NB100 Screen goes dark - backlight not working

My new NB100 (had it about 3 weeks) just started going dark at random intervals. The screen's backlight goes off. In a light room I can still see the outline of the GUI very faintly. I have tried re-booting and it is still dark when I reboot. I have plugged an external monitor in and that works fine, so there's nothing wrong with the graphics card. This morning I turned it on and it worked for about 1 hour then just went blank on me while I was using it.

Hi
If an external monitor works fine on your notebook its an internal display issue. The FL inverter controls the backlight of a display so I think this part must be replaced.
As Akuma said you should go to an authorized service provider. They can order all Toshiba parts and the technicians can exchange the FL inverter.
Here you can search for an ASP:

Auto brightness of screen and keyboard backlight not working

Basically, since I updated to OS X Lion, the auto brightness feature for the screen and keyboard hasnt been working, despite the fact I have it turned on
Thanks in advance for your help

Same problem here. I initially thought the auto-brightness problem had been fixed in 10.7.3, but sadly it hasn't. The auto-brightness works when the Mac starts, but I find it loses control and fails after wake from sleep.
I have telephoned AppleCare several times but they are not aware of this bug. They think a PRAM reset cures it, but it doesn't. As soon as the machine goes to sleep then auto-brightness fails on wake.
I have used the Apple Form to report the bug. It might eventually get fixed if others would kindly report it as well please. Here is the link:

Screen goes dark..not black

Hi
Last night my computer screen went dark. I could still see what was on the screen but it was very very dark. Had to force quit with power button. Computer came back on and was fine. Now this morning when I went to power on, it powered on fine then a few minutes later same thing happened. It happened a few times and then the last time I powered up it hasn't happened. Any suggestions?
Thanks
Update: happened a couple of times today.

Same thing here. Started happening a few days ago. Usually, all I have to do is close the laptop and open it up...doesn't usually work the first time, but after 2 or 3 times, it will come back on and there is no problem. I have no idea what is going on. Mine is a 2008 macbook.

I have read some older posts and from I can gather it could be an invertor issue. Does anybody know anything about this? Also is it an easy fix? No apple store near me so I have to take it to someone local.
Thanks

Screen goes dark, but not blank

As of today, my first-gen iPod nano doesn't quite turn off right. When the backlight goes off as normal, the information stays on the screen. It basically looks like it's always on, even if it's only displaying the main menu and no sound is coming out of it. Apart from being annoying, I worry this will eat the battery or wreck the screen. I haven't found anything that works, and although I can still reset the whole **** thing, I'm loath to. So if anyone knows a fix for it...

Have you updated Photoshop to version 11.0.1?
Try resetting the Photoshop preferences.
You either have to physically delete (or rename) the preference files or, if using the Alt, Ctrl, and Shift method, be sure that you get a confirmation dialog.

This resets all settings in Photoshop to factory defaults.

MacBook Air Boots to OS, then screen goes dark.

I have recently been working on an older style (A1304) MacBook Air with the 128GB SSD. I've been working on Mac's for years, and have worked on hundreds, but this is the first time I've ever come across this particular issue.
Liquid damaged MacBook Air. Keyboard and Trackpad mainly took the brunt of the spill. Popped off the keys, cleaned it all up. Button for the trackpad no longer works, but everything else does. Entire computer was disassembled, no other liquid was found.
MacBook Air boots up normally, and I was using it for a few hours to make sure everything was working fine. Left it to charge. Came back two hours later, and the screen was dark (but the image was still visible, as if the backlight was not on). Could see the mouse pointer moving, but backlight won't come back on. Turned off computer, turned it back on. Backlight works just fine, and it boots to the OS. Within 10 seconds of booting to OS, the screen goes dark (screen goes completely black with no image). Couple seconds later, light on the front starts to "breathe" indicating it's sleeping. Wake it back up, and image appears on the screen, but no backlight. Then it "goes to sleep" again.
Boot computer to a Flash Drive with Snow Leopard Installer and once the blue screen comes on as if the installer is just about to pop up, it "goes to sleep" immediaetly. Though, the backlight and computer will stay on in the Apple Hardware Test for as long as I want. (ran it several times, "no trouble found". Also reset the PRAM, nothing helps.
I was wondering if anyone has ever come across this. Completely baffled on whether it's a software or hardware (or combination of the both) issue I'm having.

