Hey i just want to take a second to thank you for this video. Much like you, i used my NES power supply on a Famicom like an idiot and broke it. I saw you video, went to a small electronics shop, bought the 3 parts (fuse, cap and 7805) and now my Famicom is as good as new!!! :) There is a good chance that replacing the fuse alone would have worked in my case, but given that a a new cap + 7805 was like 1.50$, i figure I would do it like you.
Great video! I bought a Famicom from Japan as junk. I can't get it to power on, but it has the 1983/1984 boards. Apparently these older boards didn't have a fuse anywhere that I can see. I got it cheap, so I guess I will sell it cheap and try to find another one.
hi friend. i have a question, because the inside of my famicom is a little bit different, and I'm not finding this fuse... could it be different? something is wrong with my famicom? how can i find this fuse? thanks!
In case I ever got a Famicom with defective audio/video and/or no power, I should probably replace the transistor (LM7805C), capacitors, and fuse, shouldn't I? Even if the Famicom's dead, perhaps the controller(s) could be salvaged.
The Fuse should be in the back were you power cable plugs in and your video output. There will be a simble with two straight lines with a wave between them, that will be your fuse.
I accidentally use the FC 110v power supply plug into a 220v transformer. The console fried right away. Are these the 3 fuses/chips needed to be replaced?
For what I replaced in the video it did fix it. 1 fuse, 1 cap, and a Transistor. If this model is the same as the one your working on then this repair will work.
Did you open the consol and see a fuse simble like the one show in the video. If the system dosen't power on then the fuse, 6.5A cap, and the chip is gone which it's not hard to replace. Find someone who knows how to use a sodering gun and a desodering gun to replace the 3 parts. Then just get a 10v power supple, then turn to tv to ch.96.
Hi. Thanks for the video. Is there any way to test the fuse and the chip? I've just got a famicom and plugged it with a nes adapter. Not sure if something happened. I tried after with an appropriate power supply and I'm not getting any signal... Thanks
The fuse can be check with a volt meter and the transistor but the transistor is a little harder to check. Be sure to look at the cap as seen in the video and see if it is bubbled. The bubble on the cap means its blown and will need replaced.
Well...I hate to be the bearer of bad news but, you have just fried your famicom. The reason why is because the NES and the famicom use different voltages. I've heard that the adapter for a sega Genesis works with the famicom.
Well, the famicom was cooked buy my oops with the power supply being backwards but after I fix the items in the video it was working just fine. So it's not fried.
Hi. My Famicom is outputting 14vdc (it says printed on the adapter, 10v 850mA) . Is this normal? It's a 100v power supply (japan). If 14v is ok, what's the next component to check? Or should I just automatically replace all 3 components you replaced? Thank you. God bless, Proverbs 31
Hi. Would this work: Can Famicom transistor/voltage regulator (is a regulator a transistor too?) HA 17805 be replaced withI with a AN7805 (the one I bought, the only one available)? I think HA means Hitachi. Is the 1 before the 7 important? Or these are just the same 7805? By the way, off topic (about a power supply for another gadget). Also, the original ceramic fuse had a label of T8AH250V will the one I bought work (it's the only 250v available)? : 5A BS1362 6X30 Besides the amperage what do the other numbers even mean? Also, I bought a fuse but it's the glass one only 1.5A- would this work? If that's ok, how thick/gauge should the wires for the legs be? Thanks.
@@SevenDeMagnus The transistor you have HA 17805 mite work, it's a 1.0 amp and the LM7805C is a 1.5 amp V.R. \ Voltage Regulator act like a Light switch and a Transited acts like two diodes tied together ether as a NPN OR PNP (Positive or Negative). For the LM7805C I get 11 listing on Ebay in the US. and there is One listing I seen thats from France.
Thank again sir. By the way if the fuse in the Famicom is 1.5A, I only got to buy the big glass one at our only subcomponent electronics store in the country, what gauge wire/how thick should the legs be, that'll be soldered to the board?
@@SevenDeMagnus The gauge wire for the fuse is a 20 gauge. The full size glass fuse won't work, they usually don't have wire leads but once with leads are manly 14 gauge wire which is to big and it will fry your system. Try to find a 125v 1.5 amp Pico fuse and that will work.
Hey, This seem to be the only vid i can find that actually repairs a famicom.I do not consider cleaning a system as a repair. I do know cleaning an old system can do the trick but still,One does not repair ones house every spring ;) Question, My FC "boots", i KNOW its getting info from the cart, BUT the screen is not showing other then going from complete black to random pixels with faint sound. Me thinks it needs fixing, Can you make a vid dealing with this problem? :)Long shot but worth a try
