This channel is literally a goldmine for someone like me who's trying to get into restoring and repairing older consoles. Your videos are super informative and straight forward and I'm so glad I found them along with RetroRepairs. Keep doing what you're doing, man. You're helping us out more than you know and I wish you the best with your channel.
Cuh Shark thanks I know things have been slow, I’ll try to get more stuff up soon
I've subbed. It's good to see someone still doing this. A lot of the old channels have either stopped doing this kind of thing or have gotten super lazy about it. John Riggs, though I love the guy, has gotten down to "cleaning the cartridge didn't fix it, sorry it's broke, guys. bye"
Thanks for the sub, I’ll try to keep the content coming. As far as, John Riggs I’ve noticed that too and that’s very disappointing and underwhelming.
Edit: I just ordered some N64 cartridges hope to get them working. Cross my fingers and hope they’re broken so I can have more content for the channel.
wow that was a lot of work, I can see why you despise the fake restorers. Nice to see them working again after all that effort!
I’ve gotten much better at SMD rework since this video, thanks for watching.
If i had the space I would save up all the spare parts I get too! but my wardrobes are full of working consoles/controllers and same goes for under my bed... cant wait to move... Love your vids ! Super inspiring!
I know the feeling
This is a fantastic video! I’ve always wanted to try swapping some of the board chips.
Thanks for this video, I was able to rescue a SNES. Subbed.
Cool, thanks again👍
It's amazing how much just a good cleaning can do. Way to stick with it on that second console though. Troubleshooting at its best.
I’m always amazed too.
what you do is an art man, thanks for the videos, I've got a black-screen snes and I don't know where to start, just thinking...
Thanks.👍
Your a pro love the videos awesome 👍😎 helping the SNES stay alive I wish I had a 2 chip doner board😢
Thanks for the kind words. 👍
Your welcome 🤗 thank you again I need your help I'm going to watch your videos and do a capacitor kit replacement and regulator on my SNES I'm waiting on a burn in test cartridge I got all the equipment that you talk about I'm a novice but learned a lot from my uncle that passed away he could literally fix anything he fixed floor model TV's and stuff like that all the time his house was always full of electronics he taught me with the circuit game that teaches you what different transistors, capacitors and diodes do in different ways you could snap them in the circuit board it had a speaker that would make different noise so when put together in different sequences it would teach you how the power would pulsate good memories I wanted to share 😊
@@user-ig9fr4fb9h that’s very heartwarming story. Hopefully you were paying attention when he was teaching you. Good luck with the repairs.
You need to get yourself a dental pick (Walmart in the dental care area) so you can gently probe the pins to see if they are loose. Sometimes you can get lucky and find a pin that has detached and you can solder just that one pin down as opposed to replacing the whole chip. After you have soldered in a different chip you can do the probe test just to make sure everything is connected well too.
this was a very helpful video on how to take care of those pesky chips, now I've just gotta figure out which chip I need, guess I'll start with CPU
Yeah odds are usually it’s the CPU.
It's me, Mr. Shopee!
great stuff buddy!
My childhood SNES has the same glitchy repeating pixel columns as your second unit. I initially suspected the SRAM, and I'm surprised you didn't try that. I have found which data bit between SRAM and the PPU2 is responsible for that column, by shorting each data pin to ground in turn and watching the effect on the screen. Scoping that data bit shows nothing unusual, and looking at its activity frame-to-frame it seems super consistent when displaying a static screen (FF2 start screen) that contains intermittent glitchy pixels, so I now believe it's likely PPU2 at fault and not the RAM. I was willing to attempt an SRAM swap, but the density of the PPU pins scared me, so I didn't go any further with my repair. After watching this though, maybe I'll try after all.
I am surprised you tried the CPU and PPU1 before getting to PPU2, and I'm also surprised you didn't try a PPU2 reflow before swapping.
I don’t have a scope to test logic like that and I was taking a shot in the dark with the CPU swap, usually CPU is what fails. I only reflowed the CPU at first to try it, it usually never solves the problem though. Thanks for the comment. 👍
@@PunkNDisorderlyGamer Ahh the CPU reflow - the act of desperation! I did this yesterday because I bumped my AV Famicom while in operation out of its case and killed its CPU. I could not accept this, so I reflowed the whole board in desperation. Today I was lucky to get a NES at a recycling place for $20 and performed a successful transplant. Those big chonky throughhole IC chips are a nice treat after SMT chips on the SNES.
Awesome work. Just found your channel.
Thanks👍
@@PunkNDisorderlyGamer I have been trying to repair a gpm 02 super famicom for days here myself. Black screen. All voltages good, caps replaced, cart slot good, removed cic and installed a super cic uigr board but still same. Must be a cpu or ppu issue. Looking at this video has given me confidence. Thanks
That music is from contra for the Nintendo entertainment system
Really good stuff. I like your workflow. One thing I like to do with cracked shells is apply a bit of epoxy to the interior side of the system. It helps reinforce it the shell. Have you ever tried de-yellowing any of these systems?