The keyboard and trackpad reside on top of the motherboard and all the components of the computer. The keyboard and trackpad are not liquid proof. It is VERY likely that the liquid made its way to the motherboard and has affected those components. If EVER there is liquid spilled on a computer, the last thing you want to do is A. Turn it on to make sure it is working.. and B. Plug it in and charge it. Do the EXACT opposite. Unplug and turn off all power, and, if possible, remove the battery from it. The liquid itself doesnt do the damage...the damage is done when the liquid comes in contact with the circuits and shorts out the contacts and components. You could try to connect to an external monitor, if you have the means to do so, to see if it makes a difference, but it probably will not. I seems that the motherboard is not functioning correctly.

700P Sprint Update 1.10 - Screen goes dark after sync

I updated my Sprint 700P yesterday to V1.10 Palm software. All seemed to go well with the update, until I tried to restore my data with a HotSync.
The sync seems to go normally, but at the end, it says a "reset is necessary"...after the reset, the screen goes dark right after the Palm logo appears. The phone seems to be still working.....just no visible screen.
I spent hours on this yesterday....now have no working phone.....very frustrated.

Post relates to: Treo 700p (Sprint)

Yes
i just replaced my 700p due to this issue and return home to find that nothing has been resolved.
It turns out that the update is rather seriously flawed. There is no way to revert the update so, Verizon (after checking with Palm) replaced my Treo and suggested that I not run the update again.
Now the sync issue that you describe.
There appears to be files associated with your treo on the Palm software on your desktop that are set for installation. This was due to the update i believe. These files: specifically those associated with AudibleAir.pdb are creating havoc during the sync.
The Work-around that Palm suggested to me which appears to work (on the new phone with the original ROM) is as follows:
1) Hard Reset the Treo
2) Re-sync the treo
!> When it asks you to choose the correct id, DO NOT DO SO!!!
3) Create a new ID for the treo and continue the sync.
This way these bad files are no longer set for installation because you are not using the same account as when you ran the update utility.
I would be interested to know if this works with a Treo 700p with the new ROMs installed.
My method requires the old ROMS and Palm in its infinite wisdom has not created any means of rolling back to the old ones. Thus a catastrophic update.

IPhone 3GS screen goes dark...no apparent fix for it

My iPhone 3GS has started having a problem where the screen goes dark. The phone is still active and if you have the right light and strain real hard you can barely see the icons. I have tried everything I know to fix this but nothing works. One thing that did work for about a day was a Reset All Settings, from the General Settings menu. Previous to doing that, I have tried: 1) turn it on and off, 2)hard reset, 3)restore from iTunes. None of these worked for more than a few minutes. I did restore firwmare from the computer but I have not tried putting the iPhone into DFU mode...is there a difference?
Any ideas appreciated.

All iPhones require a SIM for updating/activating.
The SIM does not need to be active, simply insert a SIM card and activate the device. Borrow a SIM from a friend if necessary.

Screen goes dark too quickly while on call

Hi- I am just learning to use my new iphone 4, already did software update. When i am on a call, the screen goes dark within a few seconds so that i cant easily get back to the keyboard, the screen that allows me to go on speakerphone etc. Is this normal? I adjusted the auto-lock in settings but i couldnt find any adjustment for the screen going to sleep while on the phone. Also, is there any way to adjust the number of rings before the call goes to voicemail? Thanks.

hey mehode,
correct me if im wrong..
laptop at maximum brightness or even if brightness level is set at half .. the backlight is off. ? And if you close the lid the backlight will suddenly switch on ?

You don't in the condition it's in. You will either have to get the phone replaced by Apple or pay a 3rd party to repair it.
there seriously should be more than two ways to solve this other wise apple is useless and we will never buy another apple product.
Seriously? It's physically broken!
