Backlight on display failed

I have a 15 inch MacBookPro and the backlight on the display just failed. I purchased it in June and just turned it on last week to a very, very dark display. You can barely make out the screen. I'm able to plug in an external monitor to use it. I'm wondering if the hardware failed or if I inadvertantly hit a combination that turned it off. Thanks in advance.

I am sorry to say that but your laptop needs to be repaired. I had the exact same issue, returned the laptop to an authorized support center and had the Motherboard changed...I waited one month!
I hope you wont have to wait that much...

If its under warranty, its something that the applestore will fix fairly quickly. If not, it all depends on if you are willing to spend that amount of money to get it fixed.

AirPlay Display fails only in one Mavericks account (AirPlay Client Identity cannot be established)

Hi,
I currently running into a strange issue with AirPlay Display and maybe you can help.
I am using OS X Mavericks on a Late 2013 Macbook Pro Retina and trying to use Airplay Display with an Apple TV (V3), all running the latest software revisions.
In general AirPlay Display is working flawlessly in my setup for all types of user accounts (admin, standard and guest). However, in one specific standard user account AirPlay Display fails with the following dialog pop up: Could not connect to "Living Room (Apple TV)" --> (The latter being the name of my Apple TV).
The console output indicates its an issue with AirPlayUIAgents which fails to create an AirPlay Client Identity. Here is the complete log:

I switched between admin and standard user rights for the concerned account but this did not help. iOS Display Mirroring is also working without any issue. I am not sure whether the source of the issue is in OS X Mavericks or the Apple TV.
Does anyone have a clue, what the source of the issue might be?
Thanks a lot for your help in advance and happy holidays,
Jens
PS: Restarting the Macbook or AppleTV nor resetting the Apple TV does resolve the issue.

Thanks for the answer. However, this did not fix my issue. In the meantime I found, that Mavericks is actually not restoring any preference settings in the concerned account: e.g. any settings in the dock, which I apply during a session, are lost as soon as I restart (they survive a simple log-out and -in, but are lost after complete restart/shutdown). The same is true for any other settings I apply e.g. in the Finder.
It seems to me the concerned account has issues with entirely mixed up permission settings, even though I cannot imagine where this comes from since I set up the account quite recently and did not do any particularly special things with it since then. This would also explain why this issue is limited to only one account whereas all other accounts are working fine (including AirPlay Display with Firewall activated). Repairing disk permissions in the disk utility does also not help.

IMac Display failing after 1 year of average use.

I have a mid 2011 27" iMac (the one with thunderbolt) and the display is starting to fail after 1 year of average use (an hour of use every day on average). The display is now much dimmer on the left half of the display (the GPU sits underneath that portion) and also flickers the whole display now and then to a lower brightness.
I am about 45 days out of warranty and basically will have to cough up $500 to have it fixed by Apple. My questions are... Has anyone else ever had this happen to them? The genius bar employee thought that it was something he has seen happen to displays when exposed to heat over long periods of time. So basically playing starcraft 2 and doing video encoding killed my display if you believe that to be the cause.
Are there any conditions in which apple would recognize this as a manufacturing defect and fix it free of charge? Otherwise it looks like im writing a check for $500 next week.

Today a dark streak showed up on my display right in the middle. It is shaped like a zebra stripe but is dark grey and wont go away.
I too have a mid 2011 27" 3.4GHz i7 iMac with a 2GB Graphics card . Im about 50 days out of warranty.
Seems like its perfect coincidence for apple that 50 days after my warranty runs out, the most expensive thing to repair breaks.
After doing some research it seems like there is a lot of people with this model experiencing this problem.
Pretty sad that my 2005 iMac is holding up better than my brand new iMac.
Been saving up for it for like 4 years and I dont have the money to repair it.
I tried everything, I knew none of the stuff i tried would work but i still tried resetting the PRAM repairing disk permissions all that good stuff. I even have an air purifer/dehumidifier in my room so i dont know what caused it.
I didnt think i needed applcare because ive had my other imac since 2005 without a hiccup.
Ive rendered out 3d animations using the cpu at 100% for days and it still runs fine.
Havent even used my new imac for anything that would put stress on it.
What i do notice is that it runs hot all the time. ever since I got it. Sometimes just doing basic stuff such as browsing safari it can get so hot where i cant touch it. my GPU normally stays at around 70C and the hottest its been was 80C which is still safe. The alluminum is supposed to transfer heat better but all it does is retain heat more and get super hot. the old plastic one i have is 10x cooler.
What i did notice today tho when my screen problem happened, is that the GPU temperatue is at 50C and wont go above it. I monitor the temperature with istat and never have seen it at 50C and below unless i am just doing a fresh boot.
What really concerns me tho is how the screen went out so close to when my warranty expired.

