NES Nintendo Console Repair, 72 pin fix, complete tear down,

Alright today we’re going to tear down the original NES Nintendo Console. Remember this little square right here I’m going.


Alright today we’re going to tear down the
original NES Nintendo Console. Remember this little square right here I’m
going to come back and talk about it in a second, it’s actually pretty interesting. There are 6 screws along the bottom, then
the plastic top just comes up and away from the rest of the console. Then there are 4 screws along this top shield. You can lift that up and away from the console
as well. That exposes the little cartridge slot that
presses up and down in order to connect the cartridge itself with the system. There are 2 screws holding that in place. Then there’s one screw holding the rest
of the motherboard in place that you have to undo in order to lift the motherboard out
and give you enough room to take off the little cartridge holder. Now that that’s off you can kind of see
the little mechanism that it has in there to go up and down and hold it in place. Then right here at the bottom of the system
there are 2 more screws holding on the black piece of plastic that holds the controller
connectors in place. Once that’s off the controller connectors
can just pull away from the system once they’re unplugged from the main board themselves. I’m going to show you how to unplug them. These are kind of interesting connectors;
you can’t just pull them straight out. You have to actually lift up on the little
white tabs first and then wedge the green connector out and I’ll show you a little
closer right here. Just lifting it up and kind of prying it out
at the same time. Then it pulls it away from the system. Then the same thing with the blue connector. They’re in there pretty tight, especially
after 20 years or so. Just kind of pull them out. Then there’s one more shield that comes
away from the main board. Then you can see this little expansion spot
right here is what we were talking about earlier. Minnesota actually came up with a lottery
system that connected to a modem. It never actually took off but it’s pretty
interesting that someone actually did make an accessory for the NES console. Then here’s the rest of the main board. You can see right there the 72 pin connector
where the cartridges came in. There’s actually the worst part of the system. It was the most likely to fail. Luckily it’s pretty easy to swap out and
only takes probably about 2 minutes. You just take it and then press right here
and slide it away from the main board. Then you can take your new part and slide
it into place. Pretty simple. They are only about 5 or 6 bucks on Amazon. I’ll put that in the video description below
if you need one. Then there are the power buttons. If you have any questions be sure to leave

  1. I just wanted to point out one thing. The expansion port was originally designed to work with the CD Drive expansion back when Nintendo and Sony were working together on the system. The voting machine thing is news to me, but it's nice to see at least one other company was interested in making use of it.

  2. This console was obviously taken apart at one time. There's usually 6 to 7 screws holding the top RF shield on. 7 screws for older revisions and 6 for all the newer revisions starting with CPU 05 I believe. Then there's 6 screws holding the cartridge bay in place with two longer screws towards the edge connector that fits into the cartridge socket, the other four are the same size as those that hold the top RF shield and shell on.

  3. This video sounds as if Zack after 20 years doing JerryRigsEverything finally got tired of the whole shebang haha

  4. If you pause at 2:22 you'll see some Sony brand chips on the board. I had no idea Sony even made microchips back then. Also is that the Mitsubishi logo on the chips on the right side of the expansion connector?? I had no clue Mitsubishi made microchips, either! Fascinating stuff!! 😀

  5. You missed quite a few screws in your console. The top RF shield should have seven screws, not four. The loading tray has six screws, not two. The motherboard will have two additional screws, not one. Basically your console is missing eight screws.

  6. quick question, im trying to do the same thing replacing the 72 pin connector but even after that it still gives the red blinking screen. i mean i noticed on the new one the connectors the cartridge goes into are a bit slanted and tried moving them with no luck. is this just a gone console or any hope?

  7. Thank you for your vid, do you know a repair for these controllers that work erratically, other than cleaning?, mine when moving left or right do multiple moves with one press of button.

  8. Try re-soldering the connector before buying a new one, or the tiny thru-holes near it. Most likely worth the try. The connector is very durable and tolerates minor adjustments well. Good vid.
