Zeppelin speaker not working. Won’t turn on or show any power
I have a bowers and Wilkins zeppelin. The led doesn’t come on and it shows no indication of power or audio. The lead is fine as it works with another speaker. I have opened it and noticed some discolouration around one of the ceramic disk capacitors could this be the issue? Everything else looks fine.
This failure is well known, your main board had 5 class D power amp (one for each loudspeaker). In your case the boomer amplifier is in failure , you should change a Pmos Nmos SO8 and two resistors to recover function.
let’s post a picture of your main board (connectors opposite side) I’ll show you the parts involved in this failure
Mine has a pulsing red light when I plug it in, and a loud hum, then after 10 seconds a click and no more hum, red light flashes fast, manual says system fault, that’s not much help..
globally you have three type of “zeppelin” :
