You may find it necessary to adjust the trimmer to get a signal. When assembling, set the trimmer about half way to begin with, then adjust it in situ until the best picture is obtained. Don't forget, you're going to need to make up a suitable video cable, too. The composite video signal is on the pad closest to the trimmer, with the ground pin next to it. This is marked on the board in tiny lettinglettering.
