I wonder if it might have an internal/external choice in some menu. Since it puts out a image with nothing else attached, we know it has some internal reference capability. It may not auto-switch to correctly handle external sources... or it may be set for PAL or something like that, too...
Of course, it could be busted, as you thought, too... Chip |

I do plan to try the S-Video input as soon as I figure out where those cables are. Quote:

I really did think this might be the reason for the lack of picture related color, but it doesn't explain the shift in this unit's behavior. Since I haven't ever tried it, I'm also not sure what would happen if one were to display a PAL signal on an NTSC TV. I have not tried feeding the unit a PAL signal to see what would happen. I couldn't imagine that Knox Video would have designed the unit such that it had different circuit boards for each television standard. After poking around, it seems the video board can be switched between PAL and NTSC by way of a jumper. A Hitachi HD440072 is used for sync signal generation. It is to be a multi system capable part (for PAL, NTSC and SECAM). There's also no explanation for why the unit clearly seems to be putting out an NTSC color signal...the best I can say is that I don't think it's set up for PAL operation any longer. I was really hoping someone might have some documentation hiding in a forgotten file somewhere. |

Found a couple of links you may have run across:
http://www.videomaker.com/article/17...&gbv=1&ct=clnk http://www.shopping-advices.com/feat...generator.html Do you have the "instructional overlay" outlining basic operation? If not, perhaps one of the auction sellers could make you a copy before sending it away. The video technologies article says the manual is only 5 1/2 pages long... Also, there are two adjustment pots (with hex nuts) tucked up high on the back panel... you may have a go at those... after marking their current position fairly accurately. Best to do once you get video scope going. And with regard to PAL... they (or you) may have modified the unit's main video board output for NTSC, but the video input you're using might still be PAL... which would probably look squirrely. The fact that it snaps into correctness on occasion leads me to believe it's a sync problem. Chip |
