Question about Sony KP-57WS500 57" Rear Projection Television
I have horizontal green lines across screen approx 8 to 10 inches apart-seems to come and go depending on what colors or background color are showing- not sure what model it is- I bought it 2002
Those are called retrace lines and they are the result of the blanking pulse not having the desired effect. This could denote a problem in the Horizontal section of the TV. In this case the green gun is not being turned off as it goes back to the left side of the screen.
