Reply To: Composite Pal CRT TV configuration

[Arnaud]

Normally the raspberry detects you are using RCA because no HDMI cable is plugged in.

I use PAL CRT as well and the only issue I had in that regard is that sometimes you need to switch on the TV first in AV channel and let it wait until it is completely initialized. Then, and only then, switch on your Retropie. What I had is a blinking screen when this happened.

That did the trick for me. Also make sure HDMI force mode is not enabled in your config.txt file.

Hope this helps
