Hi there,
A neighbour has an exisitng cable run to a projector location in the lounge bu tthe end has been cut off the cable.
I have soldered a new end on the cable but can only get a black & white picture (all be it a very clear B&W picture!)
There are no crossed ccores or shorts in the cable.
How do i acheive getting a colour picture?
I have the same cable (S-Video 10m factory made) and this works fine with their DVD and projector.
It is in a 2 storey house with no easy way of replacing the cable.
Otherwise, is there anyone in Auckland the specialises in this kind of repair?
Cheers
Phil

S video seperates the color and monocrome parts of the video signal.
Monocrome is 1 volt point to point and color is 0.3 volts point to point.

This then means there could be 3 issues.

1 The pinouts are wrong, here are the correct pinouts.

2 There is a break in the cable somewhere. This will require a cable tester to diagnose. at the worst you might need to attach a new cable to one end and use the old one as a draw cable.

3 The cable is too long and the color signal is dropping. In this case you need an amplifier at the far end. This should only come into play for cables 50 meters or longer.




Hmmmm

Thanks for the reply,
I will recheck the pin outs and also do a continuity check on the cable (hadn't done this before).
Would getting the pairs mixed up explain the B&W picture or do you need connectivity for only 1 pair to get a B&W picture?
Distance isn't the problem as i have exactly the same cable(by good luck & not good management!) and this cable has no issues displaying a crystal clear colour picture.
Cheers
