Hey everyone. I just bought a TH-42PZ80U about a week ago after hearing many good things about this TV. It's my first HDTV, so please be patient with me. I have tried a lot of different settings on these forums, but no matter what the picture is still pretty grainy. I don't know if it's the TV or what. My dad let me try out some nice HDMI cables so I don't think it is that. I play the movies through PS3. So far I have tried the Spider-Man trilogy on Blu-Ray and Planet Earth on HD-DVD, both being somewhat grainy. I have tried cinema mode and various settings. I am looking at the LN40A550 now. Is my TV messed up? I don't know if I should keep this or get an LCD. Please help, its appreciated!
