    Same problem, except lines are on the far right of the screen. Lines are there even with the monitor is not connected to the computer. Does this mean the problem is in the monitor? Hardware or software? Thanks.

Samsung dispaly .it showing two red colar lines on the moniter.it s like vertical lines. tell me the soultions


If there are vertical lines that do not change color then it sounds like dead pixels on the monitor. There is not really a way to repair it, nor is it really cost effective if it was, considering parts/labor will exceed the cost of purchasing a new monitor. Your best bet is to check if you have a warranty on the monitor and get it serviced. Otherwise, you'll just have to either put up with it or purchase a new monitor to replace it.

Good luck!

Hi my monitor has colored horizontal lines all over the screen i have tried checking all the connections .....no change plus the lines are still there when the computer is not connected to...


This is bad news, the problem is the screen panel itself, replacing the display would exceed the price of a new monitor. It is far cheaper to buy new, than to try and fix a unit that will cost an arm and a leg.

I have vertical colorful lines on the screen just got a new computer with windows vista


the monitor is bad if your getting vertical lines on it. Anytime you get vertical lines on any monitor, LCD, laptop LCD, etc, then that means the screen is bad.

Your monitor needs to be replaced.

Monitor: Compaq TFT5015 Displays vertical lines


Check that the signal cable from the computer is firmly connected and that there are no bent pins in either end. If the trouble continues, the problem is in the monitor itself. Given the low replacement cost, it's uneconomical to try repairing these.

Vertical lines appear on my lcd monitor


Hi
I am a Dell Certified System Engnieer(DCSE)

you have to be sure if its an issue with the screen or operating system or video card
what you have to do is
turn off your system
now the moment you turn it on again start hitting F2 key
you will get system setup screen
if you see those lines here as well get the LCD replaced and if there are no lines
then try installing the latest drivers
or else you have to get the parts replaced
either the screen or video card
but in case you get display fine in system setup
its for sure your display is fine

Mag innovision LT716s monitor


When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.

Vertical colored lines


I had the same problem with my monitor, saw only coloured vertical lines. I opened it, opened the back of the metal casing to get access to the circuits. There I found a loose connector. I reset it and it worked again!

Screen goes black with bright white horizontal line


This problem of loss of vertical deflection with the line offset from center suggests a cold solder connection in the vertical sweep circuit or in the power supply to the vertical sweep circuit. Most service shops should be able to fix.
