I have a Beovision 7 Purchased in 2009. The image has recently been displaying a vertical discoloration of the extreme left of the screen approximately 3 pixels wide, at the same time, the vertical alignment of the image seems to be affected. This is not always happening, but tends to happen during each use. Any suggestions of how the problem can be fixed, or anyone with similar experiences? The unit was purchased in Washington DC, but I do not have a local service/dealer in Ann Arbor. Any advise would be welcome.
