Vertical lines on my laptop lcd

Compaq M2013AP
October 5, 2008 at 17:05:54
Specs: MS Windows XP Home, 256mb

My laptop's lcd has been coming up with
these vertical lines that keep on increasing
everyday. It started with a single line from
the right side and till last count has
increased to 24. I've attached a photograph
of the screen. If I try to take a
printscreen, the lines do not appear and a
normal desktop photo appears, thats why I
took this picture with my digicam, please
help...

Your link doesn't work.

Do you get the lines while booting too?

Try this.

Remove any bootable CD or DVD, press F8 repeatedly while booting, don't hold down the key, choose Enable VGA mode from the boot choices menu.
That loads Windows normally except it forces Windows to use default VGA drivers that all video adapters and mboards support.
Try the computer for a while.
- If the lines do not appear in that mode, you probably have a problem with your video drivers - un-install them, in Enable VGA mode or in Normal mode, then install them again. The proper video drivers are in the downloads for your model on the HP web site.

- If the lines appear in that Enable VGA mode in the same way, you probably have a hardware problem.
Since it last worked properly...
Have you EVER spilled liquid on this laptop, or has been exposed to liquid such as rain?
It doesn't matter whether it was running at the time or not - the ATX mboard is always powered in some places as long as the main batterry is in the laptop.

Has this laptop EVER been dropped?

Do the lines appear and disappear depending on what position the laptop lid is in?

- if your laptop has a port you can connect a regular monitor to, connect one and try your computer for a while.
If you get no errant lines, there's nothing wrong with the video adapter or the drivers for it - the problem is between the video adapter and the LCD display, or in the LCD circuits, or the voltage inverter for the backlight in the LCD display is faulty.

I'm 99% sure it's a flaky connection between the panel and the motherboard, connecting your laptop to a monitor will confirm this either way.

Definitely sounds like a hardware issue to me. The screen
could be reaching the end of its life (is it relatively new?) or it
could be a fault with the video and graphics card.

If its taken a physical blow of any kind, that's obviously all it
takes to scramble the screen. I remember a friend dropped
his laptop and it was lights out in one brief lapse! The display
flickered a bit but it was horribly messed up and the actual
graphics connection on the board had been shattered. Last
he got to use that laptop!

This will confirm only that the video card is working properly or not,you dont need the LCD connected to a laptop to use an external monitor. The Lcd could still be an issue, I would try to reconnect the Lcd cable.

Thank you all for your prompt replies. I got
access to an external monitor and checked the
display. The display on the external monitor
is absolutely fine. I guess its a hardware
problem then hun !

This laptop is a bit old now, its more than 3
years old, has travelled a lot and has seen
its ups and downs. So, I guess its just old
age.

Is there anything that I can still do to try
and resolve this issue. Can the lcd be
repaired or changed ? Any idea about the
costs involved?

Thank you all once again.

In that case, your problem is probably
- the wiring between the base and the display is damaged, often right where it passes through the hinge
- and/or - the circuits in the display assembly are damaged.

You do not have the symptoms of a failing backlight or a failing voltage inverter that supplies high voltage to the backlight.
Your lines problem probably cannot be caused by software problems.

The wiring between the base and the LCD display is a frequently replaced item and relatively inexpensive to replace.
You could try that first.
If you're handy you could replace it yourself.
Local places authorized to work on HP/Compaq laptops may have it in stock. If not, they can look it up for you, or order it for you.

The complete display assembly is a lot more expensive. Local places usually don't have it in stock. If it was used in many models you may be able to buy it new for a reasonable price, or for less money a used refurbished unit (usually it's backlight has been replaced and in that case it will last as long as a new display).
If you're handy you could replace it yourself, but it's a more complicated task.

You may be able to find a used display unit that is not refurbished, or a laptop for parts, for less than the new or used refurbished display assembly costs, but then you're probably getting a display that will not last as long (the backlight has a definite limited lifespan).


Look on the HP site to see if there is a Maintenance manual available for your Compaq model or model series - usually there is.

Go here to look up the parts for your model:
http://partsurfer.hp.com/cgi-bin/sp...

Use your model to search with - you may need to use the specific product model number found on a label on the outside of the computer - it's probably on the bottom.

If you are able to look at both a Maintenance manual and the parts list, you should be able to figure out the part numbers of what you need.

You don't necessarily have to get the parts fron HP. Once you have found what part number you need, search the web and there are probably vendors that have it for less.
