Hi, EVGA I just notice today my LED that tells posting and Temp on the motherboard is not working properly. Meaning I have LED telling temp of my cpu but LED #3 is not visible to see number well.  
            1   2   3  4 
           [0][0][3][2] CPU temp on led
                                               faded on number 3. Best I can show since I can't take picture because led's so bright not even with flash disabled works to take picture.
In POST LED 1,2  I don't see any lights coming up. Mind you I am not having any issues were motherboard is posting anything. Motherboard seems work fine and in Gaming not having any problems. the only problem I am having in POST LED # 3 not visible or bright enough to see well. Also there has not been any power outages in my area. Everything else in PC working fine. Finally got cell phone can take really HD videos so here belated proof LOL just too long post. This is what MB  now shows. 05/03/2022

So not me alone. I do wonder since they sold out the z490 mobo's. Well I guess I can wait is five yrs warranty. till they ressupply. but like see my temps.

If you are under warranty contact EVGA tech support. 

Same here, my first number in temperature LED suddenly became dim, I can now only see second number. Never had LED die on me like this.

So I’m having the same problem except my mobo is the z590 FTW. First number is dim and doesn’t properly display cpu temp. Any update on y’all’s issue? Thanks.

I have owned all of these motherboards from EVGA.
 
Evga X299 DARK.
Evga Z490 DARK KINGPIN.
Evga Z590 DARK.
 
Everyone has had debug LED problems. The X299 Dark debug LED’s just fell off.. The Z490 Dark Kingpin Debug LED didn’t work properly. (Not legible, or unable to read)
And now, my brand new Z590 Dark motherboard that costed $644 dollars with taxes from Evga now has LED debug failure. 


 
what a joke! And what sucks about it all is that, it’s just a horrible inconvenience. Do I want to tear apart my entire test bench, custom loop, just to send Evga my $650 dollar motherboard, so I can have functioning debug LED’s again?? Absolutely not.. And even if I did. I’m just gonna get a new motherboard and the debug LED’s will slowly deteriorate.. 
 
 
The question is not, “Is your debug failing” every Evga motherboard I have owned is failing.
 
 
”The question is” “Why Cant EVGA build a properly functioning debug LED?”
 
it should work.. This is a brand new $650 dollar motherboard. 


 
This is a photo of my Z590 Dark. I don’t care enough to send it in for a replacement, because I already know the replacement will fail.. My X299 dark failed, Z490 Dark KP failed, and now the Z590 Dark.
 
 
All I can say is, deal with it like I do..At least 1 number works. Will your CPU temps and voltages display correctly? LOL, good luck With that!!
 
 

Got a same problem on my Dark KP.
It's second board i get from evga, after first was DOA.

Add me to the que. My Z490 Dark KPe is unreadable. I highly doubt the even have Z490 Dark KPe stock just sitting around.

Yes unfortunately your MB have same issue glad you posted here hope rest is working fine. Time to get support on the line.

I recently purchased a brand new x570 dark motherboard and my post led is going out too after only running it for not even 3 months and I was thinking the same thing should I send it in just for them to either replace with another post code led that is just going to burn out in another 3 months just like the first on but I was wondering if anyone knew the part number for the actual post code led thats on the x570 dark motherboard that way I could see the pin layout on it so I could just replace it with a better one that wont burn out 
 

 
I'm probably going to send it in just really don't want to disassemble my custom loop because everything is hardline but that link I posted is the post code led that I think that they're using on my motherboard and probably the same ones that they are using on the other dark motherboards that have the same issue and if you look at the spec sheet it states to use them within a year which is odd I would assume that as long as they were stored in regular temperatures that they would be fine for a longer amount of time because people usually don't just use motherboards for a year but who knows I'm a welder not a computer hardware engineer haha and I'm too new to post a link apparently so its the TOD-2281 from oasistek you'll have to look it up from there 

my x570 ftw has Post LED dimming issues too. At first one segment on the second digit would be dim every once in a while. After having that for a few weeks now the first digit dims too. I really dont want to have to RMA my board over this tough since it runs fine otherwise. Probably going to keep it as is unless something else messes up. I had this board a year and a half before this ever started
