I have connected the Adafruit screen to the RPI0 for testing purposes and I can not get it to connect to the composite display. If I plug in an HDMI Cable I get output just fine. I have adjusted my config.txt file as others have suggested after searching for the issue online but it still does not work.
The screen turns on and gets power from the Pi and shows AV2 in green letters and that is it.
Please see these pictures:
Steps I have tried:
Reverse the yellow and white inputs on the Pi. -Fail
Connect only Yellow on each port on the Pi. -Fail
Any help would be GREATLY Appreciated. Thanks!

Re: Composite Screen Not Working
Your white wire on the Pi is connected correctly to the TV pin, but that yellow wire is connected to a ground pad on the Pi.

Re: Composite Screen Not Working
so I need to put the yellow where the white is currently and what about the white? do i splice both wires to the same port?

Re: Composite Screen Not Working
the yellow and white wires are separate inputs - AV1 and AV2. you should only connect one or the other. it doesn't matter which.

Re: Composite Screen Not Working
you just need to connect the one ground wire somewhere on the pi. some people attach two ground wires (at the same pad on the tv board) and run one close to the power and one close to the comp signal. that can strengthen the video signal, especially if you twist the ground and signal wires. but it's not strictly necessary. if you have a lot of static or bad picture quality, you could try that.Enviola wrote: ↑Tue Jun 30, 2020 6:30 amAhhhhh.... see i didnt know that!infinitLoop wrote: ↑Mon Jun 29, 2020 4:29 pmthe yellow and white wires are separate inputs - AV1 and AV2. you should only connect one or the other. it doesn't matter which.
