Hp pavilion has black screen problem [Solved/Closed]

My black screen problem disappeared when I began to open the screen to a wider angle before pushing the power button. If the angle of the screen to the keyboard is less than 90 degrees it appears to trigger the problem. By opening to wider than 90 degrees, the problem goes away. Once the screen is activated it doesn't matter what angle the screen is put at. The wide angle is only necessary at boot up. This leads me to believe that it is a hardware issue. This may be an easier and less violent solution to the problem than pick the thing up by the screen. Hope this helps someone.

hi, to all who have that black screen.
dont listen to all those who tell you to buy a new lcd...
there is a way to fix it.

remove battery, remove plug and hit the power button for 30 seconds.
then put back the battery and start your computer
once you see something on the screen , plug the cord.

it works for me all the time.



the black screen always comes on when my battery dies..... i've done this a million times!

i had this problem BEFORE. the way i will tell you will work %90 first of all if you can remove the ram memory DO IT SO if you cant try without removing FIRST.

-remove battery pack(if you can romove memory ram aswell) and wait 10 mins
-now start charging laptop without battery pack for 2 mins
-unplUg the power AND press and hold the power button for 45 seconds
-REPLUG THE POWER CABLE BUT DONT PUT THE BATTERY PACK YET

NOW OPEN THE LID WIDER YOU CAN PRESS POWER BUTTON YOU WILL SEE YOUR SYSTEM WILL START ONCE YOUR SYSTEM BE READY SHUT IT DOWN PUT THE BATTERY PACK BACK AND CONTUNUE TO USE YOUR LAPTOP

Here is my checklist to determine why you have a black screen.

+++++++++++ WHAT IS NOT YOUR PROBLEM ++++++++++++++
1) Firstly,,, your video card is fine, as if it was damaged the picture would be black on external monitor too.
2) The drivers are fine for same reason listed above. (Although you should still see if update available)

+++++++++++ CHCKLIST TO DETERMINE YOUR PROBLEM ++++++++++
1) Open case and to make sure power and data cables for screen have not come loose.
2) If cables are intact than you have either a problem with your screen, backlight, or inverter.
3) To Test,,,
a) Remove laptop screen and try it in another laptop...
b) If lcd screen works in other laptop than your inverter is shot.

+++++++++++ SOLUTIONS +++++++++++++++++++++++++++++++++
1) If screen works in another laptop, check YOUR cables in other laptop to see if they are faulty, if cables are fine than the inverter is shot and replacing LCD screen will NOT fix the problem, but waste your money.
2) If its determined LCD screen is dead, buy a new one. (Most laptop screens are interchangable)
a) Do not feel compelled to pay more for a brand-specific LCD, Just make sure you get compatible LCD.
b) Get correct size (14.4, 15, 15.4, etc. and resolution (VGA, SVGA,XGA)

3) If; using above criteria you realize it is your inverter board that has failed follow these steps.
NOTE FOR NEWBIES: (Inverter is little computer boatd, about 2-3 cm. x 10-20 cm located above
keyboard and just below monitor with at least 1, mabye 2 plugs connected to LCD)

4) Inverters are generally much more system-specific than LCD screens.
a) To replace inverter, note all possible information. Remove inverter (simple 2 screws and remove cables
Check for part number, etc on top and bottom. Note all info and laptop's exact model #.
b) Google,,, starting with inverter part number to find your replacement part.
C) Otherwise try googling laptop replacement parts sites and use either inverter # or laptop model#.

Now you know how to fix a black screen problem for any laptop made in the last ten years!

GOOD LUCK, ALL THE BEST,
Ste-

I had the same problem with an HP Pavillion Laptop (N5290). Computer would start to boot and the screen would go black. I tried everything humanly possible and stumbled onto the solution to resolve it.
1. Plug the AC Adapter into the Notebook PC.
2. Press and hold the Power button for 5 Seconds to turn off the PC.
3. Press and hold the F10 key while you press the Power button to turn on the PC. Release the F10 key after text is displayed on the screen of the PC.

The text on my screen read "error 44 Stuck Keyboard Key."

I could not visibly see any key that was stuck in the down position but I started punching each and every key on the keyboard. Suddenly, the screen came alive - the system booted up - went straight to Windows XP.

Hope this helps someone out there.

ATTENTION ALL HP PAVILION NOTEBOOK USERS WITH A BLACK SCREEN PROBLEM !

I have the answer, the problem is that your screen cable has been damaged due to constant opening and closing of the lid. This cable connects just above the keyboard under the speaker casing and runs by the side of the screen hinge up to the back of the screen and connects at the top.

Basically, the cable runs between the base of the laptop and the back of the screen and there are about thirty tiny wires wrapped up with tape. When I took my laptop to bits I removed this cable and re attached x4 broken wires using additional super fine wire ply and tape. The ideal would be to solder the new wire. My tip is to burn away the wire casing using a match/ cigarette lighter very briefly then rub off the plastic to expose the wire using finger and thumb.

If you don't have the skill level to repair broken wires then simply buy a new screen cable, when you open the laptop up there is a code under sticker on the cable. You can buy them from any good HP spare parts retailer for upwards of £15.00.


To remove the damaged cable, to the following.

