I did my own repairs and lost ___ or found this broken part! What is it?
If you are attempting your own repairs and need help identifying a particular part that is damaged / lost, feel free to ask!
The most commonly lost part is pictured below. If you are having issues replacing it, you can try the pictured workaround with trace wires and a physically larger capacitor. You NEED it for the HomePod to power on! It is a 0.1uF Size 0402 Capacitor. Anything rated 10v or better will work..
