My Gamecube stoped giving audio since there was an electric outage and now it is only giving video, I already checked and the 12V point is not giving voltage, I was about to bridge the 5v point to the audio amp diode but since this is a NTSC-J I have not been able to find it on any motherboard schematic, please can anyone assiste into which is this diode? So that I can regain audio on the GC?
