• 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.

• Satellite A300 - system still works, but the screen is blank

  Hello

  I was downloading an update of tempro toshiba (synco or something in that sense) for my laptop Satellite A300 and the frozen screen. I pressed the power button for 5-10 seconds until it is turned off. When I turned it the system seemed to work but the screen is completely black.

  I tried to remove the battery, and fn + F5 but the screen still won't turn on.

  Any help or advice would be appreciated.

  Rob.

  Hello

  It happened because of the updated BIOS, or during the common software update?
  In case it was an update of the BIOS I recommend contact the ASP in your country, because it seems that the ROM module must be flashed again.

  If it happened during a common software update, so I advise to remove the battery and the AC adapter and wait an hour.
  Then reconnect the two parts and check to see if you could power the laptop properly!

  Check it out!

• Satellite L40 is power on but the screen is blank

  Can someone help me with a problem?

  I'm not a computer expert and my laptop won't do anything. If I put power turns on but the screen remains blank

  Hello

  Try this:
  -Remove the battery and unplug the AC adapter from the portable computer
  -wait for about ~ 40 min and reconnect the two parts
  -then try to turn on the laptop

  If this does not work and the laptop does not start in windows OS, then you could try to insert a bootable recovery disk Toshiba and could attempt to reinstall new OS.

  If the procedure still does not have a hardware malfunction is possible, and in this case only the authorized service provider would be able to help.

  Good luck

  Hey AJ2106,

  First of all, I wish you welcome on the HP Forums!

  Like your laptop is by train (heard the noise of the fan and LED is lit), but the screen remains black, I suggest you to watch the following document 'computer won't start (Windows 7, Vista, XP)'. Now, this document you have already done the hard reset so you won't have to do it again once, but the part you want to follow the steps, is symptom: LEDs flow, the fan noise is heard, but the display is black or white.

  Please let me know the results of the troubleshooting steps.

  Looking forward to working with you!

• dv7 work, but the screen is blank

  I had my dv7-4180us for a month.

  The screen just deleted one day... the backlight of the lcd screen is turned on, and when I connect to an external monitor it show that the laptop itself works very well.

  When booting the laptop, the screen flickers when the hp logo comes on with the 'Starting Windows' screen (it flashes briefly and remains off even when you press F8 to access the BIOS screen). A cursor then comes to the screen (with the circle "busy" thing), for approximately 2 seconds, during which the display IS stable. Then that's it. You hear the sound when the logon screen is supposed to appear, and also when Windows actually loads. Occasionally, it sparkles, but the screen remains blank with the LCD backlight on. Fan comes on intermittently, as usual, all lights are functioning normally.

  Once she nomalised by itself for about 2 days, then deleted again. Windows restore did not work. The only support of HP said something had to perform a recovery, as it could be a windows problem. But it won't have the same BIOS display!

  Help!

  Hi again sent to the laptop to hp. came back, with the display now works correctly.
  On the worksheet they have ticked 'View' and 'Cable '. So, it is obviously a cable problem.

  Thank you all.

• 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.

• 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

• Equium A300D - 16 c turns on but the screen does not show anything / remains black

  Hi, I have a laptop Toshiba Equium A300D - 16 c.

  It was fine until now...

  When I press the power button, my laptop turns on but the screen remains black / off.
  The indicator disk HARD is not Flash or anything... (in case that helps)
  I also tried to remove the battery, hold the power button for 30 seconds and then reconnect the power cord... Same laptop turns on but the screen is black.

  I tried to connect my laptop to my PC using a HDMI cable screen, but without success... Laptop turned on but monitor my pc showed nothing.

  I have not changed anything inside my computer laptop or unscrewed it.

  PS:
  Quite often, I kept my laptop on the bed/pillow it may have something to do with overheating or something.

  How did I get to this point:

  Yesterday, my laptop was fine, there was nothing wrong with her... I turned off during the night, but when I tried to turn it on this morning it is where I have faced this problem.

  Any help would be appreciated.

  Thank you very much
  Rejanu.

  Long ago, I had similar problem on my old Satellite. CPU was faulty. After replacing the CPU, everything was OK again.
  I put t really know what to say.
  Maybe you should contact Toshiba and let check your laptop. They have diagnostic tools and may know what is the problem.

  What do you think?
