I have an original Japanese gamecube which is modded (red switch on back) to also play US games. It works fine with the default A/V composite cable, but I also have the (now expensive and rare) component cable. It has NEVER worked with the component cable. I power it on, the fan comes on and the power light flashes once and goes off. The disk does not spin. No picture. I've always assumed it was because of the GC's mod - but I don't know. Any suggestions?
