    Same problem with vertical lines after working fine for 5 years. Problem sometimes clears after a long warm-up but usually doesn't. Ran all the checks I could find (monitor trouble shooting guide by Microsoft found on-line) but nothing helps. Also see horizontal lines around cursor.

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!

Why does my monitor have colored vertical lines?

Hi Shannon,

I don't have good news for you. Coloured vertical lines is a symptom of terminal failure of LCD screens. Most common in laptops, monitors, and TVs. Problem only gets worse with time with more lines appearing, then expanding to cover a whole side of the screen. 30 - 50% normally.

Your monitor has probibly suffered a power surge at some stage those vertical lines are (kind of) dead pixles.
What it actualy is is the controler chip in teh monitor is slightly cooked sending the wrong voltage to that row of pixles, hence you get teh wrong colors displayed and they can vary in strength depending on what your looking at at the time.
I am sorry to say that the only solution is a new screen most warrantys dont cover that type of problem, and you can only guess what i think about that attitude some companys take.

Vertical lines

The monitor sounds like its going to die. The problem is because of the LCD Panel.

A monitor should have 2-3 boards, a logic board, an inverter, and a power supply
Lastly the LCD Panel which should consist of a crystal mirror, LCD Panel(has the circuitry and the brains for information/images that display), and backlights.

The LCD Panel is the problem. It needs to be replaced.
Yes it sucks, but usually LCD monitors last for so long, but in some cases they wear out by use and the thin circuitry that provides the power to create colors and images, begin to die. Im sorry. Its really the only solution unless you have the expensive equipment used to make the panels.

My recommendation is to replace it and it should work spankingly new.

I wish yuo luck. Please Rate.

Vertical Lines On Display

First, plug a external monitor and toggle the screen to discard configuration or software problems. If the image shows correctly you have either a problem in the LCD screen or its connection cable.
Open the cover and check for loose or damaged cables, specially next to the hinges. The next thing to check is a new LCD screen. You can have replacement parts and instructions here:
