Since I installed the HBC, in May, I've had this problem; my health screen is black and white, and when browsing in the System Menu, the sound bugs. Ex; Once out of 2, when I load the SM, the sound play for about 3 secs, and then stops suddenly. Sometimes it plays normally. Same thing happens when clicking on channels. Sometimes the sound works great, but sometimes it stops suddenly. Should I format my Wii?