1. Remove the battery and power cable.
2. Remove all the rubber pads from the inside of the screen to expose screws (x5) (dont unscrew at this stage)
3. Tip the laptop over and remove x6 (I think) sliver screws from within the battery compartment. (These screws hold on the speaker cover above the keyboard that also houses the quickplay buttons volume and power button)
4. Very carefully using a flat blade screwdriver prise off the speaker cover around the left and right hand side of notebook. DO NOT PULL COMPLETELY OFF THIS COVER UNTIL YOU UNPLUG THE ATTACHED QUICKPLAY WIRE !!!
5. Once this speaker cover is completely removed then you will see x2 hinge covers that are kept in place with a screw on each. Remove each of the screws then gently prise off the hinge covers being very careful not to disturb the wires that run around them.
6. Next is to remove the inner screen cover surround. All the screws should already be exposed, remove them all now and them very carefully prise the casing off using a flat blade screwdriver.
7. At this point you will now see additional screws attaching the lcd screen to its mounting plate X3 at each bottom corner and x2 at the top. Remove all of these screws and this will allow access to the back of the lcd screen.
8. You now need to remove the cable which should be in plain view front and back. Firstly disconnect from above the keyboard using a screwdriver to gently prise off the clip. Next remove the plug from the inverter (a long strip of circuit board that runs at the bottom on the screen. Only disconnect the left hand end that connects to the screen cable. Once these two have been released, go around the back of the screen (helps to gently move the screen hinge forward for this bit. Remove the celloptape that holds the bottom of the cable in place, then remove the plug at the top of the screen by firsly removing the holding tape. Be very gently and pull out using both hands gently wriggly out the socket.


At this point the cable should be free and can be gently removed from the note book for either repair or replacement. Repair is quite simple if you are handy with electronics but beware, the cables inside the black tape wrap are very very small. It is delicate work. If you can't fix then replace by quoting the code number on the cable sticker.

Refitting is the opposite of the removal, just remember to be very careful with the cable placement and when starting to open and close the lid again, do it very slowly the first time to ensure no part of the cable is trapped.


THE JOB IS DONE !!!! HAPPY DAYS.

I had the same problem with my pavilion dv 9000 and I coudn't fix the problem.
The only thing that I can say is not to buy HP notebook.
See below if your notebook series and product number are on the list and repair it for free.

Try Pressing CRT/LCD (F11) on your computer. that may work!

I reported the to the Better Bus Bureau - I've had a black screen for over a year - HP refuses to fix although they recognize the problem in several of their other laptops (if you have one on the list they'll fix yours http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=uk&docname=c01087194) not the DV9500 though? This is my first and last HP ever!

Report them please if you've had no luck with customer service - it's not fair they get away with selling comps with the same known problem over and over and not resolve when people call it in.

The Better Business Bureu says use the San Jose office btw. I called to make sure as they're are several diff addresses for HP listed in the BBB.

Good luck all!

hi,
all u have to do is take the battery out and bout ten seconds later put it bak in. Then start the computer and it will work cause i had the same problem.Try it!

Hello all,

I have the same problem. I am suing HP pavilion dv5t which i bought on october 2008. I can connect to the external monitor though. So the problem should be with the monitor.

I talked to the customer service through chat and they were ready to provide me free mail service to send the laptop for repair. Since i am currently residing outside USA, i could not use that service and instead contacted the only available authorized service provider in my current location (Nepal). The said they will replace my monitor but it will take a month for that as they have to file the complain to Singapore and upon investigation on my product and warranty, they will send the new monitor.

Have to wait for a month to get my laptop repaired and its not even sure that it will be repaired in a month.

its the screen problem put it on tv it will work good

hi,
it may be that the switch which turns on the screen is stuck or even broken.
if so, contact your reseller, from where you bought the pc.

I fixed my problem simply by removing and re-inserting the battery.

HP DV9000 Warning! Banned from HP's site!

Bad motherboard, overheating problem, no support from HP


I have been banned from HP's web site for posting this. Therefore, I am going to post on every web site I can. My son bought an HP DV9235, which is a lot of money for him as he is 23 years old. I called for support and they gave me the standard BS "$400 for repair". This "repair" would not permanently fix the problem as overheating is one of the main causes of the problem.

So... I called the BBB, the FTC and the Ca Dept of Consumer Affairs. The CDCA was the only agency that replied. I spoke with a nice lady (details below) that said she would pursue my complaint with HP's legal department. I encouraged her to go public with the information she has to help others rather than just to pursue my complaint.

Here is the information that got me banned:

Good luck dealing with HP!

hi, I have an hp pavilion dv6000 and recently i have had similar problems. Most times when i turn it on the botton half of the screen is blank or fuzzy..thus making it unreadable. I actually pick up the computer by pulling on each side of the screen...just jiggling it and it always corrects the problem for me. It makes me think the problem is with the connection between the laptop and the screen.

Works for me...interested if it would work for anyone else...seems like this is a common problem.

hi all
i v the same issue here in DV6000- i agreed thats the best thing STOP BUYING THE DAMN HP..
i did read alot solutions in mise. sits- but didnt works with me..
may it help ypu guys.
1-press F8 after turn on th laptop.
2-remove HDD and battery ans pressing turn in for while (10Sec.) then connect ur laptop
with power cable.. then turn on they said screen will start workin..

I've had the same problem too with my laptop. I have the same kind and I just learned how to solve this. Since you can connect your laptop to your tv, its easier. You have to go to start and in the search box type in system restore. It may take a minute but it will show up. Once it comes up, it will show you the date that you can restore it back to. You may not want to do that date so go to where it says choose a different restore point and click next. It will then display all the other dates that you can restore your laptop to. Choose one but maybe not the most recent one. You will have to close all other windows you have open before you start it. The system restore will then well, restore your laptop and restart it when it's done. You should see the windows logo come up when it comes back on and you will be able to type in your password. Your screen should show.
