Portable Tv Connection I Can't Get My Nintendo 64 To Tune Into My TV, Neither Aerial Or AV Connection?

I can't get my Nintendo 64 to tune into my TV, neither aerial or AV connection? - portable tv connection

My Nintendo 64 was always worked in our old portable TV that uses the air link, but the television was broken. We have a new, but I can not hear! I have the antenna as usual, but does not seem so often when I try to integrate, so he tried the scart cable, but also the AV channel, nothing will be displayed when using this method. There was never a problem with the Nintendo 64, and worked until the last television was broken. Has anyone tips or know what is the problem? Thank you in advance.
