Chosen Solution
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! Update (01/07/2018)
Could this be the issue?
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
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…
Hi You should check this : https://www.abcelectronique.com/forum/sh…
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” : -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 . best regards from iso14000
