Hi, Im using a alt. power supply. Connected a Charger with: Output USB-A: 5V/4.5A, 9V/2A, 12V/1.5A to my Homey. Something happend, it whent in to just showing a blue light and its not responding to the app. I have tryed to reset it by turning it up side down, but nothing happends. Did i overload it…

Yes, if the LED ring is showing a color you would think it still gets power. But if you can’t get it in recovery mode I don’t know of any other way to fix it.

That happened to my brother in low … was not able to find the broken component yet, a pity there isn’t anyone having some experience with fixing it. Re upside down - keep it like that even for longer time - eg. 2 min. - if nothing will happen, your Homey is dead ;-(

[image] Sharkys: was not able to find the broken component yet, a pity there isn’t anyone having some experience with fixing it. Looking at the PCB there’s a fuse in the power supply area and also what looks to be a switching power supply IC. I would start checking those.

Robert thank you - do you mean those two parts? In my case, I checked them, but seems to be somewhere deeper as I can measure 3.3V on Zigbee/ZWave and 5V on LED, if I’m not mistaken… also 5V on sound amplifier But LED are dead, HP19 takes only 300mA, naturally it do not respond to the reset…I have…

Yes, those are the ones. It’s quite possible that this is a 3.3V power supply (which could have survived a higher voltage) but that other parts of Homey are directly powered by the USB power supply and got blown up. Worse case, the SoM module is dead :grimacing:

It’s a carrier board in itself, see this page for the single core/512MB module and this page for the dual core/1GB module. You can see it has three connectors that I assume connect to the main Homey PCB.

[image] robertklep: carrier board in itself Maybe I did not express well myself, I meant something like this for CM4 : https://jfrog.com/connect/post/the-ultimate-raspberry-pi-compute-module-carrier-board-comparison/ … (basically for some trivial diagnostic, connect via USB and see if it wo…

Like this? HUMMINGBOARD-I1 BASE SOLIDRUN - Single-board computer | RAM: 512MB; i.MX6 Solo; 85x56mm; 5VDC; DDR3; SR-HB01B00000 | TME - Electronic components (WFS) (coincidently, it looks a lot like the Raspberry Pi 1 :sweat_smile:)

Soo the same thing happened to me, cracking noises, led flashes red, disconnected power only a single blue light comes on. Opened homey, and i find a fried component, problem is I don’t know what it is. Anyone knows what this is by any [1000009888] [1000009887] chance? Thank you
