I have had my Macbook for almost three years now, and for the last month, the backlight for my screen has gone off. However, when I put the brightness down to 0 when the light is off, and put it up by 1 it sometimes turns on for a couple minutes/seconds/hours. Any help? By the way, I am using Boot Camp, I do not know if this happens on my Mac Side, because it comes up with a "stop" sign when I try to boot it up.

I own a macbook pro unibody A1286. I spilled some soda on it and I followed everything that you would do when a liquid spill happens. After a few days I turned on the macbook pro and I hear the charm and can see the screen with light on it. The back light had gone out on the unit. At first I thought It would be the screen, so I ordered a new screen and tried it out. With the new screen it is the same, the back light for the lcd wont turn on. Everything else on the macbook pro is functional except for the back light.
I even own a mini display port to HDMI adapter and hooked that up to my TV and it worked perfectly. The isight camera works, all the ports work, speakers work, optical drive works. Just the Back light on the LCD does not.
this is my first time posting,so my bad if i do anything wrong.
My backlight doesn't work when i tilt the screen less than 90 degrees. is there anything i can do besides take it to the apple store? I'd rather my dad didn't find out
I've got two iMacs in my posession currently from getting replacement machines. Both have screen issues as follows: iMac A - dead & stuck pixels, feint grey horizontal bar running along bottom portion of screen, bottom left corner has noticeable backlight bleed. iMac B - dead & stuck pixels, yellow tinge in bottom portion of screen. So here are my questions. Which iMac should I keep and submit for repair? (does it matter and why or why not?) How does the actual repair get done? For example, if I submit iMac B for repair, could I end up with a grey bar or backlight prob like in iMac A?
Are there multiple layers to the display when they fix specific issues? For example, let's say the dead pixels are on one layer while the yellow tinge is on a different layer, or are both issues on the same layer? I ask because if there are two or more separate layers, there is more of a chance to mess up so I may want to submit the iMac that has the least amount of issues.
Lastly and most importantly, has anyone submitted their iMac for screen repair for these issues and got it back 100% repaired? (no dead/stuck pixels, yellowing, grey bar, backlght bleed) These are #4 and #5 in terms of the number of replacements I've gotten now and I'm sick of it so I may opt to go for repair on either of these existing machines instead of going for replacement #6. But do you think a 6th replacement would be better than going for repair on either of these? Or not?
Macbook Air 11inch 1.6Ghz Model
I have tried a SMC reset 3 times, I have tried deleted the plist file and I have tried the finger over the isight lens and nothing is working.
The buttons work fine and it increases and decreases on the screen, it is just there is NO LIGHT whatsoever!
I don't know what else to do and don't want to send my laptop off to get fixed if it is just a simple thing I can do.
Info:
MacBook Air, Mac OS X (10.7.3)
My Air's screen is slightly darker at the bottom (only on a few millimeters, but still). It only happens on a white/light background though (I don't have my dock at the bottom). In comparison, the screen of my MacBook has a very uniform backlight. Does anybody else have this issue?
View 2 Replies View RelatedMy keyboard backlight isn't working... whenever I try to turn it up it gives a circle with a line through it. I have read that there is an ambient light sensor that turns off the keyboard backlight when it is too bright, however that has NEVER happened before and I have used it in direct sunlight and the backlight still obviously works. It's not even bright right now but it won't work. This is very frustrating, there should be no sensor that turns it off it should be the brightness I tell it to be.
View 8 Replies View Relatedi have had a 13" Macbook pro for around a year now, and i never really noticed that it didnt have a backlight on the keyboard until my mom bought a 17" one (what a biter, amirite?) and it had the awesome backlight. I've tried researching this and i've downloaded labtick and it doesn't work.
Edit: I've also never spilled anything on the keyboard or anywhere. It's been like this since purchase
My keyboard backlight buttons dont work. The keyboard backlighting works when I'm in low light conditions, but I can't control them with the buttons. When I press them it comes up with this:
View 3 Replies View RelatedThe backlight still lights up behind the keyboard but only brightly in a V shape in the middle of the keyboard, the rest of it is very dim.
