GCN Image brightness

[stonemonkeylives]

Hey guys,

I was wondering if someone could help me. I was recently given a Nintendo Gamecube, it came with no cables or anything so I bought a cheap component cable from eBay and a friend gave me an official power supply.

I've cleaned the GCN inside and out and tested it with a quick sports game I was given with it, everything worked fine. I recently bought Super Mario Sunshine for it and when I tried playing it, the graphics were incredibly bright.

All my other retro consoles are running fine, just the GCN. Do you think it's an issue with the console or could it be the component cable (I don't have a spare, so I can't swap it out).

Any help would be much appreciated.

The official component cable for the Gamecube uses a custom chip to decode the video signal. The cable sells for ridiculous prices on ebay. My guess is that your 3rd party component cable isn't handling the video signal properly.

Yeah turns out the PAL AV cable has a resistor and capacitor in it that the NTSC one doesn't. So when you use an NTSC AV cable with a PAL console you get the brightness issue.

Ordered a new cable that is specifically for PAL and using a spare SNES AV cable as a temporary fix. Thanks though.

Glad it worked out. Sounds like you're actually using a composite video cable (yellow & white/red) and not a component cable (green/blue/red & white/red). The component cable for Gamecube is expensive because it's the only way to get 480p video from the system. Big improvement over composite.
