I have a burn in cartridge... most games have a black screen... a couple load the opening text, but then goes black like the rest... The burn in test cartridge works correctly on my good SNES consoles, but in my broken one, the menu opens, the clock ticks down, i got the burn in test to run, all pass except the APU
@@woogieboboogie Nah. I'm pretty sure one of the sound chips are bad because the burn in cartridge says the audio processing unit is bad, and on my particular SNES there are two chips. My guess is one of those chips needs to be replaced but I would mostly be taking a shot in the dark at this point as to which one without better test equipment. I also didn't swap out the chips just yet because I didn't have the tools or soldering skills at the time to do it safely. I could probably do it now though since I have both. I am thinking I should get some better diagnostic equipment so I can determine for certain what the culprit is.
I had a 1-chip believe it or not with a bad RGB signal, I don’t have an oscilloscope so I don’t know for sure which color the color seemed yellow tinted (perhaps blue was bad) it also had a bad RGB encoder. I should have the video of that repair up next week, I got other repairs to edit before that.
@@LIRetroGaming tell me about it, I pulled the large chip from a snes jr that I already was using for parts. I previously pulled APU chip to save a 1-chip that had a black screen. The junior doesn’t have the little post in the power port so I couldn’t sell it like that, and as far as I know they don’t sell a replacement for the junior.
Yes I think you are correct that there is no third-party replacement for that power port on the junior. Hopefully someone designs a 3-D print for that at some point!
The test shorting across between green and blue was the real tell-tale sign that it was that particular chip. If it was something on the line pulling that line low it wouldn't have shown blue in the green when doing that, and instead would have made the green disappear while doing that.
I wish that I had shown the shorting a little better in the video but at least it’s visible when I started to probe the lines with the oscilloscope. It was definitely tricky to film because I didn’t really have adequate lighting
I came here because a SNES I bought has a yellowish tint for every game. I knew the plastic shells would yellow, I didn't know the display would yellow >_< This was super helpful! I'm not sure I am ready to crack open the SNES to try and fix it. But I subscribed so I can learn more about repairs. Thanks!
My friend. Everytime i replace cpu, ppu or any ic, it seems short circuit or smoke from ic i replaced. I test all pins if it has continuity. I dont know how i can swap an ic
Great! I have another problem, I do not display the back picture, those Mario runs the front pictures are present, but there is no background.. what do you think it might be?
It's really sad to think about all those SNESes (and all other retro consoles and computers) that went to "recycling" with so many useful parts still in them. Maybe one day we'll be able to make chips just like some parts can be 3d-printed today, or custom PCBs that now can be ordered for cheap or machined at home.
I need to use my microscope to do the soldering and it does not have an attachment so that I can film at the same time. I’m not sure how the blue got damaged but I assume that some component within the chip failed over time
@@LIRetroGaming that’s pretty interesting, maybe the chip’s blue color did get damaged trough heat overtime over the years,and since nintendo’s consoles never had any heat conductors on those chips itself, i would be not surprise if those chips do suffer freat heat overtime, remember how warm those cartride connectors will can get after playing a long time? Also if you open those old console you may find some crumble parts of those chips wich may be not only cause by heat but also by the extreme hard work those chips had to perform overtime, remember that no matter how tiny those transistors are, they still had to switch back and forth from one place to the next ,and i will not surprise if such motion inside those chip will cause heat overtime,it’s magic what they do in front of our eyes without any notice whether it’s generating graphics,sound or register our control presses,just woow.
Have you ever had a SNES that had random button inputs? I have one that has screwy graphics in some places and random button inputs. My gut says it has to be the CPU going bad (early onset dementia), but I also have a Mega Drive that's always holding start too. I've never seen anyone else who had this issue.
Have you confirmed that it’s not the controllers? If it’s the console then you can follow the schematics on the console5 tech wiki. I think the cpu ultimately handles controller inputs
Super informative, I like that you showed us your thinking process along with the schematic, I'm starting to learn basic electronic repairs and schematics look terrifying to me!
Huh, didn't think I'd get recommended a shvc repair. Mine's not got the color problem, the burn in cart's got sprites being left-right jittery, the the princess fine, up until the last frame, where she's missing every other vertical piece of herself, and the scrolling level bit keeps crashing and restarting. It'd be nice if some place had working PPU's, etc for sale
That sounds more like a cpu problem than a PPU problem. But unfortunately the only source for these chips right now is from other boards that have different types of damage. I really hope that someday an FPGA replacement chip could be developed. That would fix a lot of SNES with this problem
Hi there great video, you have a lot of useful tools for that work. I recently saw the problem with mine PAL SNES. In DKC 1, I have background colours off but only in some backgrounds, not all of them and only in that game. Do you have any clues how to narrow that problem?
I'm having issues with my SNES locking up video within certain seconds or after leaving a game menu but music is playing. What would cause this and how would you troubleshoot this?
very good video. i have a smiliar problem, and i now have what to do for test. i changed the quarz cristal thinking he do the problem, but that change dont fix the problem (slow lost color until gets b/w video)
I dunno if this comment is gonna be seen but, i have a snes that the rf output looks clean and when i connect the rca video, the images is a little darker and sometimes goes like glitching. Do you know which can be the damaged part?
I have a SNES where the expansion audio left channel pin doesn't output any sound. So, it means I do not get stereo sound with the Super Gameboy or SD2SNES's MSU-1. I only get sound out of the right channel. Sound/music directly from the SPC700 is still stereo and goes through both channels. Think this is something you're able to fix?
Nice vid, do you know if there are possible wram chips on the market to switch the old ones out? I have a problem with specific games (SOM, SOE) that will Boot but have problems like no key input works or black screen after first initial screen
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?
Hi I have a snes that has power but no video , any suggestions? Do you have a place to send in for repair. Local place has no idea how to fix because they said they normally don’t work on snes
Great video. I’m curious, would it be theoretically possible to diagnose and repair PPU2 itself? If not by you, could *someone* repair a microprocessor like this in theory, like if given unlimited resources? Or are they dead once they’ve failed? I’m a hardware noob so forgive me if this is a dumb question 😅
No worries, it’s a good question. All of the logic elements inside a chip are permanently etched when the chip is created. Once an element fails, I don’t believe that there is any way to repair it. Although it certainly would be awesome if that was possible!
I did the burn in test and I think I need to replace the CPU and PPU but I cant find anywhere selling these chips online? where do you buy the replacement chips?
Unfortunately they are not available. The only other place to get them is from a donor super Nintendo. I got mine from one that had water damage - The chips were fine but the circuitboard was ruined from the water
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 have a SNES with no audio/video. I replaced the fuse (it blew) but I'm not 100% sure where else I can test. Good RCA, good game cart (tested multiple) Would you wager the PPU2 chip is the culprit here?
Capacitors are most likely to fail. Those fail all the time and will need to be recapped. Mine blew a fuse when I was trying to test it out (must've been a short). I ordered new components to recap the system, replace the blown fuse, replace the VReg (did that on my SHVC-CPU-01 board), and I ordered a pair of PPU2-C chips for both my SHVC-CPU-01 board (even though the PPU works, but are known to fail) and SNS-CPU-GPM-01 board (original smoked).

