Sonos ZP100 dismantle and possible repair guide.


Userlevel 2
I bought a faulty Sonos ZP100 which had previously been opened. I therefore had no option of a Sonos repair or out of warranty exchange. I couldn’t find a guide to strip the unit down so worked it out myself. I have since written a guide which will hopefully help someone in the future but I accept no responsibility for any damage caused by following it. At the end of the guide I have written a small explanation of the repair needed for my unit which appeared to have suffered a power surge and no longer powered up. Please feel free to improve or alter the guide. Thanks.

Thanks for the dismental guide, finally I can open the box.
I'm having a similar issue on ZP100. After a rebooting the ZP100 it shows up in the controller and only works for around 1 or 2 minutes. And then i still can ping to the IP address of device, but it disappear in controller. I did test, like reserving DHCP IP, changing WIFI channel, using wired LAN, and hard reset, but no one works. Once it disappears in controller, the mute button has no response, IP still can be pingable but no response on URL:"x.x.x.x:1400/status". I can still reset the device, re-add the device, and all operations are normal.

I recall the issue may be occurred after i upgraded the firmware to 7.x, and now it's 8.11. I suspend it may be related to the firmware version,but It seems no way to downgrade firmwall to previous version. My ZP100 is quite old, the hardware version is 1.1.3.2-2, which has the problem with new firmware. do not know if SONOS still have the source to support the bug fix for the old devices...

Hi rosscoundon,

I have had a very similar experience. After a factory reset the ZP100 it shows up in the controller and works for around 1 or 2 minutes. Then the music stops and the the zone becomes frozen on the controller. Then the zone disappears from the controller. The white light is still on, but the LED is noticeably dimmer.

I've gone through the Facebook Messenger process, which failed to resolve the issue. They created a ticket and I was able to get on a call with a technician. He went through a lot of the same steps, but no solution. He recommended sending the device back for an out-of-warranty replacement; however, this is going to cost around £130 for a reconditioned ZP100. This is very disappointing.

Rosscoundon - did you have any luck with your device?


It turned out to be a wireless clash, despite how adamant I was that it was hardware! I recently got Sky Q and there is a conflict in how Sky Q attempts to monopolise the various channels that was locking up my Sonos.

I've changed channels which has helped a bit but I still get the occasional issue

They'll be able to get you started, if they can't finalize the replacement, they'll at least get a ticket started up for you to work with the phone team. It's a great way to have all the notes put together.

Given the predictable abrupt cut-out after a short period of time, any thoughts on whether this is this likely to be hardware related?
Given the unit is quite old, I don't know if Sonos would offer to repair, so should I consider opening it up to take a look?


Sounds like it's hardware related. When it becomes unresponsive, does the unit respond at all to the mute button being pressed? If not, it's locking up and probably a bad unit.

We offer an out of warranty replacement for most units that aren't working right, even if they're 10 years old. One of the big things that makes a player unavailable for this replacement option is if the unit has been opened up. My advice, give us a call or reply back to your incident if it's an email. Don't open the player.

Let the technician know it's still dropping off and they'll take a closer look at if a replacement is available.


Thanks for you reply Ryan. Pressing the mute button has no effect after it's cut-out, the white light just remains on.

It hasn't been opened up, I've had it from new and it's worked perfectly until now.

I'm discussing the incident via Facebook Messenger at the moment. Would you recommend that I call in instead?

I have a ZP-100 which now powers up and plays music for a little while. It then cuts out, the white indicator light remains on but it becomes unresponsive in the Sonos controller, eventually disappearing. I've spoken to support and they recommended a factory reset which hasn't made any noticeable difference.

Mur,

Oh, that's bad. "Smoke" runs the world. If its smoke escapes, the device stops working. On the positive side, there is usually a charred component to draw one's attention, giving a broad hint about the fundamental problem.

There is no field service for SONOS. Continuing to use the unit will probably increase the damage.

Some users have successfully repaired their unit. Unfortunately, there is no documentation.
It did work until I tried change the speakers, when attempting to plug speakers in to unit something got fried inside the amp and a small cloud of smoke came from unit. Now unit powers up but does not power speakers? A component must have fried!
Mur,

Can you expand on what "blew up in my amp" means? Did the unit ever work? "No sound" can be caused by communication issues.

I bought zp100 connect amp, tried to hook up my speakers and something blew in my amp, it powers up now but cant get any sound from her now, anyone help me on this??

If it's been opened Sonos will not touch it. That sounds like a power supply issue, depending on your level of expertise/bravery you may be able to identify and replace a failed component.
I know this is an old thread, but thought I would give this a shot. I purchased a Play One, which had been opened by the previous user. After several months, it stopped working. No lights, nothing. This may be repairable through sonos. Is there a problem with it being opened? Also, is this a repair I may be able to do myself?

In general, the blinking white light means the system has power but has not successfully booted. At least on the ZP100 this can mean anything from the flash memory being bad, to the OS not being able to boot, to hardware issues on the dsp board. If the device gets an IP address you can try pinging it while rebooting(see http://forums.sonos.com/showpost.php?p=196297&postcount=11 ).

Hi,

I have a ZP90 which refuses to start up.
I observe a flashing white led light. It actually never stops flashing.
I've read on the FAQ that this means that the ZP90 is unable to start up.

Is this problem, or symptom, similar to the one in this thread?

I really would like to know, if it's similar then I could risk to open it and test my repair skills :-)

So my question to you, can you shed a light on the symptom encountered with your defect player? Was it also a continuous flashing white led?

Many thanks for your feedback, much appreciated!

I bought a used one on Amazon (becoming harder and harder to find these lately), and the mute button was dislodged somehow.

Opened, repositioned, fixed. All other functions are fine.

Guide was just what I needed to open it up.

May I firstly say a great thank you berrisford5, I salute your sharing of knowledge!
Without these instructions this task would not have happened for me.
Replaced the CA48 diode the T4A cylinder fuses for pennies though delivery of the fuses took a while.
All the best to anyone else who undertakes it, I had to use two small irons on the diode as not fully experienced or equipt in surface mount.

yes agreed. the inductor is fried (visibly 'open'). it's the yellow toroid next to the full wave bridge. it might have two windings. below the pcb is c16114 connected to it that looks a bit shabby - but might be ok (not sure yet). do you know the value of that capacitor? oh - this is a zp120. I had hoped to find a shorted smbj48 that this thread references but I cant locate that at all.. gotta get the meter and soldering iron out to learn more. tracing this schematic is going to be a pita.
survey_sez,

Something across an inductor is usually a snubber of some sort. If the snubber fries, this is a secondary issue. There is a big problem elsewhere. I would expect "hints", such as other charred components or odd shorted paths that you can easily find with an Ohmmeter. Follow the current source back from that burned snubber.

Does anyone recall the component designation number stamped on the PCB for this diode? I see something that looks fried across a large inductor that begins with a "C" - I assume that's not it..
I just tried the data sheet PDF and had no trouble. I'm using Firefox and the FOXIT PDF reader is linked as an addon. This file opened for view as any other PDF would open.

The Mediafire PDF in post #1, however, did try to stuff me -- I declined.
I found no such difficulty. Clicking 'Download' pops up the same dialog I always get with pdf's, offering to Open it in Acrobat or Save it to disk.
The link to your PDF is dodgy - I don't see why I must install a "Download Manager" that also tries to install other stuff - I do not trust this one iota. I tried to cancel the installation but it then proceeded to install and run the thing - this is unnecessary.

Downloading a PDF and viewing it requires nothing more than a standard browser.
