I understand that your notebook is only displaying a black screen, and I would be happy to assist you in this matter!
Since you have already performed a hard reset and replaced the LCD, I recommend following this document on Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot. This should help your computer regain a successful display.

HP Pavilion Dv7 4180ea Black Screen

Hi,
I have a HP Pavilion Dv7 4180ea and my problem is that last night I put my computer on sleep and today, when I turned it on, there was nothing but a black screen, even if the computer was working fine in the background.
I connected it to my TV through a HDMI cable and the laptop is just fine, everything works perfectly when connected to the TV, but when not, the bloody screen won't turn on.
I searched what the problem would be, but I couldn't find anything relevant to my situation.
I tried a hard reset and then I took the whole laptop apart, cleaned it out, changed the thermal paste and everything, connected the display cable...and made sure it was properly plugged in and turned it back on, but no luck with the display, it is still black, even though the computer itself works.
Any help would be greatly appreciated.

Hello Flav,
I see that you're having issue with a blank display. I will try to help you with this.
As you've tested with another output source and it's working, this generally imply something wrong with the actual display.
Though you've taken it apart and put it back together may not have resolved, it it wasn't just a loose wire.
Anything software related, may not be viable to try, but you can still attempt a few things:
The remaining steps in here: Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot
This may have additional steps -Resolving Problems with Notebook Displays
Also, make sure that the graphics driver is up to date. There were also recent Windows updates effecting computers in various ways included black screens. If this happened recently (after updates), try a System Restore
If none of the above works, I'd advise contacting phone support for repair/replacement options.

Hp pavilion dv 7 black screen

Hi, I have a dv 7 pavilion c670Ca, I had trouble with the motherboard when I tried to clean the fan(black screen and caps lock blink continuesiouly, no fan sound), I did replace it with a new you one but I still have the black screen with orange wifi light on, the fan is turning too and I have the light on on the behind of the screen. I tried to disconnect everything but nothing does work !
Any suggestions ?
Thank you

Hi @Taqui3 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv7 Notebook and issues with the LCD screen not showing on the display after fan replacement. if you can see the image on a monitor it is not the graphics card and could be the LCD screen or the cable.
Have you connected the Notebook to a monitor? Here is a document on how to connect to a monitor if you need it.
You could restore the BIOS with this document selecting the reloading the BIOS default settings which could resolve the issue with the fans.
Here is a link to computer won't start for Windows 7.
You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook.
When performing a System restore please note remove any and all USB devices. Disconnect all non-essential devices as they can cause issues.
I hope something here helps you.
Thanks.

Pavilion Dv5-1009el - Black screen and blink caps lock and block scorr

Hi,
I just replaced the motherboard of my pavilion that reported an error as object. The purchased motherboard is new and hp original.
After having changed, I turn on the pc and work fine, i see the hp logo and enter to bios, after I turned off the pc without starting windows.
I inserted the battery and powered on the pc and returns to the old error, the LED of caps lock and block Lock blinks...
So I tried to update the bios from USB using winkey + B. The computer emits two beeps but does not read from any USB port and the LEDs go out for a while and then blink again.
What can I do?
Greetings,
Enzo.

Hi @shmurray,
Welcome to the HP Support Forums!
I understand you are getting a blink pattern on the Caps lock LED, when you turn on the notebook. I am happy to help you with this.
I am including the page on the error codes for your reference: Blank Screen LED Error Codes
From that document the pattern you are getting indicates a memory problem. You said that you have tested the memory. What exactly did you try?
The document suggests reseating the RAM or trying a new set of RAM and then restarting the notebook. If you are still getting a memory problem after trying both of those things, ie a 3 blink code again, then it would likely suggest that there is a problem with the motherboard itself, either with the memory slot or one of the controllers related to memory.
In that case I would suggest contacting the technical phone support number at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.
http://www8.hp.com/us/en/contact-hp/ww-phone-assist.html
If however reseating the memory or replacing it leads to a different error code or message please let me know, Although in that case the following may be helpful if you still have a blank screen.

