Question Video Signal Issues

[NLG]

I get wavy, faint, diagonal lines that run across the screen when the wii is on. When it turn the wii off but keep the display on there’s no lines. I tried using a shielded composite cable but i still get these stupid lines. Has anyone else dealt with these?

Thanks

Is your composite wire touching any power wires?

Shot in the dark, but what reference ground is the screen signal ground connected to?

Can we get a picture of your setup? It'll help us see what's going on and help find the problem.

Fans and regulators both can cause this. I found that moving my ground to a place far away from the regs and fan's grounds helped (as well as shielded wire).
