The problem I'm having is that sometimes faint vertical lines, grey in colour appear on my screen coupled with faint greyish scattered pixels. I'm guessing this has something to do with overheating but I wanted to post here to see if anyone have had similar issues or know for sure that it's an overheating issue. The thing is, these lines and pixels first appear after I've had the Wii running for a while. At least that's what it looks like to me, but I guess I'll have to try to check that in greater detail. Anyways, thanks in advance.
