Occasional colored vertical lines on the screen at startup

Once in a while when I start the computer, the monitor displays brightly colored vertical lines of differing widths. If I power it off and on a few times, it has eventually booted up normally. Does anyone know what the problem might be or if it is serious or not?

Base on our experience.... you are looking at a possible screen problem. Is it serious? yes as the screen replacement costs almost half of the total cost of the laptop.

but no harm trying this

1. remove the screws from the LCD bezel, remove the screen
2. detach the cable and reinsert them all both the inverter and the flex cable.

inverter is the circuit usually located at the bottom of the screen and the flex cable is the ribbon that runs from the laptop to the back of the lcd.

reseat them and see if your display improves

Display shows lines and color not displayed properly


A line vertically down the screen (usually bright green) is a failed column strobe. This can be caused by the connections at the top of the screen failing or the strobe chip starting to die.

Random colours can be caused by a cracked screen or a failed video card.

Best to take it to a repair shop for it to be assessed.

My Samsung n120 screen is displaying only vertically - how do I go back to horiz display?


Computer users occasionally have a need to rotate, or "flip," a monitor display to be better able to read long documents or to view pictures. Because rotating a computer screen is such a basic function, modern operating systems (Windows XP and up) include hot keys and display options that enable the user to rotate the computer screen by 90, 180 and 270 degrees. Rotating the computer screen allows for more display options. For instance, when rotated 90 degrees, a 1680x1050 monitor becomes a 1050x1680 monitor, which provides more vertical pixels than a standard display.

Windows XP/Vista Monitor Orientation
Minimize any windows or programs to the taskbar. Click the desktop. Press "CTRL" + "ALT" at the same time. Press one of the arrow keys to flip the monitor orientation by 90, 180 or 270 degrees. The left arrow rotates the computer screen 90 degrees; the down arrow rotates the computer screen 180 degrees; the right arrow rotates the computer screen 270 degrees; the up arrow resets the monitor orientation. Rotate the computer screen in Windows Vista by opening the Control Panel, searching for "Tablet PC" and changing the "Orientation" drop box to the desired rotation. b> Windows 7 Monitor Orientation b> Click the Start menu at the lower-left hand part of the screen, and open the Control Panel. Select "Display," then click "Change display settings" from the left column. When using multiple monitors, select the monitor that you would like to rotate. Click the drop box next to the "Orientation:" option. Select the desired rotation and click "Apply." Click "Keep Changes" or "Revert," depending on preference. Click "Apply" in the Display Settings window. Click "OK" to finish.

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.

Try taking out the Ram memory first one stick at a time. Sometimes when Ram goes bad or overheats, it first affects the display. If that is not the issue, here is the link to your service manual.

Blue Vertical Line


It is sounding like when the laptop is turned on and heats up a bit, the line appears? Sounds like one of the panels is going bad or atleast has developed a problem. below are some tricks you can try to lessen the annoyance of the line. Dual-Scan STN displays are composed of 2 panels behind a single protective panel or screen. Because you are looking through the protective screen the display appears to be one large panel even though it is not. There is a physical separation line (gap) at the point where the two panels meet. When the computer is on and being viewed it is not unusual to see the visible separation line with the Dual-Scan STN displays. The line, actually the fine gap between the display panels, appears because the color and light pixels cannot run along the very outside edges of the panels. This line (gap) between the panels can be seen as a fine gray line and is most noticeable when viewing on a screen with a white or light background. Note the line may not be as noticeable when the screen is displaying certain colors or darker backgrounds. SUGGESTIONS: It is not possible to completely eliminate the line but there are some things you can try to reduce it's visibility. 1) Lower the display brightness/contrast. The brighter the backlight the more noticeable the line. 2) Use Wallpapers and Screen savers that use darker colors. 3) In the Control Panel/Display applet under appearance try different combinations of color schemes for your Window and Background choice Let me know what happens. Good Luck, Tim
