Play 3 Powersupply fault.

Hi,
My Play 3 died the other day and I am just outside my warrenty period 😞 I contacted sonos customer services who did not help me in the slightest. I have now looked at the power supply board and seen that the board around one of the input capacitor has burnt out and or the cap itself.

As customer services won't even sell me a new power board, does anyone have a circuit diagram for this board so i can attempt to repair it myself. ( I am competent with electronics).
P/N: RN-002657 (board number)
Date: 08-04-11

Also has anyone else experienced this fault. I am assuming a power surge has done this.

Many thanks

I guess if you're concerned about its safety you should take it the Trading Standards (UK) or whichever is the relevant safety body in your region.

But I would say that just because something fails in such a way as to generate heat and discolouration does not in and of itself self imply the whole was at risk of fire.

Repaired, luckily the board was not damaged beyond repair. I had to make a new rail on the negative side of the capacitor/rectifier where it had burnt through as it was a sandwiched PCB board with a central layer. I've put in three new higher temperature rated capacitors to replace even the ones that did not blow (they too look slightly enlarged however). Bench testing now for observations.

I have the exact same problem on my Play 3, same code too: P/N: RN-002657 (board number)
Date: 08-04-11. Will follow the guide and replace the capacitor.

Exactly the same problem here. Replaced all three capacitor and bridged the + lead from C306 to the + lead of the bridge-rectifier. Also had to replace the fuse F301 (that little brown cylinder reading T2A). Don't forget to check that fuse. All working fine again. Costs: 10 euro (I bought higher voltage/better quality capacitors) and some hours instead of the 180 euro Sonos offered me to replace my PLAY:3 witha new one...

Sadly I've replaced the capacitor but my circuit board is damaged and shorting, it's getting beyond my meagre skills to repair.

Yep FYI mine just blew and I have a cap blown and the track burnt after the bridge rectifier. It's the same board RN-002657 with a date of 08-04-11. Seems to be a common theme here now.

I don't think 3-4 people make it a common theme.
