RGB signal gives black screen

Recommended Posts

Hi guys,

I have a strange issue in that my RGB feed gives a pure black screen?

 

The input is 3 x coax feeds (Blue, Green and Red) into an encoder. I have had some success but usually the encoder outputs a pure black screen. There is some talk that the 30M coaxial cables may be just too long for the encoders sensitivity? When I connect a monitor via VGA it works every time!

 

Any suggestions?

 

Thanks

Kevin.

Hi Tom,

yes, unfortunately it is an old analogue switch, so I am stuck with RGB.

 

The encoder is a Kramer VP-101 which then goes composite into a Bosch encoder to get an IP output.

 

What do you think about the coaxial cable length, could this be the issue ?
