Component cables not working

[wireless]

Hello.

I'm using the red, green and blue component cable for my Telus cable box. Nothing is working or showing up. I have tried resetting everything, turning the cords around... Everything works when I use my hdmi cord. But I don't want to use the hdmi cord anymore.

Why could this be happening? I'm not overly familiar with component cables, especially these coloured ones. I am pretty sure they are the ones Telus sent me a few years ago when I was having hdmi problems. Now they won't work
