Question about Nintendo NES Console

Games won't connect

My Nintendo NES was working fine until I tried to put a game in and it will not connect and play. The screen blinks grey and black. But if I push down on the game in the console it will connect and play, but once I release the pressure on the game it disconnects. Any suggestions?

This is an issue with the 72 pin connector in the system. The contacts inside the system start wearing out or corroding and don't make as good of a connection as they used to. There are multiple places online, such as ebay, where you can buy replacement connectors for the system. The actual repair itself is quite simple. There are many places online that tell you how to do the repair and many places that sell the connector usually include some instructions.

The red light flashes on my NES and on the TV screen, it keeps on changing colors. Do you know whats wrong?

The NES is touchy like that, sadly-- your problem isn't uncommon. My NES, and the NES of nearly every friend I have who still owns one, plays this little trick on them from time to time. Here's what we do:

1. Turn off the NES console.
2. Blow into bottom of the game, near the chip that connects to the NES.
3. Wipe away any excess dust from the game itself.
4. Blow into the console of the NES.
5. Wipe away any excess dust.
6. Re-insert the game and try again.

If this doesn't work, try placing the game in more delicately, or with more force. It's just a matter of trial and error, and sometimes it will work faster than others. Hope this helped!

My nes blinks on and off

This can be caused by several things. The games may need cleaning, the system may need cleaning or the games may not be connecting properly.

Games can be cleaned with a q-tip (that's what I use). I don't know what you'd use to clean the system if you don't have the cleaner cartridge. (The fix link below talks about opening it up to clean it before it gets to repairing the connector.)

Try holding the games down while they are in the system, if they work now it's probably the connector. If it's the connector you can either replace it, try to fix it yourself (don't try this if you aren't good with a screwdriver/tools) or use something to hold the games down. (I jam a Lego block in mine. 1 long block with a thin block on it.)

If the games you are trying aren't Nintendo licensed, they may be failing the lockout chip test. (They should have a Nintendo seal on the label)

Good luck.

Nes light keep's blinking

well, heres what you do.. turn it off, and eject the cartridge.. blow in the bottom where the chip is to get rid of any dust, and put it back in.. turn it on.. if it still blinks, turn it off, and eject the game again.. this time blow into the nes itself.. put the game back in, and turn it on.. if its STILL blinking, grab another cartridge, and TURN OFF THE NES its very important. press down on the game you want to play, like your going to eject it, but instead of letting it up, slide that second cartridge you grabbed in on top of the first one.. turn the nes on, and enjoy...

it SHOULD work... if not, try taking a q-tip and dipping it in hydrogen peroxide, and cleaning the nes and game.
