In the mean time I decided to probe around and have a small concern. Listen to m0untainman, he knows what he is talking about. So I am wondering if that is what may be blowing that? The pulse diagram of Fig. SPS Idrain 1 2 Figure datqsheet Next the function of the PFC charge pump circuit is explained in detail using the pulse diagram of Fig.

Anyways, I really hope this helps others. The PWM is warm so its the likeliest suspect at this stage. They 5m026r5 nothing using a 60W bulb. The amp has no power. I tried a watt bulb and it let too much power through, so the bad components would get raging hot quickly. I had to get creative and solder wire patches to get it through the hole so I could solder the leads back Between the control voltage Vcon and. Previous 1 1 of If there is no blinking lights, then you prob have a blown fuse and no bias converter.


I would unsolder that PWM and watch the bulb go out! I just found a site with some pretty good directions on building the dim bulb tester: Figure datasheft a detailed block diagram. The best resource that I found for fixing and diagnosing power supplied is here: We CAN fix these things and with a great community like we have here, we can keep these things running. That sent me on a Youtube and reading spree that gave me the tools and confidence to diagnose and fix the problems.

I would like to share a couple of items that may help others Total opportunity cost I almost tossed it If you remove the PWM, clean it and use the arctic silver 5 thermal paste. I’m guessing that will take a breadboard. I’ll post when I get them and try it out.

I’m guessing the short is somewhere in that area. IMHO, that was invaluable.

There it was in all its glory and works! LOL JK So the inductor in the upper left of dagasheet picture is the common mode inductor that is in series with the 28V supply. Previous 1 2 If so smokin’ deal! Thetypically 12 dB. From the circuit diagram above, it indicates that the grounding for the.

We will get good at this some day, maybe Sonos will hire us?? Looks like the replacement is a KA5MR. Dataasheet site and doc really walks through the different sides of a power supply and what to look for.

I would love to hear if anyone has any hacks or ways to deal with such a problem. Also, the dim bulb was brilliant.

He has a nice chapter on a dim bulb tester. Share Tweet Share 1 Share whatsapp. I have no idea what kind of solder datasehet Sonos uses, but it is insane. Based on the schematic, this part looks blown to me.

datasjeet I’m really hoping this is the bad component since my bulb is full dim after the caps charges and this PWM is removed.

One of my amp ICs was a short.
