Hello,

I suggest that you check the connection of the motherboard and your computer's screen because it has something to do with it. Or if resetting the connection won't do anything then I suggest that you let a tech check it.

Open case screws


You should open your computer and reset the data cable which connects the motherboard and the screen. If it's not going to fix it, then you would need to get a technician to look at the motherboard and the LCD so that he can identify which part is causing the problem.

Vertical strip of flashing horizontal lines on Acer Aspire 7551G screen


More than likely it's the lcd screen and will have to be replaced. I could be the video card, but most likely the lcd screen especially when you can put pressure on the screen and cause changes. To isolate the problem try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the laptop. If the Borrowed monitor displays ok, then the problem is with your lcd screen and the video card is ok. If the Borrowed monitor displays the same as your lcd screen then the problem is with your video card inside the computer.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Once you narrow it down to the lcd screen as being the problem you might try taking the lcd screen apart to reseat the lcd cable on the back at the top of the lcd. Just unplug it and plug it back into the connector. You can also try doing the same where the lcd cable plugs into the motherboard. Just pull it out and put it back.

My laptop monitor has vertical lines all across it, so I have an external monitor, how do i connect it to the laptop


Connect the VGA cable to the VGA port of the laptop then restart the computer.
Go to display properties and enable the second screen, then disable the notebook screen to display only on the external screen.

Broken screen, external monitor via VGA won't


Press "Fn+F7" once, wait a few seconds, and press it again, to "cycle" through all the possibilities (LCD-only, VGA-only, both).

Try the monitor with some other computer (desktop or laptop) to see if the monitor works at all.

Restart your computer -- does the initial "splash" screen (showing CPU speed and RAM-test) show? Does the "Windows" screen (with the crawling worm) show on the external monitor?

Laptop screen displays vertical lines of various colours


Have you tried to connect your laptop to external monitor?
If you get normal picture on external monitor, then you need to replace LCD screen, but if you get same picture on external screen, then unfortunately you will need new motherboard, because graphics card is integrated to motherboard.

Coloured vertical lines down lcd screen


To isolate the issue, i strongly recommend to connect the notebook to the external monitor by VGA port which had BLUE colored on the notebook. So that if it is normal then you need to confirm the issue is with the LCD display.

Inspiron 1150 lines on screeN problem.


Connect an external monitor to the laptop and see if it also has the vertical lines. If the external monitor looks fine, then your laptop’s LCD display panel is bad. If the monitor has the vertical lines displayed on it, then your graphics card or motherboard is bad.
