Zeppelin Air Intermittent Power Repair

[@andymartin86]

Hi, I have an issue at the moment with a fast red flashing light. I had changed all the PSU caps last year which fixed the original issue. Now ESR tested all the motherboard caps and found all the SMD caps to be low capacitance and high ESR except for the large 470uF. Got everything on order for tomorrow hopefully this sorts it.

Thanks for the video. You should better use an anti static mat and ideally a writs strap to ground. That acrylic blanket is soft and nice but will ESD zap those delicate CMOS DSPs.

Dont chat shit fam

@@MrReeceyburger123 Well , it seems you have similar respect for people's opinion as you show for CMOS IC's. I am over 60. Fourty years working for one of the manufacturers in that board tells me that you may run ocasionally into ESD trouble. Then of course you can blame the manufacturer or keep changing parts blindly until you spot the failures or determine 'it cannot be repaired'. That may work, or not. Good luck with your IKEA blanket but still perhaps you may want to reconsider a cheap anti static mat and a wrist strap. Oh... and sharper multimeter probes will help you better than those huge bananas on minute 15. 😉

I’ve been repairing electronics for nearly 20 years and never once used an ESD mat or strap. Never ever killed anything and this extends from industrial PC motherboards to large 3 phase inverters.

[@josevicentegaspar]

@@andymartin86 Well... what can I say other than how do you actually know you never killed anything? . I do not seek polemic, just highlight that 'never had a problem' may translate better as 'never knew if I caused an ESD problem'. You would need to decap the device and use an electronic microscope to actully see the ESD zap trace. As a user you will never know what happened. ESD'ing an IC does not make any sound, smoke or noise.

I just repaired the blown mosfet problem on the PSU and the speaker worked fine all day thursday. Cam to try it Friday morning and all I get is a red light and a low hum from the woofer. Very annoying and I expect better from B&W

Hi! I replaced all the capacitors in the power supply except the high voltage ones. When I turn it on, it starts up and plays music, but if I unplug it after 10-15 mins and plug to socket it back in, it starts slow flashing red for 30 minutes and then starts flashing quickly. If I unplug it from the socket at night, then in the morning it turns on as if nothing had happened until the next disconnection from the socket. Could these capacitors on main board be to blame for this behavior?

Well spotted we all make mistakes mate don’t feel bad 😬

[@MrReeceyburger123]

I still need to have another go at that board, maybe it might work haha

[@martjackson7942]

What output should the power supply be giving the main board, cheers

[@trungbiscuits899]

is the failure common among these Zeppelin (2nd gen black back)? I saw a couple of them locally and they're quite pricey and not sure if they're worth the risk :(

[@goranulardzic2801]

Can you do modification on that speaker to be powered by external battery?

Hello @mrreeceyburger i have the same model of zeppelin. It was always working good. But 2 month ago I shifted my flat and I packed it for 2 weeks in his package back. So it was without electricity this period. When I unpacked it and want to switch it on the power was dead. No Funktion at all. Any idea which part it could be and any change to get that or repair it? B@w said no Chance. The don’t have parts anymore. So sad. Bc was a nice sounding speaker.

Persevere. The dealer will spin you this story. Try find a decent recommended backyard “techie”

I used to have more confidence in tantalum capacitors.

This product is one of the worst I have ever used. Both times I bought this product and it failed on me. I thought it was just bad luck the first time I bought it but the 2nd one also failed. Not even sure where to take it for repair. Mine just have a solid white light and does nothing. No response to the remote also.

[@MrReeceyburger123]

The air is useless, do your self a favour and buy the generation 1 zeppelin and fix the smps.

[@jamesroeber]

HI, any chance I can contact you? I have a couple of zep speakers I am trying to repair. I am sure you get loads of these messages....jj
