Sonos Connect ZP90 - schematic power supply help needed

I’ve hit a hurdle fixing my Sonos connect so looking for help. After removing the power board I could tell the fuse had blown and a NTC thermistor had failed. I also suspected capacitor C206 (1800uF, 6.3V) which appeared to have bulged top. I do not see any other signs of distress so I replaced all of these components and upon power up the fuse immediately blew.

So there is clearly something else wrong besides these parts and need some advice what I can check. I have searched unsuccessfully to find schematics?
