I had that for a while, and the short term fix is to tilt the screen and it will disappear.....I do not know the cause or the technical solution (hopefully I am thinking of the same problem :) If it work's, your welcome,if it doesn't,I'm sorry :(
Sounds like you have a vertical output problem with the set, since the vertical driver has become defective.
A vertical line!
WHY THE LINE X=4 IS A VERTICAL LINE.
A horizontal line is perpendicular to a vertical line.
A vertical line has an undefined slope. For the line to be parallel to a vertical line, the slopes would have to be the same. Therefore, the line parallel to a vertical line also has an undefined slope.
A horizontal line is a line perpendicular to the vertical.
It is not repairable. You may replace yourself using some on-line guide. It is easy
all vertical lines are parallel to waht type of line?
its a line that is vertical and a symmetry
the slope of a vertical line is 0.
A vertical line has a slope of infinity.
A blinking vertical line is a cursor.
