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.

Thanks!

Same problem too. Asked B&W who just said it would cost £80 to fix and you have to expect such faults in electrical equipment : but this is the second time the power unit has malfunctioned on this Zeppelin in 8 years!

Hello… My Zep. Will go on and work some of the time, and then just shuts off and won’t power up. The red power light will be blank. Then the next day…on again, works…and off again. Is there a recommended service center local in Los Angeles or anywhere trusting to ship to? Please help. I want to keep the unit I love it when its working!

Hi

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

regards

@iso14000 is this directed toward the problem that Dja Wong is describing?

I have a failed zeppelin also.

That capacitor doesn't look too bad.

On mine, the onboard fuse is blown, and at least 3 of the rectifier diodes.

If you have a multimeter check the diodes for short circuit.

There is a bank of for of them on one edge of the board, and another on un the underside of the board covered in heat paste.

Still workling through what else might have gone...

SOP for all repairs: do we have power. My Air has just done the same as these others. My original Zeppelin is just fine.

Yes this link to a French language site is detailed.

I have been given one of these to repair and am contemplating replacement of the entire SMPS70 board, if only because someone has put a wire link across the blown mains fuse…. not very subtle.

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..

I too have this issue, anyone been able to resolve this ?

完成的

Yes, just one capacitor 2200uF /16V (high freq. type I think) was enough. It was bold. Beter to make thye new one 2200uF/25V is also possible.

I've exactly the same problem. Has anyone fixed this yet?

globally you have three type of “zeppelin” :

-the first one with a power supply from Abletec : you can reach this forum to have schematics and how to fix it https://www.abcelectronique.com/forum/sh...

-the zeppelin AND BW A7 share the same electronics : you can read this forum to get infos and schematics

https://www.abcelectronique.com/forum/sh...

don’t hesitate to post in english , you ‘ll receive info .
