View 9 Replies View RelatedI was using my HP Pavilion g7 the other day, while gaming and the screen went black for no appairent reason. i haven't down loaded anything recently and i run virus software.
We went to the HP support web site and went through several diagnotics. When the laptop is rebooted the screen on the laptop will flash images of my desk top but once the machine boots up the screen remains blank. you can see the glow from around the edges but that is it. I have another monitor plugged in currently and the system is functioning propertly except for this. We have also done the following, hard reset,Test for memory modual problems, test the hard drive. I was also trying to update the video drivers but the system tells me the drivers are working properly.
I have had my Hp dv7 notebook for a few months now and have had no problems. But all of a sudden, I turn on the computer and see nothng but a blank, black screen. I do not know if I changed the display settings or what, but I cannot see anything. I know the computer is functioning because the fan turns on and the keyboard lights work. When I connected my laptop to an external monitor, I was able to see that my computer was on and fully functional. In fact, I am using it right now on an external monitor to type this message.

It's about my old notebook, hp pavilion dv7 1130el bought 5 years ago, it always wokerd fine but now its screen goes black without reasons... at first I thought it might be overheating, but that's totally random:
-sometimes works even when is hot
-sometimes goes blackafter I turn it on and then open google
-sometimes works for a while, when its not hot, and then goes black
I don't have a second monitor to connect it, but even if the screen goes black I can still hear the music from youtube, so I guess it's just the screen.
HP Pavilion dv7 1130el, Windows 7 ultimate, runned fine for a year with this OS.
I discovered that my display wasn't turning on yesterday when I tried turning on my notebook. Luckily I was able to plug it into an external monitor with a VGA cable and I have a monitor in my office, but I really cannot be restricted to my living room or office to use my laptop.

To the problem now : A few days ago my laptops screen started out of a sudden shutting down/turning black( no lights at all ). This was happening while using the laptop at random. The screen had no lights, and if i use a flashlight on it there is nothing. like its turned off completely.
Before this happens. This behavior varies. Sometimes it flickers from my desktop to a black screen then back on and some times not. Most of the times screen changed to a random color (green mostly) then becomes black/shuts down.
NOTE: The laptop keeps running, i can hear the videos playing so it probably isn't a gpu chip or gpu issue , music and games.
Here are everything i tried and all or the details i could accumulate in past couple of days:
1. If the screen flickers , blacks out and then turns back on i get a message that gpu drivers have stopped working and recovered ( on both amd and intel ).
2. If the screen blacks out, on rare ocasions if you close the laptop lid and let the laptop go to sleep , when waking up screen works again ( noticable due to screen moving)
3. I tried installing 4 different drivers all with clear install. ( didn't work)
4. I tried to to recover system with restore point. ( didn't work)
5. I tried to lower the screen brightness. ( didn't work)
6. tried this trick: Turn off laptop.. Remove battery.. Hold the power button for 30-45 seconds.. Plug-in the charger ( don't put the battery in )Turn on laptop and see if it works.
Very Noticable details:
7. Since on of the rare fixes requires to move the lid i tried shaking the screen a bit or pushing it slightly to different directions. This actually does the trick and turns the screen back on ( i am right now typing this after using this "trick"
So, with this one as a hint there are a couple of stuff i have in mind but i am not sure ...
a) There is a loose LCD cable and when i type a little vibration moves it and ends up in a black screen.
b) I read that if you use a flashlight and you cant see your desktop it means its a bad inverter.
c) Can the inverter have a lose cabe instead of the lcd ?
Currently the screen looks ok ( maybe its the certain angle it has after i moved it. Tried to play a game for a few mins and i got the black screen again. Closed the lid so the laptop goes in sleep mode then opened it and it worked. Just for the records.
Just tried to play a game again. got the blackscreen, shaked the screen a bit and it worked but for the 1st time i get the message " Application has been blocked from accessing graphics hardware" , Can it be that its the GPU after all or maybe drivers?
Tried to play a game again and it seem to trigger the issue . ( i am currently running the laptop with only the intel drivers installed) ...

dell inspiron 1525 Laptop and I've been having this problem for 2 days now .. when I try to shut it down ..
only the screen turns black but the HD and everything is still on !! and I have to press the shut down button to shut it down !!
HP pavilion 14 with touchscreen on windows 8 every time i press the shutdown button screen go off but the power button keep lighting and the fan too i waited around 5 hour nothing happen. I reformatted and i got the same result updated to 8.1 and I tried the latest driver on the hp site same result i thought it was a hardware problem so i tried installing win 7 it worked perfect.
Note that i had a lot of problem installing ati driver for windows 8.1 from the HP site it do not recognize the graphic card so i installed the ati moblity driver 14.4 . and i got the latest bios update.
i have a problem with my 2 year old vaio sz. Since some weeks, screen turns black in irrregular intervals. The system is still available, but i can't see anything on the screen. The only solution is to push the power button an switch to standby mode. Afer pushing the power button again, the system comes up again and the screen turns on! The problem only occured in battery mode.
I tried nearly everything to fix the problem. I reinstalled Windows XP, tried different power management settings... nothing worked.
I have repaired a few laptop in my time so when a friend said his screen was black but he could read it with a flashlight I guessed right away it was an inverter problem.
I got a new inverter off of *bay, carefully removed the display bezel, swapped in the new inverter and powered it up. Successfully boots into Windows ! Shut it down, screwed the inverter down, put the bezel back on and now the display comes on for 1 second, just long enough to see that "Acer" splash screen, and then goes black. Yes you can still read the screen with a flashlight.
Checked the power in and out wires, they look good. Re-seated both connectors. unscrewed the inverter board from the display so that it is :floating". Nothing. Swapped in the old inverter and it acts the same ?
When I turn on my Acer Aspire 4750, the screen just turns black, and I can't do anything but to Force it turn OFF?

View 2 Replies View RelatedI bought this Envy 17 3D in December of 2010 from HP Websight. The Model is WY771AV and runs Windows 7 with 1080P and Uses A M D 5875 Graphics. The Last 30 days, @ boot-up, the screen will turn solid white when I try to start it up. All I can do is hold power button down to power off and retry. 9 0 % of time, retry fails(does same thing), but occasionally I can go to startup repair , run system restore and use machine for 2 or 3 times before the next white-out.
View 2 Replies View RelatedCurrently whenever I startup my laptop the display flickers. If windows fully boots or I try to enter one of the startup menus the will flash briefly on the screen and then the display will return to and remain black.
I am able to run an HDMI cable to my TV and it seems to be running fine other than going black with the occasional distorted picture of windows booting.
For the past few months I've had issues with my display on my laptop. At times I would start the computer and it would either go to a black screen and take a very long time to load or I had to restart it to get it to go to the start screen.
