Underball Posted June 9, 2010 Share Posted June 9, 2010 I've done the easier 7800 composite video mod, and really worked on getting it perfect, and it's just abotu there, except the overall tint is off/skews a bit green. Is there an easy way to add a simple tint circuit with a pot to adjust that I can place inside the 7800 shell, instead of having to manually adjust the TV back and forth depending upon which gaming system I use?

A.J. Franzman Posted June 10, 2010 Share Posted June 10, 2010 It already exists inside the console. R57 and R58, both 500k ohm pots, adjust the chroma phase in the 7800. R57 controls 7800 mode and R58 controls 2600 mode. Quote Link to comment Share on other sites More sharing options...
