Hi,
I just purchased a Panasonic 42" HDTV Plasma. Thrilled. I am extremely picky with PQ, almost to paranoia levels. A couple of things, first, I noticed a small level of video noise speckle on the black areas (like in the black bars or dark shadows, more like dancing speckling pixels, very faint) using a DVD player with S-Video interface (looking for an HDMI capable replacement for the holidays though). This so called "faint grainy noise" is like a motion of grainy dark colors only in the black areas (and visible while looking at the screen a very close distance, inches to be precise). Why is this? Normal with Plasma sets? inherent with the signal? Will it go away with progressive component and HDMI? All I have attached right now is an old DVD player and a DTV box using composite. I barely calibrated the set using commercial DVDs with the simple and plain THX setup menu (don't own Avia nor DVE). And I'm using the same old Pioneer Elite DVD Player that I used with my 10 year old CRT set (and same quality cables) and it never showed anything similar. Although this 'noise' is subtle, I'm worried this might be a defect. Please help me sort this out so I can be sure if this is a defect or if it is normal.
Second, there is in fact a greenish bias that cannot be corrected with ease using the basic user's menu settings. Without the proper training and living in South America (Venezuela), how can I resolve this? where can I contact or have an equivalent service like the Imaging Science Foundation nearby? Is there a possibility that I might perform this calibration myself and how? I heard that more damage can be done if you poke around the service menu without the proper knowledge. Help!
Thank You
