I just got a new ST50 and there are two things going on that I'm not in love with. Thing is, this is my first plasma so I have no idea if this is to be expected or not.
To make things even more difficult, I don't know how to explain what is going on - I guess I don't know the tech terms - so I created two Photoshop comps to illustrate the problem. Here we go.
1. When I'm close to the TV, let's say 3 feet, I see some weird granulation on the screen. It's like a 64 or 32 colors .GIF image, the transition between colors is not smooth. See the picture attached, where I split the "screen" in two. On the left is what I would normally expect. On the right is what I get from my brand new plasma.
Immediately after I saw this problem, I drove to a nearby Frys and I looked at other TVs. No LED or LCD exhibited the same thing. Unfortunately they had only a couples of plasmas and they all had the same problem - granted, not as much as my Panny.
I saw an LG right next to a ST50 and while both had the granulation thing, clearly the ST50 was worse.
This got me thinking this might be a plasma thing, but here I am, hoping for an answer from people smarter and more experienced than me.
2. When I have a colored background and some white shape over it, some strange horizontal bands appear, spanning the whole width of the screen. They are very dim, but I have very good vision. See the second pictured attached, with the green background.
I saw this when before a trailer you get the rating screen, with dark green background and white letters. I see fade, white stripes running the width of the screen, one at the bottom of the letters and one at the top.
I'm pretty bummed. I bought this TV because the consistent great reviews. I hope this unit is bad and the two "traits" I just described are not a plasma characteristic.
Please chip in, and thanks in advance.
