This is the first time I've tried to use a raspberry pi, I bought a CannaKit that came preloaded with NOOBS. When I attempt to boot with the HDMI my screen says no signal, the HDMI output is correct, I've verfifyed that the cord works. When I search online forms want me to change a config file from the SD card, I've searched all the folders and there is no config file; or they tell you type something in, i have no video output so I cant see if i'm typing or anything. Does anyone have a solution? Thanks in advance.
Given the information in the comments (the red LED staying on solid) means that the SD card does not have a valid boot partition (ie. Operating System) on it.
A solid red LED indicates that the Pi is ok, but it can't start up.
You need to re-flash the SD card, put it back into the Pi, and power it up.
Installation instructions can be found here for both NOOBS and Raspian OS builds. You'll need to read through all of the information, including the link that directs you to the Operating System you're running on your computer.
