Raspberry 5 boot issue.

Received my 2 rPi 5’s today and I have a boot issue with one of them.

The first booted just fine and it’s up and running. The second one, the light turns green for about a second, then goes back to red. Nothing on the monitor at all. I’m using only the official power supplies, and I’ve tried both of them…same result on board 1…works fine. Board 2 does not. I’ve also tried different microsd cards in both. Same result. Board 2 won’t boot at all. All of this was purchased here at SparkFun.

What can I do?

Is anything else connected to the non-working one? If so, disconnect everything (usb devices, mouse, hdmi, etc)…does the LED behavior change?

Exact same behavior with only the power supply hooked up. Either power supply, I have 2 of the official 5v/5a supplies.
