Display back light issues

My display has been intermittently shutting off the back light. The display will drop to black, and when I look closely I can see the display is still showing, it is just extremely dark. The only thing that seems to resolve it is to close the screen so the hard drive sleeps, then opening again. I can also restart it. Or it sometimes comes back on by having a force quit and having the finder relaunch.
It also sounds like when the back light shuts off, the fan inside the computer begins to run.
I tried to reset the SMC, but to no avail.
Any and all help appreciated!

Hopefully it is under warranty because what you describe sounds like the begining of a failed inverter board. The inverter is a high voltage AC power supply that powers the flourescent backlight lamps.

T40 back light issue

I have two(2) IBM Thinkpad T40's and they both have the same issue. When I first boot up, the display screen (back light) comes on but after a few seconds, they turn off. I would like to know what is causing this and if it reasonable to fix. The laptops work fine when I hook an external monitor on them but I would really like for them to function the way they are supposed to....Any help would be greatly appreciated, Thanks

if your backlight is pinkish then it is a failing CCFL backlight, which you can either replace the CCFL tube (around 20 dollars from ebay) or replace the whole LCD screen or the top case (around 150 dollars).
The last option is the easiest as it means you don't have disassemble the case, which is a somewhat delicate job if you haven't done before, also the top case assembly would also include a new inverter.

Macbook display's back light suddenly turn off?

I using window7 via boot camp (latest) but when I'm using it for a while (an hour) suddenly the display back light is turnoff (like you set brightness to zero). I can see that display is still working fined but the light just down. Pleas help it happen to me several times. My mac is 2008 white model btw.

Hey!
I've recently had a similar problem.
I took it into an Apple Supported Computer Shop near me and they basically said that there was something wrong with the backlight and it turned out that my LCD Panel needed replacing (which has worked out to be quite expensive!)
I would take yours into an Apple store as soon as possible, as my screen got worse the longer I left it.
Hope you can get yours sorted

Photosmart c6380 lcd display not lighting up

I have a C6380 all in one printer and the lcd display back light has been intermittently going off and on. The display still works and you can read everything on it, but it is just hard to read when the display is not being backlit. Sometimes when I tap on the screen or flip the display up and down the light will turn back on, but only for awhile. I have tried searching for other posts about this type of problem, all to no avail. I have even gone as far as trying to find a replacement part for it, nope. I just don't want to replace the printer because it is only about a year old and works great. Any help would be greatly appreciated.
Thanks.

If the printer is less then year old, then I suggest you call HP and get the printer replaced. If you exceed the 1 yr. warranty, then the printer replacement will not be free of charge.

Back light remains on when display turns off when on battery

Hi,
Sorry for the long subject line, but it basically sums up the issue.
I'm using Windows 7 64-bit on a T61 with nVidia Quadro NVS 140M discrete graphics. I installed the latest Windows 7 drivers from Lenovo, including the driver for the video card. This was a completely fresh install of Windows 7.
Everything seems to be running great, with the exception of the LCD back light when I'm on battery. I have the power settings set to "turn off display" after five minutes. When I idle for five minutes the display indeed goes "black", but I can still see it "lit".
With the back light still active I'm having to close my lid to ensure my battery lasts a decent amount of time.
Has anyone else experienced this on Windows 7 and better yet know how to fix this?
Thanks in advance.

Could be any number of things. Something failed on the monitor (power supply perphas). Maybe the cable fatigued and a wire broke inside. Maybe your video card has failed.
In other words, too many variables. You need to eliminate them as best yo can. Try the monitor on a different computer. Try a different cable and/or check cable connections. Try another monitor on your computer.
Try a smc reset but it probably won't change anything.

My iPad Mini display is dim so i can barely see anything and I maxed up the back lighting is it broken already??

Bought an iPad mini not long ago and the display suddenly went "black", there is absolutely no brightness in the display rendering it useless. I can make out the icons when i sit down in the dark and i can see the back lighting is set to max. I live in denmark and we have no apple store, its still in the warranty period, but where do i take it for repair? Can it be a software bug? I want to fix the problem fast. When i sit in absolute darkness with the wall plug connected I can see one backlight lighting up from the buttom right corner where the speaker is.

Assuming that you have a credit card in the UK, with a valid billing address for that credit card that matches the credit card statement ....
Launch the app store app. Go to the Featured Tab. Swipe to the bottom of the screen. Your ID is accessible in the lower left corner. Tap on the ID. Then tap View Apple ID. Enter your password. Go down to Country/Region and change the store to the UK in there.

