Hi all,

This is my first post so I hope I am using this forum correctly!

I am trying to troubleshoot an issue with a Sonos play 5 (gen 1). The thing has completely stopped working bar the white light. I have had Sonos systems for a while now and have written off any chance of a software fault.

Could anyone help me identify these capacitor like components? (Marked 100 and 200 with two dots on top). I need to test them out.

Thanks,
Alistair.

 

Looks like 10 and 20uh inductors, but hard to tell the current rating.

 

As above, those look like 10 & 20uH inductors, even the PCB shows the component identifier as Lxxx, where L = Inductor.

 

What is the board not doing? Inductors can fail, but in my experience they don't fail that often. You can try testing them for continuity without removing them. If it were me, I would start at the high level. First check if the power supply is working. With all those inductors I'm guessing it's a class D amplifier?
