Oh No! It's the Electrolytic Capacitor Plague! - Bowers & Wilkins Zeppelin Faulty PSU [Video 6]

Greetings everyone!
Today, we have a power supply from a fancy Bowers & Wilkins Zeppelin speaker that was brought in for repair. Customer wanted three electrolytic capacitors replaced on the secondary side of the power supply, but upon further testing, he was not expecting what else I found wrong with the power supply! I guess some things aren't made to last like they used to anymore.

Great video @Mr. ElectroniCET !
I have a Zeppelin too of which there is an issue with the WiFi module. I am sure that everything else is fine. Because I have another B&W with the same WiFi module. And if I swap the WiFi unit to the Zeppelin it works perfect.
Do you have experience with the WiFi module?
What would you advise?

[@Mr.ElectroniCET]

Unfortunately, I do not have any first-hand experience with the WiFi module in those units. It could be just a faulty WiFi module, or there might be a failure with the power going to it. Hope this helps and thanks for watching!

Hi. Never startup a switch mode power supply “SMPS” without no load. Thats why you supply voltahe is dropping and rising. Sometimes it Will rise the voltahe so High that it Will damage it self if you test it with no load on main rail.
