Hi,
Recently, the left side of my JBL T450BT over-ear headphones stopped working. I would like to point out right away that I am not a specialist - I just want to repair my equipment. I opened the headphones and it turned out that all the control (controller) is in the right earphone (good enough). I switched the loudspeaker from the left to the right earphone to make sure everything was ok with it - it was working. So I started looking for a fault on the PCB in the left earphone. After the measurement with the meter, it turned out that one of the pins has no current (marked with a red circle in the picture).
I checked the analogous pin (Signed with the same code - SKLP) on the right handset (marked with a blue circle) and the current flows through it.
From this working pin, the cable goes through the headband to the non-working one. I figured maybe something was wrong with the solder (although it looked okay), so I unsoldered the cable and re-soldered (not very neatly, as you can see from the rest). Unfortunately it didn't help. Logic shows that this wire is broken somewhere (maybe inside the headband). What should I do? There is still a chance for these headphones?
