If your OG HomePod dies because a component failed, you might check this site. The guy does HomePod repair work and will sell replacement components if you want to do the work yourself. Evidently some of the common failure points are replaceable.

I've never had this happen to me but I hear this more and more from people. I plan on getting these new ones so I hope it's not a recurring theme with these.

These have the updated processors and related circuity from the HomePod mini. The minis don't seem to have the component failures that the OG HPs had.

Yeah mine one died by itself (one day was working, next just didn't turn on anymore)
