ZP80 cuts out when grouped with Sonos 1’s icon 1 hour ago. The circuit is divided into several blocksan SMPS circuit directly. To adapt the SMPS switching frequency in the synchronized mode. In order to get it to melt, I had to get my Hakko iron up to degrees.

The Sonos lives and is revived. Shut off the power and put the wifi cards back in.

Is there an internal fuse for this unit? There is no go-to source. SMPS with minimal external components. That site and doc really walks through the different sides of a power supply and what to look for. I just got notice the unit shipped and will be here next week.

Then go looking for trouble. This helped me trace the hot part. On your first one getting the chassis apart is an adventure. Bob is your Uncle!

Playback stops all the time!! I had to get creative and solder wire patches to get it through the hole so I could solder darasheet leads back That sent me on a Youtube and reading spree that gave me the tools and confidence to diagnose and fix the problems.

I just found a site with some pretty good directions on building the dim bulb tester: The dim light is indeed bright. Now I just need to find a replacement. Keep in mind it was DMM tested on board and I have not removed it.

I think I have detected a short on it or something connected to it Anyways, I really hope this helps others. From the circuit diagram above, it indicates that the grounding for the. It is critical for testing any sort of power supply to keep you from blowing more components. I am pretty good with soldering and have already checked out some possible part replacements on eBay.

So I am wondering if that is what may be blowing that? I will share a troubleshooting slide on the 28V supply when I get it working reliably. Setup for 65 square meters living room icon 1 hour ago. That is datasheet the dim bulb installed so it is probably a little bit higher.

I think we may have found the culprit. The PWM datashet not switching therefore no secondary voltages will show up. IMHO, that was invaluable. It will distribute the heat much better. The resistor that blows comes off the primary LED Drive smps circuit diagram Abstract: Im wondering with the PWM attached, it may pull some of that voltage down. Getting it off components was a chore.

The pulse diagram of Fig. I put together a little procedure for removing the bias converter PWM.

The auction description says it does not power on and I am hoping to use this thread to troubleshoot and fix it. From my readings, the hot part is almost always the culprit for a failed component. Also, the dim bulb was brilliant.

Not sure how to test a PWM Start a conversation, ask a question or share your ideas. You can always get stuff from China via eBay for example. Could that be that the inductor has a short? Search in all forums Search in ‘Advanced setups’. I’m reading 44V at 1 and 3 with a dim bulb as well.

If so smokin’ deal!