This happened to me a while back and I just got the laptop back the other day. They had put in a new keyboard (along with a new hard drive and optical drive - but those are another story).
Just now, my backlight came on since I turned off the room's main light and turned on a small lamp and lo and behold...the backlight is messed up again! Same as it was before, I know for a fact it was working earlier today.
All I've done is change the ram and use migration assistant to get a couple things over. I'm not sure how I could have damaged the light by taking out the 3 screws for the ram door...I didn't put barely any pressure on them. I'm not sure if either of those two things caused it but I'm shocked.
Now I have to give up my computer again. Nearest apple store is over an hour, it was 3 weeks last time I gave my computer up (gave it to school's IT crew, who forwards it to apple - but I get a loaner this way).
I kept my macbook (late 2008) turned on overnight on lowest brightness and when I tried turning the brightness back on this morning, the backlight flashed on for less than a second and then turned off again. Somehow I managed to get it to work, but whenever I move my macbook even slightly the problem reoccurs. I've done some research on my problem and I suspect that it's hardware related (maybe the inverter or the inverter cable?), but maybe the LCD itself is broken? Does anyone else have any experience with this?
View 1 Replies View RelatedI read on the internet that this is probably caused by lightbult or inverter board, but that information was on macbook or macbook pro, i couldn't find any information if its the same issue with macbook airs.. Has somebody had similar situation? How have you solved this issue?
View 7 Replies View RelatedI have a 2008 White body model Macbook with 2 gigs of ram and 2.1 core duo processor. My problem is that the screen won't turn on...when I start up my computer it lights up for a second, but turns off before the apple sign shows up. If I look really close I can see everything. Oddly enough, if I press the brightness button so to decrease the brightness to the very last bar and then hit the f2 button to turn up the brightness by one, the light will turn on for a few seconds, if i continually go back and forth, I can sort of use it enough to do something with it (thank god because I had all my work for school on it). I have included a link with this thread so you can see what I mean.
View 4 Replies View RelatedI've installed OSX successfully many times but this one, with a new WD disk gives me trouble. After the gray screen is gone and the installation menu starts, the back-light turns off and I can't do anything about it. Any idea why that happens and how I can deal with it? I am working on a Mid 2009 13" Macbook pro with 2.26ghz and 8GB of RAM.
View 5 Replies View RelatedI've had my new 13" MBP for about a month now and I am noticing what looks like backlight bleeding spots at the bottom of my screen. It is most noticeable on the bottom left and appear blue-ish on a black screen at maximum brightness. It is getting irritating when I am watching movies at night. I have the 9CBD screen. Others have said they have no problems with this screen model. So is this normal or is it a defect? If it is a defect, what can I do to fix this? My 14 day grace period is over, so I'm assuming an easy exchange at the Apple Store is out of the question?
View 6 Replies View Relatedi dropped my macbook. The screen was not responding any more but the backlight was still working. Now, i have opened up my macbook, because my insurance company gave me a new one. There is nothing i can see that is changed. So what is the problem here? I am not waiting to bring it to the store with a respond: It will cost you a 1000 dollar.
View 5 Replies View RelatedI have just replaced the display panel in my MacBook Pro (A1260) and now it is behaving oddly at startup. The backlight lights up normally until the boot process gets to the Login screen, at that point the LEDs shut off. I can see the images on the display, (the LCD seems OK,) the only issue is that the LEDs are turning off.
Here's what I've tried:
1) If I boot in Target mode, the screen stays lit. (As expected.)
2) If I reset PRAM, the lamp behaves normally, staying on through that session. If I restart, the lamp-off- condition returns.
3) I have reset the SMC per instructions here, [URL]. No change, LEDs shut off.

