When i turn on the monitor, it is covered in vertcal lines. It still loads to the opening screen but the lines are covering the entire screen and are yellow. I can barely see anything on the screen. This just happened after having the monitor work fine for 4 years. Any ideas?
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!

TV Repair help with troubleshooting lines on your TV Screen. ... hi i have a sony bravia mdel # KDL46EX523. i have horizontal multi colored lines ... My TV has the following symptoms: - Horizontal lines from top to bottom of .... thick(like 1-1/12 inch) and a couple of green vertical lines next to the black one.Missing: kdl 40bx421
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.
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.
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:
