Greetings from Noobland. First build, using a Raspberry PI 3B+ and an SD card I bought on the internet claiming to have NOOBS preinstalled. Sadly on bootup I get these unsettling blue lines on the screen, and no response to keyboard input.
Of course I’ve read suggestions to edit /boot/config.txt. But when I look at the SD on my laptop, I don’t see that file. It makes me wonder if the SD card has the right files… is it possible the card needs new files and/or formatting?
FWIW I’m missing the ribbon cable that connects display driver to keypad… could that be the issue? (Someone told me it’s not strictly necessary, maybe they were just kidding.)
Also, the power button seems to turn the system on, but it doesn’t seem to turn the system off… I know that sounds ridiculous but that’s what I’m seeing.
Any suggestions/hints much appreciated!
