s-video carries luminance and chromanance. In simple terms, luma provides a a black and white picture, chroma the color data. without chroma, you get no color. Either - the cable is bad (usually in the form of bent/broken pins in the connector ends - the source device is bad - the projector input is bad

SOURCE: brightness of picture
If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.

SOURCE: there is no picture
just a shot in the dark. this reminds me 'bout a problem with a Optoma (or maybe it was a Ask) i fixed. In that setup menu (on the proj), i was able to adjust the sync signal on the input. (I don't mean the the screen refresh rate..) Just tried gradually step by step. Worked then!
