I am assuming,you have all the power cables connected. Also some more info,are the other hardware running?

[Rustys]

Does the unit seem to be powering on correctly?
You are connecting to the Display card?
Do the fans come on?
Can you tell if the water cooler is circulating the fluid or not?
Does anything get displayed on the screen besides no video input?
Do you hear the beep codes and if so what are they?
Are there any lights on the motherboard and if so what are they?
You did connect the USB ports to the motherboard properly?
If you rebuild the system outside of the case on a non conductive (cardboard) does it work properly?
RAM is in the proper slots?
Others may have more to ask.

Which one is lit up

CPU is red on motherboard

You did not have to force the CPU in and it is secure?
Do you know which version of BIOS in installed?
You did use about a pea size amount of thermal paste?
Remove all of the plastic coverings between the CPU and the Cooler?

@Bruce and @phillpower2 may have more ideas and or suggestions.

Got the following warning when I entered the above info into a PCPartpicker list here

Warning!Some AMD B450 chipset motherboards may need a BIOS update prior to using Matisse CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions.
