I have a 40 in. Prizmo HD tv and a month or two ago most of my screen went dark (most dark on the left) and i wiggled my tv the smallest amount and it fixed it self. From then on it just kept getting worse and worse. I would have to tap the top of my tv to fix it but that method doesn't work anymore. If i pull the top of the tv towards me so that if i look at it from a side it looks like " \ ' the darkness would go away but these color lines would show up on the right side of my screen and now no matter what the lines wont go away and i have to really thick black ones. Is something loose? What's going on?
