• Alienware x 51 starts, but the screen remains black.

  I bought my x 51 all with warranty 1 year ago a year and a half, recently it has been giving me some problems and today I can't use it yet at all.

  The problem started with my screen remains black when I turned on my computer (punt, never awake from sleep), but which would be corrected by me once or twice by restarting the computer. That did not last too long, and soon it did not matter how many times I rebooted the computer. I finally had to unplug the computer and press and hold the power for 30 seconds to see if it worked.

  He did, but this solution has worked only once, and now I have nothing seems to regularize my situation. I tried switching monitors and cables with my brother (who is an identical 51 x), but nothing has worked.

  To summarize:

  My computer turns on.

  Not funny lights or noises (save a beep on startup)

  Screen remains black on reboot of the screen it says he receives no signal and falls asleep.

  No problem when it runs normally (not funny colors, stripes on the screen or blur).

  Help, please. Dell support wants 70 to 110 dollars to listen to even my problem, which is money, that I don't have at the moment.

  Thanks for anything that might help!

  Sounds like you have a dead video card, from the link above looks like there is no output from vga Intel to tun tests, you must remove the old video card and test with another video card that works to verify that the card is in fact dead, like your brothers x 51 remove the video card and test it on your machine.

  If I had this machine in front of me I would use one of these babies for once then run tests on the video card.

• 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.

• Dell computer laptop starts but the screen does not light

  Hello

  I have a laptop Dell older (studio 1558) and when I used it the other day, 'static' filled monitor image and then the screen went completely black.  Now when I turn it on, it seems that the computer starts well but the screen is black.

  Get yourself an external monitor, easy solution, right? -bad.  Unfortunately when I plugged my laptop in a separate monitor, the monitor (which works fine) showed no images.

  Still, I had this laptop for a few years.  I see about being 'easy' opening and closing of the laptop.  This has been the case in recent years, however, so I don't know if something has finally given...

  I'm not the best computer savvy so sorry if I was not more detailed... any ideas, what is wrong and how do I fix?  I rather would not somewhere that make me fixed.

  You will probably get a better response if you re - post it in the forum of the laptop and mention the version of Windows, too. (This is the forum office.)

• Acer blue 720 and the fan are on but the screen remains black

  Hello

  I appreciate any help that can be provided.  I tried to remove the batter on my daughter 720 and reinsert, but this problem persists.  I can hear the fan and the blue light turns on but the screen remains black.  I tried to rest for 30 seconds and esc, refresh and power.

  Thank you

  Well, when the scrween does not at all (even in text mode which allows a recovery) then it is most often a problem with the cable bwteeen the motherboard and screen, most often following it is a failure of the screen (which requires generally a matter of co-location as cracked screen) and from time to time, it is the motherboard. Probably time to contact Acer support to see on a repair.

• 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

  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!

• Satellite X 200 - 15 K power on but the screen is black

  Hello

  I have Toshiba Satellite X 200-15 K, two days ago, I have problem with screen, the screen I have noise, I think it's the same error in my display driver and I have stop near windows xp and try to after 1 min, but the screen has more noise when the startup boot image and I stop by button / stop on laptop.

  Then do what I ve tried again to turn on my laptop but on the screen, I see only artifacts (same squadrons of colors) and after that, my laptop can not work, I tried to power on him but I only power led and HDD light works only 5 sec and after off the coast, and the cooler works 5 sec too and after offshore.

  I tried to remove the battery and the RAM and the wireless and all that I can :), but nothing happens, but when I try to power without RAM I see on power light beep two red and two yellow (IE my motherboard work).

  Maybe it can help me. I think I have dead motherboard.
  And for me, it is interesting that someone may have similar problems.

  Thank you.

  P.S Sorry for my English :)

  Hello

  Let's summary.
  You had a few artifacts on the screen, and now, you are not able to start the unit.
  Nothing appears on the screen; Neither the Toshiba start screen appears is good?

  Hmm seems material issue I m thinking about GPU (graphics chip).
  What do you think of this?

  If it's really a problem of graphics card, then you will need to replace the motherboard.
  In most cases the chip belongs to the mobo anyway... something like this can be done by an ASP in your country.

  Then please get in touch with the guys to get more details about this

  I wish you good luck

• G7-1070us Pavilion: laptop starts but the screen is intermittent

  laptop starts up ok and the display is available on the external monitor or a hdmi to the tv. turn top display backlight lights up but the screen is blank.

  Hello:
  
  Yes, it was what I thought. I do not understand how the same pilot worked as a temporary solution.
  
  Decide for yourself after you have identified the cause of the problem. If it's just a matter of cable, I think it's worth repair. Otherwise, I have no idea, maybe it'd cost you big.
  
  Give it to get it repaired in a good local computer shop.
