Amazon Echo Studio Netzteilplatine tauschen

I contacted the Amazon regarding the matter, and spare parts are not available. The solution from their side was a credit towards a new device with a discount. Spare parts are not available.

The power source is custom built just for this implementation and there is nothing similar on the market as far I have found.

bonjour je rencontre le meme probleme avec mon Echo Studioet impossible de trouver la carte d'alimentation.

I have exactly the same problem. Blows the fuse everytime I plug it in.

Bought November 2022 and broke 12 months later, the morning after the warranty ran out.

i found a shorted MOS FET (20N65) , one burned big resistor on the top side and two exploded SMD resitors on the bottom side

You don't neet 30VDC power supply as original used it need only ca. 0.3A by 30VDC from the power supply. I replease the old one supply for a new one I suggest you use/buy EPS-45S-24 from MEAN WELL 24VDC on output is just fine and work properly

Didn't know why my Echo Studio, which had been working fine for over a year, just suddenly wouldn't work at all. It sat in the garage, unplugged for over a month until I found this video today, while looking for a place to send it for repair. Disappointed that parts aren't even available, at all, I about gave up. Then when I went to check which "version" of Studio I had, I unplugged the other one to use that power cord. I'll be danged! It came on and worked fine. In fact better than the other on. That one will not "remember" the set volume the next time it's turned on; same as one of my Alexa's. So, I'm happy I don't have to spend $200 to get another one. Good work, there. Now if I can get my Sub to play the same song as the Alexa's, that's my next challenge.

same deal here, blows the mains whenever the PSU is plugged in (even w/o any load attached)
peeled off some of that silicone goo and revealed a popped THT capacitor

you can check your cap easily from the bottom side...
Have the "PRIMARY" text upright
it sits just right of the central rubber foot (touching the Drain pin of the MosFET Thomas was mentioning) and moves north to R131
sharing the copper Trace with the same MosFETs Source pin)
if you find a short there you are most likely to be having that same cap blown.

That unfortunately means you have to desolder at least one of the large caps (the inner one) to be able to carefully remove that goo
and finally replace that cap... I can't tell what value cap will be needed my first guess is "100pf 1kV"

Plugged, nothing happens except for getting hotter on top. No signs of burnings or exploded things in power supply unit witch, however, has been placed in the bottom.. Can't say i'm 100% sure because of the amount of glue/whatever on it. Think I should test the power unit first and then go ahead and tear dowm the hole thing to check the light board on top. So, how to test it? I don't know where to put power and where to put the tester/multimeter. It will not work again, I know; let's use theese 200 € to learn something. Thanks to everybody, except for amazon.

If you have problem with power supply board you can make your own, but you have to put it outside like an adapter, it needs 30v DC at 2 amps, you can make easily by connecting 2 adaters of 12v each in series, total = 24v, it worked well forme.

Could someone please give me the resistance value in ohms or the part number for resistors R131 and R118? Thank you.
