I have a few dead motherboards that have this chip on them but cannot tell if they work. How did you identify this custom as the culprit?

So basically I’ve been having an error when it boots up seeing if all the roms are good and it says that 22D had an error so I replaced that and it was still saying the same thing so I did the part when you hold the test button to turn it on for it to sync and it just did nothing someone I was talking to said another reason as to why it’s not working was the Rom I’m showing can cause it so I resoldered it and I actually got pass the screen it got to the Konami screen and then it went back to the Rom checker so I’m confident that’s the reason

Thanks
