There is a tiny spec on the scanner glass. Cleaning it will make the line go away.

Depending on the age of the monitor, this could be a symptom of a failing LCD display (or CRT tube, if you're using one of the older styled big ones). one way to test for sure though, is if you have access to another computer (whether it be desktop or laptop, shouldn't matter) and hook it up to that one and see if the same thing happens. If it does, then you know that your monitor is at fault. If you are within manufacturer's warranty you can usually get it repaired through your place of purchase, or directly with the manufacturer themselves, but if not, then repairs are usually not worth it, and will probably cost more than the monitor is currently worth.

Once you get a dead pixel (black dots), there is no way to repair that part of the screen

I wish I could post a solution, but I don't have one. I too have a Magnavox. About 6 months ago, once every 2 weeks or so, the screen would just go black- all but an inch or two on either side. Now, it seems like it's a weekly thing, sometimes every hour or two. As of tonight, it has happened twice in a matter of thirty minutes. It usually repairs itself if I turn it on and then off again but that's just not working anymore. If anyone has a solution, let me know.