It seems my MBA has developed some issues with the LCD, there is a noticeable dark patch on the bottom of the screen and it is really bugging me, normally little things like these I can get over with but seeing how much I paid for this laptop it is very disconcerting. Oh and also, when the screen is off and viewed under a sun/bright light, you can see waves / "ripples" of the LCD, is that supposed to be normal? Just wondering if Applecare will "care" about this issue.
View 5 Replies View RelatedA month or so ago, the backlight randomly went out on our MacBook. If you look very closely you can see the screen, but it's like you've got the brightness on its lowest setting. The backlight comes on as normal when you turn on the computer, or wake it from sleep, but goes out after about 2 minutes. Other than not being able to see what's going on, the computer works fine. I took it to the Apple Store, who said they'd have to replace something at a cost of ?75, which was fine. Just over a week later, they called and said that hadn't worked, and that it was actually the logic board that needed replacing, at a cost of ?385, more than the value of the computer. We decided it wasn't worth it.
Yesterday however, I took it to a friends and connected it to his monitor, and even though the screen was dark on the MacBook, it came up fine on the monitor. To me, it seems strange that it's a logic board issue when it works fine with an external display.
I have a powerbook g4 17 in a1107. The back light does not work. I am not at all sure what the display resolution is. If I install an lcd screen with anything other than the original resolution, will the notebook be able to support it?
View 1 Replies View RelatedI just noticed that on a black background, my 17" i7 MacBook Pro has two areas in the lower middle area of the screen, where the backlight is too bright compared to the rest of the screen. It is very noticeable on a black background and grey.. Is anyone else having this problem?
Other things I noticed:
- there was dust on the plastic cover that you take off the case when you use it for the first time
- the aluminium enclosure was slightly dirty, could be rubbed off though..
- there are two minor 'impurities' in the aluminium (?!).. two tiny grey spots/blemishes basically
- there were a few minor scratches on the aluminium casing.
- the apple logo at the back glows in a much warmer (yellow-ish) colour than the previous generation mbp (?!)
- the screen seems not as bright as the previous generation
- the keyboard backlight seems not as bright as the previous generation
My 2009 MBP would have problems shutting down or restarting. On a shutdown, it would appear to off, black screen and no lights, but if you tried pressing the power button nothing happened. I had to hold the power button to turn it completely, then press it again to startup.Restarts had the same behaviour, it would get to a black screen and I would have to hold the power button and then press it again to startup.I ended up taking this MBP back for another problem, and they replaced it with a 2011 MBP (since I had recurring logic board that failed a few times).Anyway, I swapped the SSD from my old mac into the new one, and I have the exact same behaviour!!Seems to be some corrupt settings or something. So I booted from a Mac installation disc, wiped my hard drive and reinstalled the OS, then I restored from Time Machine, and unticked the option to restore settings.I want to also add, that my backlit keyboard isn't working either.I tried resetting the SMC, but the power light on my charger didn't cycle orange/green, so I'm not sure if it worked. I tried multiple time, following Apple instructions.I also reset the PRAM, which did work.

MacBook Pro (17-inch, Late 2011), Mac OS X (10.7.3), 16GB RAM, OCZ Vertex 3 Max IOPS 240
So I contacted Apple this morning regarding the LCD Backlight Bleed on my iMac (24", early 2008, 2.8 ghz) They made me reset the PRAM, which I figured wouldn't work, and the issue is still there.
They say it'll have to go in for servicing, and I live nowhere near an Apple Store, so they gave me the location of the nearest London Drugs. Am I going to get the same quality of service as I would from an Apple Store? And what is the exact process that they use, do they just replace it with a new LCD?Also, he said that it will be covered under Applecare unless it is ruled as accidental damage, he said that much of the time, the issue is caused by pressure on the back of the case, and that if that was the case, it wouldn't be covered.I can't really see how this would cause it, and I haven't ever put any pressure or anything on the back, but i did buy the iMac used, what are the chances of this being ruled accidental damage?I have the bleed in all four corners of the screen, if that makes any difference.
