Presario V2000 screen goes white

First thing you want to try is getting the laptop to display on an external monitor. If it doesn't replicate the same issues then you know it is either the screen or the inverter/backlight.

if it does then it is most likely a motherboard issue and sadly can not be fixed outside of replacing the board.

when turning on the system go into the BIOS and reset back the seeting s to factory defaults and reboot the system .. If this fails then reseat the Hard drive may have come loose or ?

did you recently add new software ? drivers ? hardware?

It is located on the trim at the top of the display screen.

no its not a driver you have a video chip getting ready to fail.on the v2000 it intergrated in to the mother board. soon you will be joining many other compaq v2000 and m2000 owners in the search for a mother board compaq has updated part numbers it a whole differant board for these units due to having a common failure rate of the original mother boards.Compaq know there was a over heating of the video chip that leads to failure but has not offered any assistance to there customers. john@johnslaptops.com

hi ashok, it's a major problem with the Compaq laptops...
as they donot provide display & audio drivers with the system!
you should search the drivers on google search using ur Model no. !

for the display you can check by connecting the laptop to the monitor through the vga port

This does sound like the cable, but it could also be the inverter. Here's a step by step to removing the screen.

sounds like a loose ribbon cable from the MB to the screen.
Here is a manual that should help you take it apart.
