Question No signal

[Kahikatea]

Components I had the problem with
-Z790 Asrock/Z690 Asrock Phantom itx (with biosflash for the newest update)
-NZXT 750w/Corsair SF750
-MSI 1070/Gigabyte 4070
-2 Corsair 32GB
-I5-13600kf

I tried both GPUs on multiple ports with 3 cable, and I know the hdmi works for sure.
I tried all ram slots ins every configuration possible.
Red indicator lights go on while booting but quickly off again( I think that is how it is supposed to be).
All fans and lights are on and visually there is no problem. I think I can even go into windows.
The signal goes lost along the way I guess and I would really need help identifying which one.

This may be a silly basic question, but are you certain you are plugging the HDMI / DP cables into the back of the video cards and not the motherboard? Also, what monitor are you using?

So you've tried the 13600kf with two different motherboards, two power supplies and two GPUs, and still can't get it to display?

At this point, I'd probably try and borrow an LGA1700 CPU preferably with iGPU from somewhere and try that. If you can get a display on the iGPU and then from the GPU, you might just have a bad CPU.
