I've just bought a Philips 42PF9966. The picture is brilliant apart from one thing - the black level which is a darkish grey (looks like its somewhere between rgb(64,64,64) and rgb(80,80,80)) but significantly brighter than the colour of the screen when it's turned off (dark grey). I know plasma's don't have the same deep black levels of CRTs but my PF9966's seems too bright (even for plasma). I've played around with the brightness control (has no effect on black level below about 45 although does seem to darken images). I've calibrated the screen with Video Essentials but black just ain't black enough (it's annoying me). So, will the black level get better after the 100-200 hour plasma run-in time; is it something your eye just gets used to; or does my screen need some pro tweaking to improve the black level? Thanks for any info. P.S. Anyone any idea how to call up the PF9966 service menu?
