Einleitung

If the troubleshooting guide for the power port hasn't fixed your issue, this guide for replacing the internal power supply of your Sonos Connect would be suitable to fix the problem.

When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The metal spudger is great when you need serious prying power, but the regular black nylon spudger or a plastic opening tool should be used whenever possible.

    • Once enough of the glue is removed, peel the cover off by hand,

    Careful as the rubber bottom rips extremely easily. Be very patient.

    thnx!!

    Rick Jonkman -

    Does anyone please know what the 4 coloured power wires in the Molex are, in terms of 12v, A rating and + or - ? Many thanks.

    dhroser -

    values are printed on the PCB: -

    Red: 3.3v+

    Black 3.3v GND

    Yellow 14.8v+

    Brown 14.8v GND

To reassemble your device, follow these instructions in reverse order.

And where do you find a spare power supply ?

meh -

You'd probably just replace the 1800µƒ cap, which you can do without removing the board. Leave the wireless card attached to the top board when you carefully lift it out of the way. 99 times out of 100 if a PSU goes down it's one or more capacitors.

Steve Long -

My Sonos was fried by a thunderstrike recently.

More precisely: 3 parts on the power supply PCB: the fuse, that 1800 uF cap mentioned above and some other part that I'm having a hard time to identify:

It's located pretty close to the fuse on the PCB, there labeled whith "TH1" and according to the symbol it's some kind of varistor or thermistor. With the "TH1" label I'm inclined to bet my money on thermistor, some NTC probably.

From what little is left of its housing (green, round with a diameter of about 8mm) its caption once read "SCK 102"... or something similar. But that's all I could find out.

Could anybody tell me more about this part and its dimensions?

When feeding the 3.3V and 14.V that the power supply PCB normaly provides from some lab power supply to the mainboard of the Sonos it works fine. So wether I'll be able t resurect my Sonos depends on identifying and replacing this one little bugger...

Thanks a lot

In my case, the 2A fuse and the MB8S Bridge rectifier were broken. Also my 14V output delivers 17.5V. The zener was not broken so I guess there are different versions.

Dirk de Vries -

Can you lick up +5 volts from power supply black/red?

Robert Bruce -

Hi guys! My connect stoped working so I took it apart and the 1800uF cap was leaky and screwed! So I replaced it.... now all I'm getting is the white LED flashing!! Before a replaced the cap I got nothing at all! Any ideas??

Matt -

Hi guys, hope someone can help - I'm trying to fix a failed Connect but someone already tampered with it (and abandoned the notion). Since the PSU board is incomplete I can't make out what needs to exist where the U3 pinout is (the chip is missing - has 8 contact points). any thoughts? or maybe photos? Thanks so much upfront!

Mike -

Hy Mike B.

I can send you some pictures with my PSU that was blown due to a surge and can't fix it...there is a short...when I plug it in the fuse will blow and i couldn't find the therminator to replace it the one that Tomarang refers in his comment. So if you need pictures of it ...let me know

George -

@ Mike B , The chip is a 5M0165R - http://pdf1.alldatasheet.com/datasheet-p...

nhendley -

Mine has the same 5M0165R chip clearly blown, missing two legs with soot on the PCB indicating a transient spike took it out! Can buy and replace chip but have to suspect other components might be damaged. Sure would love to know where to buy a replacement Powersupply PCB!

sailingmagnus -

@ Matt - sound like you just need to reset the connect. Plug it in with mute and volume up button pressed

nhendley -

I abandoned the connect for a bit as I was having no joy but really want to get it working and sonos won't touch it now as I've already started, originally I was getting a white light but now no light at all, where is this internal fuse I'm hearing about.... and how can I test to see if the power supply is screwed??

Thank you

Matt -

I need to replace the cap as well. What voltage should it be? Thank you!

Scott Hechinger -

My Connect just stopped working about 2 months ago. These instructions are great and probably a little beyond me. Sonos have offered to replace it but at a high price. So would anyone here be willing to have a crack at it for me? Could be a simple fix? Happy to pay? thanks

JamieMac -

really helpful demo thanks and I have managed to remove the power supply. I have 3 questions:

1. I think I have found the 1800uF cap- can I tell from the outside if it is blown?

2. To replace it will I need to solder?

3. If so is it tricky/any tips?

arnoldcb6 -

Following this guide I completed replacement of 1800 uF capacitator but still no power- any other suggestions please?

arnoldcb6 -

Try replacing 5M0165R. It was found blown on the unit I have here, waiting on parts.

kylegp -

Found this video https://www.youtube.com/watch?v=shxvyfY1... that might be helpful to some here. I think the video is in Romanian language, but gives you some clues what to test and replace. Would be great if someone contributed an english closed captioning translation on it.

Hola buenos dias, podria decirme donde puedo encontrar las fuentes de alimentacion para ese modelo de SONOS

Ben Thompson -

Hello please any place to buy a power supply SONOS Connect sorry my english is not good

Ben Thompson -

No need to take off the wifi card for this guide...only disconnect the antennas.
