Since repairing Wiis, both me and erikie have been wondering what causes a Wii to work over component and not work over composite (or the opposite).
erikie first suspected it was the AV encoder and as I had to tools to remove and replace the chip with little hassle, it was upto me to try it.
Well, nearly a year later I have actually found time to test this theory and its CORRECT!
I have now repaired a board that wouldnt output over composite (and therefore not fit for resale).
Here is a picture of the location of the chip when its removed:
Notice the large ground on the bottom of the chip, this can make removal difficult. Also when you replace it, you will need solder paste on the underside of the chip to reconnect this.
