• 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

  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.

  It of hard to say what's going wrong here, but maybe it s just a small issue that could be solved easily.
  Try this;
  Remove the battery, disconnect the adapter.
  A few hours and reconnect the two parts.
  I had this problem in the past and leave the laptop disconnected during the night.
  The next day, I connected battery and adapter A\c and the laptop worked again

• When I start my Satellite A300 the screen remains black

  When I turn on my Satellite A300, the screen remains black and doesn't change at all... Any help please?

  What is password problem in your other thread? Already solved or what?
  If the problem persists, I don't see any sense to start this thread because people don't understand what the problem is.

  Please do not mix two questions and explain exactly what you see on the screen after turning on your laptop.

  Press and hold the power button for more than 15 seconds.
  Plug the DC power adapter (leave the battery for now)
  Press the power button

• 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.

• HP2000 369wm: connected replacement screen, the screen remains black.

  Hi I'm new here, I tried to find the solution here, but I can't find what I'm looking for but anyway...

  My laptop had a broken screen so I used an external monitor via the vga input. One day I was messing around on the web and I got a virus that paralyzed the system that all frozen cuz then I thought that if I plugged in my phone that I could try to fix it, but eventually transmitting it to my phone, but luckily I could reset it. I thought that if I replaced my screen that I would be able to get the screen for boot sequence or something but the screen remains black and externally will not work. There is something lacking in me to use the primary monitor, I just put? Or is there a way I can format without being able to see? I'm sure that the virus all messed up my boot sequence, but without seeing the screen and unable to use external, I am at a loss.

  is there another number or anything I should post?

  Here is your model and it doesn't have a Vista operating system... it's a Windows 7 or Windows 8 double, so check again?

• Re: TV TOSHIBA 26EL800A - TV is on, but the screen remains empty

  Hi all

  I have a Toshiba TV 26EL800A purchased in May of this year. Tried to turn on the TV using the remote control mode standby (red light) to on (green light) that has the remote control - the screen remains empty (as there is no power) and after a few seconds the light changes again red - standby again.

  Tried this using the keys on the TV as well and the same thing (have checked batteries for remote control, checked PowerPoint (my dvd player works the same record 2 and it works) but don't know what else is causing the screen lights?)

  Any suggestions?

  I put t really know if you can find the solution here on the computer systems forum.
  What you can try is to unplug TV, leave for a while and check again.

  If the same thing will happen again and again I recommend to contact your local dealer and ask for help or contact the provider of Toshiba directly.

• 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.

  It's your graphics card, I think that this particular model has 128 MB of ram, which. You need at least 512 MB to start the game, so don't expect anything good or flashy.

  Upgrade your video card!

• Satellite A300D is runnig but the screen remains black

  Hello!

  I have a big problem with my Satellite A300D.

  This morning I forgot to connect my laptop to the net elec, and so my battery drains.
  When I reconnected and restarted my laptop I could see the Toshiba and splash screens of Windows, but after these the laptop screen becomes black.

  You can see the cursor, but the rest disappeared.
  The screen is all black.

  Strangely, when I press ctrl + alt + delete, the vista opens again, and I can select and view the Task Manager.

  What should I do!

  Hello

  There is a solution that could help bring back the screen.
  in Notepad, remove the battery and unplug the AC adapter.
  Wait about 30 minutes and reconnect the two parts.
  Then try again to put the laptop.

  In many cases, this procedure helped to set something like this.

  Good luck

• HP Pavilion dv7-1240us: preheating indicator light, a fan noise is heard, but the screen remains black, laptop will not start.

  Perform a hard reset

  I added an external monitor and restart the computer. All seeing power are on, fan and hard make sounds and still nothing on both screens.

  Reinstall all hardware

  Still nothing but black on both screens.

  Is it possible that a virus could cause black screen and does not start.  Seems the laptop crashes, because all the lights remain.

  Please notify.

  Hi there @SVJ69

  Welcome to the Forums of HP Support! It's a good place to find the help you need, so many other users, the HP experts and other members of the support staff.

  I understand that you get a white screen when you turn on your system. I'm happy to help you with this. I would recommend that you start with searching through this page. Since the construction in and external display do not respond, I would start with the displays.

  This can help more evenly. If another hand, you get error messages, or a repetitive pattern of flashing LED, let me know.
