Wii Cables Component

Is there any chance that 3rd party Nintendo Wii component cables could harm the Wii? A rep told me it would.?
I have a graphical issue that is being fixed by Nintendo. The rep told me that using 3rd party cables could cause the system to have problems. This seems unrealistic, and possibly a way for Nintendo to boost it’s own cable sales. By the way, the Nintendo cables are at least $10 more than the third party ones. Any help?
Ive got a 3rd party cable and have done since the release of the wii and ive never had any problems.
The nintendo rep is obviously just trying to get you to buy nintendo stuff to make them more money!