Yes I have, in fact there is a video on my channel already, episode 4. As a side note, I don’t use the cream I like to use regular peroxide it works just fine if you have a high UV level for the day. I have to revisit that a bit more in-depth one day. Also the epoxy is an idea perhaps I’ll try it out one day.
@@PunkNDisorderlyGamer I wonder if Bondo putty would work?
The music background seems to be from a Contra game from Konami.
Nice work all around. I have a seemingly almost mint looking snes with black screen. Took everything apart as you did, cleaned front and back and inside of pin connector even without seeing any corrosion anywhere... still black screen. I'm not into soldering and planning on trying to replace chips, what can I yes do to keep troubleshooting? I heard maybe my power adaptor not enough power? Maybe the sound unit can be causing issues? Maybe buy an oem pin connector off ebay ? Whats your advice ??
When you plug in some games like Mario kart or street fighter do you get a “Nintendo” screen? If so you could try replacing the SHVC sound module. But I’ve had pristine consoles have bad CPUs. In fact the ones that tend to work after cleaning them and fixing a broken trace or two are the corroded ones.
I don't get any screen on any game. In fact, if I don't clean the games we'll before testing it out, I don't even get the black screen. If like you said, it may be a chip problem, so many questions:
How much can a repair like the one you do cost? What if I can't find someone like that around me? Should I buy a soldering iron and flux and start messing around with chips??
can you swap any cpu/ppu revision with another one on any board revision or can you only replace with same or newer?
ian mcafee yes, you can replace any cpu with any revision cpu. Same for ppu1 and ppu2 keep in mind they have to be ppu1 with any other ppu1 and ppu2 with any other ppu2.
Hello. What would you recommend for the black screen? I cleaned it and it still won’t fire up. Very cool video. Subscribed!
Check out episode 42 for black screen of death I usually swap the cpu, unfortunately CPUs are pulled for donor boards.
@@PunkNDisorderlyGamer I replaced the cpu still nothing. Could it be the ppu?
@@ModernFactsDaily I have a bunch of SNES and SFC videos coming out soon. Stay tuned for those maybe they can help you out. But was the cpu working beforehand? You probably have 2 working CPUs and another bad component somewhere else on your board.
@@PunkNDisorderlyGamer thanks I got the test cart and it will run but stops at the burn in test. I’ll keep an eye out for those new videos thanks.
I have a system where games fire up just fine but sprites in the middle section of the screen are gone like in mario world I can't see mario but of you hit jump past a certain line you can see the mario sprite just fine. Do you think this could be bad vram? Backgrounds and everything else show just fine no other weird graphical glitches. BTW love your videos they are very detailed and helpful I've learned a lot.
That’s a tricky one, the VRAM is much easier to replace than the PPUs, you could definitely try to swap it first. I’ve never experienced anything like that. If the gamelogic seems to be correct just the graphics are wrong you could potentially rule out the CPU.
@@PunkNDisorderlyGamer Thanks! I'll start with the Vram and move on to the ppus I have some from a board with a dead CPU I can try.
Aylof let me know if you figure it out.
Aylof I just realized you could just swap the CPU from that unit into one of your dead CPU boards much easier job IMO.
What is that cartridge you are using?
Is it used for testing/diagnostics?
Where can I get one?
Nice Video. I try to repair my snes from my childhood soon. Where is good place to get replacement parts?
Depends on what parts you’re looking for. For passive components like capacitors and fuses you can get them on console5.com, for CPUs and PPUs, they’re not off the shelf components.
@@PunkNDisorderlyGamer Unfortunately my PAL SNES has a similiar issue like the one you repaired. I searched a bit and it's likely the PPU1 or 2. There are graphical issues that some layers aren't displayed or only partly.
But my only chance is to buy faulty boards to replace it, isn't it?
@@PunkNDisorderlyGamer In my case I think the PPU1 or 2 is broken. I have similiar graphical glitches and some layers of the snes aren't displayed properly similiar like in your picture. But getting chips from a broken SNES is kinda pricy. They're at a similiar price of a working one.
@@Phils3r yep unfortunately
Your test cart is it a repro that isn't crazy money? If so where did you get it? I need one but don't want to break the bank.
paul lanier It’s a repro I bought it off Etsy.
Nice found one for 39.99 www.ocdreproductions.com/Burn-In_Test_Cart/p1560736_18499139.aspx
Need help with an issue - Just recently replaced/soldered a new power port (old skool) for my Super Nintendo. After I did this, it erased all my saved data on Super Mario World and Super Mario All-Stars. Both batteries in both cartridges are fine - this issue only starting happening after I replaced the power port. Thanks for any help!
