Hi there, first time poster, so apologies if Im in the wrong place for posting this.... I tried to set up my wife's SNES before Christmas to play some games with her, but I had this graphical issue: http://imgur.com/jio6NoN This happens with all of our games, and doesnt change based on using the RF connector or the A/V one either. Ive also tried rubbing the contacts on the console with a piece of cardboard (its what I had to hand) and rubbing the contacts on the carts too. Im just wondering what my next step would be, my wife loves her SNES, she has had a long time, and we dont want to have to throw it away. Any help would be very much appreciated. Thanks
