So I opened it back up, removed the shield and the cart tray and moved the 72 pin connector around. left, right, back, forward a few times, then put a game in and kept moving the connector and testing it, eventually it recognized there was a game! Kept trying more games, all working. So I just put the pieces back 1 by 1 testing after each piece with success!

I dont know exactly what fixed it, maybe the 72 pin connector was not aligned right or maybe the moving it around scraped more dirt off, but it works

Thanks for all the help and suggestions. Im so happy to get this working again, its my original one from when I was a kid so has a bit of sentimental value to me! Its now back as my main console.

I have one NES console that the 72 pin connector is slightly to the side in the cart slot. Whenever I insert game carts, I always have to make certain they are pushed all the way to the left side of the cartridge tray or else the pins don't line up correctly and I get the gray screen. You might try pushing your games to either the left or right side in that console and it just might solve the problem, or else take it back apart and try to nudge the 72 pin connector left or right where it plugs to the main board to fix the issue completely.
There is some adjustment you can do with the cartridge carrier, and as mentioned above it is possible to have it aligned poorly. To rule this out you can always try to get the cart working without the carrier installed.

Check for bad solder points, it's not common but can happen. You might be able to see fractures in the board if you look hard enough but it's not always that easy. If you're ok with soldering you could probably remake a connection by scraping some of the green laminate off of the board and soldering a bridge wire. At your own risk.

I have to be the idiot to ask but you are cleaning the games prior to testing too right?

Holy-SNES, good idea switching the working connector, I will gave that a try and keep my fingers crossed!

I have a horrible feeling it will turn out to be the board only because I seem to get the same result from the original connector and the new connector.

If it doesn't, you know the problem lies with the board.
This is what I would do.
If it didn't work at all I would lean towards something else being fried,
but because you say it works 1% of the time, you need to troubleshoot it with other working components.
The working pin connector would be the first thing I'd try.
Keep us posted with the results ]]> http://nintendoage.com/forum/messageview.cfm?catid=8&threadid=70185 2012-05-10T06:17:01 -05.00 ultimatetj 11
