Question Motherboard repair help pls

[KingVegeta]

CPU: Ryzen 5600
CPU cooler: AMD
Motherboard: Asus
Ram: G.Skill Trident Z Neo 2x16
SSD/HDD: SK Hynix 256GB m.2
GPU: Radeon 5500
PSU: EVGA 600 watt
Chassis:
OS: windows 10
Monitor: Gigabyte M270
I picked up an used Asus Prime x570 pro; thinking how hard could it be too fix. I have even more respect for repair techs.

The board turns on but doesn't post. I have tried clearing the cmos, trying different components, and unfortunately this board doesn't have a way to flash the bios without posting first. I used a power supply tester to make sure that was good to go. And other stuff work with this gens am4.

I tried using a post card. The TL631, but all that told me was power is good and a solid red light on RST.

THE board also looks to be in good shape. I cleaned it up a bit with isopropyl and a q tip.

Welcome to the forums, newcomer!

You might want to start by prefacing your build with the following;
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model.

You might want to grab a CH341A BIOS programming toolkit, reflash the BIOS with the latest version, then clear the CMOS and see if that revives the board.

I tried using a post card.
A POST speaker would be helpful in this scenario.

Thank you, and I will update the post. I think I have that tool. Got it yesterday. Do you know a good video of website I can learn how to use it?

solid red light on RST.

cmos jumper still shorted or cmos battery short as reset line is held low.

Thank you. Ok I understand some of that. Some how cmos/cmos battery is shorted. I can take a look in those area with a microscope and see if something is bridged. What i don't get is "reset line is held low"?

"reset line is held low"?

Its an interpretation of the POST card you are using.
So a device or a condition such as the cmos jumper still in place is holding the reset line low, causing the base clock to be off. There are other things that can cause this too, like a damaged cpu socket, or shorted pins in a pcie or memory slot.

Give this guide a whirl;

I've used a coupe of guides in conjunction with the CH341A BIOS Programmer toolkit I have but you might want to clarify which one you have.

I have the CH341A Pro

Are you 100% sure the cmos jumper is not in the reset position? I don't even want to imagine what would happen if you try to flash the BIOS while the board is in reset mode (maybe nothing, but I would not like to try it).

Yo i wish that was the problem. I swear I'm not trolling but I see the clear cmos pins with no jumper on them. This board doesn't have a switch or anything to do that. I need to find an image board to show you all pictures. But if it is that simple I'm gonna loose it 😆
