ACT LED blinks ONCE. Did I brick my Pi 4?
-
I was installing the Pi 4 on standoffs inside a case I'm making and tried to boot it (I check hardware at each stage of a project to make sure it still works). I get a single short blink on powerup with no video output.
I've checked the resources here, https://www.raspberrypi.org/forums/viewtopic.php?t=58151 but one short blink is not mentioned here, which makes me believe I scraped something with a tool and broke a trace or something else fatal to the hardware. Inspection under a 3x magnifier isn't showing any broken traces or components shoved off their pads.

@VictimRLSH have you tried re-imaging or a different SD card?
-
Did that, no go. I also tried booting it with no card, a Pi 4 should blink 4 times with no card, but it still just blinks once and goes silent.
-
@VictimRLSH can you remove from the case and try booting?
-
@quicksilver Also did that, my theory was a standoff displaced a surface mount part from its pad, but didn't actually see any evidence of that. It was running 30mins earlier when I checked it before mounting.
-
@VictimRLSH I would still try with a fresh image on a different SD card just to be sure. If that doesn't work then I would say it's done for.
-
Not a huge loss, these things are cheap. Just chaffes my ass thinking I did something dumb and don't really know what it was. LOL

Replacement arrived and is working in my prototype"Switch" case (almost finished!). However, why did I have to reset my Wi-Fi password if I used the same SD card from an identical Pi 4? It is encrypted with the processor ID?
