My N64 has always worked. But recently it has not been sending a signal to my TV. The red light turns on to show that it is on, But my screen remains black with no picture nor sound. I have tried resetting it and putting the cables in and out but it still doesn't send a signal.

Well you could buy and try a new N64 ac adapter to see if it makes a difference then.
For my problem with no red light showing up on at all I talk out the old motherboard and install a new one then.

Have you tried a new expansionpack yet. I tried putting in a new expansionpack for my 14 yearold N64 console and it worked again after that, It might just be that then.

I had an issue like this with my 14 year old N64 console so I tried a new expansion
pack in it and it worked again after that then. It could just be that.

Adjust the vertical or horizontal hold controls. This is helpful even if regular TV stations come in fine. If your TV has an automatic fine tuning control (called AFC or AFT), turn it OFF. Use the manual fine tuning dial to adjust the picture. If turning OFF the AFC/AFT causes your TV to display in black and white, then leave the AFC/AFT ON. Slide the Power Switch on the Control Deck to the ON position. While the control deck remains ON, turn the TV off for 10 second then back on again. This resets your AFC/AFT so that it will tune in the signal from the control deck.

Move your control deck farther away from your TV. If the control deck is too close to the TV, the control deck may cause some interference.

Well if it freezes and the screen turns black and than the tv screen says no signal and the light is on i had a problem like that with my 14 year old N64 console so it looked like it was dead and died but it was the expansion pack that did this it makes it look like it died but it didnt.

maybe it's just the T.V I mean the N64 is like 10+ years old and you're trying to get it to work in a new T.V! I reckon that your best bet is to buy an older T.V to play it with or get an emulator e.g PJ64 on your computer and then you can still play your games

I have the same problem and from what I've read elsewhere on the net, it seems to be easily amendable by one of two solutions.

- You can re-tune a channel on your TV (not one of the main ones) and it will find the frequency for your N64 to run on

- If you had a gamecube the yellow, red and white output cables that came with that are (apparently) compatible with both the N64 and SNES and that way you wont have to tune your TV.

Unfortunately for me, I did not have a GC and my TV will not re-tune due to the button on the controller not working! Good luck.

I bypassed the stereo reciever and plugged the cords into imput 2 in our tv. It works fine.

If its got what looks like a cable jack plug, its an RF Cable. As is, if those get kinked up badly enough, the copper inside of them can become damages, which can affect the way it sends the signal to the tv from the N64. Those cables can be picked up from local game stores. my suggestion though, is if you have the connectors, go with the Red,Yellow,White setup, Red and White are the sound cables, and the Yellow is your video. Better sound from it.

try using the cables instead of RFS's
