Over the past year I have repaired probably 25 blinking nes toaster variety consoles by replacing the 72 pin connector. For the most part these repairs are simple. However, I have several units that still do not work despite replacing the pin. I know the pin works because I later use the connector on a different console and it works fine. The units that don't work with the new pin either have a white screen or a green sreen when they are turned on with a game connected. Do any members of the restoration society have any tips on what could be the problem and how it can be easily fixed (if at all). Thanks for your help in advance. :/
