I have a hp laptop. was on line and screen went black. and will not show again. it strats up sounds but black screen.what do i do


1) Do you have a VGA monitor that you can use for an external monitor?
{VGA monitor is also referred to as a CRT monitor. Looks like a small TV}

The back of the laptop, or side, has a VGA port. The VGA monitor is plugged into it.
{Laptop off}
Then the VGA monitor is turned on, and allowed to 'come to life'.

Now turn on the laptop. Press the Fn key down on the keyboard, and hold it down.
Now press the Monitor toggle over key.
Since you did not state the HP laptop Model Name, and Model Number, I can only give you generic guidance on this.

The monitor toggle over key has a monitor screen symbol on it. It will be one of the F keys.

(It's an External Monitor toggle key.
Press it one time and the display toggles over to an external monitor.
Press it again, and both the laptop LCD screen, and the external monitor have a display on them.
Press it once more, and the display goes back to the laptop's LCD screen )

If display shows up on the external monitor, you have a problem with the display of the laptop.

Primer:
An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is used as an additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp {Bulb}
Similar to the fluorescent lighting used in homes and businesses, but on a MUCH smaller scale.

{Average Backlight is 3 to 5 inches long, and half the diameter of a No.2 pencil.
The Backlight is located on one edge of the LCD screen}

An Inverter is used to provide power for the LCD screen, and the Backlight.

90 percent of the time the problem is the Inverter.

Inverters are relatively cheap, and if I knew the Model Name, and Model Number of your HP laptop, I could give you a link to HP Support where you could download the Service Manual for free.

This way you would have a manual to show, and detail how to replace the Inverter, and I could guide you.

I could also give links for your perusal for Inverters.

There is one more thing however.

HP Pavilion DV2000, DV6000, and DV9000 series laptops, have a graphics chip overheating problem.
The laptop comes on, the blue indicator LED lights light up, but the LCD screen is black.

This video explains why, shows a solution to fixing the problem, and details out a lot more than I am privileged to state here,

I have an HP laptop and the screen went totally black but the computer seems to be running otherwise


let your pc rest first for 5-10 mins. then when you open it press both "delete and F8" rapidly. this will then take you to the Bios screen then save changes and exit.

Laptop pavilion 8310 no dispaly, getting beeps on start up


Remove laptop battery, and unplug AC power adapter for ten minutes, if this does not work there is either an hardware fault, or a system problem.

If the computer try to load Windows, then you get an error message,then you usually fix the problem reinstalling windows.

If the computer beeps and you get nothing on the screen, then it is usually an hardware fault.

My screen randomly went black, nothing. I restarted the laptop and still nothing. I can use it attached to my TV, but nothing from the screen.


If you were typing while it happend it is a possibility that you did a keybaord shortcut that turned off you laptops screen. a FN keystroke. Look on your keyboard for the FN (function key) and another key that has what looks like a monitor. Or a square with a smaller square in it. Then his the FN, the press that other key.

My laptop went funny the picture statred to distort now iv restarted it i can see anything the laptop is on but the screen is black with lines on it


2 horizontal or vertical lines on ur screen or 2 lines in a cross are problems that can be quite easily repaired by a specialist.. in fact if th lines are very distinct a repair shop may b able to follow them directly to a broken connection thats causing a loss of info on th screen along th edge of th lcd.. often these connectors can b repaired rather than having to buy a new 1.. def not a biggie, but def needs sorting by experts.!! x.x.x Dyanne x.x.x

Hi i have hp dv6000 my laptop is on but the screen is blank some time they came up and then went out again please help.


Turn the computer ON. Take a flashlight and shine it at an angle into the screen. If you still see the image on the screen most likely the inverter in the screen has went out. I would suggest taking the laptop to the local authorized repair station.
