Hi You have a ground loop problem. Rolling shaded bars are the classic sign of a ground loop. Your TV & AV gear are likely not on the same
ground level as the input cable line. The cable line is likely floating
to a different ground. But this is not hard to fix.

Vertical red lines no matter what input.


I'm assuming you're dealing with an LCD flat panel monitor.

If you've tried different input and from different computers and different cables, and you're still seeing vertical red lines, it's highly likely that the LCD is failing and there's not much that can be done easily to fix it. You will probably need to replace the LCD panel.

If the red lines are in different locations each time you power on, then it could be a controller board issue. But, if the lines are always in the same place, it's probably the LCD panel itself.

The text along the sides of the tv screen are not completely in view


you need to change the 'zoom' on the tv by the remote.
Normal mode frames the 4:3 video to the 16:9 picture area by displaying it in its original aspect ratio, with vertical gray or black bars on both sides of the screen. The disadvantage of this method is the fact that the image is small by virtue of not using the entire width of the screen. This is also known as the 4:3 mode.
Full mode Full mode horizontally stretches the 4:3 video evenly across the entire width of the screen. This is the proper mode to display anamorphic video. If used for standard aspect ratio video, everything on the screen will appear wider than normal. Contrast this with anamorphic video displayed without processing on a 4:3 display, in which people on the screen will appear taller than normal. This is also known as the 16:9 mode.
Zoom mode Zoom mode evenly stretches the picture both horizontally and vertically, until the picture fills the entire width of the screen. This crops out the top and bottom of the picture. This mode is used for letterboxed and open matte video.
14:9 mode Main article: 14:9
In 14:9 mode, the picture is magnified more than in Normal mode, but less than in Zoom mode, while retaining the original aspect ratio.
Wide Zoom mode Wide Zoom mode, also called Just mode, Horizon, or Smart Stretch, progressively stretches the picture horizontally, less in the middle and more on the edges. This allows normal aspect ratio video to be displayed across the entire width of the screen, with minimal cropping, and with much less of the unpleasing visual stretching effect of Full mode.

Red bar across top of screen??


I had the same horizontal, solid red bar along the top of the tv screen. I have an older analog Philips Magnavox TP2785C221. It just started all of a sudden. It was on every channel. However, the bar did not appear on the other input channels (e.g., AV1, AV2). So this meant that the red bar was only occurring on the antenna input. I unplugged my cable decoder box and restarted it. The red bar went away and that seemed to solve the problem for now.

Solid line completly across screen, monitor is brand new


Your comp's video card refresh rate (in Hertz, abbreviated Hz) may not be totally compatible with the monitor. Check the properties of your video card, and change the refresh rate (you may have to look around for it) to 60 Hz. This is a pretty standard refresh rate that works with just about every monitor. If it's already there, I'm afraid someone else will have to try and help!

Hope this helps, and please rate my answer, good OR bad.

Good luck!
