Thank you for that information. Later today I will reassemble the sub and hopefully it will turn on and not "fire up "

I found Q16 to be a 2n2907

Good luck!

Let me know.

UGHHHH…..Majic smoke again.  Took out R37, R77 and Q10.  Now measuring a short both ways on D15, Google search for B280 shows up as a shotkey diode. Im confused as to D15 being a zener or not.

Can I stick a 1N4007 in place of the B280 for a test to see if it will power up at all ? 

Hi, try to see this:

You can ask him.

I think you need to change D15, Q10, R37 and R77 before power on the sub.

Thank you.

I did replace all those components that you suggested. I also replaced Q16 and D15 with a 2A 100v  diode (not a schotkey.)

It has now powered up and I did a factory reset which was successful. I think I've fixed it but will not know for sure till I can get the sub back to the rest of the system

Thank you so much  for your help and the help from the rest of the Sonos community. I will update the forum after I've confirmed its fully functional.

I’m very happy for you!

Same for me, I replaced yesterday D15, D16, Q10, R37, R77, C85. The Sub back to live.
