HOW TO FIX YOUR DV6000/DV9000/DV2000
All the Problems described are Graphics Related..

Faulty Nvidia Chip..Both Intel And AMD Based Motherboards..Though More Common on the AMD..
The symptoms of the Laptop Powering on and Shutting Off Repeatedly..Or.. Powering On and Having No Video...Or... Power Strip Lights Up, Beeps,Shuts Down...Or..No Power At All...Or.. Intermittant Loss Of Wireless/Video Goes In And Out/Touchpad Slows and Freezes..
To Fix this issue, You will need to Reflow The Graphics Chip.
I will Explain In Full Detail As To The Correct Method Below....
HP DV6000/DV2000/DV9000 Compaq v2000 Video Chip Reflow Instructions
First Step Is Complete Disassembly Of All Parts And Components..
Remove RAM, Remove CPU, Of Course Remove Heatsink and Fan assembly.
Next Step is Insulating the Motherboard... You need to Protect The CPU area, The RAM area, Cover any plastic Plug ports.
Try to leave 1/4 inch area around the edge of the chip free of insulation.
To Insulate the Board.. I use thick pieces of Tin/Aluminum, you can fold up some aluminum foil (tin foil) About 4 folds thickness....
Now that you have your Motherboard Insulated... Make Sure There's Nothing Flamable Or Burnable Below the Motherboard... it will get quite hot underneath.
You will need a Heat Gun.. You can get one of these at your Local Home Improvement Store, they cost about $15 - $30.. You Will Use ONLY the LOW Heat Setting... I REPEAT..... USE ONLY THE LOW HEAT SETTING ....
Next You Will Need Some Coins.. Yes Coins..
8 Quarters and 2 Nickels... Put the 2 Nickels On the Bottom and Stack Quarters On Top...
Place The Stack Of 2 Nickels And 8 Quarters On Top Of The Graphics Chip...
The Reason for using the Coins: Using the coins serves a few purposes...
1) It Helps Transfers the heat Into The Chip More Evenly/Slowly
2) It Helps Hold The Heat Longer/Then Helps To Cool Slower
3) It Gives The Correct Amount Of Weight That Is Needed To Press The Chip

A Thing To Look Out For...
Hewlett Packard is nutorious for using the RED epoxy around the edge of the Graphics chip.. this epoxy is used to help secure the chip to the motherboard...
This is a process that is Hand Done at the Factory.. And Some Boards Will Have Only A Little Amount of this, Some Will Have Alot of it...And Some are Only Done On The Corner Edges....
If There Is Alot of This On Your Chip, You Might End Up Needing To Carefully (REAL CAREFULLY) Remove as much of this epoxy as able to....You can use a Razor Blade To Lightly Scrape This Off... DO NOT MISS AND SCRATCH THE MOTHERBOARD!!! Go SLOW...
Now Comes The Heating Of The Chip...
Start With The Heat Gun About 6 Inches Away From The Top Of The Quarter Stack..You want to be holding the gun at a 45% angle.. Aim the heat at the Edge of the chip, You Will Start Rotating Around the Chip- around the outer edge of the chip...then use tighter circles concentrating on the quarter stack, then after about 30-40 seconds, slowly move closer to the chip...
Never Move the Heat Gun Closer than the Top Of Your Coin Stack...Then Pull It Back And Slowly Repeat.. The Chip Needs To Get Hot Enough To Re-Melt The Solder Balls On The Underside Of The Graphics Chip Back Down To The Contact Pads On the Motherboard.. and this takes Quite Alot of heating to Do.... You Must Not OVERHEAT the CHip... It Is Best To Underheat it and have to Redo.. than to overheat.. It will cause the solder to break down and even crack/split.. causing failure forever...
This process will take about 3 minutes total.. Once you shut off the Heat Gun.. Leave The Stack of Coins On The Chip And Let Sit For Another 5 minutes..
Now Remove The Coins(carefull they might still be hot)
Remove All Insulation.. Reinstall RAM, CPU, Heatsink and FAN Assembly (and Of Course Thermal Pads or Paste.. Note:. If Paste Is Used.. It Must Be Silver Paste...
Now You Can Connect The Power Button Strip/ Video Cable And The DC Jack Cable.... And Plug In AC adapter .. You're Now Ready To Test For Solid Power and Video....
Upon Sucessful Chip Reflow/Rebake.... You Need To Go To The HP Website..( www.hp.com )..Click on SUPPORT AND DRIVERS, then select...DOWNLOAD DRIVERS AND SOFTWARE....Then either click the box to Auto-Detect System, Or Enter Your Make/Model Info, Once At The Page With All Of Your Drivers.... Choose The BIOS UPDATE Driver..
Choose The Newest Driver And Download/Install It... It Will Reboot The Laptop And Upon Rebooting, Your Fan Will Spin Faster And More Often Due To A Thermal Controller Update In The BIOS Update...

You neen to check your flex video cable, if the laptop turns white your inverter and backlight are working well, also your cable is connected to your MoBo, but if show no graphics maybe your flex cable are disconnected from your lcd, or need to be replaced. you need to remove your lcd back bezel to see if your flex are inserted in your lcd. This will solve your problem.

