The POST LED's can and will ONLY work if the mem and or cpu is working.

Think. It takes both for a board to display on the leds.

Time to pull the cpu and inspect pins. That checks out then it's on to testing the mem .

I would tend to agree that it could be another component, but if it was something else, I would expect that I would at least the the case or cpu fans to spin up, and some kind of error code. the board is currently outside of the case on a piece of card board.

He should still be seeing something on the led though, don't you think Daytonyb?

Unless the motherboard is shorting on the case or something. Tried it out of the case on a piece of cardboard?

if you had the same issue before with the same type of board
logic dictates either a cpu or ram problem

its usually the power connectors with the TR non boot issue but if your confident you have checked that ..............

Thank you for the quick reply. I have triple checked that the CPU power cables are in the correct positions. The clip on the 4 pin is facing in toward the ram, and the 8 pin clip is facing to the top of the motherboard.

As long as all the power connectors are attached in the correct orientation (one of the 12v 4 pins are rotated 90 degrees compared to the others) and there's nothing wrong with the PSU then you should be getting something on the post LEDs. You say you've tried another PSU and motherboard so unless it is an unlikely coincidence that you had 2 faulty motherboards in a row, then it MUST be the power connectors incorrectly installed. Check where the clips are on each connector and make sure they match the cables because, as I said, one of the 4 pins is different to the rest (and most other motherboards too).

Folks, I am sorry to bring this up again. I am havingtrouble with an Asrock Fatal1ty x399 not powering on. I know this has been discussedon this forum before; I have been unable to find many posts with an actualsolution.
Specs:
AMD threadripper 1950x
Asrock Fatal1ty x399 BIOS ver. 1.05
Corsair rm1000 PSU
Gskill ripjaw v 3200 64gb
Enermax liquatech 360
Asus armor OC 1080
Samsung 960 pro m.2 ssd
 
I am having similar issues to other members, where when thepower supply is turned on the LED lighting under the heat spreader behind thepcie slots illuminates; when the power button is pressed nothing happens. TheDr. Debug does not display any error codes, nor do the case fans or psu powerup. I have removed the motherboard from the case and having it sitting on thebox it shipped with. I am using only one stick of the ram; I have tested itwith and without the graphics card. I have insured the 8 pin and 4 CPU power connectorsare connected properly on the PSU side as well as the motherboard side, I haveused a volt meter to check the pins on the 24 pin as well as both CPU powercables, they both check out fine. I have attempted to use another power supplywith the same results. I have shorted the 24 pin power while it is plugged intothe motherboard to start the power supply, when this is done all of the peripheralsthat are plugged into the motherboard start as normal; however the board neverPOSTs, nor does the Dr. debug display any error codes.
 
I should also note that this is the second motherboard that hasdone this. I originally bought the same motherboard and it exhibited the samesymptoms, I contacted Asrock support for assistants. After some time troubleshooting with them, they determined it was a motherboard issue and replacedthat motherboard with this one. Since the new one is also exhibiting the samesymptoms I do not believe that this is an issue with the motherboard.   
 
Any help would be much appreciated.
