Help with troubleshooting headless setup

[bvroo]

Hi All,
My rpi stoped booting recently with no obvious reson. I have a headless setup so my options are rather limited. As I understand the main indicator of problems is the OK LED on board, so right after I power the board it lights up for about a second and then goes off, a few seconds later OK LED start blinking with absolutely no patters (as hdd led might blink on read and write) and then after couple of seconds it stops and never on again.
I also tried to check the logs on SD card. I deleted all the logs with created in 1969 and tried to boot, no new logs were created, so I assume it never get to the point of acctualy booting the os.
does that mean I have some sort of hardware failure or is it anything else? As I said I have a headless setup and no hdmi display to check what's going on there.
thank you

It's possible your SD card has become corrupted, especially if you've just been "unplugging the Pi" without using "sudo shutdown -h now" (or equivalent) first maybe? You don't need an HDMI/DVI TV/monitor to get a display. If you have access to a TV with an A/V input you just need an RCA (phono) video lead (yellow connectors) to view the "low res" screen which is "OK'ish" in "terminal/command-line" mode. For SCART inputs you also need an A/V - SCART input adapter - often supplied with things like camcorders, video/DVD players, games consoles etc.

If you have another computer that you can connect the SD card to you can check if it's been corrupted. Gparted is easy to use and has managed to solve it sometimes when it's happened for me (partition/check) - if it's not able to fix it or can't find the partitions, re-image the SD card, and if it doesn't find any problems with it there's something else going on.

Thank you, I will try this. I was unsure how to check sd card.
