How To Fix Ultimate Ears Wonderboom No Power/Not Charging 

Thank you man, i just bought one for 15$ brand new, not giving life sign. And fixed as u said. Now party can go on ! ❤️

Brilliant, this worked for me as well, my first attempt was to just remove the cables hoping it would do some sort of reset but yeah, the capacitor was the culprit. I do recommend taking out a side speaker for easier wire handling, but there is a seal holding it together so it takes a bit of pressure to remove.

Excellent solve. Another decent item kept out of the landfill. Thank you!

My problem was "No power, No charging". I removed the capacitor as explained in the video. This solved the problem. In the meantime, I had bought another Boom box. Now I have two that I can connect together. Very cool ... Thank you man !

This worked! Thanks a lot! And if you do not have a soldering knife, just heat up a screwdriver!

INCREDIBLE! Thank you SO much for this video. I was ready to get rid of my speaker because it wouldn't charge or turn on no matter what I did when I found this video and it completely fixed everything. I removed one of the speakers on the side and it helped a lot with adjusting the wires as well as using heated tweezers to pry off the transistor at the end. A few things need a bit of pressure to remove but in the end everything worked out perfectly and my speaker's working good as new!! Thank you again!

Brilliant, 5 stars for this fix, I was just about to replace mine when I saw this video. It has worked but am a little confused that it now works having removed the capacitor! Many thanks

You, my friend, are the man! I would never had known how to fix this- Thank you!!!

Just did it!! Havent done anything similar in my life. I was pretty desperate so just tried it. It was quite hard wont lie, mostly the part when having to remove the transistor, I heated up with a lighter some tweezers and finally got it. Worked out perfectly, thank you!!

I'm so thankful to have found this! Feels great not to have to buy a brand new one just because of that tiny peice of metal. Thank you so much

Thank you mate, it's working now. You made a breton guy happy 😊!

You are a legend! Thank you so much. Feels like a the most blatant form of planned obsolescence which is sad but gives me hope that the internet can be a amazing place to overcome that!

Bought this speaker 4 months ago and this exact thing happened. no lights, not charging. contacted ultimate ears and they walked me through some troubleshooting and nothing worked and they were wonderful and honored the warranty and sent me a replacement. I have NO experience taking apart electronics but with a replacement in hand I realized I have nothing to lose, I tried this fix and it WORKED perfectly! Don't forget to unclip the bottom cap to pull the whole inside mechanism out and definitely remove a speaker to undo the wires! Looks like the seal on the speaker is to keep it waterproof so don't expose it to water after this fix! thanks so much for sharing!!!! It absolutely saved my speaker from the trash and only took 30 min for a newbie!

Cheers bro, worked very well. Super happy!

The element on my PCB where placed in different position then the one on the video. And without experience I thought I was cooked. The capacitor was hard to find and harder to recognise, so I pick up what I though it was. And boom its actually work. I can get full charge on it. Dude you're a genius

It WORKED, thank you verry much, although it took a lot of time to open the speaker, at least it worked

Worked an absolute treat! My pasty hands didn’t help but all is good!

Thank you so much, I have never done anything like this before and I got my speaker to work!

Thank you so much, it worked!! This is obviously a common fault that needs to be fixed by the manufacturer.....

how do you know which one is the capacitator? our models are identical but the boards look different.

My speaker just died so I tried this out - it worked!

Es funktioniert, danke. Habe das Bauteil mit dem Dremel weggefräst. Der Speaker funktioniert wieder einwandfrei

This fix worked for me. Thank You!

Totally worked, 1 screwdriver and a scalpel to GENTLY prise the right piece off. Recommend tweezers for the connectors and definitely had to cut remove the speaker as connectors were so short.

Worked for me too! Thank you for sharing!

Thank you really much !!!!! I never thougt that this box ever gonna play Musik again but your video was grate!! It was a little bit difficult with the Kabels but i made it.grate video!!

C'est top, bravo pour ta publication, ca re-marche nikel!!!! Incroyable!!!! Your are the GOT

I bought mine’s from Argos 2 months ago surely it’s still under warranty? I’m absolutely hopeless at things like removing a capacitor especially since I got thrown out of technically drawing, woodwork, metal work and art at high school. I wouldn’t even dream of taking my Wonderboom 3 to pieces. What would be my chances of taking back to Argos for a replacement? TIA

Thanks a lot for sharing this! Thats one more Speaker saved from premature disposal. How did you find this out? Really appreciated.

Thank you so much!!! I wasn't confident at first do to this by myself as I know nothing about this area, but it turned out to be a great challenge and now the wonderboom is working fine Only thing is I have accidentally took out one capacitor, bigger one, written E9, 220, 16V on top. Any idea if it's bad? Thanks again! Amazing video

Wielkie dzięki, działa jak należy 😃

It worked! Thank you so much!

Wow man! Thank you so much, it worked😁

Did you maybe fix the wonderboom 2, the same problem, but the board is different. Can you help me?

I could fix 3 out of 5, 2 of them were charging but died when reassembled and turned on for a second. Maybe another capacitor died without the other one, how likely is it that the one above died too? And how exactly did you find the dead one?

how did you all do to remove the capacitor?? with some plyers or you have to use a soldering iron?

You are fantastic mate

hi, i have one Ue Wonderboom 2 speaker, the speaker is dead, not charging anymore, no led appears, i just bought it 1 month ago can you help what's wrong with my WB 2 please ?

I have this problem could I send to you to fix how much do you charge?

Thanks so much! Worked!

My Wonderboom 2 plays for 3 hours at 80% then dies. Dead battery. Do these speakers use an 18650 battery I can replace with a higher amp version? Will this kill the charge controller chip?

