Hey there I love your videos I watched them all. Idk why you stopped posting but don’t just do it if it brings you joy as they do to me. Stay safe and happy. Gj.
@@marcinmaliszczak9940 thanks again, Saturday I’ll post an update for everyone.
@@PunkNDisorderlyGamerthanks for all The Work
Hey bro this is exactly what is happening with my SNES, I was sure it was PPU1 and you confirmed it. Thank you so much for the clarification. I just wish I had the tools and skills to do the replacement myself.
I’m new to the channel and glad you’re active again. Hope everyone is doing well.
@@jeremyf1901 hello, welcome to the channel. 👍
2 Videos in 1 week Man Im glad your making Videos Again...
Man your work really is great.
Months ago I repaired an SNES, also reading the page you mention about errors.
let's go for more.
@@Cheloster absolutely. 👍
Man I’m glad to see your back I’ve been watching your videos for a few years and was One of the first channels I watched when I started wanting to repair things and I’ve been looking for videos from you for the past year glad you’re back at it thank you
@@joehylton464 thanks again, hope my videos helped.
Eyy! It's been too long! Nice to see you again!
@@FluffyTheGryphon it’s been a cool what? Two years? 🥴
But I’m back again 👍
Cool to see you post so recently! I’m troubleshooting my childhood snes right now with weird issues (which I may have caused). I’m hoping I can find a solution! I recapped my system and now it boots the first game, but if I turn it off then back on I get black signal. Then If I turn it off and wait for 20 min or so then back on, the game will work.
Actually, if anyone else happens to read this and may have a suggestion I’m very appreciative of any advice. Gonna recap the whole thing again and see if I damaged one on install.
Sorry to bombard w questions, I’m gonna go back through your catalogue and watch more of your vids for ideas, thanks!
@@-RTC- that’s pretty common, if you cycle the power switch too fast the game won’t boot, I think my tv won’t recognize the snes tv signal if I cycle too fast. That doesn’t sound like bad capacitors to me, I would clean the cartridge connector and the games really well, also perhaps your 7805 voltage regulator might be faulty (although this isn’t common).
@@PunkNDisorderlyGamer wow thank you for the response! The strange thing is that it didn’t do this before I recapped. If I play the first game (can be any time, it doesn’t crash during this first boot) then turn it off get another game and boot it, it just doesn’t work. I did clean the top section of the cartridge slot but I didn’t remove the slot and clean the internal pins, I will do exactly what you are recommending and thoroughly clean that in addition to ordering a voltage regulator and will replace that as well if the issue isn’t resolved. Truly appreciate you taking the time to respond.
glad to see you doing videos again :) currently working on some og Playstation atm
@@SparksNZeros that’s great hope all is going well. I should be back for a while. Stay tuned Saturday I’ll make a video with a few updates to my channel.
@@PunkNDisorderlyGamer looking forward to it, also soda spills clean up super easy with baby wipes or just vinegar and soapy water to wash the whole board off :)
Yay... Finally new SNES repair videos! I really enjoy watching your content and find what you do here very informative, please keep it up. 👍
Keep them coming!
Welcome back friend we missed you and you’re retro console repairs
Hey, guy.. I love and learn so much with your maintenance videos (the best in TH-cam). Thank you and greetings from Brazil.
@@fernandojosedossantos1244 thank you 👍
So heres some tips I've learned from my soldering experiences, Rosin the darker it is the more sticker it is. It comes in different grades the lighter is the harder it is but easier to clean. To breakdown rosin you would need something essential like a orange oil it cuts through it. I have a special bottle mixed with 99% ipa and citra solv. Sometimes I used the citra solv first with a q-tip to cut out all of the rosin and then clean with the ipa. The MG chemicals stuff is good but it leaves a mess and flux no matter how its made either tacky or liquid is much easier to clean off while it's hot. I use cleanroom wipes which are lint free and don't leave any fuzz the same with the swabs lint free are the best. Granted its a little more expensive but it makes everything better. Rosin is the best when it comes to soldering because because it cleans off the impurities from the metal and solder is attracts to it. The synthetic stuff like MG chemicals is good because they can make it stronger plus tackier which helps hold components into place when using an oven. I use a company called stirri they make some awesome stuff you should give them a try one day.
@@rubenmejia4881 that’s great advice. I’ll check out stirri.
Thanks for this video and going through the entire process. I have a GPM-02 that I recapped last year that seemed to be working great. The recap went well and everything worked fine in testing without the burn-in cartridge to verify. After doing a deep clean of all the flux residue though the console would not post. Not even into the burn-in cartridge. It has left console as huge mystery of what went wrong. It has a CPU B and testing with an oscilloscope it seems to have signs of life though. It is now making me wonder if the problem is more likely PPU-2 or something else related. I do not have extra parts to give it a try, but one day I would like to revive this console.
❤
I have same problem with my super famicom
Yeah these chips tend to die over time.
Mine had the same problem 🎉 I fixed it already 🎉❤
Hello! Congratulations on the videos, I see that you know the super Nintendo very well, I would like to ask you about a super 1chip that does not provide audio, you can only hear a hum... I have taken the test and it passed. I have renewed the capacitors and cleaned the slot, but the problem persists. I would appreciate it if you advise me what to review or replace... thank you very much.
