Sonos Play 1 with blown cap and fuses

[BMCappelletti]

Hi there.
I was given a Sonos Play 1 (yeah, very old) that does not turn on.
Checking the main board, I can see a blown cap, that connects to two blown fuses. Right by the LAN port.
Where should I start looking for the main fault?
Thank you.

I see those are gone, along with the cap.
Imgur works just fine here to see full image.
Try these links.

desolder the network transformer and meter the coils in it.

if it wont boot without the transformer then it may have fried the network chip - i hope it's seperate and not part of the cpu!

Would it be the one with the number 2 next to it, with TP366 printed between its legs on the back side of the board?

cant find it in the photo!
desolder the network transformer connected to the burned bits and then meter the pads on the board to see if other stuff is shorted.
i presume you already did the finger test to see if any chips are cooking

I did use a thermal cam and nothing seems to get hot.
I'll try removing it later and check for shorts on the pads. I'll report back.
Thanx.