Years ago, I found a guy in youtube who say where to buy ic's for SNES console, while other states there can be only gotten from PCB donors.
I am pretty sure you have dig on it a lot. May you tell me if there is a vendor of compatible IC's Processor. etc.
I have a PAL SNES which is in a pretty good condition, except that mode 7 started to mess up... I will try cleaning it but I suspect it might be PPU dying
Yeah that’s usually the case.
@@PunkNDisorderlyGamer is 70% alcohol safe to spray liberally over the mobo? there are some flux remnants from a repair over 20 years ago, which I would like to clean before doing anything else
Hey man. On super Mario kart. All the characters ( Mario , peach , Luigi , toad etc etc ) has vertical lines on it. But within the character… not outside. What could be please ?
And also , on street fighter , the fighters shadows , on the floor , shows vertical lines as well. THANK YOU DOR YOUR HELP
That’s probably a PPU1 or PPU2 or possibly a broken trace.
I have a 1990. and if it doesnt give me a black screen, then it gives me this static of green red and black in an organized fashion. What would you recommend?
Tyler Schrand I’m not sure I’ve never seen that before. Sorry.
@@PunkNDisorderlyGamer damn. but do you have any CPUs or PPUs for purchace?
Do you find the reflow ever fixed the problem? I have a few snes that I think the CPU's are bad on. Just wondering if they may need to be reflowed
john Guido it usually never helps tbh.
@@PunkNDisorderlyGamer Ahh thanks for the heads up. I might try it on one just for giggles. Got no spare PPU's or CPU's sadly.
Check out my super famicom series they may help you out. Super famicoms are the same hardware as ntsc Super Nintendo’s. I’ve had distortion and it was due to bad caps.
@@PunkNDisorderlyGamer Ill def check them out. Love watching repair vids. These ones just give me black screens, even after complete cleanings.
What temp do you set your hot air too for doing chips? I have one and wanted to start trying chip swapping just didn't want to fry anything.
300 Celsius with full speed
Thanks I was gonna start at like 650°F which is like 340°C. Could of destroyed a chip or 5.
paul lanier that shouldn’t be too harsh just be careful of the other surrounding components.
@@PunkNDisorderlyGamer when swapping out chips do all the numbers and letters need to be Identical or just the top row? For example can I swap a chips if the first 2 rows match? I can't find any matching chips where all 3 rows match in my stock of boards. Or can I swap any ppu2 A with another ppu2 A?
@@PunkNDisorderlyGamer already bricked a board while cleaning it I tore a pad off and there's no trace to follow. I tried using an ohm meter to try to track it down on a different board but was in successfully. Know where I can get schematics on which pin goes where on different boards for the cpu?
You need some good solder wick my man
What does the V224/V239 failing indicate? I have one that came in doing that, recapped it, no change…. All the other preliminary tests passed.
I’m not sure what all the faults correspond to, do games play? Any graphic glitches?
@@PunkNDisorderlyGamer Game logic works, but graphic glitches and no music (just a small amount of distorting audio). For Example, Tetris/Dr Mario title screen almost normal, but little graphic errors of letters showing up here and there. Level select menu almost unusable. But you can navigate through games, so I am not certain it is CPU. It’s very strange.
I also have one that passes all tests but still shows faint white bars in the background layer, like a failing PPU. Sometimes they are real mysteries.
@@mercurialgirl yeah seems like a bad chip, I couldn’t tell you which one exactly.
Where you get the snes test cart from? Legit? Reproduction? I'm interested in getting one
www.ocdreproductions.com/BurnIn_Test_Cart/p1560736_18499139.aspx
Where can I get the ppu1 and ppu2 ic chips at?
Are you able to do this without magnification?
Yes
Question to anyone that may know. I tried to change the cpu and the ppu1 in a snes unit and I know the chips are good. When I switched on the unit after I soldered the new chips the unit was working fine for 7-10 mins and then it died. The pictures was distorted and then black screen. I let it cool down and switched it on again. Now it was fine for about a minute and then black screen again. The third time I switched it on it immediately projected black screen. Does anyone know why???
I think this just happened to me after reflowing the solder on the chips. I think there's a solder bridge somewhere on the pins of the chip. I don't know if it's ruined or not. Maybe Punk can tell us.
Try cleaning the cart and the cart slot, it’s strange that it would work for a few minutes and then stop all together. Also, don’t forget the sound module if you’re working on an early board revision.
@@inputfunny it’s probably not ruined just recheck your work. Also, try cleaning the cart and the cart slot.
@@PunkNDisorderlyGamer
Thanks for your reply. I have taken the unit completely apart and cleaned it thoroughly with 91% IPA especially the cart slot. I could try it again. No sound module in the unit I’m working on. It’s a pal version and have not come across to units with sound module.
