HP pavillion dv 9500 monitor problem

After 1.5 years of usage bad pixels appeared on the left half of the screen.
But thay are not dead at all, thay just blinking with violet color when they must be blue or a red color when they must display an orrange. Aswell they blink violet on the work space of 3DSMax (grey). This problem appeared in a moment and i could not solve it by reinstalling video drivers or DX.

    I have a HP Pavilion dv9740us with the same problem. I have had it about 1 year and have not had any problems with it at all. It worked fine the night before went to use it the next morning and some of the screen colors are violet flickering and the blues are flickering. Does any body know what the problem is.

    I found out that it is a problem of a screen controller. It could be solved only by replacing the screen.

Plug in an external monitor to your laptop. Is the picture Good on the external, or is it torn like on your LCD?
If it is good on the External, then you need to buy a new LCD and replace yours. If it is bad on there as well, then chances are your video card has gone south. With your model laptop, you will need to replace the motherboard to repair this issue.
In both cases, Ebay may be your friend, as HP is rather over priced on their repair parts.

SOURCE: HP pavillion dv 9500 monitor problem

If the unit is in warranty or your inexperienced with opening notebooks, you should send it in for service.

If you have some experience with repair of notebooks, I would try reconecting the LCD cable to the mainboard first. If that doesnt work, I would go for a new LCD cable. But it might also be defective conectors on either the mainboard or LCD panel.

Be warned tho. The LCD bezel and the bottom screwholes on the LCD assembly break very easily on these models.

If you provide me with the modelnummber I can find the partnumber for a replacement cable. The modelnummber is written on a white lable under the unit. It should look something like this AA111BB#CC.

If a new cable doesnt fix the issue I would recomend you send it in for service anyway. As you dont want to spend to much money on parts troubleshooting.

Blotted screen in my hp laptop


1.Locate the problem pixel. Display a true black image on your HP's monitor. You can do this by playing a DVD on your HP laptop, and pausing it on the black screen just before the movie starts. Once you bring up a black image on screen, the stuck or dead pixel should be visible.
2.Try applying direct pressure to the problematic pixel. After you've located it, turn off your laptop. Place a soft cloth or rag over the pixel to avoid damaging your screen. A soft chamois works well. Using the tip of a pen, apply gentle pressure to the pixel. You don't need to press hard, as too much pressure can crack or scratch your screen. While applying pressure, boot up your laptop. This should force the pixel to begin working properly.
3.Tap the pixel. With your Toshiba booted up and an image on the screen, gently tap the pixel with the rounded end of a pen cap. Tap hard just hard enough to see a small white flash on the screen. Tap your HP's screen until the pixel begins working properly.
4.Download a stuck pixel program. Several programs, including JScreenFix, UDPix and Pixel Protector, are available for download and can help fix a malfunctioning pixel. These programs display rapidly changing colors and images on your screen. The flashing colors and images can force the pixel to begin functioning properly.
5.Contact HP. If none of the above methods work, your screen may have a pixel that is truly dead. If that's the case, the only option is to replace the display completely. Contact HP customer support at www.hp.com to find an authorized repair service near you.

Hi, i have AL1716 monitor (2 year old). Recently, there is a blue vertical line which appears on and off sometimes in the monitor. Can anyone suggest on a solution


Is the vertical line always at one location ? (on the screen)
If so, it appears that the video card/driver (on your PC or laptop) may be causing the line to appear occasionally ... i.e. flaky ... and it will likely fail (completely) in due time. To confirm it's the video card, try using another monitor (long enough) to see if it happens.
[ The line may also be caused by "dead" pixel on the screen ... but this usually happens on randomly located pixels on the screen, not on one vertical line. But, it may also be a possibility ... in which case, using a different monitor may prove it one way or the other ]

Blue vertical line


The lines appearing on your LCD means it has a defect on the screen.

There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color

You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.

2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.

3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.


If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost

Please rate this if it this helps.

Display is not coming , black screen is there


If you get zero display at all check if you can hook up an external monitor first to determine if problem is with screen or video card.
If display can barely be seen that is practically black but you can just see it in bright light check brightness levels of screen i cranking them up fails then you need a new screen backlight. Talk with hp about repair.

Laptop monitor is black


The fastest way to eliminate the video section of your PC is to use the VGA port with an external monitor. If you can get any kind of video, then the problem is narrowed down to either the fluorescent backlight itself or the inverter that supplies it with high voltage; neither of these have any influence on the video output to an external monitor. The LCD section itself can't really fail at once since it is made up of tiny pixels and while it isn't uncommon for indivdual ones to fail, the likelihood that all fail is very remote.  
The problem is; without some technical skills, it would be tough to pin it down to one of these two. The backlight tube is a specially formed fluroescent and if it appears to be blackened at either or both ends, then the tube is dead. If it appears pristine, then the inverter is dead; this is normally a small board apart from the main board and not too bad to replace.
Accessing the backlight is of varying degrees of difficulty and if it isn't done carefully, you could damage the LCD portion.
If it seems to boot OK, if you peer at the screen from several shallow angles, you should be able to see some 'ghost' activity on the screen.

I have an HP DV9074CL Pavilion laptop that won't boot


I bought mine in April 2007. This happened June of last year and they replaced it for free. It just happened again 2 nights ago and HP won't do anything. My fiance called them and got a case manager and said that they design their laptops to work for only 2 years to which I say if it's designed to work for 2 years, shouldn't my motherboard still be working? After this experience and numerous other problems I have had with this laptop, I am never buying an HP product again.

Vertical white line on laptop display


Yes, this is a defective screen. The only fix is to replace the screen. It's called a column of dead pixels. Since it is under warranty, contact HP to have them warranty it out or take it back to the place you purchased it from for an exchange. Please take a moment and give this answer a good rating of fixya. Thank you.
