Hi,
I'm having an issue with an A1707 MacBook Pro—there's no audio output. Initially, the MacBook came in with a no-power problem, and I found a faulty U6400, which I've now replaced. The laptop now powers on, but there's still no sound.
I've also replaced U6300, but the problem persists.
Here are the current voltage readings:- PPV18_S0: 1.8V
- R6402: 1V
- R6405: 1V
- R6403: 1V
- AUD_SPKRAMP_RESET_L: 1.3V
- PPBUS: 12.6V
