Raspberry Pi maladies

[Rhianwen]

My poor Raspberry Pi 4 B appears to be ill, it seems no matter what I do, I can't get a signal to the monitor... be it messing with the config file or flashing a new OS to the SD card. Only thing I haven't tried with the config file was boosting the HDMI signal to the TV. However, I encountered something bizarre that I can't easily find online.

 

The red power light stays lit, okay that's good... but then there is the green one that just consistently blinks at a quick pace, no particular amount of flashes or anything although it does have an "arrhythmia" to it. Everything I seen online states that an application is running or its writing/reading code, but the Pi also does that when I power it on with no SD card inserted. I am hoping that it's another one of those instances of me missing something so absurdly obvious because I love my Pi quite possibly more than my gaming rig.

 

(Also I have to leave to college classes soon, so if I disappear for more than a few hours, that'll be why)

The green light blinking is perfectly normal, just because it doesn't have an sd card inserted doesn't mean it's not doing anything. As for the display issue, do both video outputs not work at all? Have you tried using a different cable or a different screen? Has it ever worked before with this setup?

Yeah, both HDMI ports show no output to the monitor. I don't have another cable for it to further test if that's the issue and I do have a second monitor for it I will try later (that monitor being the one I am using now) but I will say it has worked fine with this setup before. I haven't touched it in a long time and I simply re-flashed it with Lakka, then RecalBox and it didn't wanna work since.

Maybe your sd card died?

It's possible, but is there any way that I can know for sure? I can still plug it into a card reader and it would behave just fine in Windows.

The simplest way is trying another sd card.

The FAT32 file system is very basic and doesn't necessarily report corruption or defects in the drive. You'd only find out when trying to read the files in the corrupted region. You can use an utility like the built-in chkdsk to scan it for problems.

Alright, I tried a different monitor and a different SD card, sadly no results. My best guess is that something is going wrong with the flash process but I have no idea what it could be, everything that the Pi needs to boot seems to be there.
