Hello sonos , currently I have the an issue of a high pitch noise coming from my Sonos playbar , from research it seems to be a transformer issue which I’m trying my hardest to get fixed.
I have found that these Switching Power Supply Inverter Converter Ferrite Core Custom Transformers can be found on aliexpress for about £50 for a pack of 5.
sonos have seemed to be reluctant to fix these issues of high Pitch noise from the transformers and as it seems to be that there was a bad batch of switching power transformers that some how worked there way into supply chain during the manufacturing of these playbars. personally I find it quite annoying that you haven’t offered a replacement power supply board for a fixed price etc for users to replace them or something along those lines.
I have been in contact with countless repair shops and companies to fix this issue I have currently.
I am probably going to try and fix it myself but I will be calling Sonos soon to trying and see if there is anything they will do.
will sonos help me with this repair and fix this because I’m very disappointed in such a amazing brand like this doesn’t have any information on how to fix this, diagrams on the power supply or anything. I have searched for replacement power supply’s to fit it myself but can’t find any in Europe, I have search for these issues online and have only found these community comments, reply’s and conversions.
