Sonos ZP100 dismantle and possible repair guide.

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.

    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..

    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.

    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.

    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.

    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.

    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!

    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 ).

    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?

    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.
