Yea the on screen menu text, I've tried multiple sources(personally modded genesis, SNES, PS2 all using Y/C). So, I messed with the gain and bias for all colors, it does't go black but it does fade the color and darken the screen. Green does nothing, red simply dims and blue seems off. If I hit the blue only button, it seems to turn everything purple and not blue. Changing the color temp to 93 makes it all look purple as well. It's as if red is a constant part of the overall image. I spoke with the seller and he's willing to take it back or offer discount. At this point it's probably going back.
