Question Asus Prime B550-Prime Motherboard -Fans and lights turn on, but no display or Boot lights

[Mad_Kat]

Hello everyone - I'm in the process of a PC build using the below parts;

Asus Prime B550-Prime Motherboard
AMD Ryzen 5 5600X CPU
AMD Radeon RX 6700XT
DDR4 3200 8G x 2 (Temporary)
Corsair 550W PS (Temporary)

When turning on the power supply to the PC, this motherboard lights up cosmetically (a white/yellow strip in the back). When actually turning it on with the power button on the case, all of the fans and RAM lights turn on - but there's no display on the monitor. And more importantly, the Q-LED lights on the Mobo (CPU, DRAM, VGA) do not turn on at all.

I've tried a few different things to remedy the display - swapping out cords, rearranging the RAM, unplugging the gpu to use the cpu's integrated graphics instead, reseating the cpu - but nothing has worked. Due to the Q-LED lights not turning on at all, I have to assume this is a Motherboard issue. I tried looking at the mobo's manual, but there's nothing listed for the event of the Q-LEDs showing no lights at all, only for certain light frequencies/patterns. Thoughts?

I've discovered the issue - the CPU power cable was not seated properly, PC now boots normally and display and Q-LED indicators are on
