I have a HP pavilion dv 9007 laptop and the back light is not working, I am using an external monitor on it at the moment so I know everything else is ok on it.
I have read that 3 things could be wrong, the lid closing switch, the inverter board or the fluro tube.
Is there a way of checking each item, or is it replace one and see if it works, if not replace the next item, and so on until it is fixed. Also has anyone replace these items before, I have asked two computer shops if they will fix the problem and both said no, not a laptop, too many things can go wrong when replacing the back light tube or inverter board.
I have done the easy stuff before, like add HD and cd roms and more ram to desktops, but I have never played around with laptops.
I have noticed that the screen will light up when first turned on, it has a little purple tinge to it, sometimes it will flicker then go off, sometimes it goes straight off. The screen also comes on when the lid is closed and opened up again, but only stays on for a second or two, and sometimes when you change the display resolution the screen will come on but again only for a second or two.
Thanks for any help
Tony

If the display looks ok for the few seconds or less, I'd vote inverter. If you have it up longer but is pinkish, I'd go backlighting.
The manual provided seems pretty good about showing disassembly. You can buy inverters if you are not up to the task of component replacement.
I've gotten back into monitor repair after a long absence when they became cheap enough to toss. Now with tons of lcd's out of warrenty and dieing, I find myself doing this again.
I haven't had a laptop to do yet as I haven't found one new enough to be worth it.
By the way if anyone knows of any dead desktop lcd's I'd be interested

Thanks for the info, I think I will try the inverter, it looks easier to replace, and yes the screen comes on for only a few seconds.
