• The screen us black until I get to the Windows Welcome screen, where should I start to troubleshoot?

  When I turn on my computer, the screen remains black, until it gets to the windows welcome screen 7, then the computer and video works fine.

  I don't see the start of the video card or the blue HP screen information at the beginning upward.

  Problem is solved.   When I checked the computer with a new video card, I noticed that an HDMI cable was used to connect to my screen.   This allows information to move to the screen until windows load the correct driver for my video card, resulting in a blank screen.

  the phone was perfect for 1st 2 months... recently, few days back when I took my phoone out of the Holster, the screen was black but the backlight is turned on... I've done a few handfuls of battery and it seems to be ok,

  then he started to get worse, even after that the battery does no display on the screen, it was the dark night (except for the backlight).

  I started to get desperate, I reinstalled the operating system 5.0.0.32 8, it seemed to be ok for a few minutes, then back to the drawing board. I reinstalled the same version of the OS for a couple of times, but the screen did not show what either. not even the OS loading screen (the first one). I tried downgrading etc... no use...

  the phone shows no signs of improvement.

  Since my phone has not left any warranty, I don't know what to do.

  I agree.. is not sound like a problem of software for me, but rather the LCD needs to be replaced.

• HP Pavilion dv5 (KS878) screen becomes black. Flickers. Sometimes works with AC adapter / CC.

  Dear HP users,

  I've had my HP Pavilion dv5z-1000 for four years now.  My parents bought this computer during the sale of the labor day in 2008.  After almost a year of daily use, I encountered my first problem.  One night during my first year of high school the screen burned completely. In my head I was scared and called HP the next day.  Thank God I was under warranty and they replaced or repaired the LCD screen for me.

  Nearly a year later, when no unsecured computer does the same thing again.  This time I couldn't see the computer zap or FRY in front of me.  I turned it on one day and to my surprise, the screen was black.  I took out the battery, turned on the computer with the charger, and the screen started to work again.  Unfortunetely, these two hours of happy he was working while on the load screen went black again.  I called HP and they said I would have to pay because I wasn't not under warranty anymore.

  My father has bought a new computer dell laptop after that and I used it since.  I'm now going to College, and I desperately want to FIX this HP computer and use it as a backup.

  While on the current the sceen can work for a certain period of time.  Sometimes, the screen can last for 2 + hours or only barely 1 minute, in which there are flickers constantly and then boom - the screen goes black again.

  I tried these solutions and I tried to connect the computer to an external monitor (my LG TV) via an RGB - PC cable and the result is connectionless.  I heard that there are countless problems with screens HP including, in particular, the model I bought.  If anyone has any suggestions on what is causing this problem please let me know.  I still don't know if this is my video card, motherboard, the LCD screen, or if the wire connections are damaged/loose.

  I use my droid 2 LED flashlight to see the screen sometimes.  My office is always in the background when it turns black.

  Help a future student.  It's always a great laptop except the * beep * screen is the only problem.

  I agree with you that it is the power inverter and that is why I asked you to use the flashlight. Electric inverters cost less than $20 and a computer store should help you to replace at least for an hour work. Some stores charge $40 - $150 / hr would be fork and I think that in my area, most is about $50-$ 80.  I think that the forums of HP (I think we have to show you the answer?) would be a good reason to buy another HP!

• MacBook Pro 2015 turns on but the screen remains black...

  Hello

  Today, I tried to turn on my MacBook Pro, but my screen stays black. When I press the caps lock button, it turns green which I guess means he lit. I've also heard the startup chime it generally makes when you turn on. I already tried to turn it on and off several times and reset the SMC and the LANDAU... The screen is always black.

  Could someone help me please?

  Also a few minutes ago the fan has started to make noise in the macbook...

  But the screen remains black.

  Thank you

  Shaynidw

  Hi shaynidw,

  From your description, it seems that your MacBook Pro is powered, as soon as you hear the startup chime and see the light on the keyboard.  Thus, it seems that the problem may be with your screen or the video card.

  On the screens you see when you start your Mac

  Power on

  

  When you turn on your Mac, display is off (black) and you hear a startup chime. Your Mac Initializes his BootROM and memory (RAM live). It then performs a power - on that self test (POST) and a test of BootROM. If you hear beeps or chimes at this stage, this indicates a possible hardware problem and start stops. If you add memory to your Mac, check that it is installed correctly.

  White screen

  

  After that only walking self-test is completed, your Mac sends a video signal to your connected screens. The screen may appear black or grey at this point in the boot sequence and backlight of the screen should light up. If you do not see the image appears on your screen after a few moments, try increasing the brightness of your screen. If you use an external monitor, make sure it is properly connected and turned on.

  shaynidw, if set up the brightness of your screen does not help, you have an external display (computer screen or TV) that you can attach to your MacBook Pro to test?

  In addition, you can try to start your computer in safe mode to see if you get different results.

  Try safe mode if your Mac does not end commissioning

  If the problem persists, you may need to take your computer to an Apple Store or service provider authorized Apple , so they can inspect the video card and cables to isolate the problem.

  Take care.

• On the Satellite A210-14 t LCD screen turns black randomly

  For several days, I have the problem, my lcd screen turns black all of a sudden, the 'photo' is just disappearing. but the backlight is still and the system is still running (which happens most of the time in battery mode)
  When I close the laptop, pc goes into stand-by mode and so I open the pc again and the screen works again
  But this isn't really a solution.
  What can I do? Fresh grafix drivers are installed.

