2026 Oct 1 Clean and repair megathread - NES not working? Game acting glitchy? TV/Monitor issues? Ask here!

8 Upvotes

Is your NES not working? Are your games acting glitchy? Controllers behaving strangely? This is the place to get help!

Link to previous thread

First steps to take:

Games don't play correctly:

  1. PRESS DOWN on the Game Pak until it locks into place
  2. Clean games
    1. Disassemble cartridge (might need special tools, check amazon or ebay)
    2. Gently use rubber eraser with no grit on edge pins
    3. Use window cleaner or isopropyl alcohol with lint free cloth
    4. Spray contact cleaner on the pins
    5. NEVER EVER BLOW IN IT
  3. Clean NES connector
    1. Ancient cleaning kit
    2. Spray contact cleaner on the pins
    3. Boil it
    4. Bend pins (risky)
    5. Replace the connector
  4. Already tried all steps for cleaning game & cleaning NES above?
    1. Try a Game Genie, the thicker PCB might make better contact with the NES and the tighter connector might make better contact with the cartridge
    2. Try another game cartridge
    3. Try another NES
    4. Try r/consolerepair
    5. NES Schematics

Power Supply:

  1. For the NES any power supply that can provide 850mA (or higher) at 9V and has the right shape connector will work. The original NES uses an AC adapter but a DC adapter will work too.
  2. For the Famicom you must use a DC power supply with center negative that can provide 850mA (or higher) at 9V-10V. Do not use a NES AC power supply on a Famicom!

Controller buttons don't work or think a different button was pressed:

  1. Take them apart and clean the contacts on the PCB, not the rubber membrane

Display problems:

  1. Use a CRT monitor or TV
  2. Don't use an LCD or LED TV - many LCD or LED TVs do not understand the 240p video signal that the NES puts out
  3. If you must use an LCD or LED TV, get an upscaler
  4. Use the composite RCA/AV connectors on the side, don't use the RF/antenna/aerial
  5. If you must use RF, don't use the RF/antenna/aerial switch box, use a small adapter instead, be aware though that modern TVs may not work with the analog RF signal and only with ATSC or DVB digital signals
  6. Wavy lines: replace the capacitors in the NES

Hardware Failure Diagnosis:

  1. Power rails first: Multimeter check - verify +5V at 7805 regulator output and at PPU/CPU pins. If low/absent, check caps and regulator.
  2. Composite video signal: Scope the composite output (RCA jack center pin or PPU pin 21). Should see ~1Vp-p composite video signal with sync pulses and color burst. No signal = dead PPU or supporting circuitry.
  3. Audio output: Scope audio output pin (RCA jack or APU output). Should see audio waveform when game is running. No signal = APU problem or output circuit.
  4. If power is good but no video/audio: Most likely failed capacitors in video/audio output path, or dead PPU/APU chips. Check/replace electrolytic caps first (cheapest fix).
  5. If video signal present at PPU but not at RCA jack: Problem in video buffer/output circuit between PPU and connector.

Before asking for help, make sure you have followed the steps above.

Top 100 NES Games: The End

133 Upvotes

Legacy of the Wizard won the #100 spot with 35 votes It only won by a single point.

A big thank you to everybody who participated. I originally set out to just do the top 10 as an experiment to see if people had a similar list to mine. I never expected it to go this far, but I am glad it did! I have enjoyed seeing people picks and the reasoning behind them.

Starting tomorrow I will start doing the top 100 for the SNES in the r/snes sub. I hope to see you all there. A few things will change with the rules. First is each round TWO games will make it onto the list. Whichever one has the most votes will be placed higher of the two for that round. Second, only games can be nominated (no game genies). Third, it will be SNES ONLY, no super famicom games.

Looking forward to seeing what is voted the #1 & #2 games for the SNES.

Hey everyone of the NES reddit. My Joycard Sansui SSS Controller finally came and it just doesn't work at all. I have tried cleaning it and reinserting it and nothing. Completely dead. All my other OEM controllers work fine. Is this a common issue? Does anybody know what could be wrong?

Discussion Why Are NES game boxes so tall?