Back light only after using thunderbolt display

Hello,
I have a new 2012 Macbook pro 17 and a 27 inch thunderbolt display.
The Macbook was working great. Then I connected it to the thunderbolt display and did clamshell mode. That worked well too. But.. then I powered down the macbook, disconnected the thunderbolt dislplay and tried to boot back up again. The mac book powers on, the back light comes on, I hear the chime then that is it. The back light stays on nothing else happens. Resetting the PRAM can not be done. Any of the boot options are ignored. It is like the keyboard is non resposive. I tried all the reset and boot combinations available but nothing works.
The light on the front of the macbook comes on then goes dim. The apple logo on the lid stays lit, and if I close the lid, the apple logo goes dim and the light on the front lights up. Weird, it is almost like it goes to sleep when it turns on. I tried conntecting the thunderbolt again but no joy. I am really disappointed. This is less than a month old and its already going in for repair. It should be replaced.
Me No Gusta!

Well, I tried the other reset method too. I removed the battery which was extremely easy. I found a tri tip screw driver I used to open Nintendo Wii's this was a perfect fit for the 3 tri screws that were used to hold in the battery.
Anyway, it still did not work. Wow, I gotta tell you, this apple ****, is complete junk. I just turned a Lenovo into a hackbook. It actually seems faster than the i7 macbook that is screwed up. Never again apple, never again.

Display's back lighting no longer works.

Have a MacBook air that is completely functional except for the fact that the display's back lighting is dead. Can see the desktop fine if you point a nice flashlight at the screen.
Is there a part I can order and replace to get a functional back light on my display again? Or am I stuck having to pay $700+ on an entire new display assembly? Perhaps just the LCD component of the assembly would be required or even better a simple back light panel/cable?

Not knowing which model MBA you have can mean the difference between an answer and none.
For the current models, it is probably more practical to replace the display panel as a whole than to disassemble it for just the backlighting components, if even doable. A replacement panel is around $500, from the likes of ifixit, plus the labor to install it for a current model MBA.
But if it is just a cable, as you speculate, only disassaembly is going to determine the feasability of a simpler repair.

When back light is off (during use) charging indication is not displayed on

ipod classic used to show chrging symbol on main screen when back light goes out.
It does not show this feature now, although the ipod small green battery when the back light is on shows that the battery is charging.
Can anybody please tell me how i can restore this feature.
I have tried the factory reset, and also local ipod reset- does not fix problem
Please help, thank you

What on earth do you mean by shattered? Can you post a picture?
It's always possible that the connector was damaged but not to the point that chargers wouldn't work. With continued use, the damage got worse until the connector could no longer feed electricity into the phone.
It sounds to me like you need to get your phone replaced but only the folks at an Apple store can say for sure.

Slate 21 Pro screen back light on when sleeping

Hi James_caI found out a couple of days ago that our service inventory had not yet been updated with the new Scalar FW revision. I suspect that at some time you will experience the same issue...just a matter of when. I'm sorry if I was not clear in my earlier instruction. I should know more tomorrow about when our service inventory will be ready. Rest assured that if you experience the issue again, the next replacement will be correct. Again, my apology for not communicating clearly.

I have Slate 21 Pro. It is awsome all in one desktop with Android system. However it has the problem with sleep mode. Say I press power button to put it into sleep mode. The light on the power button change to red from white. But at some point, could be a couple of minutes or one hour, the screen back light will turn on though the screen is still dark (nothing displays). And at this time, the light on the power button will become white. And the worst thing is it'll never go back to sleep mode once it is in this state. I used a Electric Meter to test the power comsuption. At running time (when I use it and power button light in white), it consumes aournd 26 watts. At sleep time(power button light in red), it comsumes around 5 watts. At the state of dark screen with back light on ( the problemmatic state I describe above), it comsume almost the same as running time around 24 watts. This is too bad for an Android device. Though I'm able to pay the bill, but why should we waste energy and money? I report the problem. HP sent me another one. But the same problem there. I guess it is caused by the latest OS update. HP really should fix this. Does anyone has this issue? I'm so supprised that no one report this issue.

Macbook Pro 13" Mid 2009: back light problem

Hey guys,
I was hoping you could offer me some advice.
My 13" Macbook Pro from mid 2009 has been having some backlight issues. Sometimes, after opening the screen, the backlight won't turn on. If I shine through the Apple logo on the back with a torch, you can see the log-in screen, so I'm pretty sure the problem lies with the back light.
I have tried ressetting the SMC and PRAM, yet that hasn't helped. The only way to get the backlight to turn back on is to remove the cover, unplug the battery, hold the power button for 5 seconds, plug back in the battery, put the cover back, and then turn it on.
So far I had to do this every 2 months or so, yet now the screen seems to die more and more often. As you can imagine, it's quite a pain having to go through this process over and over.
Again, any advice to fix this issue would be fantastic.
Thanks!

I appreciate the response, but my issue does not appear in the linked article as a reason to reset the SMC. Resetting the SMC seems like something too radical to fix something that should "just work". My MBP generally takes too long to wake up or doesn't wake up at all. If it doesn't wake up, I hold the power button and restart. Very annoying, since my wife can resume work on her PC faster coming out of Windows 7 hibernation mode.
Thanks, Apple!
