Are you talking about the antenna wires? The longest two go in the same track.
The video cable in my MacBook Pro is a bit frayed. This was caused by the hinges being loose or missing screws. I replaced/tightened all the screws, but because of the fraying, the video signal is degraded. It flickers, sometimes loses some colors, or loses half its pixels.
It's finicky. If I put the bottom chassis on an close up the MacBook Pro, the video cable gets pinched enough to ensure the video degradation. However if I keep the bottom off, and keep the video cable positioned just so, not so crowded, then the video signal is fine. However the machine is not much of a laptop if you have to use it with the bottom off, without moving it.
I can get a spare video cable from a junker, but I don't have the heat lamp and suction cups, and anyway am not sure I want to attempt to dissamble the display assembly. Are there any things I can do to improve the functioning of the video cable in place, without replacing it?
I did try wrapping the frayed cable in Sugru. It did not resolve the issue.