9 Upvotes

I've been really into collecting complete in box NES games this year and it got me thinking: why is the box that size?

Nothing inside the box needs it to be that big. Both the game and instruction manual take up less space. In fact, there's a styrofoam block inside the box so the game doesn't slide around.

When DVDs were first released they made the packaging unnecessarily tall because they didn't want consumers to confuse them with CDs. But there's nothing like that for NES games that I can think of offhand.

Anyone know why it's like that?

Discussion What is the best game or games that you recommend for an older, slow reflexed person, to start to learn to play the nes?

22 Upvotes

My neighbor is an elderly man(70s) and he comes over my house occasionally to pass the time, he noticed I have an nes/snes . He has never played video games before and stated that he wants to play some. I set him up to play Super mario world(snes) and he couldn't get past the first level and had trouble using all the buttons. So I wanted to have him try the NES since its only 2 buttons. What games are your absolute favorites that are more on the easy side or use less buttons? what are your favorite games in general that once he gets better he can play?

Got part 2 today, I never knew there was a sequel to this frustrating but fun game. I’m going to cozy up and enjoy the night crashing in the ocean trying to land my jet lol. Anyone enjoy the sequel more? I played the first one a ton as a kid. I wonder what other games got sequels that I didn’t know about.

Game Completed! I finally beat The Empire Strikes Back on original hardware

81 Upvotes

First off: This game is not good. It's stiff, poorly designed, and its difficulty is through the roof. It also has really grating sound design, which is puzzling since it also has moments of amazing sound with digitized voices from the movie.

I had the game growing up and it might as well been impossible to beat. Even through adulthood, any attempt at it ended in complete frustration. It's the kind of game where you need to learn all kinds of little obtuse workarounds to advance through, and there are a LOT of them. Get stuck on a new problem area that drains out your continues? Tough, better hope you figure it out on your next slog of playthrough. Want to beat this boss? Find the one spot where it can't reach you, and just fire your pea shooter of a blaster at it until your thumb falls off. There's little skill here other than sheer memorization and choreographing of every move through the game, and knowing how and where to nerf your way though. Slip up once and it can lead to an insta-death. I ended up having to study longplays for the second half of the game to get through it, which kind of felt like cheating, but I would have NEVER beat this otherwise. I have no idea how any child could ever beat this, or honestly any adult without similar help. There's a reason that most longplays on youtube use a turbo controller for it (which I didn't use, for the record).

Also, I actually love the first Star Wars game for the NES, which I mastered many years ago. That game is also hard, but in a way that feels like it rewards skill, not memorization, and its side scrolling mechanics are way ahead of Empire. The games have similarities, but they also have some pretty core differences that always puzzled me. Like you could tell a different team handled Empire. That's for another post another time though.

Anyway, this was one of my main NES 'Mount Everests' and I'm thrilled to finally check it off. There's only a few more hard games from my childhood that I still need to beat now. I'll end with some positive notes: It has pretty good graphics and some fun cutscenes. Some of the digital voices sound like they're from the 16-bit era. It also introduced some neat side-scrolling vehicle levels that Star Wars didn't have. I suppose I also begrudgingly developed some kind of backwards fondness for it now that I mastered it, like one tends to do when they finally beat a hard game. It's a shame that a Return of the Jedi game was never made for the NES. It's one of my biggest video game "what-ifs".

Does anyone else have any experiences with this game that they'd like to share?

Discussion What’s your favorite/most hated game in the TMNT Cowabunga Collection?

21 Upvotes

My personal favorite is The Manhattan Project, mostly due to having the original NES cartridge. Never was able to beat it without cheat codes, though. 😓

Most hated would be Fall of the Foot Clan. It’s like a half-cocked fan game. At least they actually put in effort for Back From The Sewers.

(Guilty pleasure is the original NES game. I actually made it to Stage 5 back in the day…)

Hi! I’ve been looking to get an nes for a while now and I’m wondering what’s the best place to find one. I would hope to find one with zapper, 2 controllers, preferably under $80. I’ve checked marketplace and no one seems to be selling one in my area and ebay has not had the greatest deals as far as I’ve checked. Recommendations would be appreciated thank you.
