(No audio device) Macbook A1707 2017, 820–00928a

Hi,
I have a MacBook Pro 15 A1707, board number 820-00928a,
It's have an issue with the audio, In settings it has no audio output device,
I've tried to plug headphones and it didn't recognized it.
I have a schema for the board but it's hard for me to read it. I have some practice and I can solder skills, but it's hard for me to do some troubleshooting, but I know how to use multimeter, just please tell me in what mode need to fest the component [ diode mode, continuity, ohms mode, etc.. J

Thanks

In the name of Fauda (Netflix) and Jaffa oranges, will try to help...

1) you will need the boardview file to locate the parts that are shown in the schematic.

2) What is the history of this laptop ? Was it brought in for repair ? Liquid damage? Any visible corrosion on the logic board ?

3) Watch this video which is exactly on topic for your case. You should be able to check the voltages like he is doing but the repair may be a bit complex unless you have experience with WLCSP (very tiny) component repairs. Start with the voltage checks for the audio section.

Wow man! Much appreciated!! Really. Wow, I’m so thrilled by your reply. Thanks!!

It will take me some days to report back, as I’m an individual, i really don’t know the history of this laptop, but I do know this:
1. It has the Flexgate which I successfully repaired myself.. so yes, I can do tiny components

2. I saw some caps near the edges of the board that doesn’t look so good with some indications of corrosion, I cleaned it all with IPA, and the laptop is working now as my main laptop.. so it’s working great except some issues.

Thanks for your reply, and I will get back to you
