I have a 3 year old Panny 34 wx50 hdtv and ive noticed that the pq is not the same as when i bought it. I remeber the hd picture on this tv used to be crisp and real clear. Now I notice that the picture seems a bit more grainy and the picture lacks some depth from how it used to be. I can see more imperfections in the pictures than i used to. Before it used to be more crisper and cleared. I used to get the feeling at times I was looking through a window now i dont. Is it normal for a tube tv to lose some clarity in 3 years. Now if i stand back at about 13-14 feet the picture looks amazingly clear and has depth from the typical viewing distance of about 8-10 feet it lacks the wow factor. How can i get my tv to look like it did when i bought it. I have calibrated the tv via avia and i have it set perfectly but still no luck.. What do i do. If I call a tech can he fix this. Can it be that the lenses lose focus over time. Can a tech perhaps clean the tv inside or perhaps re focus the tv.. What can I do.... My tv model number is Panny ct34wx50 hdtv..
