Sega And Nintendo Power Supply Repair Questions

My guess would be that the copper strands of the wire are broken. That's a high stress area and a reason they put the thicker plastic over the wire at that spot. If that's the problem, and you can get it open, then it could simply be a matter of pulling the the cord through the hole in the case, cutting the cord after the broken section, stripping the wires, and re-soldering them to their correct positions.

My problem is the security screws on the power supplies. Can't find a bit to fit either. Anyone know who sells them? Thanks.

I'm wondering if a large spanner bit might work on those, but I don't own one to try.



I do have a NES AC adapter that has a broken cord but I've never been bothered enough to figure this out myself.

I know what you mean. The security screw head is so different looking, never been able to find anything that even looks like it would work. Even tried the smallest pair of needlenose plyers with no luck. The Sega screw looks like a star type pattern with a very small post in the middle. I have seen 30 bit kits on various video game sale sites but don't want to waste money I don't have on something that might or might not work. Does anyone have one of those and knows if the work or not? Thanks!

Does anyone know where to get one of these and what size to get to open an NES AC Adapter? Need to get to the cord for salvage,thanks.

If you have a Harbor Freight local to you they should have it as a part of their mixed "security bit" set, shouldn't run you more than $10 out the door. Most hardware stores that sell some kind of small cheap security bit set should have that as part of the assortment.

I can get hold of tools for both nes power packs and genesis.

Do you have a dremel? It's fairly easy to make a bit like that with out of an old flathead bit. I've also heard of people having luck using the melted pen trick but I've never tried it myself. You take apart a ballpoint pen. Slightly melt the end of the tube part with a lighter. Press it onto the head of the security screw. Wait for it to harden and then unscrew. Has anyone every tried this and had it work?

I've done this a few times before and found it to work reasonably well. Tight screws will take a few tries and a pen will only be good for one or two uses.
