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 === PCW Expansion port adapter composite video cable ===If you want to connect a PCW Expansion port adapter to a display, 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 lettering. If you use a duble pin header to populate the video output pads on the PCB (as I do when building them for other people, your cable should look like this: {| class="wikitable"|-|[[File:PCW composite video cable.JPG|thumb|Typical composite video cable fitted to the PCW Expansion port adapter.]]|} The wires connected to the PCB are:* Yellow - Composite Video* Black - signal ground I use a female phono plug, cable mounted, connected to the copper shielded cable (standard audio cable, male phono to male phono), which is in turn connected to the Video input of a SCART adapter. This plugs into the back of a TV. Depending on your TV / monitor, you may need a different plug on the end of your cable.
