Re: Sonos Playbar No Power (again) after successful repair
Thanks. Would you happen to know the cap specs? Unfortunately my only pics don't capture it.
It's all put back together at the moment and would like to get a replacement ordered right away so I have it ready if it's indeed the culprit.

Sonos Playbar No Power (again) after successful repair
My Sonos Playbar wouldn't power on, a typical power board issue.
I tested the rectifier and the MOSFET with a multimeter. I had to desoldered the MOSFET to ensure I got an accurate reading and it tested good. Used fresh thermal paste for the heatsink and resoldered it to the board. The rectifier tested good on board and wasn't removed.
I replaced the two 400v 100uF capacitors that looked suspect and know to fail. The ESR meter table doesn't have a 400v capacitor listed so I just replaced both with the same. The smaller capacitors tested good with an ESR meter on board....Last edited by rotorrocket; 03-16-2023, 08:14 PM.

Re: New Members - please post your introductions here
Hello from Arizona.
Been looking for a new hobby. Always enjoyed car repair but it gets too hot in the garage during the summer months. To fulfill my desire to fix things, I figured repairing electronics would be perfect during those unbearable hot summer months.
