Screen has vertical lines in the display

The screen has vertical lines in the display. They are noticible when you have a solid color displayed, but when there is lots of motion they are not as visible. Its easier to see with a red background. Bulb has less than 400 hours on it, filters are cleaned regularly.

Vizio P50HDTV Display Problems - Colored Vertical Lines .

1 Answer

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.

This problem is caused by a defective LCD display. It is a common problem too. The only way to repair it is to replace the LCD display.

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.

Lp70+ display shows a solid black vertical line
the light tunnel is either collapsing and blocking the light going through it (and needs replacement) or the vertical/hoizontal adjustment of the tunnel. if you take the lamp out and move the colorwheel (with a pencil eraser) to the clear section, you should be able to see a square through it. if part of the square is blocking the middle, the tunnel needs replacing.

by the way, on some projectors the light tunnel is called an integrator rod.

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
