The 72-PIN connector is a piece of hardware inside of the game console. It has 72 metal pins, which come into contact with the metal spokes inside of the game cartridge to register the game. The pins on the connector bend out of place over time, and the game console can no longer register your games. This guide will show you how to locate and remove your worn out 72-PIN connector.

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.
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.
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.

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.
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!

Lift off the EMI shield (metal cover) from 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.
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.
Priceless
Um are we missing the last steps on how to actually remove the 72pin connector???
I replaced mine, and I'm still getting a solid white screen. Any ideas what else it might be?
The 10NES Chip. Mr. Glitch's Retro Reviews: HOWTO: Fix the NES Red Light Of Death (mrglitchsreviews.blogspot.com) See this guide to learn how to disable it.
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?
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).
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.

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