You might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

My hp dv5000 screen is blank


Problem can be;

A) Graphics chipset
B) Video Cable
C) screen Inverter
D) LCD screen

Let's diagnose, and find out.

A) Graphics chipset:

To start off with, the Pavilion dv5000 series of Notebook PC's; is NOT known to have a problem with the graphics chipset.
The Pavilion dv2000 series, Pavilion dv6000 series, and Pavilion dv9000 series; does.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port; on the laptop.
The VGA port is on the Left side of the laptop, and located towards the rear.

This is a general example of a VGA connector (port), and VGA Cable,

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

Scroll down a little for VGA Cable example.

You can use a CRT type of monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.
IF not:

There are at least 3 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 F4 key.
The F4 key is the Display Toggle-Over key.

Still no? Hold the Fn key down again, and tap once more on the F4 key.

No display on external VGA monitor, suggests a problem with the graphics chipset.
(Most of the time it is a problem with the Mounting, of graphics chipset TO motherboard. If this proves to be your problem, state in a Comment )

Display on external VGA monitor means the problem is the Video Cable, or inside the Display Assembly.
(screen Inverter or LCD screen)

B) Video Cable:

The Video Cable plugs into the motherboard, in an area under the Switch Cover.

(Left side.
Switch Cover is the plastic cover above the Keyboard, and below the LCD screen. Has the Power On Button, LED indicator lights, etc in it)

It then loops by the left Hinge, and goes up into the Display Assembly.
There is a small separate wire that comes from the main Video Cable, and connects to one side of the screen Inverter.
The main part of the Video Cable goes on, to connect to the back of the LCD screen.

Example of Video Cable,

http://www.batterycentury.com/hp-430531-001-cable-p-215726.html

Click on image to enlarge.
The wide connector you see at the top/left, connects to the back of the LCD screen.

The wide connector at the bottom/right, connects to the motherboard.
The single cable (Wire) coming off at the bottom, connects to one side of the screen Inverter.

Just due to normal repeated opening, and closing of the laptop; the Video Cable may become pinched.
This leads to it being pulled on, and may also lead to damage of the Video Cable.
(Stretched/Broken wires)

Procedure is to Physically check the connections of the Video Cable. Visual inspection alone will NOT do. You need to physically see if you can plug the connection in tighter.

1) ALL power removed. Remove the AC adapter (Charger), and Battery.
2) Remove the Switch Cover.

[Switch Cover is just that. A Cover. I will give a link to a free Service Manual from HP Support, towards the bottom of this solution ]

Try to plug the Video Cable connection at motherboard, in tighter.
Once done reinstall the Battery, and attach AC adapter. Plug AC adapter into power.
Turn the laptop on.

Still no? Turn laptop off. (Hold down on Power On button)
Remove ALL power again.

This time check the Video Cable connections at screen Inverter, and back of LCD screen.

The plastic frame in front of the LCD screen is the Display Bezel.
Example,

http://www.ebay.com/itm/447997-001-HP-Pavilion-LCD-Display-Bezel-DV9000-Series-w-Webcam-GENUINE-/170992584210?pt=US_Laptop_Screens_LCD_Panels&hash=item27cff3c612

Service Manual indicates to remove Display Assembly from laptop, in order to remove Display Bezel.
IMHO this = NO.
I think you can remove the Display Bezel, without having to remove the entire Display Assembly.

This video details removing the Display Assembly.
Shows replacing the LCD screen.

http://www.youtube.com/watch?v=NNyvf4KqeIY

What my concern is with removing the Display Bezel, is the integral Hinge Covers that are a part of it.

I believe the Display Assembly can be tilted far enough back, that the Display Bezel can be removed, and carefully ease the Hinge Covers out/off at the same time.

Why not just remove the Display Assembly?
A whole lot less stuff to reconnect, after you have checked the LCD screen connection of the Video Cable, and screen Inverter connection.

After disconnecting the LCD screen from the Hinge Brackets, you just tilt the LCD screen forward, and check the Video Cable connection.
Then slightly tilt the Display Cover back, so the LCD screen can rest against it, and reinstall power.

Connections are plugged in tighter, and this proves to Not be the problem, go on.
(Don't forget to remove ALL power again)

The Screw Covers are made of synthetic rubber, or plastic.
They are held in place by a type of rubber cement.
I like to use a computer pick, (Much safer than a blade!), and lift up at the base of the Screw Cover.

I also like to GENTLY stick them to the Display Bezel for safekeeping. (They like to stick to the tool, your fingers, and it seems passing cars. "Oops, dropped one. Where'd it go? Hmmmm)

If you are careful with them you can reuse them. (Doesn't stick anymore? Apply a TINY dab of rubber cement to them, with a toothpick)

Screws removed, I suggest cut a piece of thick construction paper, that just fits the inside edges of the Display Bezel.
Helps prevent scratching the LCD screen, from your fingernails, when you go to flex the Display Bezel, and remove it

The LCD screen is an Assembly of layers. They are held in the factory aligned position, by the metal Screen Frame which surrounds them.

There are screws that hold the Hinge Brackets TO the Screen Frame, and there are screws which when removed, will take the Screen Frame apart.

ONLY remove the necessary screws which hold the Hinge Brackets, TO the Screen Frame!

I am having problems with my screen on my hp dv5000 notebook. The bottom have of the screen will freeze and only the top part is scrolling down and moving. After a while my screen will start to get lines...


Hello,

the fault could be from your laptops graphic card.

Connect your laptop to an external monitor, and if the screen still freezes on the external monitor, then the fault is truly from your graphic card.

But if the external monitor displays well, then it means the problem is from your screen inverter.

From which ever angle the fault may be coming from, you need to take the laptop to a repairer to fix the problem for you. I don't think either of the fault is what you can handle.

Take care.

No light from my replaced display


If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
