How to fix a SNES that won't turn on - A troubleshooting guide 

Just wanted to say thank you. A comprehensive video like this is literally good as gold. I saved my SNES with your help!

Hey I just figured I'd let you know this video actually helped me where roughly 5 hours of searching for answers and watching other video tutorials failed.

Great video! Tried every part of testing it like you showed and it all worked fine. Turns out I had the same problem as yourself, just needed a good clean. Cheers.

Just wanna say even if you get continuity on the DC jack make sure you clean it out to make sure its not dirty/corroded. Checked everything on my super famicom and was ready to resort to a full recap but I decided to clean the jack for the heck of it - turns out a dirty power jack was the problem.

Good video, thanks! I appreciate how thorough you are on your explanation.

Great video! Sorted mine out using your guide. Thanks man

So my SNES won't power on and it has nothing to do with ANY of the things mentioned in this video. My problem is with T1. I thought it was with C30 and C31, but it turns out to be T1 (which isn't even labeled on my SVCH-CPU-01 board), it has "RC01" written on it. After searching for quite a while, I found that T1 is a Common Mode Choke and that part number "TDK ZJYS51R5-2P" could be used to fix it. Why is their absolutely NO VIDEOS on RU-vid about SNES repair that mention replacing T1? Not ONE!

Lots of fantastic tips there for me, thank you. I have a powerless snes at home which I'll be going over with a fine tooth comb. Subscribed

First of thanks so much you've helped alot I've found the problem is on the bottom of te board the second soldered point isn't receiving power the first is and so is the two solder points holding the pico fuse but now what do u recommend I do to finish fixing the problem?

Thank you for this overview! Would you have any recommendations as what to look for, if your super nintendo powers up (red led lights up) but there is no picture or audio from it? Thank you kindly.

Wonderful video! Great explanation on how multimeters work as well :)

Awesome very thorough and helpful

Excellent video. Thanks!

Excellent video, mate, thank you!

Hi mate. Great vid, i've isolated using my multimeter that mine has likely also blown the fuse, as im getting nothing through the meter. My question is this, I have a UK one and the fuse inside appears to be different to all the others i've seen online including yours. However all of these have been either US or in your case PAL AUS versions. Inside mine instead of the 1.5Pico fuse, I have a smaller green what appears to be a 1/2amp pico fuse? I assume this is becuase the UK outputs 240V for the mains, so perhaps a smaller fuse is required? I'm no expert on this stuff but does that make any sense or is mine been fiddled with in the past? Thanks

THXX.. Great instructional video!!! I just got a non-working SNES. It was my payment for fixing 2, NES consoles. I did this for a guy who owns a used junk type store in town. I'll see if I can get this thing resurrected!!

Great vids, thanks!

Great video. I wasn't able to find the problem. I get no power when switched on. I do have continuity through my fuse and across the switch. Also have continuity on board where the power supply connects. The power supply supplies about 9.6VDC, however once I connect it and then test the points on the board where the power supply connects I only read about 2.5VDC. I think this could be my problem but I don't have a working unit to see what the actual voltage read should be. Thanks

Thanks for the video!!

really good video, I know Im going to fix my snes now Thanks.

I'm wondering if the same applies to the Super Famicom. I recently purchased a SFC in Tokyo and it worked perfectly on Japanese a outlet. I then traveled to Hong Kong and stupidly plugged the SFC into a voltage adapter which I believe fried it... (I know dumb idea). Once I arrived back in the US I plugged SFC into a voltage step down and the console will still not turn on. I'm hoping replacing the fuse will bring her back to life. Any thoughts are welcome. Thank you for the great article,

could you put a 1.5 fuse in the power adapter cord and bypass the internal fuse? Would this accomplish the same thing?

loved this video. My SNES problem is different. if you could point me in the right direction it would be a big help. it powers on but the first image is scrambled and wont move to the title screen. i cleaned all i could as gently as possible. i've exausted all non extreme attempts. thanks!

Great vid, thanks a lot man.

Very nice video!

