Do not use a NES adapter, it will blow up your Famicom. (because AC and DC are very different)
But a Sega Genesis adapter would be a suitable replacement for sure.

Okay, I am an idiot...

In a hurry to try out a new FC game that required the FC port I grabbed my A/V FC and mistakenly an U.S. NES power supply and YES I used it. Or should I say attempted to.

Is my A/V FC fixable?

Thanks for any help.

So it doesn't work anymore? I'm pretty sure that AV Famicom has a fuse so check that first.

I hope something as simple as that. Problem being I REALLY know nothing about electronics.

I can and have followed instructions but calling me a novice is a complement, lol.

I put a pic of the board.

Sorry about that; I didn't mean to clog the boards.  When I got my Famicom AV last Summer, I turned it on, and white smoke started coming out!  So it clearly had the wrong power supply.  I just hope that what burned was just white plastic, and that the console still lasts for a long time. :question:

Which adapter did you use? Check the voltage regulator on the circuit board along with related circuitry. There is a large possibility your Famicom is burned out :( .

Maybe the fuse is on the other side if there is one. It will probably look something like this one http://www.mmmonkey.co.uk/blown-snes-fuse-repair/ which is for SNES.

I did some googling and someone at assembler said AV Famicom doesn't have a fuse. If it doesn't you'll probably have to replace the voltage regulator and maybe some more components like the nearby capacitors.

I heard all kinds of stories when people are using the wrong power adapter. Sometimes nothing happens at all, while other times smoke comes out.

One guy I know plugged in his friend's karaoke machine that he had brought from Japan. He wasn't thinking and plugged it in without using the step down converter (he must have used a pin adapter or something because Japanese plugs doesn't fit in Swedish outlets), then he realized what he was doing and immediately unplugged it, but smoke had already started coming out. This karaoke machine costed several thousands so he almost panicked, however it miraculously worked like normal after that when using the step down so I guess he unplugged it in time.

If you bought it and got the wrong AC adapter with it the seller should be at fault.

Hello there, i am coceting with the idea of buying famicom from Japan.
I read the first post in this topic and i THINK i understand.(but i am not sure  ;D)

So i went to e-bay and found this :
http://www.ebay.com/itm/power-supply-SMPS-Adapter-Super-Famicom-Nintendo-SNES-SFC-/321469322221?pt=FR_Jeux_Vid%C3%A9o_Jeux_de_marchandises&hash=item4ad91093ed

Is is exactly what i want for famicom in europe ?(I am from Slovakia)
Does anybody have any experiences with power supply of this sort?

Thanks.

I can't remember; I got it last summer.  I took it over to Radio Shack and they gave me a power converter that does not cause the Famicom AV to get warm at all.  It works perfectly, I just wonder HOW long it will work-in other words, did that overheating permanently damage it?  I'm hoping that the white smoke was just some of the white plastic casing that heated up; not anything that's critical to the functioning of the actual console.

Hehe, as long as the Famicom Works, nothing was damaged :).

Hmmm, it could reduce the life of that component that got heated up. But hard to say what the long term effects would be. 
A good thing is that I think that component probably could be replaced.

Do you know what PSU you used that caused this? If you can write down what is on its label, or take a photo.

It says "Input : AC 100 - 240 V (50/60Hz)" meaning it can be used in the whole world. The output says "Output : 9V DC 1000mA". Voltage is close to the Famicom's and the amperage is enough. I can't see the polarity anywhere (and I can't read Korean) but I guess it's centre negative since the seller states that it works on Famicom. Barrel size of the blue plug matches the Famicom as you can tell by the FAQ.

I've just bought an AV Famicom and terrified of blowing it up!  I'm in the UK and have a Universal adaptor, it has this on the label and I've set it to 9V:



Will it be okay?
