Vizio model L30WGU made in 2005 .
It works just fine accept 20 or so very fine , as thin as a pencil line .red lines going up & down the entire screen evenly spaced . If i choose normal picture mode with black bars on both sides the lines do not show in the black side bars . Also the red lines do not show on top of any on screen menues . When the set is on with no signal those lines are there , when i plug a video input ito the video jack the lines go away for a half second .
Any ideas ?
