So, I just plugged in my new Toshiba 40" LCD tv, model 40e200u, and I have a constant running horizontal stripe in the back ground, spaced about 6" apart when viewing the RGB/VGA input(my computer).

I replaced a samsung 32" with all the same specs and didn't have a problem when it was hooked up. It only has 60 hz refresh rate, which I know isn't top of the line, but like I said was not a visible problem with the other tv.

Side note, box was beat up pretty bad, damaged corners and two holes in the box. Since it isn't doing this when watching cable input, I really don't think it actually damaged the tv.

I plan to use this tv for cad drafting a good bit, but the line is pretty annoying. Anyone have any advice?

Re: New TV with running Horizontal Lines

If you're using a 15 pin connector - check that none of the pins are pushed in...
one monitor may be more forgiving of a marginal connection.

Have you tried any other video input to see if it has the same issue ?

Are they both (the PC and the TV) on separate power circuits?
Yes, as was the original configuration with the last tv.

The video card actually offers the hdmi and the tv has it, but I haven't gotten that cable yet. Right now I am going from digital to vga, then vga cable to tv. Same configuration on the other tv.

Thanks for the responses thus far.

Re: New TV with running Horizontal Lines

If what you're seeing is multiple horizontal bars of "fuzziness" moving slowly upward through the picture, you have a ground loop or related ground problem.

More succinctly, you're getting 60Hz line hum impinged on the video signal.

Interesting. That sounds about right. Not sure where the problem is coming in. Computer is a couple months old with a top of the line video card in it. I will try a new cable before I give Newegg any grief.

Re: New TV with running Horizontal Lines

Problem identified. Livesounder, your post got me thinking. Had a small space heater turned on at my feet. Turn it off and it fixes the problem. I don't recall having this problem with the other tv. Guess I will need to run an extension cord to another circuit if I got with the current setup. Thanks for the feedback.