Does anyone know if you can use a can of CRC to clean the cartridge contacts? I've used it on old pinball machine connector blocks but there is no board anywhere near it, just pins

Hello question ,I cleaned my supernintendo and replaced pico fuse now when I plug it into tv it makes a buzzing /running noise ,what can it be

Hello i am having trouble with my super Nintendo i cant seme yo get it working i couldnt get a 1.5 fuse only 1 or 2 and i try with both but for some reason it keeps blowing them off also i could only get The type of fuse thats like a glass. Any suggestions i van get from you? Thanks

Could you please tell me where to check my snes it's only giving green and black on the output to the screen and it looks like a gameboy 🙈 I have a soldering iron and a good multimeter, which resistors could be blown up? Thank you for the video... I'll try it out on my second snes which doesn't turn on

hi retrogami.ng i left my fuse in my super nes i put in 1 amp fuse wire in will that work im from australia too

i have snes that had blown fuse, i replaced it and console powers on but i get no signal to my tv via the composit cabels, what might be the problem?

Hi, I haven't used my SNES for over 10 years I want to start playing it again, so the problem is I have up graded my new TV and now when I plug in my power plug in and swtich on the tv wont play the game am using HMD1 I have tested all other slots and nothing all connections are in right place does that mean it's broke and would I need to take it apart and find out how to fix it, thanks,

i've got a question for ya, my snes does recognize the cartridges, it even shows (for example using punch out) the nintendo logo, but it freezes there, the game won't start, i already cleant the 62 pin slot and the lower part of it, what else could i do to solve this issue?

Hi please help! I have done everything in this video, the 1.5a fuse did not have continuity, replaced it now it does. Checked continuity on everything else in this video and anything i could see. The circuit board looks very clean no mould or dust. I even tested the AC plug on a lamp, lamp didnt work, so bought a new AC adapter, nothing still. Im out of ideas :(

Do you have a video or guide that explains how to fix a SNES mini console that won't turn on or is it the same as a regular SNES?

What is it with the Pal Snes they always seem to have corrosion in the power and rf ports. The few Pal Snes I've seen all had that problem must be the weather over there

I've bought a apparently broken SNES and it should arrive in a few days, the power button and LED work but the guy told me that he doesn't get a video or audio signal on his TV, do you know what could be the problem? Would be awesome if you could help me out! :D

I will have to check this out cause I had my SNES open to clean out the 62 bit part and it worked great as I tried some games before closing it back up but the switch was touching part of the Motherboard when I switch it on and then it wouldn't come back on again...I already ordered a new switch, which is fine as they only run about $4, but now I might be thinking it's the fuse...I'll have to check it out...but it shorted out after touching something when power went through

With what can I clean my pcb board and what can I use to take out the corrosion

hello i have a black screen on snes i have a cleaned connectors to the slot cartridges but continue the black screen help please thanks

Thanks for the video. I am getting continuity all the way through even though the fuse whcih I thought was blown. The problem with my SNES is its powers up, displays the title of the game, and then goes black. Suggestions?

Thank you. Fixed my SNES.

Hello, I'm having a problem with my super nes. I gave it to my brother for a couple of weeks and when I took it back to my house I notice that no game was accepted. I just turned the snes on but there was no signal about the game. the red light turns on as always, but no game works on it. And I tried many many times but no one did. What do you think the problem may be?

Are the numbers all the same for an NTSC system?

Thanks this helped me fix my snes

nice video , hope i can fix my snes

Thanks, it was the fuse in my case!

*Thanks guy, my Snes stopped working yonks ago but never threw it out, I want to sell it but don't have a clue where to start with* *diagnosing what the hell is wrong with it.*

how do I reflow a ppu chip? my mode 7 graphics are corrupt...im a novice but when my game bit arrives i'll clean the board and chips using compressed air and isoproypal alcohol....that's the best I can do probably....any other tips to getting the mode 7 graphics up and running again? which of the 2 ppu chips will be damaged? can I use simple solder techniques?......many thanks people!!!