Pavilion dv6-1230us Black Screen after installing Windows 7...Please Help

Hi,
I recently installed Windows 7 and everything was working fine until my computer went into hibernation. Before this, I installed all the drivers and software from the HP website for my computer for Windows 32 bit setup. After my computer went into hibernation, my computer will not start up in normal mode; rather, it starts in safe mode only. When its starts in normal mode, the screen just turns black and nothing happens. The login screen comes up perfectly fine but after I login at startup, the screen just turns black. Please help, I don't know what else to do whether it is a driver or software issue from the software from the HP site.
Thanks,
Daniel

Hp pavilion dv6 laptop black screen

Hi all please is any one help me I have my hp pavilion dv6 laptop.
The laptop is working,have the necessary sounds after i
turn it on,but the problem is that the screen stays always black
..I connect the laptop to external monitor and it shows that everything is working properly. But It not working on laptop screen what should I do heplllllll

Hi
I'll try helping you with this,
You'll have to give it for repair - display assembly replacement. The display panel might be at fault here as your system works good when connected to external monitor.
But before that,
Do a hard reset first --
Turn off the computer by pressing SHIFT KEY while you click SHUT DOWN.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer, shut down system.
Remove the battery from the battery compartment.
Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory.
Insert the battery and plug the AC adapter back into the notebook computer, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
Next:
To confirm, connect it to other monitor & do a full extensive hard drive & memory test from BIOS, tap quickly F2 or F10 soon after powering on the system.
If all tests are passed, contact HP service center.

Pavilion dv6-3040sa, black screen, flashing caps lock

Hey all, In need of some help for a friend, her laptop has had this issue for a while now and only just come to me for help. Her HP Pavilion DV6-3040SA has an odd issue with it, if you power it up the display doesn't come on and the caps lock just flashes, it will continue to flash until the laptop is turned off. On the help section a flashing caps lock does not refer to any particular error. I've reseated RAM, tried hard resetting, reseated the CPU and it managed to power up, then after it was turned off, it wouldn't power up again and had the same issue, after playing with it some more it powered up and worked for 2 days, when it promptly stopped working again. Any reason for this issue?

Processor failures can be have inconsistently. I have seen processor failures start with 1-2 second hangs in the OS to working one day and not at all the next.
The blinking code you have desribed is a beep code of one. Review the following table found here.
Caps Lock/Num Lock
1
CPU
CPU not functional
Reseat replace CPU.

2
BIOS
BIOS corruption failure
Restore BIOS from onboard backup (jumpers)

3
Memory
Memory module error not functional
Reseat memory modules (see next section).
Test memory from UEFI or BIOS.
Replace bad memory modules.

The options for a blink code of 1 is to reseat the CPU as you have already done or to replace the processor. Since the issue returns after reseating the CPU, it looks like the CPU needs to be replaced. Sorry.

Pavilion dv6-7010us black screen, caps lock blinking indefinitely and orange wifi light

The laptop is a HP Pavilion dv6-7010us resently installed windows 8.1 pro, 8gb ddr3 (4gbx2), 320gb hdd (not the original hdd)

Problems with Windows 8.1 Updates - Black Screen after login

Dear All,
I have a HP Pavilion g6 (SKU is D0Y12EA#ABU) and it's been running Windows 8.1 64bit without any trouble ... until recently.
On the last two occasions that I've done a Windows Update, something has caused the laptop to stop booting correctly. I get the logon screen but once I input the password, it gives me a black screen and a mouse cursor. I'm able to boot into Safe Mode and I've tried updating the Intel Graphics drivers but it doesn't help. The only recourse I end up having is to roll back to a Restore Point and prevent Windows Update from running.
Does anyone know if there is a specific update that is causing this? If so, can I get the KB number so that I can stop it from installing?
Regards,
Gareth

