Hi. I have to ask this, as I'm trying to revive my LC 575. I know that you can use the logicboard of an LC 575 to a CC to form the Color Classic Mystic but is the CC's board compatible with a LC 575? I have to test if the 575's analog board or if its the logicboard which has the problem because with this 575, everything works (chime, HD loads, boots) except that it does not have video and I've tried raising up the screen control on its bezel.
