My laptop screen is not coming on it is receiving power but still not coming on


Timothy, post the laptop manufacturer, and the laptop's model number. It's on the bottom of the laptop, Usually in a sticker, or white Service Tag.
This way I can guide you in more detail. Post back in a Comment.

A) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA connector, on the laptop.

This is an example of a VGA Cable, and VGA connector,

http://en.wikipedia.org/wiki/VGA_connector

Could be on one of the sides of the laptop, or the back of the laptop.
You can use a CRT monitor, (Looks like a small TV), or a flat LCD screen monitor, that has a VGA cable attached.

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By default the display should show on the external VGA monitor.
IF not;

There are at least three display options available:
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the same time tap once on the Display Toggle-Over key.
Which one is it? Dunno. You didn't state what laptop manufacturer, and model number.

It is one of the F1 through F12 keys. Most of the time the F4, or F5, or F7 key. Has a monitor symbol on it, and sometimes a side arrow.

No display on external monitor still?
Hold the Fn key down again, and at the same time tap once more on the Display Toggle-Over key.

If the display still does not show on the external VGA monitor, you have a bad graphics chipset on the motherboard. Usually means motherboard replacement.
(There are problems with HP Pavilion dv2000 series, Pavilion dv6000 series, and Pavilion dv9000 series, in this area. There are other model series of laptops also, not just HP. There is a solution besides motherboard replacement)

C) IF, the display shows on the external VGA monitor, you have a problem with the Video Cable, or inside the Display Assembly.

I can help you find it, just need the laptop manufacturer name, and Model Number.

Hp pavillon dv2000 line on computer


Find out if the problem is the graphics chipset, or the LCD screen.

Laptop OFF, monitor OFF, plug a VGA monitor into the VGA port on the Pavilion dv2000 series of Notebook PC.

1) The VGA port is on the back of the laptop. Looking at the back of the laptop, it is the second port from the Left.

Example of a VGA connector, (On laptop it is a Port), and a VGA cable,

http://en.wikipedia.org/wiki/VGA_connector

The VGA monitor can be a CRT, (Looks like a small TV), or a flat LCD screen monitor with a VGA cable.

The VGA monitor will now just be referred to as External Monitor.

Monitor plugged into the laptop, turn the monitor on. Wait a few minutes if it is a CRT monitor.
Turn the laptop on.

The external monitor should automatically show the graphics of the laptop.

If not press, and hold down on the Fn key, (Bottom row of Keyboard, second key from the Left. The Windows key is to the right of it ), AND at the same time tap once on the F4 key.

If graphics do Not show up on the external monitor, press, and hold down on the Fn key, and tap the F4 key once more.

[ Your laptop has at least three functions for this Hotkey. (F4)
{Also known as Display Toggle-Over key}

1) Laptop internal display Only.

2) Laptop internal display, and external display. (In this case, a monitor. A Projector can be connected here also)

3) External (VGA) monitor Only ]


A) Does the external monitor have this line going through it also?
Yes? Problem is with graphics chipset.

B) No? Problem is with screen Inverter, or LCD screen.

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

A Backlight is a CCFL.
Cold cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

A screen Inverter is a small circuit board that converts the electricity from the laptop, for the Backlight, and LCD screen.
(Too broad a statement. There are some laptops that their LCD screen, does not receive power through the Inverter. Their power is derived from the Video Cable only )

90 PERCENT of the time the fault is the Inverter

This is an example of a screen inverter, for an HP Pavilion dv2000 series of Notebook PC,

http://www.nylaptopparts.com/index.php?main_page=product_info&cPath=91_96&products_id=200

Click on the image to enlarge. (Size is approximately 1/2 inch tall, by 4 inches long)
Make a mental note of the price. This is an average price. You may also find a better price.

This is an example of a replacement LCD screen,

http://www.laptopscreen.com/English/model/HP-Compaq/PAVILION~DV2000/


A1) Without a sensitive multimeter, (Read expensive), you do not have a way to test the Inverter.
IMHO I would replace the screen Inverter, and see if this repairs the problem.

If it does not, then an LCD screen replacement is next.

B1) If the line is on the external monitor, you have a graphics chipset problem.

With most laptops a motherboard replacement is the easiest option, however it is the MOST expensive option.

It has been found that the HP Pavilion dv2000, dv6000, and dv9000 series of Notebook PC's, have a graphics chipset problem.

It isn't the graphics chipset, per se, it is the mounting of the graphics chipset to the motherboard, AND the inefficient cooling for the graphics chipset.

Primer:
Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

The graphics chipset is the GPU. Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU

Use GPU-Z to find out what exact GPU your laptop has.

I do know that it uses Intel GMA 950 for graphics, which is usually paired up with one of Intel's Core2 mobile chipsets,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Core.2FCore_2_mobile_chipsets

The graphics chipset is mounted to the motherboard with a BGA surface mount.
Ball Grid Array.

To explain a BGA surface mount, let me compare it to the Intel Pentium 4 processors, that used a Socket 478 processor socket.

The bottom of the Processor has contact pins. 478 of them.
The Socket 478 processor socket has 478 socket holes.

With a BGA surface mount, there are no contact pins, and no socket holes.

Solder Balls on the bottom of the graphics chipset, take the place of the contact pins.
Copper Pads on the motherboard take the place of the socket holes.

When installed by the factory, the graphics chipset is set into place on the motherboard, so that the Solder Balls are lined up with the Copper Pads.
The chipset is heated to a specific temperature, for a specified length, and the Solder Balls melt.

The solders the chipset to the Copper Pads. Solders it to the motherboard.
IF, the graphics chipset repeatedly overheats, the solder connections are partially melted, and this makes a bad contact. (Contacts)

A video I found that explains the above in more depth,

http://www.youtube.com/watch?v=bnkQNmKauEc&feature=pyv&ad=5823851286&kw=DV2000

Power is on but screen is blank


You can connect your laptop to and external monitor, if this works well then you need to replace your flex video cable, if your lcd turns on white your inverter it is working well, but your video needs a little help replacing flexible cord. This will fix your problem

Compaq monitor blank screen


If its a blank screen all the time that never shows anything not even a screen at startup then it sounds like the internal cable from your monitor to the motherboard of the laptop is unplugged or possibly broken. You need to remove the keyboard from the laptop to check this.

I recommend bringing the laptop to a professional if you have no experience with opening laptops.

i m in Hong Kong. The stupid HP repair center charged US 90 just for inspection!!!!! They they said the whole motherboard had to be replaced, thts additional US 630 dollars, the thing is just 1.5 yr old. They also said i don get to keep the broken mother board after replacement. This is simply irresponsible, unethical, sleazy and UNJUST!!

Thanks. right now the computer is fixed for US70. when i hv time, i'll open it up and see if i can figure it out how it was fixed. The shop suggested tht the computer wont last too long. This is such bad quality for HP... Sorry, i hv to do the following for other victims to find this easily:
