Hello my tv had got white vertical lines for last 1 month. Initially they disappeared after 5 minites or 10 minutes but later they didn't. I called michanic and he said there is moist in screen and it will have to be changed. It will cost almost equal to a new TV. I searched on net. And thanks to all people who share tips on net. I also used my mind and dried the scree and back part with a hair drier without opening it. And to my great surprise lines completely disappeared. I saved my 40000 rs. I am so so happy. I want to save others too that's why I m sharing it.
