What's wrong with my motherboard?

Hello, about a month ago I bought a broken ASRock Z390 Phantom Gaming-ITX/ac motherboard and was hoping to fix it. I installed a i5 8600k and 16GB of memory on dual channel and tried it and it turned on but it would not boot up. I also installed a chassis speaker but it would not beep. I took off the Ram too and it would still not beep. I proceeded to try is with an i5 9600k and it would have the same results. So I plugged in a TL460s Plus (Debug Tool) and it would display a the codes 00. What could this be?

I also unplugged the battery for more than a day, CPU socket pins are good, everything physical looks good.

...so you intentionally bought a broken board? You know what makes it "broken" in the first place?

The guy I bought it from sells things like this, I had already bought 4 motherboards with bent pins from him. I had already asked him what was wrong with it but he said he couldn't remember because he had sold a good amount of these.

So basically you and the seller dont know why its broken? Great.

 

If there are no bent/broken pins on both the CPU and RAM slot, then its most likely that the BIOS chip is corrupted or have a bad solder mount. Both you really cant fix without knowing how to reflash it forcefully or how to operate a 5 grand BGA soldering station.

So you dont know how to fix a motherboard, but decided to buy one anyway and see if the internet can fix it over the wire? 101 out of 100 marks for logic right there.

did you at least remove the heatsinks on the board to take a look underneath them?

 

and I assume you already have a display plugged into the iGPU, so the fans are spinning but nothing is shown on the display

Sorry for being so vague but yes I have had it plugged into a monitor both (HDMI and DP). I also have a CH341a programmer and am planning on reflashing the bios.

You need to quote someone to get a respond from someone...

 

Then try. Pinch them in and hope for the best that it can:

1. Read it

2. Flash it.
