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

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.
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. Check out www.lcdparts.net
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.
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.
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.
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.
