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 , just find out today ! Appreciate someone gives a solution for it

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?

Hello, I think I got you, I have a zeppelin with that same issue, I don’t think I can upload pictures here but the board has one burned ZXMN 6A11 chip,, do I need to replace that one but also the one behind? And which resistors?

完成的

@iso14000 could you please tell me what kind of diode I need to buy to fix this, mine is in short circuit, diode behind the resistor under the Pmos Nmos transistor

完成的

you should have a look on the french forum , just type "abcelectronique" and "zeppelin" to reach the thread. I'll touch you at this place

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...

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.

完成的

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

完成的

Does anyone know which capacitor Marlon Van Vuuren is referring to above? is it on the power supply or DSP?

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 .

Hello my name is François. I have a Zeppelin (last model) since july 2022. I have a lot of problems with it. It 's out of order now (since yesterday).

No bluetooth connection, no reset, no recognize on my smartphone, Nothing. No light on the different buttons. Just a little sound, a kind of click then clack a few seconds later, as it tries to connect but nothing. Reset doesn't work. I taked off the application Music B&W, I shouldn't have done it. I can not restore it again. No connect, no recognize.

Could you help me?

Thanks a lot (may be I'm going to put back on the store)

I had the same problem on my older Zeppelin Version; No more Power :-(

The power supply board had been repaired by a Sound Electronic Technician for $200.

Hello François!

I have a same Zeppelin (2022) like yours and I had a same problem like with yours:

"No light on the different buttons. Just a little sound, a kind of click then clack a few seconds later, as it tries to connect but nothing. Reset doesn't work."

What has happened with your Zeppelin? Is there working or still not?

Thanks: Bill
