When I power up my Raspberry Pi 3, the red LED lights up and stays red until I unplug it. The green LED always stays off no matter what: - I tried 3 different 2A chargers - I tried 2 different SD cards (each formatted by the SD Formatter tool), both with NOOBS and Raspbian images copied on it (and also without any SD card)

Devices I try to plug on the Pi never get powered (and neither does the network)

Any idea on how to diagnose that Pi to figure out how to fix it?

  • Who are the chargers and SD cards made by? – Darth Vader Apr 3 '16 at 17:43
  • And the HDMI out doesn't display anything? – mlhDev Apr 4 '16 at 2:30
  • Do you have a multimeter? If so, check the voltages on the board when it's powered and make sure that it reads ~4.80-5.10 volts or so. The micro-SD slot is a good ground connection. Make sure you don't short out paths and pins with the other probe. – jDo Apr 4 '16 at 2:38
  • SD Cards were Kingston/Samsung ones, HDMI was always "silent" and no multimeter sadly. After contacting the retailer, they're exchanging it, so at least I'll know with a new Pi if it was anything I did or just bad luck to get a non-functional card. – Charles P. Apr 5 '16 at 15:41
  • After switching the Pi for a new one it turns out that I just had bad luck with my first one and everything was fine on the new one the way I was doing it – Charles P. Apr 19 '16 at 17:39