I have tried a few thinsgs to try and get it to work including reseating the cables and that has not helped. As the title says, the back light works as i can see the screen getting blacker/greyer. Also the external output works as well. I'm not sure what to do at this point because I can't find information on an inverter board for the LCD, only the LED backlight think this could be an issue with the video card 8600M or is my LCD dead and I need a new one?
On a side note I have taken very good care of this computer, no drops, making sure the HDD is parked before moving, having it in a protective case, etc. The only difference is that I gave this to my sister to use and after a few days it died. (seems everything she gets that's electronic dies these days, meaning I probably shouldn't give her anything that has a circuit board in it....)
I was using firefox today (all I had open was facebook and gmail) and iCal was open in another space. All of the sudden my macbook screen went black, but the backlight was still on and the music was playing. I hit the space bar a few times and moved around the mouse and the screen came on for a second or 2, but then went black again. It wouldn't come back, so I had to hold down the power button. When it restarted, everything was normal, except that now the fan is going fast and loud, and my computer is getting hot with only firefox open to macrumors.
View 2 Replies View RelatedJust received my new imac today and everything is perfect, quiet drive, no stuck pixels excellent apart from some bad backlight bleeding which can be seen on black screens. It's particularly bad at the top and the sides.... Does anybody else have this and should I risk sending it back??? I have a 52 inch lcd sony and that doesn't suffer at all from back light bleeding...
View 20 Replies View RelatedI have not seen any posts comparing these two symptoms together, but I am wonding if both exist on the same screens, or if they are infact seperate issues. I returned a 27" iMac i7 because it had both slight yellowing and terrible backlight bleeding. I have seen multiple machines first hand (3 Core 2 Duos week 41s) at different stores (Apple and Best Buy) that had no yellowing and no backlight bleeding. I won't get into how to check for yellowing, you can read about that issue here: [URL]
But to check for backlight bleeding is both easy and impossible not to see if you have it. To check for backlight bleeding, a quick way is to bring up a site like http://www.blackle.com/ or any other black background, and check for an inconsistent white glow on the edges of your screen. I had serious backlight bleeding in the lower corners of my screen, which happens to be where the yellowing was happening. I don't know if they are related, but hopefully we can determine if there is any correlation here.
I did order a second machine, because I know Apple knows how to make a 27" iMac with a perfect screen (as advertised), since I have seen 3 of them in the wild. Hopefully they will be back to the quality that they had is their early production units very soon.
I'm on a IMac OS X (version 10.5.8) and I just noticed a bit of a change in the graphics while playing Heroes of Newerth. I left all the graphic stuff on medium quality, and I've noticed now that when it is on full screen the picture is sketchy. When I minimize the full screen (apple m) i realize its a lot smoother than it is in wide screen (no kidding huh?). Before I thought it was just due to me having the IMac wireless, but I've noticed it's been happening for a week already and I usually get better bandwidth when no one is home. So is this a graphics card issue or what and if so how would i deal with this?
View 2 Replies View RelatedI have a 2.2 Santa Rosa 15" MBP, and an odd thing happened last night. I wasn't running any unusual applications, and had a few things open and was browsing in Firefox. All of a sudden my screen went black, and wouldn't come back up.
The computer is still running just fine, and it didn't go to sleep. The LED backlight is fine, as the Apple logo is lit up and if I change the brightness I can see the backlight changing (the "black" screen gets less "black", if that makes sense), however the actual display panel isn't projecting any picture at all.
I've restarted a dozen times, reset PRAM, and did the unplug battery and hold power button trick, all to no avail. There's no flicker of a picture or anything... it's as if the monitor is completely dead (aside from the backlight being fine).
If I plug in an external monitor, I can use the computer just fine. So it's not like the video card is dead all the way.
I know that the base 2.0GHz MacBooks do not feature the backlit keyboards of the higher-end models, but I was wondering if the actual backlight is physically in these lower-end models and just disabled in firmware or software? Or is it missing entirely?
