Display has gone bad with fine vertical pink lines

Suddenly failed and lost resolution on screen. White lines appear on start up screens and pink after boot up with green lines on black background. Seems unstable with flickering. Hoping I don't have to change the motherboard, but need some help with this one.

I have a Toshiba Satellite 5205 s703 running XP SP3

Thank you,

Tim

    Thank you Geekman!

    External monitor has same display problems, so I guess it's the graphics card on the motherboard. Can I inspect it visually for signs of loose connections??

    Thanks again for your help!

Connect an external monitor to your laptop, if you get a clear image on this monitor the the video card in the laptop is OK.

The fault could be a defective inverter that supplies high voltage to the CCFL lamp or a faulty CCFL lamp. Most likely a faulty CCFL lamp.

Defective CCFL backlight may has the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) as reached the end of the life and all you need to do is replacing the CCFL lamp

The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

    The graphics card/chip is part of the motherboard, there are no wires other than the video cable to the LCD screen and the video card is not possible to repair. The only option is to replace the motherboard or buy a new laptop.

    You could remove the hard drive from the laptop and insert it into a USB drive case and use it as an external hard drive for backup and file transfer..

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.

Hi,
There can be two things that's causing this problem. It could be that your Video Adapter for this laptop is starting to fail or it could be that the ribbon connectors for your lcd is loose or not working properly.
Take it to a local shop to have i checked.
Hope this helps.

Vertical lines on an LCD screen are not a good sign. This usually means that your screen is going bad.

Screen is disclored.Shows pink instead of white.


Possible bad connection on the LCD cable. Check and reseat the cable on both end( the cable to the laptop and the cable to the LCD panel). If that doesn't work you will need to replace the cable.

You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

A pink vertical line appears suddenly on the screen


Sounds like a hardware problem. You should probably return it as soon as possible.

LIGHT BLUE VERTICAL LINE ON MONITOR


The vertical line is a bad pixel sensor at the edge of the screen, your screen has hundreds of vertical and horizonal pixel sensors. This is an indicator that the screen is going out and need replacing.

Two vertical lines on my compaq presario (M2000)


Hello,

Try changing your screen desktop resolution to a different value. If you still have verticle lines, then try changing the color depth from 32bit to 24 or 16. If the problem remains your display adapter has completely failed. It has failed to compute column row addressing math.

Naturally, you would want to find and install the latest drivers for your display adapter with the hope that the failure is in the software driving the display adapter and not an onboard chip. If updating your drivers fails to resolve the issue you need to have service performed on your laptop. Most laptops have the display adapter soldered on the main circuit board and many shops are capable of replacing this chip set.

Yet, get a quote first as the cost might cause you to consider an upgrade into a laptop that has a display adapter that is Direct X 9c or Direct X 10 ready as that will run most of the new game titles coming out this year.

Let me know if you have any further need of assistance as you run through the above troubleshooting routine.

I do hope this has fixed ya!

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
