System only runs Mario/Duck Hunt. Out of ideas, need help!

Okay, so I'm kinda new to fixing NESs. So I've been following a lot of how-to's online and trying a lot of easy fixes, but so far nothing has worked. As of right now, I have boiled the 72 Pin Connector 3 times, I have cleaned it with alcohol twice, I have cleaned the contact points on the NES every time I have boiled the 72 Pin connector, and I have disabled the lock-out chip.

If the games work fine in your other NES, I would recommend replacing the 72 pin connector. It is an inexpensive part and will most likely fix your issue.

I would try using the "broken NES" with the 72 pin connector from the working NES, if it works, thats the issue. if it doesn't, then I would try replacing the mother board or try plugging in the cartridges in to it while disassembled to see if the cartridge loading mechanism doesn't make a good connection.

First, try blowing on the cartridges. It may sound crazy, but it sometimes works! If this does not work, then I would put in a new 72 pin connector. Try to make sure it is not a third party one. If possibl3, get the real deal.

Do you know it is the system not the cartridge