Btw thanks for your video it helped me to trace what was wrong with the SNES to begin with.
@@PunkNDisorderlyGamer Thanks.
I'm having a weird problem with my childhood SNES. It randomly acts like the start button has been pressed mid game even though I hadn't touched it. I'm using 2 first party controllers that work fine on another SNES I have, I've swapped out the controller ports (including ribbon) and it still does it. Have you ever seen this before? And if so, is there any info you could give me on how to track down and fix the problem?
A faulty CPU will sometimes press buttons especially the start and shoulder buttons. I’ve had that issue in the past. It’s been so long since I’ve repaired these consoles, I’m not sure if I uploaded any fix similar to yours to my channel.
www.projectvb.com/nss/logs.htm#cpu_fail
Check Misc CPU failures, some of them include multiple buttons being registered. Very similar to what you’re describing.
@@PunkNDisorderlyGamerthank you for your response. A failed CPU is what I was afraid of but it does seem like the most likely culprit at this point. It is one of the newer 1994 models without the big metal sound block in the back which means it has a CPU B but from watching this video here it looks like CPU A and CPU B are interchangeable?
@@ChewyChicken589 yeah all CPUs are interchangeable, I’ve personally never had a bad CPU-B, not saying they don’t go bad buts more rare. Check to make sure it’s CPU-A or B, it’s probably an A.
@@PunkNDisorderlyGamer I just checked it yesterday and it's definitely a CPU b. I think it may have been fried when I foolishly used an aftermarket power block that I don't think was 100% compatible. I have since learned my lesson and bought a genuine Nintendo power block but that's what I think it may have been
Where do you learn how to made these chip swaps?
I self taught myself, it’s not perfect but it works for me.
@@PunkNDisorderlyGamer Here where i live it's hard to learn that kind of stuff, mainly because people refuse to work with old hardware. There is no one that can fix my snes, so i think i'll have to learn by myself how to do it.
Yuri Rocha I’m not sure where you live but perhaps consider buying another SNES it may be cheap option. To find replacement chips you have to pull them from another SNES anyway.
@@PunkNDisorderlyGamer i guess you're right
Yuri Rocha what’s your snes doing? Are you sure it’s a bad chip? I have 3 videos of me fixing super famicoms, it’s the same architecture so the repairs are universal, watch those three parts perhaps you can find a similar fault and it may not need a chip swap.
Oh no , my snes has those vertical lines on the left 😫 . It must be the ppu2 😭 help me
My mario kart does run good but my super Mario has small vertical lines everywhere but both have lines on the left
@@Airoria if all your games have artifacts you could have a bad PPU or CPU. Best case scenario you have a dirty cartridge connector, worse case bad PPU, worst case bad CPU.
@@PunkNDisorderlyGamer thanks yo , I cleaned the cartridge so I think it’s the ppu 😫
@@Airoria shoot me an email, I could try and help you out. Punkanddisorderlygamer@gmail.com
I sent you an email. thank you so much@@PunkNDisorderlyGamer
If you want some advice for my fellow video game repair man if you're gonna fix it why don't you go all the way and retro brighted as well that's what I do with all the systems that come my way that people want me to fix then are yellowed
Check out episode 45 👍
Retrobright doesn't repair anything and it doesn't last. Infact, sometimes is makes the already weakened Plastic weaker. With the SNES, you are usually better off leaving well enough alone or doing a case swap. I'd never try to sell a Retrobrighted Console w/o disclosing this.
It's worth saving 2 super Nintendo entertainment systems
Yes
My super nintendo is doing the same thing do you sell those chips
I would like to buy a snes 001 cpu and ppu 1 and ppu2
Unfortunately no I don’t have any for sale. These chips are proprietary chips from Nintendo and aren’t commercially available I take them from parts units and I don’t have many on hand, in fact I don’t have any CPUs on hand at all at the moment.
What’s your snes doing specifically? It may be cheaper to buy a new console and sell yours for parts.
It won't load Legend of Zelda but it will load basket ball
James Sowles is the basketball game running correctly? Perhaps the Zelda game needs to be cleaned, I would open up the Zelda game and try to scrub the pins with some Brasso. After the Brasso I would follow it up with some alcohol and try to see if the game loads.
I use some ipa on a q tip and opened up the cartridge and it looks perfect. Basketball seems to work fine tho one time when i put it in the game was running really fast players moving really fast
I fixed six Nintendo entertainment systems 2 original Nintendo gameboys 6 super Nintendo entertainment systems 2 super famicoms dozens of o g Xboxes Xbox 360 arcade slim and e
Hello dear PunkNDisorderlyGamer, I watch all your videos, you are an excellent professional, congratulations. My name is Roger I live in Brazil, I have many SNES to recover, many motherboards would you have any material where I could study and learn to repair these motherboards? Could you give me some tips?
