HELP I HAVE A RFU ADAPTER FOR NINTENDO 64 AND I HOOK IT UP BUT NOTHING HAPPENS. AM I HOOK ING IT UP RIGHT?

Think I know the problem. It might be the jumper pak. If it is then it would be a cheap fix. This guy gives a good demonstration http://www.youtube.com/watch?v=WqQorcCz4hE

a Playstation 2 adapter is only meant for playstation

You need the colored cords to hook up into the back of your TV, and you need to keep in mind that a power adapter is needed too to plug into an outlet.

Important Note:
We highly recommend you review the following precautions before you set up and operate your Nintendo system:
Important Safety Warnings & Precautions
Hardware Precautions / Maintenance
Game Pak Precautions / Maintenance
Precautions Concerning TV Screen Damage (Image Retention)
Installation Steps:

Locate the Audio/Video inputs on the back of the TV.
Place the yellow end of the Stereo A/V cable into the Video "in" on the back of the TV. Connect the red end of the cable to Audio "in" Right. Connect the white end of the cable to the Audio "in" Left. Use a slight twisting motion when inserting the each cable and ensure the cables are firmly pressed into the input.
Note: If you have a mono television with only one Audio input, click here for a diagram of how the hook-up will look. The Y-adapter pictured is optional; you can also simply leave the white cable disconnected instead.

Connect the rectangular (gray) plug of the Stereo A/V cable into the "multi-out" connector on the back of the Control Deck.
After system is connected to the TV:

Insert Game Pak fully into the Control Deck.
Plug the Controller(s) into the front of the system using the left most port for Player 1.
Plug the AC Adapter into the back of the system . Plug the other end into a wall outlet.
Slide the Power Switch on (toward Game Pak).
Turn on the TV and locate the input select. It's often called: input select, AUX (auxiliary), Line, Line In, Input, Source, Select, In, or EXT external). Switch the input select to show the Nintendo game.
The game image should now be displayed on the screen. You're ready to play!
If after following these directions completely you are not able to view the game, try our Troubleshooting Tips.

Most if nto all RFU conenct to the coaxle connection on you tv.
If you have a newer tv monitor many do not have coaxle conenctions anymore only RCA/HDMI/C-RCA if this is the case on your tv you'll need to

#1 get rca wires for your 64 (easy cheaper)
#2 get a rf to rca converter (harder more expensive)

You can find power cords for the Nintendo 64 on eBay. Here are some that are for sale right now:

the gamecube video cables will work.

You need a switch (transformer) to connect it to the incoming signal antenna screws. You will probably need to adapt it to a cable tv plug. The wires you connected are for the sound.

Well its a power supply failure symptom for this to happen now.