@@robertbermudezblanco9230 my guess is a bad APU chip (they do fail) but, I wouldn’t attempt to remove that chip with heat, for some reason (in my experience) sound chips don’t withstand heat like the other chips. Also, it could be a bad U6 or U10 chip, (but this is just a guess). If I knew how to use an Oscope I’d probe the audio signal and just trace it back using the schematics.
@@PunkNDisorderlyGamer Thank you very much for the answer! I think I'll start trying my luck with U6 and U10, which seem easier to remove and solder.
I think the chips need some sort of cooling like a small heatsink or something. That is my theory. I am currently working on a couple snes consoles and when I get one of them up and going I want to try and come up with some sort of stick on heatsink solution to try and make the chips last longer. The console also has zero heat vents for air flow. I dont want to cut my shell but am thinking about sourcing some small heat sinks like similar to what can be used on a raspberry pi4. Do you think the heat is what is killing these chips?
@@DoodMang7 I suppose you could wire a fan to the power switch to circulate some air if you wanted to.
And you have to use water on soda and sugary liquids alcohol will not remove them
@@joehylton464 yeah the soda was being super stubborn. Next time I’ll wash it with dish soap and water, that usually does the trick with sticky substances.
Have you ever removed one of the newer, non detachable cartridge slots that's just soldered straight in? And if so, is there any special trick or something to removing these or do you just desolder the pins and pull it out?
@@ChewyChicken589 the last few revisions of the SNES, the cartridge connector is soldered to the board, you have to desolder them.
@@PunkNDisorderlyGamer yeah, that's what I was thinking. I was just wondering if it was glued down or something. Thank you
@@PunkNDisorderlyGamer and they do actually make flux cleaner/remover, it's mostly the same as nail polish remover. I'm not sure what the difference is if any, maybe nail polish remover has some scents in it or something
@@ChewyChicken589 nail polish remover is usually acetone.
@@PunkNDisorderlyGamer yeah, that's basically what it is
You should have a test snes console with sockets to easily test chips
@@choppert6 I was looking into it a few years ago, but they were incredibly expensive so I passed.
Long time bro hope all is well with you
@@rishiramdial3435 everything is great. Thanks 👍
What do i do if my burn in test cart wont load? What is the likely cause?
@@dylanhaataja3858 either a dirty cart connector, corrosion damage on the board, or a bad chip (probably the CPU).
Try water on the soda damaged board! I had a game boy cart loaded with dry soda! IPA wouldn’t budge it! With water it came right off! Was Surprised
Where do you find the snes’s that are for parts/repair because the BS that I am seeing is they want $40+shipping for a non working console and that is asinine if you are going to spend $120 for the parts to make a working console then just buy one that is working in the first place.
@@outlawphil I got all these consoles from a local game store they had a box of broken boards. As for SNES parts your best bet is to buy Super Famicoms as they’re much cheaper and the chips are compatible.
I have a 1 chip 03 board that I lost sound on it. I tried swapping caps and s mix chip and still no sound. Can I send this your way and see if you can make it work and make a video on it? A fee as well of coarse. Thanks.
Sorry at the moment I can’t take on any projects. Perhaps in the near future I would be interested. Plus a console with no sound, sounds like a bad APU chip, and unfortunately I don’t have any spare apu chips on hand.
@@PunkNDisorderlyGamer I understand. Thanks for the response. APU chip can be scavenged from any snes right? doesn't need to be the exact same model board?
@@Mo7-7 an APU on a 1 chip board is a single chip that was consolidated from 2 chips in the early revisions. Much like the CPUs and PPUs combined into 1 chip, they also combined the Audio chips into 1 chip. The only boards that use the same APU chip are of course all the 1chip revisions, the snes junior, and the snes APU board revision right before they released the 1chip-01. Hope this helps, if you do plan on removing the APU chip I don’t suggest hot air, try chip quik instead.
@@PunkNDisorderlyGamer Wow thank you for the knowledge. I appreciate you sharing that information right as I am browsing ebay looking for a apu chip. I will take your advice on chip quick instead of hot air. I will follow up with results once I get a a hold of an apu chip. Looks like the only thing on ebay is a 44.99 cpu-01 motherboard right now.
@@Mo7-7 here’s a tip if you find a late un29 serial number or even a early un30 you will most likely get an snes APU board revision. But you could also try and find a broken snes junior.
the king is back
omg i have the same problem. i have a sns-cpu-gpm-02 cpu-b. similar garbage from donkey kong country. the burn in test was also similar. I just need a ppu 1...
hello,my 1chip snes service card display vram low , U5 vram bad or 1chip bad ?
It could be a bad connection between the 2 chips probably a break from corrosion somewhere. Do you have pictures of the board? If you have discord post them in my discord and maybe we can help you.
I missed your videos in Russia. Why did you disappear for so long? Did you get yourself a girlfriend?
@@ZolotarevAleksandr haha no, I didn’t feel like doing videos.
