S10-2 display backlight out

Okay, so I received a client's computer from a corporate environment with the problem that the display had gone black. Now, the problem isn't that it's entirely black, but that the backlight is off. I know that this person has taken very good care of the computer and there have been no prior issues with flickering or anything else. This combined with the circumstances leads me to believe that this is probably not a hardware issue.
The computer is regularly used in conjunction with a projector, and it is in disconnecting from the projector that the backlight failed to resume normal operation. An external monitor works fine, but attempting to run it in clone mode produces flickering.
The system was rolled back to prior to the incident, not that I expected for that to do any good. All of the power options have been checked and double-checked. I reinstalled the display driver, which was already the most current. Will get back to you after a BIOS update but I was hoping maybe someone could shed some light on the problem in the meantime. I see that there are a number of glitches with lenovo displays, but none of the problems or solutions seem to be directly relevant to the current issue.
Oh, and the backlight is certainly off, not dimmed. Even the BIOS screen does not light up. Any ideas before I have to open it up?

A couple other things worth mentioning. The Intel display information cannot get the maximum vertical/horizontal information for the netbook's display, and the device manager at any time lists ~6 monitors. Once again, any help is much appreciated.

Why won't my display backlight come on?

I have a unibody MacBook Pro purchased in late 2009.
Sometimes when I wake up my laptop I can see that the display has come on but the backlight that makes the display bright is not on. On other words, the screen is completely dark, but under the right lighting I can see that the LCD itself is on (windows are up, the cursor is moving around the screen) but there is no light making it all bright (i.e., the display backlight is off). When I put it to sleep and wait for the indicator light to start pulsing and then wake it up again it will off then come on, but of course I shouldn't have to do that.
Perhaps related or unrelated is my keyboard backlight also doesn't work. I can turn the brightness up and down using the F5 and F6 keys and the indicator will come up on the screen showing the brightness going up and down, but the keys themselves are not lit at all.
Was there a recall sent out about this issue? I do have AppleCare.
Thanks.

I have the same thing, not only my current Retina MacBookPro (Mountain Lion) but on my previous 2008 MacBook black (Lion). I find it very odd that I'd have the exact same issue on two different computers; there must have been a setting on the old one that got migrated to the new one somehow?

Under Windows 7 Ultimate x64 and Boot Camp, my 27 inch Apple LED Cinema Display checks out as a Generic PnP Monitor and is shown as NOT HDCP compliant. I haven't been able to find any kind of an .inf file to use. Does anyone have a solution?

I am having this same issue. Im not sure if this is the cause but I think this is keeping PowerDVD Ultra 11 from playing back Bluray under Windows 7 / Bootcamp

27 inch thunderbolt display blacks out after Thunderbolt Firmware Update 1.2

Bought 2 new 27 inch TB displays for two different machines and after a couple of days the Thunderbolt Firmware Update 1.2 appears on my Mac Pro with one of the displays installed. So I install the firmware update. Now my display blacks out periodically and I keep getting Graphic Display Errors with a request to sent the errors to Apple. Running a 32 GB Mac Pro (late 2013 circular style) I have three monitors connected (two 20 inch cinema displays and the new 27 inch display). This machine is supposed to be able to handle three 4k monitors or 6 standard TB displays. I've seen the posts about the blacking out with this monitor but I didn't have any problems before the firmware update and now I've got them pretty regularly. I had the blacking out problem on an earlier monitor and took one of the monitors back and Apple gave me another one and this is the replacement. Same problem, but this one only started after the update. I'm hoping someone from Apple reads these messages and can let me know what's up.
BTW, I also have an older 27 inch Apple monitor that ran perfectly on this machine so I'm disappointed that I spent all this money and now get the blacking out issue.

I have my Thunderbolt display connected to my MacBook Pro and have been experiencing the same issue, getting worse over time. The folks at my local Apple store did not know what to do about it. So, I looked around and tried different thing.
The one thing that seems to be working is to System Preferences > Build-in Display > uncheck “Automatically adjust brightness.”
I hope this helps.

When using private browsing to view image results in Safari 5.1.3, only the first two rows of results are visible, the following four or so rows display greyed out place holders, and the safe search button is inoperable. Suggestions?

When using private browsing to view image results in Safari 5.1.3, only the first two rows of results are visible, the following four or so rows display greyed out place holders, the remainder of the results page is blank, and the safe search button is inoperable. When I turn off private browsing and refresh the page, everything works again.
Anyone else having this problem?

I have got the same behaviour after the last Safari Update to 5.1.3. It seems that Safari now handles some scripts in a new way. If you debug the Google Website, you will see, that there is some Javascript Error, that seems to prevent to write into local cache. After some searching I wasn't able to finde a solution for this problem, other then disabling Javascript while private browsing to prevent the script loading. You then are able to use Google with the old layout. The option to disable JavaScript can be found in the Menu "Developer", wich has to be enabled in Safari in the options first.
In my opinion this is a bug that is now occuring, because Apple changed something in private browsing and that has to be fixed by Google now, to run again. Or we will have to wait for 5.1.4, as you can read online Apple will change and bugfix the javascript engine in that version, perhaps this fixes the problem as well. I hope so!
If anyone is in the developer program perhaps you could test this with the beta of 5.1.4 and tell us if it works.

Hi I was using whatsapp on my iPhone5.I was not able go to the main menu by pressing the center button so I hold on to the button for 2 seconds.Then the whole display turned out to be black

I was not able go to the main menu from whatsapp by pressing the center button so I hold on to the button for 2 seconds.Then the whole display turned out to be black & white. how can i fix it?

