More than likely it's the lcd screen and will have to be replaced. I
could be the video card, but most likely the lcd screen especially when
you can put pressure on the screen and cause changes. To isolate the
problem try connecting another monitor to the computer. Borrow a
monitor from a neighbor, friend, relative or co-worker and connect it to
the laptop. If the Borrowed monitor displays ok, then the problem is
with your lcd screen and the video card is ok. If the Borrowed monitor
displays the same as your lcd screen then the problem is with your video
card inside the computer.
Plug in an external monitor and see if the
display shows up on it. It can be any kind of monitor even the old big fat crt
monitors as long as it has a vga cable to connect to your computer's vga
port. If so that proves your video card is ok. The video will show
on most systems when you reboot without you having to do anything. Some systems
will require you to hit the FN (Function key) + F1 thru F12. Hold down
the FN key then hit the correct key for displaying on the monitor (F1 thru
F12). The correct key will normally have CRT/LCD on it or it will have
the icon of a display.
Once you narrow it down to the lcd screen as being the problem
you might try taking the lcd screen apart to reseat the lcd cable on the
back at the top of the lcd. Just unplug it and plug it back into the
connector. You can also try doing the same where the lcd cable plugs
into the motherboard. Just pull it out and put it back.
Try plugging an external monitor to your laptop and see how it displays on it. It can be any kind of monitor even the old fat crt's as long as it has a vga cable that will connect to your laptops vga port.
If the display does not immediately show up, then you will have to hit the FN (Function key)+(F1 thru F12) to show the image. Press and Hold the FN key then hit the correct F1 thru F12 key. The correct F1 thru F12 key will have either CRT/LCD written on it or it will have a display icon on it.
If the image displays correctly on your external monitor, then you will need to replace your lcd screen.
Laptop screen display problems occur for many different reasons. Some issues need professional attention, but others can be repaired by the owner. A screen that displays vertical lines often means that there is a problem with the video cable connection to the LCD screen, or the cable itself. In order to repair this problem, the display screen must be disassembled. If you feel confident that this task is within your realm of expertise, follow the steps below to remove your laptop's LCD panel and fix the vertical line problem on your laptop screen.
1. Remove the rubber seals covering the screws on your screen's outer frame using a flat-head screwdriver. Remove the screws, then carefully pry the frame from the screen using your fingers. Release the plastic latches holding the framing in place, then remove.
2. Remove the screws holding the screen to the support brackets. You will see the video cable, which is attached to the back of the LCD screen. Try unplugging and reconnecting this cable, making sure that it is seated properly. If the problem was the connection, this may solve the vertical line issue.
3. Turn on the laptop. Move the video cable around a bit, without moving or touching the screen. Check the screen to see if the display image changes at all. If it does, the problem may be with the cable itself. 4. Move the laptop screen around to see if this affects the display. If so, the problem is most likely with the LCD screen itself, not the video cable. Replacing the screen will be necessary.
This the problem related with LCD. Horizontal and vertical line occur, the cause of LCD data strip disconnected. If you are able to open the LCD bezel and back cover then look display data strip that is connect with LCD. if you need more then hit me mail,I'll be online on fixya.
Do a power drain, this may cause by an electrical charge in the motherboard itself,Im Not really sure how it affects the display of the computer but this method usually fix such problem like that, First, removed the battery then unplugged the AC adapter the press and hold the power button or the ON/OFF button for at least 30 seconds then connect the power supply back to your computer then turn it back on, if nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...
Hope this will help...Your response is very much appreciated...
Before you do anything else, using your own (or a friend's) external monitor, connect your laptop to the monitor and see if the display looks the same as your laptop dos. Sometimes, once the cable is attached, you have to look up along the top of the keyboard at the F keys and see if one looks like a symbol for a monitor. If it does, you need to hold down th fn key and then press that F key to transfer the display signal.
If the external monitor shows a regular display of your laptop's screen, then you know that the problem is either the Screen Inverter, or LCD. As a laptop repair specialist, I always replace both because the inverter is right below the LCD panel behind the "frame" that goes around your LCD (screen).
If the external monitor looks exactly the same as your laptop screen with the same problem, then you know that the Video chip or card on the motherboard is about to fail and needs to be replaced. You then have the choice of replacing the entire motherboard or sending the laptop to a company that specializes in motherboard repair. Many can be found on eBay (I use them myself if the Video chip is soldered to the motherboard).
If the video chip is not soldered, it alone can be replaced. Some of them can be very expensive, all depending on your laptop model.
By going by the above diagnostic method and doing a little research, you'll be well enough informed to make the right decision for your own circumstances. I'll cast my vote that it's only the screen. :)
You are not alone with this problem. Some lines (like mine) run vertically rather than horizontally. The solution - sue HP. These screens have a known fault ie the Nvidia graphics chip is known to be the culprit. The company knows all about this issue but expect us to pay to put it right - sue them, you can do it online for around £35 (UK).
The horizontal line means that there is a loss connection in the horizontal projection of the monitor. This can be resolved by fixing the horizontal panel board that gives error. this require quite expert in the LCD troubleshooting. However, if you believe that you can do it, ok you may proceed.
please donot rate me if this not solve the problem. because i need more higher rating. just notify if you need more solution am here to assist. melnavz
I've worked on several of these thinkpads which had this problem. There are a couple of things it could be depending on what the display actually looks like. If it "whites out" , or has lines.
First, make sure the ribbon cable is connected properly. If the lcd lights up at all, the inverter is fine.
Next, while booting the machine, press in on the memory; this might work better if you only have one memory stick in the machine. Just putr pressure on the memory towards the motherboard. I know it sounds weird, but it's a possible problem.
If that doesn't do it, the lcd may be shot.
