I am hoping that there is someone out there who can help me out or steer me in the right direction.
About 3 months ago my Panny plasma (bought in 2009) developed a pixel width vertical line just off centre of the screen. The line stayed constantly on for about 3 days and then disappeared after turning on the tv on the 4th day. I knew that problems like this don't just correct themselves so I left it until now.
Since then, it has progressively been getting worst...
