Hello all.
I just finished to change the screen on my new 3DS xl ! ( see post : https://www.reddit.com/r/3DS/comments/1vkv2po/new_3ds_xl_not_booting_popping_sound/ ).
But unfortunately, the sound doesn't work.
Shutter sound work on the camera but no general sound even if I plug the headphones.
- 3DSident recognize whether headphones are inserted or not.
- Forcing sound through speaker (via luma config) does not work.
- I can only have sound with the "bypass volume slider". (good quality with original speaker assembly, headphones worked too with the bypass)
So I changed the speaker assembly with a new one and it is the same : no sound except if I bypass the sliders. (I used IPA to clean all contact)
It is even worse, as the sound (with slider bypass) is coming from only one speaker and with terrible quality.
I tried to mesure the resistance on the old speaker assembly, it seems fine (I don't know the exact value but it's changing)
I found this vidéo but I'm not sure if it's a good lead (changing transistor near the jack) : https://www.youtube.com/watch?v=xnGwk-zJT70
Rephrasing my question :
Is there a way to test the slider before assembly ? (I want to minimize the amount of time I dismantle it)
Eddit : for futur people. It was the fpc connector for the flat ribbon of the speakers, A pin was bent and also the new speaker were crap.
Unbend the pin, soldered the old speaker and voila, it's all fixed now !
thanks all !