2nd External Display Failing After Yosemite Upgrade

I have a late 2009 iMac 27 (3.06) that ran perfectly fine with TWO external displays (both HP Pavilon 27 xi's). Upgraded yesterday to Yosemite and now 3rd monitor (2nd external) fails to find a source feed. Any advice out there? (#1 external monitor is connected via direct mini DVI to HDMI via a Rocketfish adapter; works perfect; 2nd external monitor is connected via a USB to CableMatters HDMI to DVI adapter to back of HP monitor - worked perfectly for months until last nite; (HDMI to HDMI never worked). Advice? Thanks.

I have used an Acer S230Hl on three Makbook Pros via the VGA wire and a thunderbolt adapter. No problems at all with 10.6, 10.7. Worked perfectly.
With 10.8 the display would not wake up from sleep, most of the time. I found an annoying work around that helped maybe 70-80% of the time: unplug the VGA+adapter monitor feed, and then go to system preferences>>displays>>Color>>open the S230HL profile and then simply plug the monitor back in. I also delayed the sleep feature for 2 hours to prevent the problem, but it happens most of the tiem when I close the lid or put the machine to sleep manually.
Now with Maverick (10.9), even this elaborate this trick does not work. Why the loss in compatability Apple? I've called applecare twice and the techs have not been able to help--and now are not responding or calling me back. Having to reboot my mac 3-4x a day is a major problem. Anyone have ideas for me?

B570 display fails after dual monitor display

After running my B570 (1068) with an extended display, the unit went into hibernation. On wake-up the laptop screen is indecipherable garbage. The second display will run to show BIOS startup but then reverts to the built-in screen - which is illegible. Toggling the F3 key does not get a good screen.
I read another post suggesting this is a hardware failure. What parts have failed?
Solved!

Led kdl-ex650 display failed

I purchased a 32" Sony LED TV KDL-650 in may 2012.Now i am seeing a vertical bar of white line and distortions on the screen.I complained to the customer care and they came to inspect the TV.They told that it was the display panel problem which should be changed and it would cost around 14k. I mean after buying a top quality product and that failing within 3 years of use is totally unjustifiable. I never expected this from Sony.I have been a regular customer of Sony from the past.I found out from the repair guy that lot of people are facing the same issue with this model.So i believe that it would be a manufacturing defect.And i request you to kindly considering repairing/replacing it because even if i buy a new panel i doubt that it will aslo fail like this.Terribly disgusted with the quality of product from Sony.I seriously would reconsider buying from Sony in the future if such is the quality of their product.i think the concerned authorities would take it seriously.

I purchased sony bravia led backlit kdlhx750 32 inches 3 d tv, 2.3 yrs ago. 3 days ago it started to show twin pic,lining and distorted resolution. I got frustrated bcz same problem occured with one of my frnd's sony tv 2 mnths back n he spent 12000 for this.
I observed one thing abt sony hardwares by using several prodct of sony, tht it is not last going. My sony hometheatre stoped working within 1 year, my walkman stopped after 6 months, my this led also got malfunctioned in 2 yrs.only one lcd 20 inch bravia which i purchased in 2009 is still functioning.
Other brand like samsung n LG are very last going. My father is using samsung lcd tv for last 8 yrs it is still good working. I have seen these sort of problem only wth the sony users. So now I m totally dissatisfied with sony.now I hv decided to discontinue my loyality with sony. I hv also mentioned this things in my feedback to sony customer-care services people when they asked my feedback.
I spent Rs58000 for this tv just 2.3 yrs back n now after reading about the same problem from several buyers, for me it is very difficult to believe sony n go for repairing on Rs 12000. I hv packed this TV n started using that 20 inch bravia lcd. When I will have sufficient money I will go for other Brand.
Sorry for my harsh feedback...but you can better understand the pain of a 20000 monthly working person who saved that amount in 5 yrs n purchased that tv just for his desire.
I registered my complain by my mobile no -7736009012 ,they told that they are able to trace my complain just by knowing this no.
If there is any cheaper solution is available for me then kindly pls help me.

Display failed on Pavilion dv9730nr

On Pavilion dv9730nr laptop, running Windows Vista Home Premium, the display does not come up in any readable fashion on boot.
The display at first ran OK for several minutes before the screen went blank (or very badly scrambled), but it got progressively worse to the point where it will not boot with a readable display at all. The diagnostics I ran while it WAS working a little said the video board (display board?) was not working properly and needed the services of a technician.
I followed a number of forum posts, and I gather this is not an uncommon problem fir this laptop, requiring a new video board to be soldered to the motherboard. If sent to HP, they replace the whole motherboard -- and the problem often recurs.
Plugging an external monitor into the laptop results in an identical unreadable display.
I've decided to dump the laptop despite it's being only about one or two years old (past warranty) since it appears to be a complete lemon.
My Question:
Is there a way for me to retrieve my important files from the hard drive? I have lots of other HP desktops that I could attach the hard drive to IF it has "standard" desktop-type power and data connectors (??)
OR, can I directly connect a working desktop to the laptop, assuming the laptop actually boots OK, even though I can't see a readable display on the laptop -- i.e. can I use the connected working desktop as a readable display so I can see what I'm doing to transfer the laptop's hard drive files to a different hard drive?
BTW, I'm very capable mechanically and electronically, so I can handle opening the laptop, removing stuff, etc. I'd get a new video board and replace it, but I think the particular laptop is too unreliable to be worth the repair -- from what I read on the Forum.
As a last resort, I'm guessing there are computer places I could bring the laptop or its hard drive to so THEY could transfer my files for me?
I'm done with HP, especially since the new CEO wants to get out of the computer business.
Thanks for any advice or help you can offer.

