If you've ever owned or played a NES System, you may have experienced a blinking screen or trouble playing your games.The cause of all these problems is the bad electrical connections between the game and the console.You can repair your games and system with a little patience.This guide will show you the areas you need to focus on when cleaning and repairing your console.
Step 1: If you have a NES, turn it upside down.
The red arrows show the 6 screws that need to be removed.The top half of the case should be able to be pulled up once the screws are loose.Don't loose any screws!
Step 2: The RF shield needs to be removed from the top half of the case.
Most of the NES internals are covered by this metal thing.You will be able to pull it up if you remove the 7 screws.
Step 3: Pull the mainboard out of the case by removing the 8 screws holding it down.
Don't pull it too far because there are still wires attached to the mainboard.
Step 4: The controllers and switch assembly need to be removed.
The mainboard will be removed completely from the case.The lower RF shield can be removed with the mainboard out.
Step 5: There is a worn out 72 Pin connector on the mainboard.
It could take a little force to get it out.The old 72 Pin NES Connector is likely worn out and can be thrown away.
Step 6: It's not possible to make good electrical connection to the mainboard with the dirty contacts on the 72 pin connector.
Our Non-Static Cleaning Pads can be used to clean the contacts of the new Nintendo repair part.I highly recommend using our cleaning paste to clean the contacts, it will get rid of all the dirt and bring the contact back to a smooth shiny surface.Using the paste, apply a small amount on a Non-Static Cleaning Pad and scrub both the top and bottom side of the board.You should see a lot of black dirt coming up from the connector, however in our experience you only need to keep cleaning until both sides are clear of dirt.After the Nintendo NES Repair Cleaning Paste has been applied, be sure to wipe the PCB completely clean with a Non-Static Cleaning Pad and some cleaning rinse.If you haven't already, make sure to clean and rinse both sides of the contacts by flipping the mainboard over and repeating the process.Dry both sides with an unused cleaning cloth.
Step 7: The new Nintendo repair part can be slid onto the clean and dry Nintendo contacts.
It will be a tight fit, so make sure to push it on all the way or it won't make contact.Put it all back together after reverse order.It's important that the plastic tab at the front of the spring loader snaps in place.If not, the spring loader will either get stuck in the locked down position or not lock down at all.I recommend testing the unit out with a game to make sure everything works.
