View Full Version : Nintendo repair/72 pin connectors....

01-19-2003, 04:08 PM
Well, the local game store wants me to fix their toaster NES systems. They gave me one to fiddle with to see if I could get it working. My question is about the 72 pin connectors. What exactly goes wrong with them to make them need replacing? Could one FIX them instead of replacing them? If not, does Radio Shack carry em at all or do I have to go thru MCM to get em?

Im not sure if you can FIX them other then cleaning them. I have tried Radio shack and they don't have them. You can go through MCM or sellers on Ebay, but I would reccomend MCM if you are ording quite a few. Also let me know if you are going to order from MCM as I would still be intrested in doing a Joint order (cheaper on both of us for shipping)

I recommend MCM also, the pin connectors are only $5.99 each.

What goes wrong with them is the pins are bent down and don't come back up. Therefore no connection is made to the game. I fixed my nes connecter and it works great every time. Here is the link I used to bend the pins back to make a better connection.

I've successfully fixed some pins, and replaced others.

"Fixing" only works on 'some' pins, and is time consuming, and therefore sometimes fruitless for your efforts.

Replacing works every time, and is way faster. I don't fix any more. I do systems for stores, and fixingthe old pins is not cost effective. Too many failures vs the time used.

This is my experience anyway, based on more than 20 (so far) refurbished toaster NES's.

Well, since I don't have any connectors yet, I tried fixing. The Nintendo that wouldn't work at all now sorta works and takes about 6-8 tries to seat the cart properly, thus proving that the 72 pin connector is what's wrong. It'd be too much of a hassle to fiddle with the old connectors over and over though. If they want me to start doing them, I'll start buying connectors. Thanks for all the info everyone! :)

There are 3 main reasons why they become ineffective. The first is the original connectors placed by nintendo in the NES would corrode and nearly rust making it impossible for the connection (if you look at one, sometimes the pins will be green like a copper penny). The connectors from MCM are made from a different metal alloy that nearly prevents this from happening. Second is "gunk" buildup from your cartridges transfer to the connector, therefore no connection again. The last reason is the connectors pins will eventually become "loose" (the game slides in the NES way too easy. This happens to heavily used NES's) therefore, no solid connection........not working. That is what I have come up with in my years of fixing NES's for friends and family. Make sure you clean ALL of your games thoroughly after you replace the pin connector, then you should be all set.

I would HIGHLY recommend replacement over repair of them. Trying to repair them is pretty much a waste of time, but it could be worth a try if they are just filled with gunk. Those are my thoughts. Hope it helps.
