How to Repair and Refurbish Your NES Console
The Problem: Blink of Death
Many NES consoles have what I refer to as the blink of death, meaning when you insert a game cartridge, the game doesn't start, and the system blinks a blank screen. This is caused by a poorly designed 72-pin connector on the original NES console. The connector that accepts the game cartridges is prone to getting dirty and getting "loose" very easily. For the NES to be able to start games successfully, the connector needs to be cleaned and adjusted so that the pins make firm connections to the pins on the cartridge.
The Wrong Solution: Blowing into Cartridges
Many people have found that if you blew into the game cartridge, it would sometimes start correctly. Some think that it wasn't the blowing that helped, but rather the multiple repeated attempts that finally got the system to read the game. Also, saliva has a bit of salt and electrolytes, so it's possible that it helped bridge connections between the game and the console. The reality is that this is a very bad idea, continuous blowing will result in the contacts getting dirty with spit and will corrode the contacts over time. So don't blow on your games, but rather do the proper cleaning described below.
Note: This article has the brief condensed instructions, for more detailed instructions with pictures check out How to Repair Your NES.
The Correct Solution: Clean & Adjust the 72-Pin Connector
- Turn your console upside down, and remove the 6 screws. Use a small phillips-head screwdriver, and be careful not to strip the screw heads.
- Flip the console over and remove the top half, and set it aside.
- Remove the aluminum shield by removing the screws that hold it down.
- You'll need to remove more screws, this time the ones holding the black cartridge holder. After you remove the screws, it will slide forward and out.
- Now you should be able to see the 72-pin connector. You need to remove it by gently sliding it towards the back of the system. It helps to do one side at a time, in a shimmy-ing motion. Take care not to bend the circuit board too much. Take your time.
- After you have removed the 72-pin connector, clean all of the metal parts of the connector with rubbing alcohol and Q-tips. Also clean the silver-colored contacts that the connector was touching on the circuit board before you removed it.
- Now we will adjust the pins on the connector to more firmly grasp games. What you need to do is take a eyeglass repair screwdriver or any tiny flathead screwdriver and bend the pins back up from their sunken position. This is a bit difficult to explain in words, so check out the pictures of this in action in the detailed NES repair instructions.
- After you cleaned everything, allow it to dry thoroughly. Then start to re-assemble the system by working backwards.
- Before attempting to start a game, ensure that the game's contacts have been cleaned with alcohol and q-tips. Let the games dry. Then the game should start with no problems.
- If the game does not start, your 72-pin connector is probably too degraded to fix. You can easily buy a replacement connector for less than $10. Check out the bottom of the detailed NES cleaning instructions for buying options.
- Enjoy your classic games, might I suggest some Tecmo Super Bowl or Battletoads?
