HP Pavilion dv1000 works fine on CRT but no LCD screen

Like it looks lke when I close the laptop, I hae to look really close to see what I'm doing. Then when I plug a CRT monitor into it, it works fine. Can someone please help me?

Sounds like the LCD backlight or inverter went bad. More probably the inverter,and that's good because,of the two, it's usually cheaper and easier to replace. Before considering those,check the lid switch to make sure that it is operating correctly and not stuck down. Ron

Hook a external monitor to the video output on the back of the laptop, if okay! there is a LCD problem with the laptop screen, causes! bad inverter board, or back light. If both show black! causes are Video Graphics Card that is part of the motherboard.
The 4 most common problems with dim lcd's on a laptop are boken screens, bad power inverter, bad florescent bulbs or a broken cable.
You can test the power inverter with a meter.
There should be 2 bulbs. If your screen is dim and your inverter is good and you can still make out what is on the screen, you probably have a bad bulb. If you can't determine which bulb is bad you'll have to replace both.
In my opinion, the easiest way to handle this is to replace the whole screen. Yes, it's more exspensive, but consider that it is most likely to fix your problem. A replacement screen comes with the power inverter, both bulbs, and the cable; already assembled and ready to install.
plug in a monitor in the side of the laptop if it shows up then the lcd
is bad. Also try and reset the memory by pulling it out and then put
it back in if not in all the wall nothing will appear on the LCD.
The lid actuator switch may not be working correctly. It's a small switch above the keyboard and led's on either the right or left side. Try pressing it 2 or 3 times to see if the display starts working correctly again. If so, it will need to be replaced.
If that doesn't work, you can also turn it on with the ac adapter plugged in. After it boots, press the power button and hold it in until it shuts off and then turn it on again and see if the display has returned to normal.
If neither of these options work, your laptop may need to have the backlight replaced.
well seems like the lcd has lost or the video card has an issue easy way to find out is to hook it up to a monitor and if the pitcure comes out fine then its your lcd screen and if it appears the same then its your video card.
