pieces together, isn't it?

My power jack on my Orange Micro terror broke and it's super janky now :( can't fix it myself

[@Crazylegoman3791]

Me too, but I don’t know where a radio shack is near me and I want to know if I can do something else to keep it in place.

You may be able to fix it by just soldering a new plug on the power supply (without having to open up the keyboard and replace the jack) I hope so!

You can buy a new jack and replace the broken one if you follow the steps in this video. The X-50 is a great keyboard and worth the time and effort to fix!

I’m tryna get my korg trinity workin again and this is exactly wht the problem is power jack is disconnected from a red wire

[@cyrillusventus1]

how i wish to have same for my korg MICROX :/ who has same issue ... but it s too complicated for me, i asked to change this plastic shit to a repair shop they ask me 80euros only to change the plastic part to have same issu in the future : NO WAY... this idea of metal is really better ... but i cant do it .... i m not skilled for that. good job !!! my new MODWAVE is also ship plastic but KORG did something better and this kind of problem wont come normally .... but i regreat my KORG microX i can use like that but if i move machine can turn off, sad..... +1 people who put -14 cant probably do it ... lol like me but for me it s a big +1

[@LearnLizard]

You probably could do this although I admit its a little bit scary. If you just solder a wired jack to the circuit board (or find a friend that knows how to solder) you could just have the wires and free jack come out through the back hole. (no need to drill and mount a panel jack) Good luck- The Micro-X is a great synth and worth rescuing (I used to have 2 lol)

O man i am really bad in handywork.. wat type OF BATTERIES fOR A KEYBOARD

[@LearnLizard]

Hi- I'm not sure exactly what you are asking. A keyboard like this takes more power than an average battery pack can supply-- so you need an AC adapter plugged into a wall socket. Yes a project like this can be a bit tricky especially if you have never soldered!

[@terryfauzifan9459]

[@LearnLizard]

@@terryfauzifan9459 Yes- and that's a more likely chance of what is wrong. You can usually find replacement adapters on eBay for pretty cheap. (best option if you are not good at soldering wires back together)

[@rushingaming8347]

why would't you just re-solder the broken piece back together?

[@LearnLizard]

The old jack had 3 tiny pins that that were soldered directly to the circuit board - Its nearly impossible to solder a tiny pin back together. You could buy an identical jack and re solder it to the same circuit board but I was afraid of the same thing happening again so decided to bypass the jack entirely.

[@link1day]

The problem with my keyboard is described at the beginning of this video kzbin.info/www/bejne/Y6q5ZJl9n6Z3iJo - your method appears sufficient - between that video where he installed the power supply inside and yours where you more simply installed a new power jack - are these the only two possible methods?

[@LearnLizard]

I think the very best way might be to buy a female connector exactly like the one that is damaged and replacing it with the new one. (thats what a professional musical repair shop would probably do) The tricky thing about that is not only finding the exact part, but when removing the old one you risk damaging the circuit board either form heat or stress. Plus I didn't want to have the same problem again in the future!

[@rokinrandy]

So that’s a newer korg. Wow.

[@LearnLizard]

Korg released the X-50 in 2007. (hope I didn't say "new" in the video lol)

[@maxximusoralo2516]

Wouldn't it be much better and easier to use a replacement jack socket instead of drilling a hole in the keyboard?

[@LearnLizard]

If you could find the correct replacement jack you would have to desolder the old one from the PC board and then solder the new one on. Not only is that a very delicate job (with the risk of damaging the adjoining components with too much heat) but I was afraid that the exact same problem would happen again with the jack cracking the solder joint. I know its crazy drilling the hole but it definitely worked!

[@maxximusoralo2516]

@@LearnLizard "To each his own...." but its not that complicated if you know what you are doing. Thats all I'm saying. 🙃

[@jimbob4217]

@@maxximusoralo2516 Its a nice solution, you can add a more standard power jack

[@Boogieplex]

Why wouldn’t you just swap out the same dc input jack right back on the board? Then you wouldn’t have to drill. I came here cuz i need to swap that exact dc input jack on my wah pedal, but ive never swapped components on an actual pc board.So i guess i hafta keep searching KZbin.Any tips to share? Again, im curious why you chose to make a custom jack instead of just replacing the dc input jack?

[@LearnLizard]

The reason I added a whole new jack is because the way Korg designed this is flawed (IMHO) All the stress of the the plug in the jack is put on the tiny connector pins that are soldered to the PC board. I wanted to make sure I had a solution that wouldn't break again in the future. Appreciate you watching!

[@Boogieplex]

@@LearnLizard Makes sense! I actually found how to fix it myself. There is a small metal plate inside the input hole itself.Its supposed to be bent in a “U” shape in order to make contact with the power adapters plug sleeve as it enters in. apparently mine flattened out over time, not making contact with the sleeve.I took a safety pin, and with a pair of needle nose pliers, i bent the pin in the shape of a hook. Then inserted “hook” into metal plate and bent back into a “U” shape. Im guessing this wasn’t your problem, but im happy we both fixed our problem.thanks for the reply.

[@MotoJohn]

Why not just replace the pcb mount female plug like-for-like? Or at least remove it entirely and mount in the existing location. Possibly would have been able to repair it as it was anyway (but can’t say without seeing how it was broken)

[@LearnLizard]

A couple reasons- it's not a "standard" jack size and I wasn't sure how to find an exact replacement. Also, I was worried about damaging the circuit board with too much heat (I'm not the most skillful solderer) And finally, all the stress is on the mounts of the jack and I didn't want them to break again. It was much easier (for me) to just solder leads to the board and use a standard jack (that fit my standard power adapter) I admit it was a little awkward to have to drill a whole new hole in the case, but it's still working great after a lot of use.

[@jimbob4217]

@@LearnLizard Replacing the old one, it would probably break it again, like you I added a 5.5mm 2.1 jack which will last a lot longer. plus easier to find an adaptor!
