Title: Famicom Circuit board help!
Post by: petik1 on September 12, 2009, 06:01:46 am
hey guys I just wnated to make sure my famicom will work. I opened it up and saw that where the AC plug goes, it is just a little thing for the plug, then on the flip side of that circuit board, there are wires on the bottom of where it is going to this little gold colored thing. My question is, is this the original circuit board, and will it work? If so, how does it get the power? Thanks in advance!

We meant here.  There are usually lots of results for any one name on Facebook.  It'd be more of a convenience if you posted them here.  Just upload them to a site like Photobucket or TinyPic, get the URL, and put it in between

sorry, I didn't have a real camera working at home so I took the pics from my friends DSi. I have a link to the album though... [http://www.facebook.com/album.php?aid=6558&id=100000044554777&l=0aa98d9296 (http://www.facebook.com/album.php?aid=6558&id=100000044554777&l=0aa98d9296)

No, it's just exceptionally dirty.

That mess of wires and the "gold thing" seem to be a replacement voltage regulator that somebody soldered on instead of the onboard one.

Other than that, can you see any other mods or anything wrong? ???

I actually have 2 Famicom replacement boards that are fully working if you need one.

Asking $35 + ship for one.

Thanks

Wait, does that mean the previous owner took out the LM7805 and replacit with this? I looked at it, and it is marked HA 17805. And could you tell me anything about cleaning circuit boards properly?

Indeed, my good sir.

A can of compressed air and a soft brush will do.

Thanks! The guy you sold me this is starting to get sketchy. I asked him if he made any modifications to the system, but he told me it was the original. But as you can tell from the pictures, he replaced the regulator and the RF out.  :-\

There's also a chance he got it this way from another seller.