Hi Clint, Just bought a couple of these speakers but neither are charging. Would you be able to tell me how/why removing that specific component repairs the charging fault? Thanks, John.

This fix works 😀 thanks for sharing

What does this capacitor actually do? Would it be the case that it only just need disconnecting and reconnecting the battery pack? has anybody tried this without removing the capacitor?

worked for me, thanks a lot

thnx buddy.... another one fixed !

What if it looks different when it’s opened up? I have the same model I thought, but it looks different. I see PB2 E322995. I was going to try and test capacitors to see if one is shorted. 🤷‍♂️

Hi, would you know how to find a replacement battery for one of these? Thanks

Thank you worked great!

Hello, My wonderboom2 just; stopped . I still not able to turn the power on. No light no sounds no music. The audio IC is gone but i don't know Where can i fix it ? Which Audio IC wonderboom2 actually use?

What if both lights are on , on top ? Should I do this on the video as well ?

Thank you very much !!! It worked out pretty good !!! 😀👍👍

Its working thx 👍💪

Hey bro I have one of the Wonderboom an I do the same thing you do and it works perfectly but I need a capacitor for the sound to produce better. If I rise the Volume up it stop an play again it do it for 1Sec

but you think removing that capacitor should fix this kind of problem when the speaker shows no sign of charging?

Big help. Thanx :)

I don’t get it ¿is the device working properly? I noticed in the video that the music pauses randomly. Well, I have a Steren Boc 830 speaker and I have the same problem, the music starts to shut down or pause when I go a bit further of my phone, but I have a Wonderboom 2 that is working very fine, even too far from my phone. I think it’s a Bluetooth connectivity issue, and I don’t know how to reset the Steren Boc speaker to its factory settings. If somebody knows how to fix it, please let me know. Kind regards

is this the first version?

+1 Thank you bro!

how do you remove the top in 1:50??

Thank You, I fixed my wonderboom…

Thank you very much sir I just fixed mine had the same problem and now working thank you again

I have an UE Wonderboom, having the same issues. I took it apart but my circuit board has a different layout. If I send you a picture can you identify the faulty capacitor?

Love “Heroes Tonight “ 💕

Would this cause anything damages overheated or burn the speaker??

My wonderboom board is set up differently, I can't identify the capacitor on this boards. please help,

Damn it's working 🔥

Amazing! such a tiny piece of metal that didn't need to be there. It worked, thank you! why is it there anyway?

Let me see if I understand, you removed the broken capacitor, but you don't replace it with a new one?? I have a unit just with the same troubles, no power, no charge and would like to attempt repairing it. If it is just a matter of removing the short capacitor, great. But if I need to replace with a new one, which one should I buy??

Thank you!!

well i removed the capacitor and the speaker is able to charge, but when i press the power button it turns on for half a second then shuts down (but goes back to charging tho). I have the same board as you. HELP!

@Clint Lipscomb - my Wonderboom looks like yours but had a PB2 board variant like @therandomgermanguy. It wouldn't charge with 2 different cables, but did have enough power left to briefly turn on (flashing red) then back off with tone like @Andjru Werderitsch saw. I removed shorted capacitor C31 which is on the edge of the PB2 board, next to the CN9 connector. Now my Wonderboom charges with 2 out of 3 cables & works fine at all volumes.

RHIS WORKS 100% FOR MY SPEAKER

Mine charges for a short time then stops. Do you think by doing this it would help

Wow! That's so helpful, why does it blow out though?

La mia no carga.... Y quisiera saber si tienes un video con una mejor explicación

Hi there, I don't have a soldering knife. Is there another way I can remove the capacitor?

MUCHAS GRACIAS POR SU TIEMPO

Clint, Thank you. I was able to do this repair and successfully fix one speaker, and has been working great ever since. I have a friend with a broken one also, and attempted to fix that one too. however the control boards are different (PB2). I was wondering if you had a similar fix for that Speaker. Its not a UE wonderboom 2, if you were wondering.

I can’t locate the ic on the board

Does it work for wonderboom 2? I can't power on my boom 2 speaker and neither can I charge it now. I saw your video and im thinking of doing it though I'm scared I'll mess it up more. Please reply, 😁

Look like the new ones have no access from the top. Any idea anyone

Hi is this applicable for ue boom 2 speaker? Thank you.

Does this work for the wonderboom 2? I have the same problem 😭

weldone sir

RU-vid suggesting this a month after I repaired it 💯

I'm just about to do this, but I have a question. Why would this capacitor prevent the speaker from working? Also, my unit doesn't show signs of charging, but still has enough power to show "red light" then it powers off. Is the capacitor still the issue?? Thank you sir.

Mine has a different board. How will I know which capacitor to remove?

is this wonderboom old or flashy? because I opened it up, and it wasn't the same

What is the function of that capacity and what caused its failure?

What is the purpose of that capacitor other than to break?

Dang, my speaker is on but dying and won’t charge. This sounds complicated, and I’ve never been internal-hardware savvy, but maybe I’ll give this a try.

Please can you describe the chip i will remove please

I'll give it a crack. Mine is the newer version, but as you said, it could be the same issue.

Wow you're an actually electricity man

my speker changer 1 hour batery not good

How much battery mah does it have?

Hi friend I just disessmble the cap. Right now I am reessemble the speaker 🔊 then I will right again. I hope it will be solved :)

Hi I hope you can help me, mine broke yesterday, weirdly it would not turn off, so after 15mins it shut down, now the turn on button wont turn the speaker on, it still charges, everything else seemed to work fine except for the power on button... do you know how to fix this ? please let me know or anyone lese on here... thank you

My panel looks different how can I show u
