Monitor has power but the screen stays black

The power light on my monitor is on and it shows the brand logo when I switch it on, then black. PC fans are running and the keyboard lights up. Already tried a different HDMI cable. What should I check next?

Is there a graphics card in the PC? If so, make sure the cable is in the ports on the card itself, lower down at the back, not the ones on the motherboard near the USB ports. With a card fitted the motherboard outputs usually do nothing, and that's the most common cause of exactly this. If it's already in the right place, open the monitor's menu and set the input manually to the HDMI port you're using rather than auto. After that I'd try DisplayPort if both ends have it, and a different monitor or TV to see whether it's the screen or the PC.
