How to Fix a PAL Gamecubes Brightness Problems




First time that I'm doing an instructable so bare with me!

So I've been having problems with my PAL Gamecube being too bright. I've used my Google-Fu to find a fix for it but I've only come across things related to other Nintendo consoles (N64 and SNES).

From all the pieces I've gathered around the internet I've found a solution to this problem.
It happens when you use an NTSC version of the Gamecube A/V Composite cable on a PAL console.

I've done the following and it worked pretty good.

You will need the following things for this mod:

1) an A/V composite cable (Which you can buy from ebay for like 3$)
2) a soldering iron
3) a 75ohm resistor
4) a hammer
5) a bit of soldering tin

Basically you solder the resistor from PIN #3 to PIN #7 and #8. The resistor lowers the brightness of the picture making it normal as it should be!

Take the hammer and gently brake apart the plastic around the cables input side (the side you connect to the Gamecube).
I haven't done this on an official cable because it would be a shame to wreak one, just buy any one of those cables they sell on ebay for a few dollars.
Solder the resistor to the #3 PIN (the yellow cable) and the other side to the #7 and #8 PINS.
And that's it!

This site helped me alot!

    thanks for the guide! i used a 38ohm resistor as suggested in the comments and it looks perfect.

    That was an easy fix. Thank you for posting it. I used a 38 ohm resistor instead of 75 ohm, and the picture is perfect.

    Tip: If you cut of half of the legs of the resistor, you can easily put it all back in the casing of the cable.

    But if the problem is that the av cable is NTSC wouldnt it just work to replace it with a PAL cable?

    The correct resistor is 38ohm as that is what Nintendo use; 75ohm is too dark. If you have another 75ohm resistor, put them in parallel, which halves the resistance to give about 37ohms. Try it and you'll see it's the right resistance.

    Will give it a try when I get my Gamecube back. Thanks for the tip! :)
