Nintendo 64: Player 1 Port Not Working?

Fri, 11 Apr 2025 11:12:38 -0700

Hey! So I bought this N64 on eBay knowing that the first port didn't work. It looks like someone dumped their juice box or something into the first port because it's all corroded. I gave everything a good scrub and an isopropyl bath. I've soldered the controller port and it seems to be working for player 2 (as it always did) but player 1 STILL won't function. It seems to be getting continuity and 3.3v as far as I can tell. Any help would be appreciated.

Nintendo 64: N64 turns on but not sound

Fri, 23 Feb 2024 13:55:33 -0700

Decided to try and play some games on it and found out I get no sound what so ever. Board looks fine and I do not see any signs of damage anywhere. I get 4.4 k ohms across C140. I have checked the other thread but none of that works.

Nintendo 64: Why won't my N64 output video?

Sun, 26 Nov 2023 16:14:21 -0700

After my original power cord died and I got a new one, my N64 hasn't outputted video or audio. I've gotten new cables, sprayed the ports with compressed air, repeatedly took out the expansion pack to see if that'll change anything, but nothing. I have no idea what's wrong with it. Anyone have any ideas? I'll try basically anything at this point. I just wanna play pokemon snap.

Nintendo 64: Distorted audio in N64 even after re-capping

Mon, 02 Oct 2023 19:30:14 -0700

I have an N64 NUS-CPU-03, I replaced all the caps, I even replaced the U2 (AMP) and U4 (VDC-NUS) and U5 (ENC-NUS)

Everything works, video, controller, even audio, but it's very very distorted. Any ideas? Any suggestions?

Nintendo 64: N64 Not Sending Audio/Video to TV

Sat, 29 Jul 2023 09:29:51 -0700

My N64 abruptly stopped sending audio and video to my TV. The system turns on (the red light in the front lights up), but the TV says it doesn't detect any input signal. I did a bunch of troubleshooting including:

connecting to a different TV
trying different game cartridges
cleaning the connectors
reseating the memory
replacing the adapter

The only thing that worked for a hot second was replacing the adapter, but the second time I booted up the system it was the same problem. Is it possible it's the graphics card? Is that repairable?

Nintendo 64: Console plays some games, blacks out in others

Tue, 18 Apr 2023 18:54:34 -0700

My Nintendo 64 console will play smash brothers just fine but when I try to play Mario kart it goes black at the select course. Works fine on my brothers console. This is the third time I’ve tried to buy the game and each one behaves the exact same way. Any idea what’s wrong with the console?

Nintendo 64: Freezes about 5-10minutes into a game

Tue, 11 Apr 2023 08:06:27 -0700

I can put the game in and start it but right when I'm getting past all the play menus and options and into the actual play of the game it freezes. Some games are quicker than others but it mostly happens to every game.

Nintendo 64: N64 this device cannot save/load

Thu, 23 Mar 2023 06:59:19 -0700

Hello!

I recently bought a n64 with world cup 98 and I get a message when I turn the console on that says : "This device cannot save/load data"

I even bought a new controller pak/controller/jumper pak but that did not solve the issue and I could not find anything on the internet about this. Otherwise everything is working fine, but i don't know how could I fix this problem. If you have any tips for me I am happy to hear it.

In case somebody stumble upon the same problem. I couldn't figure out the problem until I bought Rayman 2. At the start up I got this massage that the Controllare Pak damaged and it may attept to fix it. I let it try and now it is working .

Nintendo 64: Why do I lose my picture but I still have sound?

Thu, 26 Jan 2023 07:39:37 -0700

When I start my games I have great video quality. Then it changes to static and goes out completely but I still have sound. I have cleaned the game slot and the games, but it didn't change anything. Reading on here I scene mentioned the expansion pac trick. That didn't work either. I also saw about the changing of the video capacitor. However I have not been able to find that one. Can someone please send me a link to it? If you also have other ideas please let me know? I have new AV cables also thinking they went bad. Any help would be greatly appreciated! Thanks.

Here's a picture of the capacitor

Nintendo 64: No power or light on console until I strip it down.

Tue, 10 Jan 2023 09:12:07 -0700

So my n64 was working fine. I opened it up and deep cleaned it cause it's never been done. Now I have no power or red light. I opened it up and stripped it down to the main board and plugged it in to follow the voltage, and it turned on normally. Thinking I somehow fixed it I put it back together but it would no longer turn on. It only works when its stripped down. I bought a new power supply, but it made no difference.

Nintendo 64: Turns on, but randomly resets to black screen.

Sun, 27 Nov 2022 17:21:05 -0700

It has happened only recently, but with multiple games I've played the system will randomly go to black screen like it reset itself too. It is one of those transparent cases and I can see there is damage to the second player port, just the plastic from what I can see. Any ideas on where to start looking?