I adjusted the crystal and now have color but I don't have the color red in game and the 240p test suite is showing that I have color it's just yellow and burn in test rom didn't work for me. Would you have an idea as to what that could be?
@@LIRetroGaming well, I noticed the PPU2 was shorting and found some solder was discolored. Ended up ordering new PPU2 chips (rev C) and components to get the recap done, a new fuse, and new VReg, along with a tube of thermal compound for the VReg. Where can I find the CPU for the SNES? Donor boards on eBay all have unreliable CPUs that are not revision B.
The only way to get one of those replacement chips is to extract it from another Super Nintendo that is broken. Hopefully someday a replacement can be made so that you don’t have to extract these chips from other SNES
This is true, it just takes much more work to get rid of the solder paste. Like I said solder paste is perfectly fine to do use but I have my preferences
Great video, but I don't get why you're using ChipQuik I always thought it was just when you're de-soldering chips with a soldering iron In my experience when using hot air chips can be easily de-soldered without ChipQuick or flux (I've seen some people using flux before applying hot air). With double-sided PCB like the one used in SNES the danger of using hot air is that parts on the other side will start falling off if you heat the PCB up too much, but I think there are a few ways of avoiding it. Like using the right temperature for shortest time possible, or placing the board on the wet towel (so that the towel cools down the other side of PCB). Older electronics doesn't need high temperature when unsoldering parts because it uses lead-based solder. Soldering the chip back with solder paste and hot air probably would be easier as well, than doing it pin-by-pin with the iron.
That technique you describe is also perfectly good. I just like chipquik because it’s fast and easy to clean up. I don’t have to worry about excessive heat affecting other components as well. But both methods I think are perfectly fine, I just really a matter of personal preference
Watched the whole video and read the comments, don’t know why so many are trippin so hard on hands being in the way. This is basic stuff, read schematic, probe pins to get your result. Profit.
It’s called the sd2snes and it lets you play any snes rom. I was using the official snes test rom that was used by Nintendo. It’s called the snes burn in test

Great video, but I don't get why you're using ChipQuik
I always thought it was just when you're de-soldering chips with a soldering iron
In my experience when using hot air chips can be easily de-soldered without ChipQuick or flux (I've seen some people using flux before applying hot air).
With double-sided PCB like the one used in SNES the danger of using hot air is that parts on the other side will start falling off if you heat the PCB up too much, but I think there are a few ways of avoiding it. Like using the right temperature for shortest time possible, or placing the board on the wet towel (so that the towel cools down the other side of PCB).
Older electronics doesn't need high temperature when unsoldering parts because it uses lead-based solder.
Soldering the chip back with solder paste and hot air probably would be easier as well, than doing it pin-by-pin with the iron.
That technique you describe is also perfectly good. I just like chipquik because it’s fast and easy to clean up. I don’t have to worry about excessive heat affecting other components as well. But both methods I think are perfectly fine, I just really a matter of personal preference

It’s called the sd2snes and it lets you play any snes rom. I was using the official snes test rom that was used by Nintendo. It’s called the snes burn in test
