i've had my panny 37pv500 less than a week now. i've got it running in normal mode and reduced the contrast as everyone suggests. the problem i am experiencing is a faint yellow rectangle appears every now and then towards the top left hand side of the screen. have i done something wrong with the settings, is there something wrong with my screen or is anyone else experiencing it aswell. other than this i am well pleased with my purchase. i get the buzzing from the rear that a lot of people have mentioned but only seems to last a few minutes then goes once the set has warmed up. please help!
