I didn't know it made a difference but the ground needs to be from the same Pi as the video signal. I improvised a connection between the yellow R...

Same exact result with all variants of config.txt. Let me stress that I'm not using an RCA cable on the RPi3, I'm trying to connect PP24 from the RPi3 to the screen, is that what you're doing as well with your Pi3? Check the red circle in my photo for a RPi1B equivalent. So right now my hypothesis i...

Both Pi work fine with HDMI and I'm using the same SD Card to test them, so I doubt it's config.txt's fault. Full disclosure: because I'm using a Rpi3 Retropie image, the old Pi falls back to terminal on boot, stating "Illegal instruction". I'm not too concerned because it's precisely that same Pi t...

No output. In an effort to debug it, I tested the connection with a Raspberry Pi 1 Model B (I only have a c...
