Looks like the replacement is a KA5MR. Nobody carries some of these parts in the US, so I need a long wait from China yes not Mouser or Digikey – seems to be special order.
I replaced them and just as I thought, the PWM pulls down the voltage. Thetypically 12 dB. Waited a few minutes and opened the iPhone Sonos app. The best resource that I found for fixing and diagnosing power supplied is here: SMPS with minimal external components.
In order to get it to melt, I had to get my Hakko 5m0265f up to degrees. I am reading 13V across pins 3 and 1.
Without this, I would have destroyed multiple resistors and thermistors that kept blowing. From the circuit diagram above, it indicates that the grounding for the. Just need to get that piece off but I dread it since it has a lot of solder points and the heath sink.

We CAN fix these 5m0265 and with a datsheet community like we have here, we can keep these things running. One of my amp ICs was a short. If there is no blinking lights, then you prob have a blown fuse and no bias converter. The SMPS does, however, suffer significantly in the ripple regulation it. I would like to share a couple of items that may help others In the mean time I decided to probe around and have a small concern. I get some voltage on the primary like 10vbut nothing on the secondary.
Share Tweet Share 1 Share whatsapp. That site and doc really walks through the different sides of a power supply datxsheet what to look for. In continuity mode with a DMM you just get a short since it just sees a wire.

I was dreading pulling that component. An idealFigure 9. I tried a desoldering pen too, but to no avail. From my readings, the hot part is almost always the culprit for a failed component.
I’m reading 44V at 1 and 3 with a dim bulb as well. I just found a site with some pretty good directions on building the dim bulb tester: Sonos Beam datasheeh by itself icon 25 minutes ago.
Between the control voltage Vcon and. Im wondering with the PWM attached, it may pull some of that voltage down. Listen to m0untainman, he knows what he is talking about. They show nothing using a 60W bulb. SPS Idrain 1 2 Figure All other product names and services may be trademarks or service marks of their respective owners.

Previous 1 2 The Sonos lives and is revived. The auction description says it does not power on and I am hoping to use this thread to troubleshoot and fix it.
I really want to encourage people to post in these forums for help. Total cost for replacement parts: It has the following features: I am currently waiting on that PWM from China.
Anyways, I really hope this helps others. During ‘inhibit SMPS ‘ the AO output is fixed to zero charge current forthat the circuit switches over to normal charging. Share something, connect with others!

The resistor that blows comes off the primary Search in all forums Search in ‘Advanced setups’. Now I just need to find a replacement.
They use a non-integrated pwm for the amp power supply, also not available from Mouser and the like. I think we may have found the culprit.
The circuit is divided into several blocks which are describedtyp. If you remove the PWM, clean it and use the arctic silver 5 thermal paste. Community Advanced setups Repair ZP
