LCD Display problems.
Many of the new LCD TVs are seeing their screens fail after very little use due to bad/open connections between the the LCD panel and the micro connections on the edge of the screen. This can produce a variety of symptoms which include vertical lines through the picture, double images, a dark picture, no picture, negative images, and smearing. While I’m sure it can cause other symptoms I have not mentioned. I discovered that spraying the edges of the display with freeze spray can be a quick way to determine if the LCD display is at fault.
