Laptop screen blank all white

Either your LCD Video Cable is not plugged in snuggly or the monitor is slowly going bad. The fact that you can see the images on an external monitors says your Video Graphics Card is working fine. You'll need to disassemble the laptop to get to the cables. Get a quote from your local computer shops, then try the guys at: Most times they will fix it and ship it back by Fedex or UPS cheaper than any quote you obtained including the shipping.

My Compaq presario CQ42 has a white-red thin line at the right corner of the screen. Is it a problem to use the laptop with it before I fix it.


If you see a Vertical/Horizontal colored lines on your LCD, that means either the Video Card, LCD, or the LCD Flex cable (this is the cable that connects your motherboard to your LCD screen) are going bad and needs replacement. You can still use your laptop though but I strongly recommend having it fixed ASAP before it gets worse. You're still under warranty, call HP/Compaq at 1-800-652-6672.

Good luck.

From yesterday i have been getting this streak flash type of line on the bottom of my screen ....being display in every 2 secs or white in color l though its not hampering the operation of the...

Your most likely cause to the color flash on your screen is a bad LCD panel. One way to troubleshoot this is to hook an externa monitor up to your laptop, and observe the display on the external monitor. If it is ok, then your LCD is the cause. If you still experience the flash, you could have a motherboard video problem, but unlikely.
There is no easy fix to get rid of the flashing line. If your laptop is still under warranty, or even close, I would contact HP /Compaq customer support and explain your laptop's problem.
Hope this helps !

I had a vertical line on my laptop screen

A line on a LCD screen (like a laptop) is caused by a faulty power connection in the screen.

Usually a entire row or column will not activate causing a black line to show. When you closed your laptop, the screen is powered down. When you opened it back up, the screen would be reinitialized and it appears that you lucked out on your issue.

When a row or column fails it is usually a permament failure that can only be fixed by a monitor technician or a screen replacement.

A similar failure can happen that causes black dots to show on the screen. These are burnt out junctions where the rows and columns meet together. The dot is commonly called a pixel.

Hi there. i got a problem with my laptop lcd display. at the bottom of the screen is a line, usually white blurry lines. sometimes this line shows a portion of the upper screen. what's the problem? is it...

Hi Rhyecho,

Your problem could be one of several things...

1: Go to or (They're one in the same) the video/display drivers for you're particular model and operating system and reinstall them. If that doesn't solve it....

2: Hook the laptop to a standard monitor (desktop) via the blue VGA out in the rear of you're machine.

Once you turn the laptop back on see if you get the same symptoms on the other display, if you don't, in all likelihood you've got an LCD problem. If you do get the same symptom its probably related to the video chip (or other problems on the board).

Additionally, If you still get the line on the other monitor you could try this, Depending upon how brave and or experienced you are, on rare occasions the cable leading from the motherboard to the monitor may not be seated properly and could be causing the problem. But you'll have to remove to keyboard to find out. (The screws to do this may or may not be marked with keyboard icons on the underside of you're machine).

Unfortunately, It sounds like you're problem is probably on the board though.

Either way good luck.

Two vertical lines on my compaq presario (M2000)


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!
