Well to make a long story short I was trying to mod my gamecube then It didnt work right away so I dont remember what happened and now when press the power button on my gc only the fan works. No gc led or disc spinning with black screen. I was using qoob pro.
this has been asked and answered before, look back at the previous posts way back! Sorry aint got time to give link!
I removed some solder off the board and made sure there werent any solder bridges and when I did that It worked. I then soldered teh qoob pro and it worked too.
