Like everyone says, if you don't have to push it down, you've got a refurb. I replaced pins in one of my NESes, and it won't work if I push the cart down. My two still-in-original-shape systems won't work unless I *do* push the cart down. Apparently, I need to inspect that one system that I replaced the pins on. What kind of wrong did I do there?
There is a little black plastic tab that needs to be slid under something - hard to describe without pictures.
There is a thread with pics where it was discussed before, but the setup of the new Forum Search has gotten me so frustrated that I now give up looking for it. Having to go into Advanced Search and specify that I want to search the body of a thread every time I hit search? Too much effort for this cowboy.
Edit: Looks like Dain changed the search back, nevermind, I will search for it.
Edit 2: Well, I can't find it. And, I don't feel like taking my NES apart to take pics. Rest assured that you are doing it wrong though.
