Open cpu cabinet then you can motherboard pull cmos cell from motherboard for 10 seconds then put it back reconnect RAM memory reconnect both connection to harddrive .Make sure motherboard is not ground with cabinet. Then check. Also when you power up the computer press F8 key 5 to 6 times then if you are able to see safe mode and other menu enter in "Enable vga mode" then go to display property and change screen resolution to 1024*768 then apply. Let me know if you need further assistance. Thanks for using FixYa.

Hp Pavilion DV-4000 Screen


Are you saying the lcd screen is black? It seems like it booted up but nothing appears on the screen?

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

Screen went black


I don't know. I've never actually replaced parts in a monitor. If the bulb is expensive, it might be best to buy a new monitor. They're cheap nowadays. Or you can check if there's warranty on the monitor and it can probably be fixed for free.

Screen went dark (almost completely)


check your power cord and make sure it's plugged in all the way, and if it is, check your brightness setting.

Usually it's the Fn key + an arrow key. Make sure the brightness is up all the way
