In this video, I'm exploring a broken Bluetooth speaker with an internal battery that was reported as dead and not charging by a friend of mine.
Initially, I suspected that there was a broken wire inside since there was a knocking sound coming from inside but the entire repair turned out a bit more involved when I had to dig into the battery, investigate the circuitry, and end up re-soldering the connector using my hot air station.

Hey man, I need your help if that is okay. I have a MEGABOOM 3 made by UE which after being exposed to water has stopped working. I was under the impression this speaker was water proof, as I have had it under water with no issues before. They also advertise this as a feature in their main selling point. The speaker still turns on, connects to my phone and charges. However, the speaker plays no sound at all. When it first was submerged the music was still playing but the sound was "staticky" and not clear at all. After letting it sit to dry off it then did not have any sound at all. Please let me know if you know what I can do to fix this, or what is the problem for this. I was told by UE they don't do repairs and they said their best offer was a 15% discount, so I am stuck outsourcing for a repair as I don't want to completely replace it. I feel it is a waste.
Thank you in advance!
I'm not familiar with that specific model but when devices get water damaged, what usually happens is that they develop corrosion on the board. To inspect and possibly mitigate this, you will need to disassemble the speaker and look for areas with discoloration and green oxidation. This can be cleaned with isopropyl alcohol that is at least 96%. If there is no damage to the circuit, the speaker might start working again but this is not guaranteed.
How can i fix my omega portable speaker that when i switch it on theres no sound but only power on light?
Check for broken wires. Otherwise it might be an issue with the amplifier circuit.
Profix! Great job!
Thanks! ☺️☺️
I have a Bluetooth speaker, but switch off even turn switch on, it turn off by itself. Any idea why this is happening??
The battery might be gone. When a lithium battery is bad, it will often go undervoltage and the protection circuit will turn the device off.
I'm i Cape town how can i reach you as i'm planning to physical take to you my portable speaker ?
Well we are continents apart so I don't think it will be economically viable to do so. I'm based in Europe in Macedonia.
Very interesting, need some help from you.
Thanks, how can I help?
