Talk:Nintendo SNES / Super Famicom

Grayscale Image
I can't flesh this out to the required quality, but for the symptom of **entire image is grayscale** the problem might be the color carrier frequency being out of calibration. The fix is to adjust the red potentiometer-looking component (actually a variable capacitor) by the crystal (small silver rounded rectangular component by the S-CPU for the US SNES). Connected to a TV, adjust it until you get color again, then adjust one direction until you lose color, then the other direction until you get color and lose it, then to a position between those two points. This leaves a margin for error in either direction. I've fixed a couple of consoles this way.
