I'm having a little trouble with my F18A modded ColecoVision. The white color is more bluish and the colors are a little muted. After playing for a bit they sometimes will correct itself, and possibly go back to the bluish hue. I'm thinking that it's a solder issue to the vga connector. Does anyone have any information as to what exactly is happening and how to fix? I will open it up later today after I get done with work and see what's happening in the inside.
