    The laptop had a thermos fall on it the screen, but it was never dropped or jarred.


    I purchased the LCD new from ScreenAid.com - the unit I received looked to be in good repair - but the sellers have a less than stellar reputation - as I later found with some searching.


    When I first installed it (Sunday) it worked fine, but I noticed a few lines near the bottom of the screen (yesterday). It then expanded to take up the bottom third of the screen and it flickers quite a bit the - lines shift in some places and are constant in others.


    I'm going to plug into a ext. monitor to test the GPU theory.


    Thanks,


    Shawn

    I've completed the external monitor test, which was fine. Sounds more and more like the LCD is at fault.

Hello and thank you for using Fixya's services.

The LCD screen you purchased; was it brand new or used?

If it was new, then it has to be a cable and not the inverter. I would recommend checking everything, even inside the screen itself to make sure all connections are set in place. A good trick alo is to gently squeeze the top right and/or left hand corner of the screens and see if the lines go away. If so, this indicates the connections on top are loose.

If it was purchased used, then it could be the inverter but not usually as the inverter makes the screen darker when going out.

Why was the screen replaced?

If the laptop was dropped or fell, then it could simply be the video graphics card. It may be loose or damaged. You can test this by connecting an external monitor to the laptop and see if it flashes or has the lines.

Please let me know and I will further assist.

    Glad I could help! By the way, you can check eBay for a new LCD as this is where I purchase all of my screens for customers. Looking at under $50.00. Check the feedback of the seller before purchasing, Most are used but you may be able to find a new one.

Thin white horizontal line in the center of the screen when the tv is on.


Hi Tim,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a component failure.
Take it to a repair shop.

White screen on hp w2007 LCD monitor.


Troubleshoot an HP LCD Monitor
HP makes a number of liquid crystal display, or LCD, monitors.
LCD monitors create an image by passing light through a liquid crystal solution that either blocks the light or allows it to pass through to a color filter.
LCD monitors are ideal for use with a computer as they present an excellent still image and cannot suffer pixel burn-in like other flat-screen display technologies.
Even quality monitors run into the occasional problem and need some basic troubleshooting before sending them in for service.
Check the power cord to make sure that it is plugged in securely to both the monitor and the outlet. If you are using a surge protector, remove it and plug the power cord directly into an outlet that you know is working.
Detach and reattach both ends of the cable running from your computer to your monitor.
If your HP LCD monitor has more than one connector, use the other one to make sure that the connector isn't the issue.
Remove any switch or extension cable that may be present between the computer and the monitor.


Restart your computer. A fresh start will correct many software issues.


Check the documentation of your video card to make sure that it supports HDCP, or High Bandwidth Digital Content Protection, since the screen may be blank when you are trying to watch high-definition content through a video card that doesn't support it.
Some older HP LCD monitors also do not support HDCP, so check your monitor documentation as well.


Go to your video card manufacturer's website and install the latest drivers for your video card. Instructions for installing the drivers will vary by manufacturer, but they should be listed with the driver software.


Change your resolution to a preset video mode to make sure that you aren't trying to operate the monitor in an unsupported resolution.
Different models of HP LCD monitors support different preset video modes.
All of the preset video modes for your monitor are listed in your monitor's manual.
Resolutions of 1024 x 768 and lower are supported by almost all HP LCD monitors.


Press the "Auto/Select" button on the front of the HP LCD monitor to correct any images that are dark or blurry.
If this does not correct the image, press the "Menu" button on the front of the monitor to bring up the on-screen display menu, where you can use the "+" and "-" buttons to scroll through the options and "Enter" to select the option that you want to change.
Adjust the brightness and contrast as needed by selecting them and using the "+" and "-" keys. Press the "Menu" button to exit the menu.


Press the "Menu" button to enter the menu, scroll to "Image Control" and press "Enter."
From here you can choose the "Auto-Adjustment" option and the HP LCD monitor will automatically adjust the horizontal and vertical positioning to center the screen.
The ability to adjust these settings is available only if you are using VGA inputs.


