Question about Compaq Presario 700 470024-192 Notebook
I have a compaq laptop, just recently when I turned on my laptop only white screen appears. What's wrong with this?
1. That can be connection related problem. I check connection between the video cable and the LCD screen, try reconnecting the video cable. It’s necessary to take apart the display panel, unplug the video cable from the connector on the back side of the LCD screen and then plug it back in. In some cases reseating this connection helps. 2. If reconnecting the video cable doesn’t help, here’s what I do in this case. While the display panel is still disassembled, I turn on the laptop and wait until image appears on the screen. Then I move the video cable a little bit without touching the LCD screen. If moving/touching the video cable affects image on the screen, it’s possible that there is a problem with the cable. Apparently there’s a short somewhere inside the cable. In this case, replacing the video cable may fix the problem.
3. If reconnection the cable doesn’t help and moving/touching the cable doesn’t change image at all and the only way to get better picture is moving/touching the LCD screen itself, apparently there is a problem with the LCD and it has to be replaced.
