So I've bought an adafruit screen as shown in the guide but don't seem to be able to get an output. I have the retropie OS on a SD card in my raspberry pi zero (1.3V) and connected it to the power supply with no luck. It's probaly something stupid but any advice would be appreciated, thanks in advanced.

Shown are my soldering on the pi and composite screen board as well as my power supply (on left)
