Two Blue Tooth Speakers With No Sound Repaired
A guy next door was waiting for me outside the shop and wanted to get his blue tooth speakers fixed. He has plenty of them and today he brought me two for repair.
I have repaired a lot of these and they are very easy to fix.
With a flat screw driver I popped the black cover open and right away I could see the fault.
The wires were not loose but they were twisted together and that is usually the problem with these devices.
These are very thin wires and they are isolated. To add solder to it you have to use heat and when the color on these cables starts to change just add fresh solder and flux. The process is done and you will see solder sticking to the wires.
The final thing to do was to solder the wires back to the pins of the speakers and you are all done.
I connected it to my iphone and test the sound and as expected the sound was loud and clear.
Mission Accomplished.

These wires indeed are very thin and it is a wonder they didn't break. Although they are Bluetooth speakers we still do need wires.

The wires of the headphones are so thin that it just melts on heating. I normally dislike to take up such jobs! In some, there will be a thin lead sheet, which melts on touch by a hot soldering iron!
Anyhow, you have done a good job as usual!

Parasuraman: yes they are very thin but when I control temperature and use a low melt solder, everything will be just fine. thanks man. have a blessed day

Good job done,as well as given good idea.Twisting of the wires is cause of the performance. My doubt may please cleared.

babums: thanks. yes twisting of wires might cause this damage and also the pulling of the speaker by the customer usually put a lot of tension on the cable so twisting the wire inside will make less tension on the wire and hopefully it will last longer and so far there is not complain by the customer, he lives next door. have a blessed day
