TFT Monitor has horizontal coloured lines and patches
I moved house 10 weeks ago and did not set my pc up for around 10 days after the move. When I set it up I found that the screen had horizontal coloured lines (like pages in a book in some parts) with a patch of 'ripped' looking black and white. I am far from 'at home' with pc problems and just want to know if perhaps the monitor was damaged during my house move or if it is something that can be fixed by myself. HELP THANK YOU

Hi my LG 47ln5700 tv set has thin greyish black horizontal lineson one side of the .... I hope this works good with Samsung LCD as well....
It could be 1 of 2 things, either your monitor is going out on you, or your graphics adapter is going bad. Depending on how long ago you purchased it, and from whom, I would contact Dell service to find out if they can return it, or give you any suggestion.
Sounds like the LCD is failing/failed. Hook up a desktop monitor and see if you have the same problem.
Replacing LCDs is not trivial. Here is a site that sells them.
Google LCD replacement and you'll find many sites.
Some monitors don't give orientation feedback to the video card to auto change the orientation when you move from a horizontal screen to vertical. what you need to do is get to display properties and advanced settings (right click desktop > properties > settings > advanced > video card settings > orientation) - you should find an option to change the orientation of the display - correct it accordingly. if the settings are not being saved after you restart, you need a video driver update - find it on your manufacturers website.
To my knowledge, it is not the zoom that has to be adjusted but rather the horizontal width, zoom would expand all (to, bottom & both sides) whereas your only concern are the two sides.
Should the horizontal width not fully expand, then there is an internal problem with the horizontal deflection circuitry which could either be the yoke, a capacitor or shunt diodes. In certain instances, a below normal voltage at the mains or the internal power supply could also cause this.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
now only visible in a thin horizontal line.
first of all you reduce brightness to monimum.
it just to protect your tv from crt demage.
your problem is in horizontal output section as you have mentioned that week or so ago the right and left bottom edges of the picture began to move in like a sideways triangle filled with black so this sympton is due to hor. section problem.
your flyback transformer or horizontal output might be defective.
but remember check for power supply is ok from
hope this will help.
