820-2879b no headphone jack

[Yoel Ren]

This macbook have chime, speaker works normally, but if i insert headphone, it can detect the headphone but the sound is nearly non existent, but i can hear the song’s bass thumping a little, what i have tried is removing r6805, change u6700, changing blown DZ6705

If D6705 was blown, did you check L6705?
Also check L6704 and all resistors around U6700.

L6705 , l6704 and resistor all are fine, any chance of bad jack?

Missing sound on speakers, or headphones only?

 

[Yoel Ren]

Only on headphones.., speaker works

Try to clean audio jack first; some videos available on Internet...
