My 2 1/2 year old Samsung LCD has started to develop an issue with the screen after being turned on. The left hand side of the panel doesn't display a picture but instead shows vertical scrambled lines.
After a short time the image sometimes comes on but is usually washed out or white.
I have found that if I tap the back of the TV gently the screen normally comes right. I am wondering if there is maybe a loose connection in the back somewhere - It does the same thing no matter what input etc it is getting feed (Sky, PC or XBox)
