    • Remove the six 13.25mm Phillips screws on the bottom of the game console with a #2.5 flathead screwdriver.

    • The screws are recessed about 40 mm.

    • Flip the game console right side up and take off the top by pulling it up and away from the rest of the device with your hands.

    the outside screws are a little deep, plan ahead :)

    Why use a slotted driver? The screws are phillips. Both #1 and #2 work for me.

    • Remove the two silver 17.45mm Phillips screws from the cartridge tray using a Phillips head #2 screwdriver.

    • Remove the two bronze 13.25mm Phillips screws from the cartridge tray using a Phillips head #2 screwdriver.

    • Slide the cartridge tray toward you, away from the 72-PIN connector, and off the motherboard assembly.

    There may also be two short/yellow screws at the upper (back) right and left of the cartridge tray.

    • Note: Underneath the cartridge tray is a black trapezoid-shaped tab/lip (see marker). When properly assembled this tab/lip goes below the motherboard and shielding as seen here.

    • During reassembly, make sure you orient this tab underneath the motherboard in addition to orienting the tray on top. Failure to do so will bow the cartridge tray and place stress on the component, causing the cartridge spring mechanism to bind.

    This is so unclear! I have no idea what tab this step is referring to.

    So, it’s a year later, and I have a lot more experience with this system now. The front of the cartridge tray needs to hook under the edge of the board.

    It’s much easier to get the tray on and off if you just make sure the board is unscrewed from the case. Then pick the board up a little and the tray should be much easier to slide on and off.

    Me too... No idea whatsoever

    its when your replacing the cartridge tray, if u do it wrong the tray will feel like it's bowing up in the middle, like when u put in the screws u have to press the tray down to get the screw holes to line up / be flush, if u get the lip underneath to catch correctly there will be no issue/bow u wan't have to press down on it, or make the screws pull the tray to the motherboard, instead the tray will be flush with no pressure applied, i had no idea what he meant either until i was reversing the steps.

    also not all NES are the same underneath, my tab was much less noticeable and i had one less screw to get the shield off then he showed. and 2 less screws to remove the cartridge tray.

    This seemed very unclear to me at first, until I tried to replace the cart tray. I apparently didn’t get the little lip under the mobo on my first attempt, and I noticed there was a pretty decent chunk of space between the front brass screw holes and their corresponding holes on the mobo. I reseated it, and the second time I heard a little click (apparently the lip going under the mobo). This time the bottom/brass screw holes were virtually FLUSH with the mobo holes. If you see a chunk of space between the cart tray and the mobo near the brass screw holes you didn’t get the lip under the mobo.

    I’ve added a new, better picture with additional clarification. Hope this helps.

    • Remove the three 13.25mm Phillips screws that secure the motherboard to the lower case with a Phillips head #2 screwdriver.

    • Pull the motherboard assembly straight up and out of the plastic case with your hands.

    • Turn the motherboard assembly over so the metal cover is facing you.

    I did not have the bottom right screw on my NES

    if you look at step 2, that shield overlaps the place where the bottom right screw would be, so there's a big gap if you put one there!

    • Disconnect the wire harnesses from the motherboard assembly:

    • Player 1

    • Player 2

    • Power

    • Make sure you remember where player 1 and player 2 cables are plugged in; do not mix them up. A good technique would be to write each title on a piece of tape and wrap them around the appropriate wire.

    • Lift off the EMI shield (metal cover) from the motherboard assembly.

    • Turn over the motherboard assembly so the 72-PIN connector is on the top of the motherboard assembly.

    would have been really nice to show a Step 8 in pulling off the 72-PIN connector has i had to just guess that it would just pull off. it took a little force and at first i thought it was attached via something i was missing, Also anyone who wants to know when removing player 1/2 and the power and reset "big blue tab" don't pull on the wires but try and get your fingernail/jimmy on either side and nudge it going back and forth until you get some release a little, then go to other side and so same until you can get a better grip and just pull it out

Because it wasn't terribly clear, the pin connector pulls off from the motherboard. Just pull straight away from the board to clear the connector. It takes some force to get it off.

Dylan Peterson - Contestar

And, no wires need to be disconnected either.

Very easy repair.

"How to replace your 72 pin connector"

Leaves out the steps that show how to remove the 72 pin connector.

Connor Gray - Contestar

I replaced mine, and I'm still getting a solid white screen. Any ideas what else it might be?

I replaced my 72 pin connector and now it seems the games wont eject all the way up, it stops at like a midway point. And taking the cartridge in and out is super tough! Any ideas guys?

Matt Smith - Contestar

To remove the 72 pin connector once unscrewed just wiggle it out. Replacement connectors are very tight to insert and pull out games (this is normal).

Taylor hoskins - Contestar

Don’t waste your money replacing the 72 pin connector. Refurbish it without removing it from the mother board. Stop after step 2. Use a dental pic to bend the top 36 pins. It’s tedious……but free. Be careful not to over-bend them, you can fix it but it’s a pain. Take some fine grain sandpaper and fold a piece over the blade of a putty knife and duct tape it on. Insert the sandpaper clad putty knife into the 72 pin connector (straight in, straight out, don’t slide left and right while it’s in there) Move one putty knife blade width left or right and repeat until you have cleaned all the pins. Use a game that has already had it’s connectors cleaned to test the machine before you put the rf shield and the cover back on. If you can’t get the game to play re-examine the straightness of the pins you bent and run the sandpaper putty knife through there again. After you get it to work, then put the rf shield and cover back on.

I would very strongly advise against using sandpaper inside any cartridge-based system as it can leave some sand residue in the connections, which would in term wear out the contacts on the games faster.
