**I am unable to work on your Sonos unfortunately. This video is the best I can offer**
This Sonos whole house amp system (model CTAZPUS1) was brought in because it stopped turning on. I found that it is built like a puzzle... I had a heck of a time getting it apart until I found the top was removable.
Looks like it was hit by a surge that took out the switching Mosfets and the pair of diodes on the secondary side. Amp chips seem 'ok' so far.
