Nintendo 64 has power but does not work

SOURCE: Nintendo 64 HDTV

I am not an HDTV expert but I believe they are all backwards compatible so the fact it is HD should not be a problem. Have you tried a vcr or dvd player on the same hook ups? It is possible you are trying to use a video input that is already in use? I know on my TV I have the DVD hooked up with an S-video cable to "Video 2". Right next to the S-video hookup are the red, yellow, white RCA jacks. On my TV these can't be used when the S-video is in use so I have to have the games hooked up to the front panel "Video 3". I would disconnect everything and try hooking the N64 up in each input to see if you can find one that works.

If you are using the original AV plug for the N64, it will probably not work on a new TV.  You must find a new AV plug in a store, or on eBay, Amazon, etc.  This plug must have the red, white, and yellow ends to it.  those are the color coded ends that go into the TV.

Yes you will, you will have to find an un assigned channel and get the tv to fine tune it in.

SOURCE: Nintendo Wii AV Cables not work

The AV cable that came with the Nintendo Wii is not designed for high-definition TV (HDTV) or enhanced-definition TV (EDTV) to view 480p progressive output. If you are connecting to a 480p TV, you will need a Wii Component Video Cables (maybe like the Gamestop cable you have).
