If the troubleshooting guide for the power port hasn't fixed your issue, this guide for replacing the internal power supply 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 spudgerd is great when you need serious prying power, but the regular black nylon spudger or a plastic opening tool should be used whenever possible.

And where do you find a spare power supply ?

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.

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.

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