Thin Horizontal lines

Hi!
I have a beautiful DVD picture but I notice very thin lines on the right and left sides of my Mitsubishi monitor, They don't detract very much from the picture and they're not always visible, but I know they're there and I wonder if anyone else has had this problem ?? This isn't a case of The DVD copy protection thing and I'm pretty sure it's something from the monitor. Could someone help???
Thanks!

Shelly,

Could you give us a little more information? When you say Mitsubishi monitor, are you referring to your Computer Monitor, or your TV? In either case, if you can get us the model of the unit and the equipment you are using to view the picture it would greatly help us to answer your question. Also, are the lines running horizontal or vertical? Are the lines only displayed when playing DVDs?

I can think of a really common case that I've seen this in Computer Monitors... The Sony trintron tubes cause a very light horizontal line to appear on the lower half of the screen (two lines in the larger 19" and 21" monitors). In the case of the Sony, you can only usually see this when displaying a clean white background. This might be the case on your screen. However, without more information this is going to be a tough question to answer.

Thanks for your speedy reply!! The Mitsubishi monitor is a TV monitor--31 inches---I don't know the model number offhand but I can find it --I'm at work now-- but the lines are horozontal and only extend a few inches. My player is a combo Pioneer Dvd-Laserdisc player-a 909--I think and the lines are also visible on laserdiscs.
Thanks!

Shelly,

Once I get the info on the model of the TV, I can be a little more specific but...

What kind of inputs are you using to the TV? Componant, composite, S-video, Coaxial? Are the DVD and the LD using the same inputs? By chance are they using a split input? Do you have this problem with normal broadcast television or VHS?

I don't know if it is the same thing or not, but I have a Sony TV and a Sony monitor which both have two horizontal lines near the top and bottom of the screen. I thought that it was just a burned out row of pixels or something for a long time, but then I read in the manual that they are small wires needed to hold the screen in place. I think this is only neccessary on the newer flat screens. Again, I'm not too sure, but this could have something to do with it.

Do the lines start at the edges? Or in the center.

Does anyone know if Mitsubichi TV's use the Sony Tube... I think that it is the same style.

If so that probably is the shadow from the stabilizer wire... but only if it goes all the way across. Maybe check. Get something that is mostly white or gray and see if it goes all the way across. On my Sony TV the lines are harder to see in the middle for some reason.

In terms of the horizontal lines they definitely start at the left, don't go all the way through and sort of remind me of fingerprints or--if this makes any sense--a reflection of light coming in through a venetian blind... will try to give more information. I have to stress the picture still looks great and when it's dark you can't see it at all but it's still slightly bothersome....
By the way, thanks for all the replies!!
Shelly

one addition--the lines are at the left and right and only at or near the top.

Venetian blinds... Hmm. Could it be that you're seeing the effects of the DVD-player turning a 16:9 enhanced picture into letterboxed widescreen?

Do you watch movies in full-screen or widescreen? If the latter, try one of the following procedures:

1. Go into the player's setup menus and set your DVD player to 16:9 mode. (The manual should tell you how to do this if you're not sure.) Pop in a disc with 16:9 enhanced widescreen picture (almost any Columbia- or Warner DVD should do). The picture should now appear stretched vertically. If the artifacts are gone, the problem is the player's downconversion.

2. Fullscreen movies won't display any down-conversion artifacts. Make a comparison between a fullscreen and a 16:9 widescreen DVD. If the artifacts are gone on the fullscreen version, it's the down-conversion.

The only solution to this problem is to replace your DVD player with another brand or a newer model, or live with the artifacts since they're not really a 'fault' with the player - it's just the way it's designed. If this becomes necessary, check out the player in the store before you pay for it.

BTW, what player do you have? (Brand and model)

Please forget everything I just wrote...

I see you already told us what DVD player you own. Also, if the artifacts are also visible on laserdisc, it's not the downconversion, since laserdiscs don't do downconversion...

Maybe I'll start reading the posts more thoroughly from now on.

Shelly - Did you get a chance to read my last post to you? What is the model of TV that you have?

Just a little side note, it does sound an aweful lot like the thin wires used to hold the screen in place.
