There are two things you will need to do to be sure to fix your NES system so games are working first time, every time:

1. Replace the 72 Pin NES Connector, and
2. Clean your NES Games

Tools you will need

• New NES 72 Pin Connector
• Phillips Head Screwdriver

Replacing the 72 Pin Connector in your Nintendo NES system is quick and painless. The first step is to open the NES system case. To do this, flip over the NES system, locate the 6 screw holes, and remove the screws with your phillips head screwdriver (see image to the right). Once the screws are removed, you can simply lift the bottom of the case away and flip it over to reveal the "business end" of the system.

With the NES system rf shield (shiny metal thing) exposed, locate and remove the 7 screws (see image to the left). With these screws removed, you will be able to lift up and remove the NES system RF shield.

With the NES system game tray exposed, locate the 8 screws on the NES system game tray and motherboard (see image to the right). With these screws removed, you should be able to lift the NES motherboard and game tray away from the bottom of the NES system case.

With the NES motherboard removed from the case, you should be able to simply slide the NES game tray away from the 72 pin connector to remove it from the motherboard. This will expose the NES 72 Pin Connector.

To replace the NES 72 pin connector, simply slide the old 72 pin connector away from the NES motherboard. Once removed, we highly recommend you clean the metal contacts on the NES motherboard itself before replacing the 72 pin connector, as sometimes not doing so will actually prevent the new 72 Pin connector from making proper contact. Our NES Total Repair Kit contains all the supplies you need to replace the 72 pin connector and clean your games. The game cleaning supplies provided in this kit can also be used to clean your NES motherboard contacts.

Once you have cleaned your NES motherboard contacts, simply take the new 72 pin connector and slide it onto the NES motherboard contacts in the same way as the old connector. To reassemble the system, follow the same procedures in reverse. One tip to avoid issues, when you slide the NES game tray back onto the motherboard, make sure the small plastic tab at the front-bottom of the game tray slides underneath the motherboard. Sometimes this tab gets caught on top of the motherboard. If so, you will notice that the game tray will not lock down properly. If this occurs, simply fall back to that step, correct and reassemble.

Tools you will need

• Nintendo 3.8mm Gamebit Game Opening Tool
• Nintendo Game Cleaning Paste
• Nintendo Game Cleaning Rinse
• Non-Static Game Cleaning Pads

Using the 3.8mm Security Bit, unscrew the 3 screws from the back of the cartridge. Our 3.8mm bit is designed to fit in screw holes easily, but this still may require some pressure. To open the cartridge lift up on the back side and pull towards you. Be careful not to lose the screws!

With the back of the NES game cartridge removed, you should see the NES game motherboard exposed (see image to the right). The business end of the NES game motherboard is the side with the shiny metal contacts. If you inspect these carefully, you may notice dull, gray or brown smudges. This is built up dirt and grime from oil on hands, and the oil from the factory combined with dirt and dust. This actually disrupts the electrical connection if bad enough, which is one of the major contributors to NES games not playing properly.

Using the supplies in our NES Game Cleaning Kit, you can clean these metal game contacts till they shine, and work to play your NES games properly. First, remove the NES game motherboard from the case. Next apply a small amount of NES game cleaning paste to one of the non-static game cleaning pads. Then, rub both sides of the metal contacts with the game cleaning paste (now applied to your non-static cleaning pad). You should see dark brown and black build up being removed. This is normal. Continue to rub away dirt and grime until the metal contacts appear clear of any build up. Finally, apply a small amount of game cleaning rinse to your non-static game cleaning pad and rub down the metal contacts once more to remove any left over game cleaning paste residue (this prevents dirt and grime from building up again as quickly). Let dry, and follow the procedures above in reverse to put the game cartridge back together again. You now should have games and an NES system that work first time every time, congratulations!
