Hey, Sorry it took me so long to reply. Ok, so I should direct everyone to a nes repair guide on our site that is really much more complete than what we can fit into a short video. The key here is that there are two things you need to do to ensure (i.e., have a 95% chance) of fixing your NES system.

1) Replace the 72 Pin Connector
2) Clean your games

The repair guide I linked to above shows you how to do both of these things in full detail. It also provides links to several products we have designed, developed and put together that offer all the parts you will need at a very low cost. We also work with our customers to resolve any issues they have with their repair, so even if you can't get it working (5%) we will help you get a replacement system at a reduced cost. I hope this helps, and thanks for posting!

Nate, I know info on the lockout chip is floating around the internet as if that is a solution. I want everyone who is reading this page to know that disabling the lockout chip IS NOT a solution to getting your NES games to work.

Here is what is really going on. Your NES 72 Pin connector's pins are formed to press against the metal contacts on your NES games. Over time, pressing games into and removing them from this connector cause those metal pins to bend away and reduces the effectiveness of the connection with the games. You need to replace the 72 Pin Connector to make that connection tight again.

Also, over time your games build up dirt and grime from finger oil, moisture from breath (when you blow on them to get them to work), from dust building up on the natural oil residue from the manufacturing process, and from your basic rust/oxidation. You need a professional cleaning product to get these games open and clean again, and we have exactly what you need in our NES Game Cleaning Kit.

PS - the only good disabling the lockout chip will do you is allow you to play games made for another area of the world (Japan), IF you do it correctly. We have actually experimented with this, and have found that the myth of disabling the lockout chip will allow you to play games again is a COMPLETE HOAX. You simply need to fix the actual problem as described above.

Hopefully this helps. Thanks for watching and posting!
