Question about Computers & Internet
The indicator lights are on, but the screen stay black except for a very faint HP logo
It may be a couple of things, inverter, backlighting, the switch that controls the display when you open and close the lid. Here is a video to help you troubleshoot the issue: http://www.youtube.com/watch?v=2Yi6GNFcP3w Have you cleaned the fan, vents, heatsink recently?

I know that you had a chat about this matter, and I hope that your issue was solved. However, I had made a note of it when I saw the chat go through. I was unable to help at that time, but remembered having seen something of this nature and wanted to follow through on it.
Although the ze2000 is not listed, other 2000 models are listed in the following link as defective - and recognized as such by HP - with this very specific defect. (Please see http://h10025.www1.hp.com/ewfrf/wc/fastFaqLiteDocument?lc=en&dlc=en&cc=us&product=18703&docname=c01087194.)
Again, if your issue has already been solved, congratulations. Otherwise, I hope that the information provided here will be of use to you, either in fixing the equipment problem yourself (perhaps with a BIOS update) or by convincing HP to do something about it. At least you would be armed with good solid documentation of their recognized issue!
If this information assists you in resolving the problem, please take a moment to rate the solution at a "FixYa" level. If you do not feel that you can rate at a "FixYa", please post back with more information regarding what has occurred subsequently and/or more details regarding the situation, and I will gladly help you until we have reached a definitive solution.

SOURCE: Hp Pavilion dv1000 Black screen
It is either the inverter board or the bulb
If it looks pink in color than it is the bulb and that can be quite the intensive project to replace
If it is the inverter board than that is not so bad and you can pick up an inverter board on eBay usually for around $10 to $20 and that usually installs right under the LCD screen (usually screwed to the LCD screen)
The inverter board is what powers the light bulb the data cable is totally separate function.
If you can see data on the screen with a flashlight but there is absolutely no light coming from the screen at all ever than it is probably just the inverter board
But there is a possibility that you could order the inverter board and have it turn out to be the bulb and if that is the case then unless you are very comfortable taking apart laptops then maybe a new screen would be best since you practically have to take apart the LCD to change the bulb.
But screen cost around 100 to 150 on eBay so if you decide to do that then might as well try for a deal like this: (I just spotted this on eBay and it is for entire new top half of laptop with glossy screen and inverter board wire harness and all for the same price or less than just the screen http://cgi.ebay.com/HP-dv1000-Pavilion-14-1-BrightView-Glossy-LCD-screen_W0QQitemZ310102538774QQihZ021QQcategoryZ31569QQssPageNameZWD1VQQrdZ1QQcmdZViewItem#ebayphotohosting
That is guaranteed to solve your problem for sure.

Try to attach your computer to an external monitor to see if it is a screen issue or a motherboard issue. If the computer does not pick up on the external right away, try to toggle it by holding down the Fn key and striking F4. If you get a picture on the external, then you have only lost the screen and the motherboard shouyld be fine.

Testimonial: "How do I do that?"
HOW TO FIX YOUR DV6000/DV9000/DV2000/tx1000/tx2000
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...
