I’ve been having trouble getting a recently purchased pi 4B to boot.
When I power it on, I only see a red power light, nothing from the activity light beyond a split second flash exactly as I plug the USB C in. Any screen that I plug in to either of the hdmi ports does not register any input.
This behavior has not changed throughout anything I try.
Things that I have tried:
I am using the official power adapter though I have also tried with a different USB C cable.
Using an SD card with the latest version of noobs installer.
Flashing Raspbian Buster Lite onto an SD card with Etcher.
Tested using 3 different screens to make sure there wasn’t an issue with the screen.
Followed the instructions for reprogramming EEPROM from https://www.raspberrypi.org/downloads/
I have tried these things with two SD cards freshly formatted before running etcher / copying noobs.
I have verified that one of the SD cards I’m using boots fine on a coworkers pi and I see the same behavior when booting from his SD card.
If I have the network cable plugged in the pi does not acquire a dhcp lease.
One of the two SD cards I am using is brand new and the other worked on the coworkers pi.
What else I should attempt before assuming the board is faulty?
Thanks for your time