Its not the cable.
Sorry to say , you have a lemon on your hands.
Other people have been reporting similar issues.
There is a recall for other models in your line, though not yours(yet)
Recall info
Farther down on that page is a link to get an updated BIOS.
Try that. If that doesnt do it , and you are out of warranty, there is nothing to do but hope for a recall.

Hp dv6000 laptop screen blurry


Hello Al,



I hate to inform you but the graphics chip in these laptops are known for doing this. HP is aware of that. Every time some one brings me a Hp Dv6000 laptop about 75% of the problem is the system board or overheating issues.

First try cleaning the laptop screen with laptop screen cleaner

Walmart LCD Display Screen Cleaner for TVs Computers and Cameras

if its still blurry connect a external monitor to your laptop to see if the display is blurry on the external monitor (to get to toggle the video from your laptop you will have to press the Fn key + F4)

If its still blurry then its the graphics card or chip needs to be replaced. They are all integrated with the system board / mother board.

If its clear and images are good then the laptop screen will need to be replaced. hope that helps.

My acer laptop show white sceern only?


What can you do if the laptop LCD screen turned completely white? 1. Loose connection between the video cable and the LCD screen.
2. Defective LCD screen.
3. Defective motherboard (I assume the graphics card is integrated into the motherboard). Here's an example of a laptop with white screen. When you turn on the laptop, it starts but the image on the screen is completely white right from the beginning.

Most likely you still can use the laptop with an external monitor. Just connect the monitor to the VGA port on the back or side of your laptop and then switch the video output from internal to external mode.

On Toshiba laptops you can toggle between internal and external screens using Fn+F5 keys. Hold down Fn and press on F5 until you get video on the external monitor.
On IBM laptops use Fn+F7.
On HP laptops use Fn+F4.

It's possible that you have to use a different key combination on your laptop but you get the idea.

On some laptops, in order to be able to use the external monitor, you have to connect it to the laptop and then restart the laptop so the external monitor is detected by the laptop. In some cases the laptop screen may turn white because of poor connection between the video cable and the LCD screen. If you want to check this connection, you'll have to take apart the display panel because the connector is located on the back side of the LCD screen.

These laptop service manuals and disassembly instructions may be useful. Always check the video cable connection first. Reconnecting the video cable may fix your problem.

If reconnecting the video cable doesn't help, most likely you have a problem either with the LCD screen or with the motherboard. The best way to find out witch one is causing the problem is testing the laptop with another working LCD screen. you will need to connect to another monitor or your television to your computer with the vga lead monitor connection click start control panel display change display settings adjust resolution this may vary depending on your operating system you should see a no 1 and a no 2 with detect and identify keep an eye on the screen when you select the number tabs this may vary depending on your operating system when you select the no 2 tab this should be the extended desktop always click apply after making any changes or click start control panel administration tools computer management device manager scroll to monitors right click select scan for hardware changes if you can get an extended desktop your monitor is faulty if you cant get an exended desktop Hope it helps

Try plugging in an external monitor and see how the display shows on it. If the display is ok on the external then your LCD Screen is going bad. If it shows the same colors on the external monitor then your video graphics card has issues.

Keyboard lights up screen stays black....after inserting recovery disk screen still remains black...


Would like you to attach an external monitor for a diagnoses.

A VGA monitor.
Can be a CRT monitor that resembles a small TV, or a flat LCD screen monitor, that has a VGA cable attached,

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

1) Laptop OFF, monitor OFF, attach the VGA cable of the monitor to the laptop's VGA connector.

[For the HP Pavilion dv6000z Notebook PC, the VGA connector is on the Left side at the Rear. Second port from the rear. 15 pins.
3 rows of 5]

2) Turn the monitor on. If a CRT style allow it to warm up.
3) Turn the laptop on.

By default the display should show on the external VGA monitor.

If not, press, and hold down on the FN key,
(Second key from the left, on the Bottom row on the Keyboard),
and tap on the F4 key.
(Top of Keyboard towards the left)

Still no? Hold the Fn key down again, and at the same time tap on the F4 key.

There are 3 display options;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

IF, the display shows up on the external monitor, and if it is OK, the problem lies in the Display Assembly, and/or the Video Cable.

More on that in a moment.

IF, the display does Not show up on the external monitor, or if it is garbled, the graphics chipset is bad.

HOWEVER, there is a problem with the graphics chipset, for the dv6000 series of HP Pavilion Notebook PC's.
More specifically it isn't actually the graphics chipset itself, but the mounting of the graphics chipset to the motherboard.
More on this in a moment.

External VGA monitor shows a good display;
Video Cable:
The video cable is checked for apparent damage first, and at the same time, see if it's connectors are tightly plugged in.

On one end, the video cable is plugged into the motherboard.

