So, I am very new to using a rasberry pi, and I am trying to get it to boot up for the first time. I just used a formatted MicroCD Card, complete with NOOBS, and I am using an HDMI cable with a TV to get it set up. However, the TV is just saying that it there is no signal to receive from anything. The ACT (green) light is going solid for about a second and then blinking twice and going out. And the Power (red) light is solid for the entire time that I am trying to get it to boot up. Is there a step that I am missing, or is there something I have to do to get it set up to run on a TV?

    Which Pi? The TV needs to be connected BEFORE powering up the Pi. Make sure the SD Card is properly inserted. – Milliways Feb 28 '18 at 2:38
  • Is the TV set connected to the PI? Is the TV switched to the right input? – Uwe Plonus Feb 28 '18 at 8:45

As said by @Jaromanda X, and from elinux.org:

Green LED blinks in a specific pattern: ... 2 flashes: The SD Card cannot be read. Solution : Format card and flash Raspbian with Pi Installer from Terminal.

  • I'd like to suggest balenaEtcher as the right utility for flashing single cards. It's available for Win, Mac, and Linux, and it is careful not to overwrite things that aren't SD cards. – Bob Brown Oct 31 at 13:58