Hello monicaa003,
Thanks for participating in the Apple Support Communities.
If your iPhone display turned black and white after holding down the Home button for 2 seconds, first try pressing the Home button again to go to the main menu (Home screen.)
For reference, holding down the Home button for 2 seconds will trigger Siri if that feature is enabled:
About Siri - Apple Support
If pressing the Home button doesn't return you to the main menu, try restarting or resetting your iPhone:
Restart or reset your iPhone, iPad, or iPod touch - Apple Support
Additionally, if Whatsapp is not responding or working as expected, see the troubleshooting steps at this link:
If an app you installed unexpectedly quits, stops responding, or won’t open - Apple Support

Display blacks out

so on my ibook g4 mid way through using it the screen blacks out (there is a very faint glow) this is happening more regularly now and atm as a temporary fix i just close the lip and open it.
iv looked through some forums and it seems like a problem that i cant fix myself...
but i was wondering can i just connect the laptop to an old display i have? or that display black out as well.
any help would be great, thanks.

Welcome to Apple Discussions!
When the display blacks out, can you shine a flashlight through the back and still see your desktop? If so, you likely have a problem with the back light or inverter or possibly a cable, which will affect the built in display. Since you can see your display at times, I imagine that the graphics chip itself is still working OK.
Is your old display an external display? If so, it should work.
Good luck!

DISPLAY Blacks out sometimes

Most of the time when I sit back down at the computer desk my display black out for a second. The light turns of, but it comes right back on. Someties it does it several times before it stops. I know thta there is alot of static in my apartment. Does anybody know anything about this? If so, is there anything I can do to prevent this?. It is pretty annoying. Any help would be appreciated.
Oh yea, the display is a Starlogic

I have a Mac Pro, and a Mac Mini. I have owned tha Mac Mini for about two years. I have found the same issue with my mac mini. I do believe that it is normal, and it has something to do with the shared memory. I ran it for over a year as my main Mac, and I experienced the very same thing. I don't think it is anything to worry about, unless it happens over and over. My Mac Pro does it form time to time, although very very rare. It also could have something to do with the display, analog vs digital etc. I believe the digital signal experiences very short interrupts every so often, and that in my experience is normal

My 6070 navigation display blanks out after 5 seco...

My 6070 navigation display blanks out after 5 seconds. Not enough for a 'silver surfer' I am not able to find the adjustment, and it is not in the handbook. Can anyone help. Many thanks
Solved!
Go to Solution.

A reply from service would indicate this a feature of the 6070, back light being turned off. The time out cannot be altered. This feature is unsatisfactory as it times out too soon for slow fingers!

Display, Backlight & OS issue

Hi all,
So, I opened my Macbook Pro 13" Late 2011 this morning to find the screen behaving strangely. There was a blue tint spreading from the left side, like ghosting, but more streaky.
Anyway, first thing I tried was to shut down the Mac and start from a fresh boot rather than from Sleep.
I power up and the screen doesn't even switch on. No flicker, no power. Also, strangely, the keyboard backlight doesn't work either.
PRAM reset and SMC reset both tried - both didn't change anything.
So, I plugged the Mac into an external display and that functions okay - albeit the O/S refuses to boot because of a permissions error that cannot be fixed using Disk Utility.
I'm in Single User mode copying my data manually to an external hdd ready to reinstall Mavericks.
My question, ultimately, is three-fold.
1. Are the LED display backlight and keyboard backlight linked in any way by hardware that could have failed?
2. Is this hardware part of the logic board or can it be replaced separately?
3. Would the issue with disk permissions be linked to the display problem and could a reinstall of Mac OS fix the display issue???
Any more info you need, i will be glad to provide. Bear in mind I do not have a functioning OS to give logs etc.
Thanks,
James

You should do what's easy for you. Amazon or service center.
A product is replaced withint the first 7 days of purchase if proved defected.
You have warranty, so you should probably go to Sony service center and see what they say. Most probably you won't need to contact Amazon. While the Amazon deal is good as well. Get the money back and buy the SW from Sony center.

Apple TV on display times out

Apple TV display times out after a period of time.

Hi TonyWash,
Welcome to the Support Communities!
Is the Apple TV timing out while you are Home Sharing, using Airplay with a device, or working directly from the Apple TV menu? Without knowing the specifics, I'll provide some basic troubleshooting for your Apple TV:
One of the first troubleshooting steps is on Page 26 of the Apple TV User Guide:
manuals.info.apple.com/MANUALS/1000/MA1607/en_US/apple_tv_3rd_gen_setup.pdf
Try resetting your equipment by disconnecting Apple TV, your TV, your wireless networking equipment or base station, and your router
from the power outlet. Wait 30 seconds, and then reconnect everything.
Additional troubleshooting steps can be found here:

I hope this information helps ....

Can T420 use 3 display with out a dock.

Can T420 use 3 displays with out a dock.
One on a laptop display, one via VGA port and another one via DISPLAY port.
I use T420 4178-BYT with Intel HD Graphic 3000 (no nvidia).

You have to re-activate it with the original sim card, or one from the same carrier it's locked to (unless it's not locked, then any GSM sim card will do). The sim card itself doesn't have to be activated, it just has to be the correct one and be inserted. After that you can use it as an iPod Touch. See http://support.apple.com/kb/HT3406.
