For anyone reading along here, please note that this is a very bad idea for a number of reasons, the most important being:
1: It’s dangerous, potentially resulting in serious injury or death. Please do not open the speakers, as they can still carry a charge despite being powered off / unplugged.
2: You are breaking your warranty: Sonos Terms of Sale
3: Sonos can’t help you fix it.
I had destroyed my sonos play 5 gen 2. I made a mistake which caused power supply of 400V.
Then I found the very usefull youtube video explaining met how to repair.
The 3.15 A fuse and the varistor where dead. After replacing them the speaker was able to power on.
But the sound is not well. It produces almost no mid and high tones. I have disconnected the three base speakers and found it does give a little bit of mid and high tones. All three speakers are working. But not at normal levels.
Does anyone have a next step for me? Or can I buy the complete repaired board somewere?
