RESOLVED - Component over cat5 Balun random black screens
I’m running component video over cat5 baluns and get random video/audio dropouts from a 720p 60hz source resulting in a black screen then the image comes back. The run is about 110ft.
Thinking I just needed a better Balun I changed out my Tripp light cat5 baluns for muxlab baluns and still get the drop ours.
The next step I took was to connect up another cat5 cable I had run. Still drop outs.
Next I moved the video output on my Extron to another known working output port on my Extron switcher and the dropouts still happen.
This same source is distributed to other TVs in the house with shorter runs and the droputs do not occur.
So either I got 3 bad cat5e cables run to that location or multiple bad baluns or some kinda interference is causing the issue.
It’s also inresrfing to note it appears that that specific source of 720p 60hz seems to trigger it more than other sources I set to 720p.
I’m wondering if skew in the car5 cables is causing the component video to lose sync at times?
I know I gave excessive skew as I can see shadow boxes around characters using my cable. I got the cable from monoprice. It’s 24awg cat6 solid copper shielded with a drain wire connected to shielded connectors.
What should I test next before replacing the cable runs.
I have resolved the issue. The resolution was to strengthen the specific sources hdmi output by removing a monoprice hdmi port saver at the end of a long hdmi cable run. Apparently the length of the input source coupled with the long output location caused the component video to drop out from time to time. Never knew component video could just drop out from time to time if signal strength of it degraded too much but it can.
