Hi there. A while back I bought a NES console from a fella close by. Works great. He also gave me another system for free as the outside case is a bit grotty and he didnt think he could sell it, but it needed a new 72 pin connector in it which I bought and was installed in Feb 2008. He also disabled the Region lock for me so I could play games from the US, so I tend to use this one to play all the games from the US and AUS so I am not changing consoles. Now when my son puts a game in, the tv screen is grey or green and the game is not playing. I inserted the game in the original NES console that I bought from him and it plays fine (other than the fact that the region lock isnt disabled in that one and it blinks....yes I need to get it disabled in that one too LOL)....so I know its not the games. Where do I start??? Thanks in advance for your help :))))