Hi sir. This is a bit off topic but it's a bit similar (problems with power). Does my Famicom power/AC adapter need rewinding or does it need it's capacitor replaced? The adapter is 10v DC but the power/AC adapter is only outputting less than 1v. The specifications are: DC 10v 850mA AC 100v 50/60Hz 18Va Is it the capacitor? The capacitor spec is 16v 2200 microFarads. Thank you in advance. God bless, Psalm 11:7
If the AC adapter is only putting out 1v ac and not 100v then i would say your transformer in the AC is bad. Are you using your Famicom out US or in the US? Once you know the power supply is good and the system still dose not come on, then it would be a bad cap and fuse which should look like the one in the video unless you have a older model.
Hi, I'm using it out the US. The Famicom power adapter is only outputting, 1 volt DC, I mean (measured at the end, the end that plugs into the Famicom). Would this need a fuse replacement (where is the fuse located), a cap replacement or needs to be rewinded? The power supply is the first batch (1983). Thanks again.
Hi. Trying to make time to repair the Famicom (for nostalgia, this was my first video game console that I have for my own by exchanging my bike, when I was 14). Would this fuse specification work. I don't need that many but it's got free shipping (shipping is expensive): www.aliexpress.com/item/32853381372.html?spm=a2g0o.cart.0.0.32e43c00X6ZpTw&mp=1 Thank you. God bless, Proverbs 31
Hi. I finally got the fuse (100 pieces, too many, lol but I'd probably sell some and give away some), that was a long wait. I've soldered it (pretty tough) but I accidentally yanked the power switch wire but I've soldered it back thank to iFixit's disassembly. The Famicom won't work still, I wonder which capacitor or resistor or transistor should I check next? This revive (including the wait for the fuse which took 2 months + the months of research) has been more than 2 years:D but perseverance. God bless, Proverbs 31
Do you have a TV that can go to Channel 95 or 96. I think it was one of these channels that the famicom only works since the Japanese TV'S use different singles to operate.
Hi. Famicom has no power. Famicom power supply only has less than 1 VDC power. I already replaced the power supply's capacitor. Any idea how to fix it? Thank you. God bless, Proverbs 31
The power supply should be putting out 9v 850 milliamps. If not then I would say the transformer in it is blown open so it can't build up 9v to power the famicom.
Yea, at least I would if that was the only problem. For the controllers, they can be saved for parts in case someone broke there famicom controller sense they can't be used on american Nintendo's because the way the input's are.
I got my famicom months ago. Japan seller sells many but I tried 120v av adapter Idk if I fried it I then complain to seller he sent 100v av adapter and a rf the one that goes with the famicom. Do you think I fried it? I can't figure out how to make it work in Canada and I had a ig collector guy try help me. @sara_colorful_nintendosegagirl it's upsetting that can't make it work
That 120v sounds like just a input for the power supply from the wall to plug. What u need to watch out for is the output amps and voltage to the famicom. The output of your power supply should be 9v 850 miliamps - 1.3 amps. If your using the power supply from japan I would not trust that sense your voltage from Japan to Canada will be different just like here in the US. I think It mite be fine as long as u did not hear a pop in the system when u pluged it in. If u did then just like in the video made u will have to replace the Fuse, the chip (voltage regulator) and the Capacitor if its bubbled at the top and leaves acid mess on the board which It need clean before it eats the motherboard.
I replaced 3 things you mentioned and I got my AV modded Famicom working again. I can't thank you enough for making this video!

nice job saving that japanese nintendo famicom
Thanks dude I fixed my famicom with this video

That's a good model Famicom, RetroGamerJapanVids made a video about the 2 different models, and this one is the better model.
I see you everywhere
@@applepretz5368 Yes you do, I'm usually the guy who gives out my thoughts let alone help others who need help troubleshooting for details.

Hey I know this video is old, but I was wondering if you knew what kind of trimmer cap is on the rf board.
The Fuse should be in the back were you power cable plugs in and your video output. There will be a simble with two straight lines with a wave between them, that will be your fuse.

For what I replaced in the video it did fix it. 1 fuse, 1 cap, and a Transistor. If this model is the same as the one your working on then this repair will work.
Sure, I can look at it and try to get it back up if it's the same model. I am located in jackson, mi.

Is it just chip that I think needs to be replaced

It should be fine with the 14 volts, if its not turning on then replace the three parts I did.
