Having problems with your HP Pavilion DV5234US Notebook Laptop ?

The LCD screen on my Hewlett Packard Pavilion has gone scratchy. In areas that should be white there are horizontal cyan lines. To the right of words and other things there are places that are white and cyan horizontal lines that are always moving. It is very scratchy and distracting and has ruined the resolution on the screen. Can someone tell me what it is and if it is fixable?

Hi..

Your problem are related with my laptop problem, but i\015\012totally fix it with my own. From my experience I can tell that this\015\012problem may be related to the\015\012following:
\015\0121. Loose connection between the video cable and the LCD screen.
\015\0122. Defective LCD screen.
\015\0123. Defective motherboard (I assume the graphics card is integrated into the motherboard).
\015\0121-laptop-white-screen.jpg\015\012Here’s an example of a laptop with white screen. When you turn on\015\012the laptop, it starts but the image on the screen is completely white\015\012right from the beginning. In my case it was a Toshiba Satellite M45\015\012laptop but this problem may occur with any other brand.

Most likely you still can use the laptop with an external monitor.\015\012Just connect the monitor to the VGA port on the back or side of your\015\012laptop and then switch the video output from internal to external mode.
\015\012On Toshiba laptops you can toggle between internal and external screens\015\012using Fn+F5 keys. Hold down Fn and press on F5 until you get video on\015\012the external monitor.
\015\012On IBM laptops use Fn+F7.
\015\012On HP laptops use Fn+F4.
\015\012It’s possible that you have to use a different key combination on your laptop but you get the idea.
\015\012On some laptops, in order to be able to use the external monitor, you\015\012have to connect it to the laptop and then restart the laptop so the\015\012external monitor is detected by the laptop.
\015\0123-video-cable.jpg\015\012I noticed that in some cases the laptop screen may turn white\015\012because of poor connection between the video cable and the LCD screen.\015\012If you want to check this connection, you’ll have to take apart the\015\012display panel because the connector is located on the back side of the\015\012LCD screen.
\015\012
\015\0124-reconnect-video-cable.jpg\015\012I always check the video cable connection first. Reconnecting the video cable may fix your problem.
\015\012If reconnecting the video cable doesn’t help, most likely you have a\015\012problem either with the LCD screen or with the motherboard.
\015\0125-disconnect-lcd-screen.jpg\015\012The best way to find out witch one is causing the problem is testing\015\012the laptop with another working LCD screen. Without this test you’ll\015\012have to guess because as I mentioned before this could either bad\015\012motherboard or bad LCD screen.
\015\012You’ll have to disconnect the video cable from the LCD screen\015\012(connector 2) and the inverter board (connectors 3 and 1). After that\015\012you connect another working screen and test video.
\015\0126-test-with-another-lcd-screen.jpg\015\012For this purpose you using one of my test LCD screens. My test\015\012screen is cracked and because of that you see a wide white band in the\015\012center but it still works fine for this test.
\015\012The original screen is white but my test screen works normal (except\015\012the crack of course) and I can see the image. After this test I can\015\012tell that the problem must be related to the screen.
\015\0127-white-lcd.jpg\015\012After I'm assembled everything back together and connected the original LCD, it’s still white.
\015\012In my case this problem is related to the LCD screen and it has to be replaced.


That's\015\012my laptop brand and model, and i am searching an image regarding about\015\012my problem. This problem are common to another brand.

Hope it may helpful for you! Thanks for using fixya.

Good luck
