If you put the old inverter back on and the system works, I'd suspect the inverter is bad. If the system is still a no post after putting on the old inverter, then you may have a motherboard problem now.

My hp laptop screen is blank on start up


Hi,

Due to the problems in the inverter or due to the troubles in the cable connection usually screen flickering happens in the display of HP Laptop. As the inverters are responsible to supply power to the back-lit of the screen, any problem in the inverter would create troubles. By replacing your inverter and by checking the connections of the cable in your HP laptop, this problem could be easily resolved.

My hp dv600 when powered up looks normal but if i give it a few seconds the screen goes black and wont come back i shined a light and i do have picture but no light maybe ballast?


alejandro,

An LCD screen cannot produce enough 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.
Very similar to the Fluorescent lamps, (Bulbs), used in homes and businesses, but on a MUCH smaller scale.

HP Pavilion dv6000z series Notebook PC, is a general series designation. The EXACT model number is on the bottom of the laptop in a white Service Tag.

The HP Pavilion dv6000z series of Notebook PC's used either an LED or CCFL type of Backlighting.
Depends on which model it is.

http://www.screentekinc.com/backlight-ccfl-led-explained.shtml

As stated in the above information a Backlight is mounted in the back, or on the side of the LCD screen.
The LCD screen is composed of layers. These layers are held together by a metal frame which emulates a picture frame. If the Backlight is a side unit it will be held in place next to the layers, and inside the metal frame.

[Which means the LCD screen's metal frame, (LCD Panel Frame), needs to be opened on one side.
This will leave the layers which compose the LCD screen loose. The layers MUST be held in the proper placing when changing out the Backlight. Not an easy job to accomplish]

An Inverter is used to change the power coming from the laptop, to be used by the LCD screen, and Backlight.
90 percent of the time the problem is the Inverter.

The Inverter for the Pavilion dv6000z series of Notebook PC's is located inside the Display Assembly.

The Display Assembly is the
1) Display Enclosure Cover, (Plastic top of laptop),
2) LCD screen,
3) LCD Panel Frame, (Metal frame around LCD screen),
4) Display Bezel, (Thin plastic frame which surrounds the LCD screen in the front)
5) Camera Module
6) Inverter
7) Display Enclosure Cover Hinges (2)
8) Display Enclosure Cover Hinge Covers (2)
9) Wireless Antenna Transceivers and Antenna Cables
10) Microphone receivers and cables
11) Various mounting screws

[The Top Cover for a Pavilion dv6000z series Notebook PC is essentially the Palm Rest. The cover under the Keyboard]

With the Display Bezel removed the Inverter is located at the bottom.
(Display Assembly removed from laptop first)

My HP DV5 1159se was working fine last night and then this morning I go to turn it on as usual and a blank white screen comes up. The start tones are the same and I could even type my password in to log on...


If the inverter board or the back light behind the screen were bad your display would be blank, "but windows would be visible barely" the white screen indicates a bad LCD and must be changed. It is also possible the video cable from the motherboard to the screen has come loose and will need to be reseated back into place to fix it.

Hi, my hp dv2000 screen is blank when I turn it on. It hums and lights up like it's supposed to, but the screen is completely blank! What do I do?


Look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the back-light stays off even when you open the LCD screen or turn on the laptop. The switch turns off the back-light when you close the LCD display to save the laptop battery power.

If that didn't fix it then there are 3 things that could have gone wrong:

1. Video cable connection from inverter to LCD got loose. To check this, follow instructions from step 3 on how to open the LCD and check if cable is fitted properly.

2. The video inverter is faulty
The screen inverter failure is very similar to the back-light lamp failure. In both cases the screen gets very dark and the image on the screen becomes very faint, barely visible under a bright light. If it's still under warranty, take it for a replacement. You can replace this otherwise - you can find the inverter under the screen, follow the procedure described at point 3 to open up the screen.

3. The LCD monitor is faulty
If it works on an external monitor most likely the LCD is faulty and needs replacement. If it's still under warranty, take it for a replacement. If not, you can do it yourself, it's pretty easy. Remove the rubber covers on the side of the screen, unscrew the screws take the plastic cover off, disconnect the video inverter and put in the new LCD after you connect the video inverter to it.

My screen light has stopped working.


More than likely the inverter board is shot. Start by replacing this and if it does the same thing then the CFL lights went out. Here's a couple of links that might help:

I have a dv 1000 HP & there is no screen but it continues to work with a seperate screen attached


Hi:
If your laptop works on a seperate screen, but not the laptop screen, you have either a bad LCD, or bad LCD inverter board. The inverter boards are less than $20, and mounted inside the lid, at the bottom of the display. LCD panels are about $100.

No display on hp laptop


Well, believe it or not. It's good news that it still works with the external monitor. That means it is not the video card which is embedded in the motherboard and is very expensive to fix. Here is a link to disassemble instructions for your motherboard. Scroll down till you see the dv9000's that should be your laptop. Good luck
