Hello all,

i just brought my Sonos back to life.

i replaced as well several capacitors on the board.

my concerns are about the 5 (820uF 35 V) caps.

i replaced them all , but in normal use, or Even in standby they reach temperatures around 55 degrease.

is this a normal situation or is there still some fault ?

what do you think?

happy to get some feedback from you all :-)

The frequency is beyond anything humans can deal with. Are you using a 10x probe? If so, this could be 1.0V/cm.

I’ve not opened one of these units and can’t offer much more insight. 55°C is within the capacitors operating range, but I share your concern. Have you explored the main power supply? Electrolytics are not so good at absorbing high frequency junk.

That isn't ripple (50 / 60 Hz or the switching frequency of the supply) but noise, not likely from the power supply.

Very impressed to say the least!!!

You guys should go into business as a Sonos 3rd party repair option 😊

That might be a more tempting option if anyone has found a good way to make a decent profit on Sonos repairs.

Aside from possibly that one place in England somewhere has anyone heard of any?

There is an EU company.

My Sonos Play5 Gen1 gets hot in standby mode, and there's a background noise when I put my ear close to the speaker, just like when I first paused playback. Normally, the device enters deep standby mode after a few minutes of pause, and the back of the device doesn't get hot. If the back of the device gets hot when you touch it, then there's still a problem.

By the way, when I unplug and restart my overheating Play5, there's a loud popping sound after about ten seconds, followed by background noise. I think it's because the device isn't in deep standby mode, and the amplifier is constantly running, causing the capacitors to bulge and overheat.

Since the amplifier is not 100% efficient, warming of the rear cabinet is normal during music play. After the music stops or is muted for a while, power will be removed from the amplifier resulting in lower case temperature.

There is always some residual amplifier noise, even when there is no input. Typically, at the listening position residual noise is unnoticed because it is much less than room noise. Unfortunately, if the human notices the noise, it will never go away because the human obsesses.
