Hi all,

i fixed a A1708 which was not working. Not its booting but the left speaker is making buzzing and sizzling noises. I added a short video to show it.

I already reflowed the audio codec chips but that didn't help. Any ideas what to do?

Sounds like your fan is rubbing. Disconnect the fan connector and test again without the right side fan running.

Hello mon2,

will try it later but the sound comes right away when i Start the MacBook and doesn't come with speaker FLEX disconnected.