Contact your retailer or manufacturer for any additional troubleshooting steps for your particular model of HP LCD monitor.
If your monitor still has issues, you may need to send it in to be serviced.

Fix a White Screen on an LCD Monitor
When an LCD screen has turned completely white, there are three normal causes: the screen is defective, the video cable is not connected correctly, or the graphics card on the motherboard of the computer is faulty.

You will need to troubleshoot these possibilities to determine which problem you have.
If you are not experienced in working on computer equipment, you should not attempt to disassemble your LCD screen because you could easily damage it.
Seek professional assistance unless you have experience working on computer hardware.

Disconnect the white LCD screen from the computer by unscrewing the blue monitor cable. Connect the working LCD screen to your computer by attaching its blue monitor cable to the same slot.
If your computer display does not show on the functioning LCD screen, try rebooting your computer.
If it still does not display, the problem is with your computer's graphic card on the motherboard. Seek professional repair assistance.
If your computer display shows normally on the working LCD screen, proceed to Step 2.
Unplug the LCD monitor with the white screen.
Disassemble the rear panel of the monitor with the small screwdriver.
Carefully separate the screws into piles so that you can keep track of how to reassemble the monitor.

Locate the internal video cable, a gray cable with a plug on the end that connects to the main components of the screen.
See the References section for photos of the video cable for assistance.
http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/
Unplug the cable, checking for any debris or blockage.
Reconnect the cable firmly.
Reassemble the LCD screen. Plug it in and connect it to your computer.
If the screen is still white, you have a defective LCD screen.
You will need to replace it or take it to a professional repair service for assistance.




Without this test you'll have to guess because as I mentioned before this could either bad motherboard or bad LCD screen.
You'll have to disconnect the video cable from the LCD screen (connector 2) and the inverter board (connectors 3 and 1).
After that you connect another working screen and test video.
For this purpose I'm using one of my test LCD screens.
My test screen is cracked and because of that you see a wide white band in the center but it still works fine for this test.
The original screen is white but my test screen works normal (except the crack of course) and I can see the image.

After this test I can tell that the problem must be related to the screen.
After I assembled everything back together and connected the original LCD, it's still white.
CONCLUSION. In my case this problem is related to the LCD screen and it has to be replaced.

Horizontal blinking lines appear on the screen of Sony Vaio VPCEL 10EL


Possible cause:

1. Video card failure.
2. Bad connection between video cable and LCD screen.
3. Bad LCD screen.
4. Faulty video cable.


Possible troubleshooting steps and repair solution:

1. First of all, test the laptop video output on the external monitor. If you see same flashing lines running through the image on the external monitor, you have a problem with the video card. If flashing lines appear only on the laptop screen, the failure is not related to the video card.

2. Just in case, try re-seating the video cable connectors on the motherboard/video card and maybe the back of the LCD screen. It' s not likely but possible that connection is loose and reconnecting the cable will fix the flashing lines.

3. If re-seating the cable connectors doesn't help, most likely you have a faulty LCD screen. The LCD screen has to be replaced.

4. If replacing the screen doesn't help, try replacing the video cable. It's very unlikely that this problem is related to the video cable but there is a slight possibility of that.

You could have a faulty video cable or connector or a faulty LCD screen.
Try reseating the video cable/connector at the motherboard. If that doesn't work then a replacement LCD screen may be your option.
LCD screen replacements are available on the Internet, do a Goggle searh for replacements. You can try LCD Parts. - use this link to get to their WEB site for service, repairs, parts & DIY info.

The white screen tells me that the display cable (inside your monitor) may be unattached or broken.
The color bands if they are vertical or horizontal lines tell me that your display cable needs to be replaced.

So overall replace your display cable. If this doesn't entirely fix the problem your logic board (inside the monitor) needs to be replaced.
