dv9700...no backlight?

Hi everyone,

I have a dv9700 that I have owned for over a year and recently upgraded to Windows 7 (about a month ago.) I was happy with how everything was working until suddenly today when I went to turn on my laptop it appeared the screen was dead...upon looking closer I realized that the backlight was off. I could barely make out anything on the screen but it did have an error message stating that Windows failed to boot and gave the option of repairing the system. I went through this "startup repair" utility (still no working backlight) and got my computer to boot up. Everything seems to run normally now except the backlight is still not functioning most of the time (at the moment I have the screen balanced just right so that it is on.) I had a similar problem with my screen about half a year ago but the laptop was still under warranty at the time so HP replaced the screen for free...not the case this time unfortunately I seem to remember reading that flashing the BIOS can solve a problem like this, however there is apparently no support for Windows 7 through HP Support's software and drivers page (I tried installing the latest version of winflash for my laptop...vista 64 bit but got an error message saying it was not compatible with my system) Can anyone help me out with this?

Thanks!

Dan

 

I think you have a loose cable somewhere - you might have to open it up or take it to someone who can repair it

 

Loose cable, stuck lid switch, bad LCD inverter... all of which require opening up the notebook. I'd try disconnecting the lid switch cable first. Not sure where it is but it's a two pin cable. Might as well reseat the LCD cable while you're at it.
