HI, I JUST BOUGHT A PANASONIC V10 PLASMA AND ONLY WATCHED FOR ABOUT 5-6 HOURS. IVE BEEN WATCHING IT ON THX MODE WHICH DOESNT LET YOU ADJUST CONTRAST OR BRIGHTNESS, IS THIS OK FOR THE BREAKING IN PERIOD (AND BEYOND), OR SHOULD I PUT IT ON SOME OTHER SETTING AND TURN DOWN BOTH THESE, AND IF SO TO WHAT LEVEL? ANY ADVICE IS MUCH APPRECIATED, THANKS!