  BTW:
  I use WinXP

  HM, how long do you want the machine. Maybe you should check the powersaver for battery operation parameters when the display is sharp because it can be a characteristic powersaver the screen turns off.

  If please check your powersaver settings and set the time when the screen turns off at maximum or turn it off, then check if the error appears again.

  Would appreciate the your part feedaback. :)

• 520 TouchSmart all-in-One begins, but the screen is black.

  Hi all

  I had a Touchsmart 520 for 2.5 years (warranty expired it y a.5 year) and enjoy a lot of the computer.

  One day the screen flicked once, and since then, he's black.

  The computer is still active. I can turn it on and can be accessed via the network.

  The problem is that the screen.

  I ordered a new screen from ebay, but of no use. I got a new MB, but always the same question.

  I even tried to take graphics cards out there (as I thought Valentine's) and I tried to use the support of the onboard graphics, but still no use.

  So, new screen + Mo + LED backlite, the computer is running, but the screen is black.

  One to the rescue?

  Thank you

  Roye

  Hello again Roee,

  Thank you for the updated information and I can actually respond directly to the question of how it is connected. You're right it's the LG 6pin cable that provides power to the converter card, while the backlight is also connected to the converter card. I am providing you with a link to the list of HP parts store the parts of your computer where you can see the part number 654251-001 - rear panel light FFC (LG 6pin) 250 mm. You will also see the part number 653864-001-23 converter card which you may need to replace.

  You can also buy the parts there, too, if you wish.

  I was unable to locate the manuals or documents that would give you clear instructions on how to properly install the BACKLIGHT, but you can follow the basic steps in reinstalling the converter card that I have set out below:

  Step 1. Gently detach the connectors of power and backlight of the Board of Directors
  Note that the location of the connector backlight will vary according to the manufacturer of Panel
  Step 2. Remove both screws of the card and pull the jury on the PC
  Step 4. Align the two holes on the plate with the spacers inside the unit
  Step 5. Replace the two screws of the Commission of the converter
  Step 6. Replace the connectors of power and backlight to the Board of Directors
  Step 7. Set the DIP switch on the Board to match the configuration for panels manufacturers

  The configuration of the DIP switch for each manufacturer of Panel is painted stencil on the converter card itself

  Please re-post if you need extra support. Thank you again for post you on the HP Forums. Have a wonderful day!

• IPAD look black screen - like black but no curtain

  Hello

  I have an IPAD 16 GB Wifi Silver Air and I have the following problem.

  Recently (maybe to do with the upgrade to 9.3.1 but I can't be sure) after playing with the IPAD for about 20-30 minutes the screen goes black while I hear that the ipad still works (IE play a video). The touchscreen is sensitive, but nothing appears. I can get it back if I press the button sleep on and outside and asks me to slide to unlock. First, this happens so the frequency of the black screen is more faster, every 5 minutes and then every 2 minutes. If I let it cool then I can work for 20-30 minutes and I have the same behavior again.

  I tried the hard reset with the buttons,

  I tried factory defaults restore with iTunes as a new ipad

  I tried enabling black curtain with three fingers and disable it

  I disabled / enabled siri

  I tried to tap on the back as suggested by some users. I turned to auto-lock forever. But always the same behavior.

  Can you please help. Does anyone else have this behavior? How can I go down to see I

  Best regards

  Take your device at the Apple Store. This may be the problem of equipment.

• Toshiba Qosmio DX730 PAQ13A - no signal - the screen remains black

  When I turn on PC (all in a single DX730 PAQ13A-010005) the amber light turns white as it should. However, the screen remains black.
  If I unplug the connection, and then reconnect it, a message appears on the screen indicating 'PC', it then changes briefly to display the message no Signal.

  He will not go to log in screen etc. because the screen stays black.

  All advice appreciated.

  Must be the hardware problem.

  It seems that no signal can be picked up by the monitor...
  Probably the mother or any other element connected to the motherboard is defective...

  I guess its time to contact a technician if you want to solve this...

• Screen turns black and shuts off when wakes up Portege Z830 - 11M

  Hi all

  Anyone know what could be the reason for the screen goes black and turns off when the laptop wakes up?
  The laptop is Toshiba Portege Z830 - 11 M W7HP, purchased in September.

  The problem started shortly after I bought the laptop, but gradually began with a period of 1-2 seconds black screen whenever I tried to wake the portable computer of fashion 'sleep'. He didn't look like a regular part "blackout" of the wake-up process so I just tried to ignore it, but it started to happen more often recently. It got really worse after two months of use and the black screen two or three times until I'm at the login screen. The error was also difficult to re-create because it was random. Sometimes, the screen went black once sometimes twice or just blinked for a fraction of a second.

  Yesterday, I worked during the day and at night it turned really bad. The screen went black several times, whenever I went back to work after a short break.
  I changed the laptop off when I'm done, but when I turned back on it in the morning, the screen was just black. I tried to use the touchpad, but it is only the screen on the gray.

  Can anyone suggest what to do?

  So finally that cannot start the laptop is Hmm normal?
  It would be interesting to know if this help:
  -Battery adapter and ac removal
  -Press and hold power button do this for 30 sec
  -Then reconnect both sides.
  Turn on the laptop?

  If this is not good enough, you're in trouble I guess its hardware related issue and in this case you must service help
