Hey guys, so I did the video mod on my 7800 a couple weeks ago, the 7800 games work great and the 2600 games worked fine before but a little interference. All of a sudden this morning, the 2600 game's colors became inversed, for example the green is blue. How can I fix this? I checked the solder joints but they seem okay, is there something I can check to fix this. Pictures would be great!
Thanks a lot and have a great night.
