I had a Sony early generation SXRD which I had ISF calibrated. Just upgraded to a a JVC 61 FN97 DILA. It's plugged into the same PS Audio AC premier regenerator as before. But now when I power off, the JVC loses its color, picture, etc settings. Didn't happen with the Sony. Is that just what JVC's do? Before I have ISF come out and calibrate the new display, I want to know if I need to have it constantly connected to power to avoid losing settings. Or is it a problem with my display?
