Possible to fix mechanism in NES cartridge slot?

[GorillaSpawn]

I got an ok deal on a toaster nes from ebay. Cleaned it up, bent the pins up on the old pin connector, and clipped the lockout chip (thanks for all the guides!).

 

However, the mechanism for keeping the cartridge down is really tough to get to click into place. Any way to fix this? Now that I've adjusted the pins, I think I can get most games to work without having to even do this, but I was curious if anyone has any ideas other than taking parts from another NES?

First of all, make sure you reassembled the thing properly. The black plastic cartridge tray has a tab which slides underneath the PCB. It's really hard to see and takes some work to make it fit properly. I had to disassemble four of my "fixed" NESes when I finally figured out why the trays weren't sitting properly upon reassembly. Screwing the tray together/down tightly with the tab on on top of the PCB can deform the plastic and cause the latch to stop latching.

 

Most of the time, putting the tray back in properly will fix this problem. If not, take the tray back off and look at the front latch mechanism. You'll see a cheap wire spring/clip thingie. Make sure it hasn't fallen out of place and is clicking in and out of its slot properly when the whole thing is disassembled. On one of mine the clip had fallen out of place; I pushed it back in (just pushed it with a screwdriver, no bending or anything) and it worked again.

Loosen the screws on the track a little bit. If you screw them down tight it will not latch. Just loosen them up alittle and push down to see if it latches.

I actually just made a post about this.

 

Yeah, there is a little catch on the bottom of the spring cart guide. Make sure that it is slid underneath the motherboard for optimum clickage.

It was doing this before I took it apart, but I think the problem is that the actual catch itself (looks like a pin in white plastic?). I looks sort of warn out and doesn't want to click into place. I'll fiddle with it and see if I can adjust it somehow, the bay too.