This is an age old tip from the 1990s, someone once taught me - just desolder that fuse and solder a single strand of stranded wire across the gap. Done :)

Can you fix snes that had short circuit?

How do you make it work on the TV? Mine turns on just, it being on channel 3 and antenna (rather than video) mine shows a black screen with thick white lines on it (like three) that will not go away. Someone help? :(

Does all the snes have a capacitor? Mine doesnt have one. But i dont look like anyone has desolider it.

mine turns without video but with sound for the first 2-3 sec then goes blank, power comes on just no video/ little bit of sound? tried with different games and got the same result. any ideas?

Supers been sitting for 15 years , plugged it in no power, found another power supply plugged it in power was like yes , but was wonky kept turning off .tried the next day red light power then off nothing. Checked for voltage on the power supplys nothing on both crazy...true story

My circuit breaker blew and I fix it with a wire. Now I've must have blown something else. :( Any solutions?!?

ummm do you know how to turn on a SNES without its power adapter im working on a project and i dont have a power source

do you now how to fix a snes mini because i have one and don't turn on

Cheers, my panic quickly turned to relief when i found the blown fuse.

I'm pretty sure you are testing the voltage incorrectly. The SNES Adapter takes in 120AC V and OUTPUTS 9-10DC V. You were testing the output as AC, although you got a reading close to the correct number, your method was wrong, you have to set the multimeter to 20 V DC.

Console5 for pico fuse

My snes will not turn on, it has the adapter and what and i would plug it in the snes and turn it on but the system will not turn on, i dont now if its the adapter input or the system and the light wont turn on, can anybody help me?

I recently bought an SNES and still don't have any games for it but when I turn it on the red LED light also turns on but nothing comes out on my TV, just the "No Signal" as if there was nothing connected, is this normal since theres no game in the system or should it still show something? i would really appreciate if someone that knows would respond.

I have a Super Nintendo the light comes on but nothing shows on the TV I thought it was the out a jack connection but it was not is anybody have a clue what's going on with it

i have two NES and one super nintendo. all wont turn on, tried all three plugs on all three consoles. so i have no clue

I had a power problem. The power brick had to be stitting on a certain side or it wouldn't work. Could be the power brick if anybody is looking for issues. Replacements are cheap on ebay.

love ya mate

Hello Sir, With your accent I can assume your australian? Can you please tell me any australian courses that would be useful to get into this kind of business? Kind Regards Scott

can you please watch my video, I have a snes motherboard with a bad chip. it's the one near the dude, I replaced the 1.5 pico fuse so I know it's not that. please ant feed back would be awesome, thank you

Any suitable power supply will work. If you need AC or DC power supply depends on the region of your console. You don't need an official Nintendo one :)

My SNES (PAL) won't play any games. It will give a red light when i start up the system, however it doesn't start up the cartridges. If i slightly pull the Cartdridge up a bit, it'll show a glitch screen. This happens with the 4 games that i have. Can somebody help me?

Thought you was gonna me 😂 lol. Never mind still liked the video

Today I cleaned my snes motherboard with 100%alcohol+soft brush and now its not turning on. What did I do wrong? Did this with zillions of consoles and phones and they were always working!

Alternatively to a Super Nintendo you can use a Nes to test power adapters

Theres like orange shit all around my fuse. Does that mean i blew it?

I suspected the fuse, looked here to locate fuse in circuit. Tested, no continuity, fuse blown. Jumped to test, unit worked...............cool Now to find a fuse.

Found loads of them fuses on ebay

Surely a SNES is DC power @ 9v !?

Legend of Zelda prepare to be played!

Replaced the Power Input and Pico fuse, Continuity in the Power switch, no power. Sad I guess I must have fried the mobo or something.....SNES' are absolute crap for these shoddy fuse problems and they all deserve to be trashed.

I start 'getting to the point' within the first minute of the video... Troubleshooting is exactly that. If you already know what you're doing, why are you watching? If you're a simple minded douchebag with the attention span of a flea, looking for a quick fix, my videos aren't for you.
