AV Famicom help - *fixed pics*

[KalessinDB]

So. Let's just get this out of the way real fast-like:

I'm an idiot.


There, that was easy enough. So I just got my AV Famicom and SAG Deluxe Edition Everdrive N8 in the mail. Went to fire it up to start it up and, like a dummy, just grabbed my toploader NES power supply.

*sad trombone noise*

So. I'm HOPING that I just popped a fuse in it, but as I have basically zero soldering experience beyond a junior high "This is the hot end, don't touch this end" level, I have no way of testing this. Am I right? Fuse only? Or did I just kill a system with my stupidity?

And if it's just a fuse, whoooo wants to let me pay them to replace it?

*sigh*

I haven't dealt with toploaders from either region, but the original Famicom does have an easy to replace fuse. The system I got was cheap as it needed it replaced and was sold as non working. If it is just a fuse, I have some and could replace it.

[KalessinDB]

Well that's encouraging. Let me see about opening it up and snapping a picture or two.

Edit: Well damn. That sure doesn't look like a fuse. That looks like scorch marks RIGHT at where the power plug meets the board. That's significantly less encouraging. Man I feel stupid.

I can't see your picks. Could just be a fried voltage regulator.

Sorry it is too late to help, but everyone else should follow these steps:

1) Locate your NES power bricks.
2) Put them in storage where you will never be tempted to use them again.

An NES will run just fine on DC, and replacements are cheap.

[KalessinDB]

Bah. Cross posting from Dropbox is being troublesome. I'll get them uploaded somewhere else.

And yeah I really should, just some part of me really likes using original power adapters. But if I can prevent this stupidity happening again (been able to avoid it for well over a decade of collecting, but it comes for everyone eventually I guess)

Pretty sure you blew either the filter capacitor or the 7805. Thankfully both are easily replaced, you could even get both components at RadioShack if you wanted to (although it's cheaper through eBay or Mouser).

[KalessinDB]

Quick bump because I appear to have fixed the picture-linking problem.

If anyone thinks they know how to fix it (including any of the several cheap fixes floated so far) and is willing to do it for a reasonable price, please PM me.

[Duke.Togo]

The voltage regulator (probably 7805 like Apolloboy mentioned) is U7 in your pic. If it were me I would start with replacing that guy. Also, I don't see anything that looks like scorch marks.

[KalessinDB]

The underside of U7 there (which, if I'm not mistaken, says 7805 on the side of it -- I reassembled it and don't feel like stripping it down again) is where I was referring to the "scorch marks" which may have been a bit of an exaggeration. The brown discoloration there, and it seems to have bubbled slightly (which I'm aware I did not photograph well - these were quick cell phone pics).

But that being said, this is heartening in that it's likely to be an easy fix. Probably for someone else, since I would likely make it worse not better... I really need to find something to practice soldering on.

[Duke.Togo]

Maybe it looks different in person, but from the pic it just looked like flux. Should be an easy swap if you know someone decent at soldering.
