Symptoms: With ANC on there is no sound in the right earphone. It also seems like right side audio may be slightly quieter with ANC off, but full sound is delivered. Tried: Replace battery Loose connection? Bad motherboard? These things are unnecessarily annoying to tear down.
Hi Unfortunately you might not be far off the answer It could be a bad board ,loose connection or a torn cable Have you also looked at the battery connections to check for corrosion? What I would do is take them apart and check everything for any damage or defects If you can’t find any I would replace the main board and work from there Hopefully this helps Any questions please ask Thanks:-)
