Re: Sonos Play 1 no power repair

I had the same problem, and applied the same fix. Thanks so much for sharing.

Some notes:

Be careful of the big 400v cap on the power supply input. It discharges very slowly even when the power supply is working... and if the power supply is broken it stays charged for literally days. Use a resistor to discharge before working.

Main symptom of this particular fault is that there is a dead short on the 24v side -- easily measured in the two 35v output capacitors.

As far as I could make out...
