Famicom White Screen?

[evildragon]

The NES powerbrick outputs a real AC current.

The NES actually has the regulators INTERNALLY on the NES deck itself.

So, your playing dangerous using an AC NES brick on anything that requires DC.

oh my god i am gonna have to take a picture, i'll be right back
fuckin a some one killed my volt meter. tried it out on a battery, nothing. stuck it in a wall socket, nothin.
oh well i guess, my NES power brick works on my famicom and super famicom, i cam post pics of that if needed

all of these power bricks convert a AC voltage to a DC voltage japan runs roughly on 100V AC for their power system in the US its 110V but either or work with out issue.

my famicom and super famicom work in the US fine, and my NES and SNES work in japan fine. my NES power bricks work on my FC and SFC fine aswell.
the only thing i have found that doesent work is my NES pwoer brick doesent work on my TwinFamicom because it has a different plug

Dude, I've seen you post in lots of technical discussions over the years with incorrect information but haven't said anything until now. You don't seem to know much about these things, so please don't spread incorrect information.

An NES AC adapter does NOT convert AC to DC the way most video game power adapters do. The NES does that work from what I've read.

What you quoted has NOTHING to do with the 100V Japanese and 110V USA standards. We're talking AC and DC here, not voltage. AC given to a circuit expecting DC will usually tear it a new one. Yes, the power from the outlet is AC and most adapters convert it to DC so the system can use it. However an official NES AC adapter does not convert AC to DC, it passes the current right along and outputs AC. Yes, some consoles will convert it on their own, but most won't and that's where you get the popping and the smoking and the melting and the "OMG what happened to my system?!!111 PLZ help!!11"

Plugging an adapter that states it outputs AC into a system that runs on DC is a stupid idea no matter how you slice it. The assumption that if a plug fits then it must be correct is plain stupidity - such as running a JVC X'Eye with a Genesis 2 power adapter. Use caution with the NES adapter and anything that outputs AC for that matter.

EDIT: evildragon beat me to it, I need to go take a picture myself.

Here you are...



Feel free to post pictures of your smoking consoles.

Yea, if it were DC powerbricks, it would have the usual symbols like:
-C+
+C-

But being the NES brick is AC, instead you get a ~ symbol.

EDIT: Though insanedavids clearly says AC. Mine has the ~ on it.

I tried hooking it up right to the TV and I tried a couple different RF cables but none of them did anything more than the white screen.

Hey Man!...Why don't you try modding your Famicom to Composite/Audio jacks instead?....with the right electronic parts is fairly easy to do!...

I would but with no idea if the system actually works, no skills to do it and no tools I don't think it'll happen.

I bought the system untested could it be that someone before me used a wrong PSU and fried the system?

cant see what he says hes on my list.

as for the modding if i can do it any one can. its pretty old tech , most of it is though the PCB (mabe all i cant rember) instead of surface mount.

MAN, the truth hurts some people.

your joking right?

dude i have an official NES power brick here somewhere, it says 9V AC on it. the NES has a diode bridge inside to convert it to DC which is why you can use either AC or DC on it. if i use the NES ac cord on a model 1 genesis the sound will buzz, if i use the genesis power cord on the nes it runs fine
