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

    Not sure but it is rare to ever hear a play:3 issue. These couple here are about only ones ever heard of.

    Does anyone know if Sonos have modified the board in newer Play3's?. I've just bought one and this doesn't bode well!.

    I should say that my own 3 is several years old and its likely that, as this is an inherent design problem, that it has happened several times and Sonos has designed this particular issue out of the later versions. So i wouldnt worry too much

    Sonos will exchange (for fee if out of warranty)

    https://www.sonos.com/en-au/contact/contact-options

    Where did you get that information from? They were not willing to replace mine for free at all.

    N2GO, he said "for fee", not "for free".

        I have a play 3 too but not sure of the age. Would anyone recommend I proactively check and swap the caps before things go wrong? Anything else need doing at same time? Thanks

            Same part date, same issue. I'm going to speak nicely to the electronics guys at work.

              Hi
              Just found my play 3 dead !
              So same problem nearly a hole through the PCB next to the caps
              I have a done lot of repairs in the past on PSUs with (Bad Caps) so should be an easy one as I also have a lot of soldering experience
              my electronics knowledge is pretty basic
              Am I right In thinking i can just replace the rectifier bridge and caps next to it ?
              If so I’ve just Ordered GBU406 (GBU408 discontinued with RS) and some caps to replace the 400v 33uf ones,
              I’ll change these then get back to this forum over the weekend unless anyone can suggest any thing else I need to do in the meantime ?

              Thanks

                Oh and I chose the GBU406 800v as it’s the closest comparable component spec
