Reboot and Dead?

I have Ubuntu 20.04 running, I did an update and reboot and it didn’t come back after a few hours. It wasn’t replying to ping, so, I unplugged and replaced power. I now see this message on the display, external video doesn’t work either. Any ideas?


So, not sure if it was a combination of something stuck or not, but it seems the microSD card got corrupt. No idea why the weird display or why it wouldn’t turn on (LED button stuck?). Replacing the microSD card as the old one booted and said to run fsck, which produced:

unable to set superblock flags on writable

So, swapped card, works again. But LED seems defective, only the top row shows up. Anyone know if the LED can be replaced?