Time Machine no longer backs up data, but also doesn't display "Failed"

Hello. I've had problems with Time Machine for a while now. First, instead of just performing an incremental backup, almost every day it tries to back up about 59GB of data, far more data than I'm changing. Then it started to fail after the first successful backup of the day. Once it begins to fail the only thing I've found fixes it is completely wiping the backup and starting from scratch. Now most recently it starts to backup (once again about 59GB of data) and then after about 1GB is backed up it just stops, with no message of failure but also not reporting that it backed up anything.

If you are using a Windows partition or the VMware/Parallels equivelents, you might have a big chunk of data out there that does need backing up. Also, if you manually back it up, does it work?

I am running the latest firmware on my TBD and software as you can see. The problem is intermittent and not consistent as you would expect. Thanks.

You do not need to use cleaning programs. They can destroy your computer operation as they may already have done.

When did Apple start using LED backlights for display panels?

I am a relative newcomer to Apple world.
As an electronics professional, I am interested in display technology and progress.
Apple displays have been impressive for some years,particularly the MacBooks etc.
Does anyone know the historical points when LED's were replacing fluoro's?
Thanks folks.

Probably your best resource is the MacTracker dataase as it identifies the display technologies in different models. The LED was introduced at different times with different models. and MacTracker is subdivied by models--easy. Here's its entry for an older Intel iMac showing the TFT instead of LED display:

Mactracker is freeware or donationware depending on your mindset and is here:

For my research needs, it is much more convenient to have it as a free-standing app running under the Apple Discussions window than to use similar sites that require a lot of page navigation.

MSI GX620 Display failed?

Hi All,
I was using my laptop earlier today and i have the laptop screen as primary display and an external LCD as secondary. For the last few days i've noticed a kind of whining / squeak coming from the laptop whenever i restart it from sleep mode.
Anyway today, the laptop screen just turned itself off, and won't come back on. My external display still works fine, and i just made it my primary. The laptop restarts fine, and i havne't done anything to it at all (no bios changes or any other kind of updates). Nothing i do seems to make the laptop screen display any more, its just dead black.
Is there any way to fix this without having to send it off to MSI? I will have to ship my laptop to them since they are not in my city, and that will take quite a long time and be very inconveniant.
Thanks.

Did you try the key to change display from notebook LCD to external, to clone(where image shows on both the external and internal monitor? Doubt this will work, but it won't hurt to try. It is more likely and loose connection to the MOBO/video or a broken wire to the laptop LCD.
Open a ticket to MSI.

Macbook Pro Retina Display fail/glitch

I am between a rock in a hard place.
A friend helped me get a great laptop in 2012.
Now the display keeps malfunctioning. It will scramble up while I am trying to work. Sometimes it resets when I try and close the display and sometimes it doesn't. But even when it does reset, I am never sure if I will go seconds, minutes or hours before it glitches again. Any suggestions?
Here is a link to the video i recorded with my "smart" phone.
My nearest Apple Store is 1 hour away and I need my laptop to sustain myself as a freelance graphic designer. If I could figure this out without going to see a genius or potentially losing my Laptop while they repair it, I would appreciate it.
Thank you!

Macbook Pro display fails to dim fully

MacBookPro5,1; 2009, 10.5.8
When I manually dim from the keyboard key, there's a residual light spot in middle, roughly at the last brightness level before full fade. Grabber doesn't capture what I see, so can't post an example.
When I'm in full dim (with lit spot in middle) and go to lower right corner (to sleep the display), the brighter spot disappears for a fraction of a second, then re-appears as grey. Same when waking it up again.
Known problem? Hardware? Software?
Nothing to worry about or sign of imminent display failure?

I have this problem also and have found that nothing seems to prevent the display from dimming, even while viewing a quicktime movie the display will automatically dim regardless of Energy Saver settings, just seems inoperative in controlling the dimming behavior of the display.

My backlight has completely failed on my 3gs

woke up yesterday morning to find that the backlight on my 3gs had stopped working. the fone works fine otherwise.

Make an appointment at the genius bar and take it in for service.
