NES toploader problem

Post by darkslime »

Hey, I just bought a NES toploader at a garage sale, cleaned it out, and can't find any visible problems with it, but it won't work.

I opened it up and there doesn't seem to be anything wrong.

The thing just isn't turning on. I have no way to test the cables or games I've tried it with because I have no other nes.

Does anyone know common problems for the that I could try and fix?

did you actually open it and look inside? its possible that it could have internal corrosion if it wasn't kept well. If not, you're only other choice is to poke around the board with a multimeter and try to find a bad resister/capacitor/fuse etc. If there is no current going through, its resistance should be huge, somewhere in the MegaOhms or higher, if the multimeter will even read it at all. On the other hand, a fuse should read only 1 or 2 ohms and resistors should read whatever resistance they are (based on the bands).

Sorry, but I'm not exactly sure what a multimeter is. I don't know very much about this kind of stuff.

Here are pics of the board. The screws are rusted but I'm not sure how that would have an effect...

Get an inexpensive multimeter from Radio Shack (or see if someone you know has one you can borrow). The first thing I'd check is the power adapter; it could just be the NES isn't getting any juice.

You could also test this with a universal AC adapter; match the pin size, polarity, and voltage, and see if it starts. The thing is, a multimeter will be far more useful in the long run.

Well, it turns out my stepdad has a multimeter.

I put the red and black wire things on the board, and in some places the meter went up. It didn't do anything when I put it on the AC adaptor, so does that mean the AC is broken?

I put it on the symbol with the horseshoe, like this guide told me. http://www.ehow.com/how_2043011_use-mul ... n=yssp_art

If the problem is the AC, can I use the AC from any other systems for it?

Don't was to try in case it breaks it somehow.

So you plugged the AC adapter in and tested on the end that plugs into the console and got nothing?

You need a new AC adapter. A universal one should do it. Just make sure it can produce the right voltage, on the right polarity, in the right plug, with enough amperage to run it. (I don't know if the power adapter is identical to the original NES adapter.)

EDIT: Does the AC adapter output AC or DC? Did you have the meter on the right setting?

Wait, so the NES has a 850 mah 9 volt plug
And Im using a 350 mah 10 volt plug

I found an old laptop plug and used that, and it works.

Thanks everyone. :D

Now I have another problem. When I load games I have to push them backwards while I start it or it will just come up as a blue screen.

I tried it with yoshi's cookie, which is making me push back on it only when I power it up, then it plays fine, but with SMB3, I have to keep the cart pushed back the whole time I'm playing or it freezes...

How do I fix this?

I doubt it. That adapter doesn't push enough amperage.

My Sega Genesis had the same problem. You have to take a thick sewing needle and bend the cart slot contacts back out.

Whoa, whoa... Isn't laptop adaptors push a hell of a lot of power? You may blow your NES!

The laptop plug I have says:

INPUT: 100-240 V ~ 2.0A(2,0A)
50-60 Hz
OUTPUT: 19 V = 6.3A(6,3A)

Is that ok or will my NES blow?

19V is too much. Find one that is equal to it in plug size, type, and polarity at ratshack or something, around 9 volts. The NES can handle a ridiculous amount of voltage, but it's best to play it safe.

Ok, I'll look at radioshack tomorrow.

Hopefully I can fix the connectors.
