I recently purchased a Raspberry Pi 4 B 4GB model and it came in today, so I plugged in the class 10 micro SD card that came preloaded with NOOBS and nothing showed up, I then tried editing the config.txt and tried to force HDMI, nothing. So I formatted the SD card and tried just installing Rasbian Lite, also didn't work. I then tried installing Rasbian Desktop once again didn't work. I have so far tried two different monitors and one HDTV all with different resolutions. The latest thing I tried was following this video tutorial https://www.youtube.com/watch?v=JYrGoLbiyj8 however when I plug the Pi in after extracting everything and inserting the SD card my LEDs are not flashing. Do I have a dead board if not how do I fix this? If I do have a dead board how do I get a replacement?
Edit: Turns out I was using a fan and inserting it into the wrong GPIO pins, if anyone runs into this issue in the future try unplugging the fan and then booting into your OS.
