i have this model for 5 weeks and i am very pleased but i am finding that in the viewing mode (cinema)settings contrast, brightness,ect that the settings are not being saved automatically in the different input modes. if i alter say contrast in av1 mode it alters in all the input modes in (cinema). also in the power on preference i have set to av1 in all inputs modes but tv tuner mode powers up. are these faults or is it me.
