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

    Thanks to Jamie Taylor. I had exactly the same issue, and exactly the same image.
    They have thermally tied the capacitor to the diode array (which does get hot). Not a good move. The track blowing saves the rest of the circuit.
    Full marks to Sonos for allowing the forum though. Hopefully they'llsee this as a common issue and not put it in future designs.

        i can see nobody want to answer. I was able to open the other unit i have and I had a look at the same board and here is the picture. The part i am looking for is D307 and I supposed it's a diode. the code is AN 97. I couldn't find any information. can someone help me with a suggestion and what I can get for replacement . thanks in advance

          I have a play5 that's completely dead, but after opening it up i can't see any obvious reasons why. I measuring around 325VDC after the rectifier, is that a correct value?

          Hi,

          My Play 3 has also just lost power. I am not competent enough to open/inspect so looking for some advice on possibility of repair by SONOS? I am in Australia.

          Does SONOS do repairs? I have looked over website but it is not clear to me how to contact them?

            My own "3" lasted longer but exhibits the same fault. As it happens I have my own Electronics company and we looked at the PCB (see attached) which has been woefully under-specified and the boards are poorly built. The Bridge rectifier has blown and taken the board and the electrolytic capacitors ( a totally inferior unknown manufacturer) with it! We can repair it but it doesn't say much for the quality of a high end system that has clearly been built to minimum cost

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