(ALL power removed, AC adapter { Charger} and Battery, the Switch Cover is removed, and the Keyboard, far enough to lay it back out of the way. Keyboard Cable still attached to motherboard. The Display Cable is the one to the Far left, right under the left side of the LCD screen. The cable next to it, to the immediate right, is the Microphone Cable )

The video cable routed from the connection on the motherboard, up under the left Hinge Cover, and into the Display Assembly, where it then attaches to the Back of the LCD screen.

THIS connection must be checked also.

{ Just gave advice similar to this earlier. The asker's problem turned out to be a loose video cable connection, on the back of the LCD screen }

Examine the sheath of the video cable. See if there are signs of damage. If so the tiny wires inside the cable could be damaged.
Apparent damage or not, you may want to remove the video cable, and perform a continuity check with a multimeter. (Ohm's. Check each wire in the cable)

Video Cable connections prove to be tight, video cable continuity check proves video cable is OK, move on to the screen Inverter.

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

A Backlight can be a CCFL, or a series of LED lights.

The Backlight is a CCFL for an HP Pavilion dv6000z Notebook PC.
[It is 2mm Wide, and 334mm Long. Or a little thicker than 1/16th inch Wide, and a little over 13 inches Long ]

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

A screen Inverter is used to convert power (Electricity) from the laptop, FOR the Backlight, and LCD screen.

90 PERCENT OF THE TIME the fault is a bad screen Inverter.

Example of a screen Inverter for a Pavilion dv6000z Notebook PC,

http://www.nylaptopparts.com/index.php?main_page=product_info&products_id=560

The thin plastic frame that surrounds the LCD screen, and is in front of the LCD screen, (Resembles a picture frame), is the Display Bezel.
The screen Inverter is located behind the Display Bezel, and at the bottom of the LCD screen area.

External VGA monitor does NOT show a good display, it is a graphics chipset mounting issue, more to follow.

I have a HP DV4 Pavilion 1287cl laptop and the screen has gone white. When I hook it up to an external monitor it works. Any ideas? A tech friend tested the inverter and said its fine.


I've come across this a few times and almost always with an HP. It was always the video card. I can't help too much more without seeing it. My best advice would be to take it to a repair shop.
hope this helps

DV6000 No Video on LCD screen


There is a very common issue with the HP DV60xx series overheating (due to the Nvidia video chip) that causes these laptop system boards to fail. There is a listing of the "affected models" http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&product=1842189&lang=en&docname=c01300427#c01300427_dv20
And based on your product number you may have an extended warranty. As far as I understand, this extended warranty is limited to AMD processor based units which use the NVIDIA GPU (graphical processing unit) .
I would check the link I posted above, see if your Product number (usually a white sticker on the bottom near your serial number) is on the list and then call hp.
Good luck :)

Hi..

Your problem are related with my laptop problem, but i totally fix it with my own. From my experience I can tell that this problem may be related to the following:
1. Loose connection between the video cable and the LCD screen.
2. Defective LCD screen.
3. Defective motherboard (I assume the graphics card is integrated into the motherboard).
1-laptop-white-screen.jpg Here’s an example of a laptop with white screen. When you turn on the laptop, it starts but the image on the screen is completely white right from the beginning. In my case it was a Toshiba Satellite M45 laptop but this problem may occur with any other brand.

2-external-video-works.jpg
Most likely you still can use the laptop with an external monitor. Just connect the monitor to the VGA port on the back or side of your laptop and then switch the video output from internal to external mode.
On Toshiba laptops you can toggle between internal and external screens using Fn+F5 keys. Hold down Fn and press on F5 until you get video on the external monitor.

On HP laptops use Fn+F4.
It’s possible that you have to use a different key combination on your laptop but you get the idea.
On some laptops, in order to be able to use the external monitor, you have to connect it to the laptop and then restart the laptop so the external monitor is detected by the laptop.
3-video-cable.jpg I noticed that in some cases the laptop screen may turn white because of poor connection between the video cable and the LCD screen. If you want to check this connection, you’ll have to take apart the display panel because the connector is located on the back side of the LCD screen.

4-reconnect-video-cable.jpg I always check the video cable connection first. Reconnecting the video cable may fix your problem.
If reconnecting the video cable doesn’t help, most likely you have a problem either with the LCD screen or with the motherboard.
5-disconnect-lcd-screen.jpg The best way to find out witch one is causing the problem is testing the laptop with another working LCD screen. Without this test you’ll have to guess because as I mentioned before this could either bad motherboard or bad LCD screen.
You’ll have to disconnect the video cable from the LCD screen (connector 2) and the inverter board (connectors 3 and 1). After that you connect another working screen and test video.
6-test-with-another-lcd-screen.jpg For this purpose you using one of my test LCD screens. My test screen is cracked and because of that you see a wide white band in the center but it still works fine for this test.
The original screen is white but my test screen works normal (except the crack of course) and I can see the image. After this test I can tell that the problem must be related to the screen.
7-white-lcd.jpg After I'm assembled everything back together and connected the original LCD, it’s still white.
In my case this problem is related to the LCD screen and it has to be replaced.


That's my laptop brand and model, and i am searching an image regarding about my problem. This problem are common to another brand.

Hope it may helpful for you! Thanks for using fixya.

Good luck
