I'm just starting out my very first build but I would love some help with the screen connections.
I'm using a Raspberry Pi 3 and I soldered PP24 to the yellow cable of the screen. No output.
In an effort to debug it, I tested the connection with a Raspberry Pi 1 Model B (I only have a cable for the old Composite Video connection and not the new 3-way Audio+Video). It worked.
I then touched the Composite Video Out with the screen's yellow cable like so:
And it worked...... but only when I have the yellow RCA connector plugged in anyway!
Knowing that the yellow RCA plug usually has a grounded cable for shielding, I tested the Raspberry Pi 3 pin while connecting the yellow RCA cable to the RP1 Model B's plug (that should provide the ground but not the video). I got the same black screen as before.
The questions are:
- What do I need to do in order for the pin to output without a connected cable?
- What can be the problem with the Raspberry Pi 3? I'm waiting for a new 3-in-one RCA cable to further test it.
I'm thankful for any help that you can offer me.
