72 Pin Connector Instruction

I take no responsibility for these directions, a previous buyer sent them to me, and I have posted them for reference.

If this is your material, E-mail me.

Here are some quick instructions that I have found on the internet. Please read them carefully. There are a few things you need to be made aware of and the first one is that this is not a 100% guaranteed fix for your NES. You may have damaged something else during use a while back. The second thing is that you are trying this on your own and I, in no way, shape, or form, am liable if you bunk up your NES even more than it was before. My NES currently works great but on occasion it has a tad bit of trouble reading games if they are dirty. We recommended that you clean each of the games prior to playing them in the "new" system. You can use a Q-tip dipped into rubbing alcohol and just wipe along the teeth of the cartridge. Make sure you don't get any alcohol inside the cartridge and always dry off the cartridge's teeth with a dry Q-tip before testing the game.

The only tool you should need for installation is a Philips screwdriver and a clean place to work.

Your first step is going to be to flip the NES upside down and remove the 6 philips screws. I have taken the liberty of circling the screws in the following picture. After you remove the screws you will want to flip the NES back over and remove the top cover.

Remove 6 screws from bottom
Your will next want to remove the large silver cover by removing the 7 screws holding it in place. Again the screws are located in the red circles.

Remove silver cover
After having removed the silver cover, you are going to need to remove the cartridge slot. In order to do this you will need to raise the motherboard out of the deck casing a bit. To do this, I removed all 6 screws holding the cartridge slot as well as the 2 screws holding the RF module down. All screws are circled again. Once you remove all the screws then lift the motherboard out of the casing and slide the cartridge slot out towards the front of the console. Make sure you pay attention to how it goes on as you will be putting it back on during reassembly.

Remove cartridge slot
Next, simply pull the 72 pin connector off the motherboard. It can be snug and so you might have to tug a little to get it off. Obviously it slides off towards the back of the motherboard. Now connect the new connector to the motherboard. Make sure you pay attention to how the connector goes on (the side with the two rows of matching silver connectors are what slide onto the motherboard). You also want to align the screw holes when you push the new 72 pin connector on the motherboard.

Replace connector

Before reassembling the NES, make sure the cartridge slot will click down into place when putting a game in. If it doesn’t, loosen the screws and then pull the cartridge slot forward just a little. The front edge of the slot needs to hook under the motherboard in order to fit properly.

Reassembly

Slide the cartridge slot back onto the 72 pin connector.
Ease the motherboard back down into its original position and screw the cartridge slot and RF module back down (8 screws)
Attach the silver cover (7 screws)
Attach the top half of the NES deck casing and turn the NES onto its top and screw it together (6 screws)

Remember, your system will only play clean games. If you try and put a dirty cartridge in your newly refurbished system, it probably will not work. You took the time to repair the system, now take the time to clean each and every game you have so you do not dirty up the new 72 pin connector you just installed. Make sense?
