No video on Gamecube.

I soldered 5 wires between the gamecube and the regulator board as described but when I plug in the power and video no video comes up, however the power led on the controller port lights up. Is the motherboard fried or is there some sort of fix.

Alright, link to the guide you used, so we actually know what you did, and post some pictures of your soldering job.
We can't help if we don't know how you altered your console.