For Intel GraphicsOnly
I have a DV7-7133nr to which I have modified to SSDs, 16 Gig of Ram and Windows 8.1. I too had the black screen of death for a long time and have read many forums, and nothing worked until my last attempt. I am an Intel Channel Member and Partner and a Microsoft Partner, and this has fixed the problem, but it only applies to boards running the Intel Graphics 4000 video.
1. Go to Hp's website and make sure you have the latest bios update. I did, so at boot up, I held the f10 and reset the bios to default settings, hit f10 and saved.
2. When booted into windows, I went to the Intel website, support, drivers, and searched for the Graphics 4000 driver. Their driver was later than Hp's so I downloaded it to my desktop. I then uninstalled the hp driver through the Device Manager and removed everything, and rebooted the computer. That gave me back the Microsoft basic video driver. I then installed the Intel driver I downloaded, and not only did it removethe Microsoft basic Driver, but it installed correctly and gave me a control panel for the driver.
3. Since then, about 2 weeks ago, I have not had a black screen since. The HP Driver is out of date for Windows 8.1, but this DV7 has been the best laptop I have ever owned.
Good Luck Dale

Hi beginner_2012,
Thank you for your post, I will do my best to assist you.
I grasp that you were getting the error "display driver amd driver stopped responding and has successfully recovered" quite often. Then a few days later you got the blue screen then the above error message, after 2 -3 more errors the screen is now blank or black. Here is a document to assist you with this.

TS1363 while updating my IOS to IOS 6 the updating process couldn't be completed for unknown reason and my iphone has nothing but a black screen with an apple and a meter that shows no progess. it completely froze!

When updating my IOS 5.1.1 to IOS 6 and after the download completed the updating of the iphone couldn't be completed for unknown error and the device froze and all i have now is a black screen with an apple and a meter that shows no progress I can't switch off my iphone or do anything!!!

Hi,
I had a similar problem last week with my nice shiny 3 week old iPhone 6. I noticed the Apple logo was on the screen, but it did not progress like a normal boot up. I restarted the phone, and it showed the Apple logo, then a red screen then cycled back to the logo and kept looping. I got the phone to the iTunes connection stage by keeping hold of the power button and the home button until the apple logo appeared then kept holding the home button. iTunes recognised the phone, and wanted to restore, but this was unsuccessful because the phone would keep looping to the red screen and iTunes failed. After loads of Apple support, I was told it was a hardware failure, and like you I live more than an hour away from the store. None the less, I made an appointment with the Genius bods, and they replaced the phone. They said they had never heard of the problem, but really, take a look at these forums and you will see that it is a common problem and I suspect they are keeping it under wraps...
My issue is that as a disappointed customer with faulty goods, why should i have to stick to an appointment to get it replaced? What other store would you have to do this?
The "Genius" didn't even want to see the phone powered up before offering a replacement... Oh, and it turned out they didn't have the exact same model as a replacement so they were going to send me out of the store empty handed.... I kicked off BIG time, and they very reluctantly gave me a phone from the sales stock, rather than the repairs stock..
Not a happy Apple customer anymore, and I feel the more people who know about the lack of service and customer care the better. They need to get off there high horse and join the real world!

[solved] Black screen when booting installation

The basic problem. I have a HD6870, my monitor is connected through DVI (& my second one through HDMI). No integrated graphics.
After I try to boot the x64_86 version, the screen goes black after 'booting kernel'.
Things I've tried:
radeon.modeset=0 (gives drm:radeon_init [radeon]] *ERROR* no UMS suppot in radeon module)
radeon.modeset=1 (black screen)
nomodeset (drm:radeon_init [radeon]] *ERROR* no UMS suppot in radeon module)
disconnected second screen (black screen)
video=SVIDEO-1:d (black screen)
i915.modeset=0 (I have no intel, but black screen)
acpi=off (doesn't work either).
It is driving me crazy. Can someone help me?
EDIT:
Solved by upgrading BIOS

Should this be on or off?
Edit: Only thing remotely close I could find was legacy USB settings, but those just disable my keyboard in the arch install.
Lone_Wolf wrote:Your video card does have crossfire capabilities, do you have 2 videocards in your machine ?
1 videocard
Lone_Wolf wrote:Another possibility :
Maybe linux does send output to a wrong monitor. Could you try booting with only 1 monitor connected ?
I initially thought the same, tried with DVI, HDMI single and double monitor, but it didn't work.
Lone_Wolf wrote:if still black screen with 1 monitor , try a different connection (your card has 4 it seems : hdmi, display port, dvi-d & dvi-i ).
See above.
EDIT 2: putting HD in AHCI mode makes just the screen black. Backlight stays on. In Knoppix and Ubuntu it makes the kernel hang at booting kernel _
