Tecra A9 - LCD Screen Extremely Dim

Hi all!
My 4 year old Tecra A9 recently developed a problem with the screen. While using it, i heard a zap and the screen cut out. It hasn't worked since. I've been able to plug it into an external monitor to keep using it though.
But i did find that the screen isn't actually dead, its just extremely dim. If i look really closely and shine a torch on it, I can see what's on the screen. This leads to me believe its something to do with the back-lighting in the LCD screen.
Also, I've checked, and its not a problem with the sensor thinking the lid is closed.
Anyway, I would like to know if anyone has an idea about what the problem specifically is? If so, is this the sort of problem that I can fix myself, or do i need someone from Toshiba to do it for me?
Thanks!

Hi Matt89,
I agree with Akuma. If an external monitor works properly it looks like that the FL inverter is faulty. This inverter controls the backlight of internal display and even it would be faulty you can see the picture but very very dim.
If think the best would be contacting an authorized service provider. The guys can order an original FL inverter that is compatible and replace it for you because the display itself must be disassembled and thats not easy.
If your notebook isnt under warranty anymore dont worry because FL inverter is not so expensive. :)

Nano screen extremely dim

I recently had a problem with my ipod not turning on however now that I've read and followed the directions properly it is back up and running, BUT the screen is extremely dim. Any ideas on how to fix this? I have not dropped, nor washed, nor mishandled my ipod in any way and have only had it for 9 months (birthday gift from my children). Any help would be appreciated. Thanks Lissa

Although I have not experienced this with any of my nanos I noticed that you stated you received yours 9 months ago. It may be in your best interest to arrange for a warranty repair while it is still under the 1 year warranty...just in case it is something that no other fixes can handle. Also, have you tried going through the "5 R's" to see if they helped resolve the issue? I'm not sure that would work but it never hurts to try...

Lcd screen keeping 'dimming'

I'm sure there is an easy fix for this.
I notice if i haven't used my computer for several minutes, the screen dims, and then quickly brightens againa as soon as i touch the trackpad or any keyboard button.
I have gone into the options listed under the battery icon. I have tried to set it to best performance, it still seems to occur, i have gone into custom and and energy saver and set the sliders for putting the screen and computer to sleep for both the battery and the power adapter to 15 minutes. I have locked the settings.
It still seems to occur.
Peculularly, i often go back into this area, and the lock is UNlocked again, without me entering my password.
Is the screen supposed to dim? I find it annoying and would like to turn it off.

I can understand your frustration with this, and with some of the responses...
Check out that link in this thread, I have outlined "improvements" to the situation in the last post.
There is no official solution, and apple did not address my question during my last repair.
I will be setting up another pro care session within the next month and will try to reproduce this for them.
Supposedly this has been going on since the Powerbook Era, and is nothing new. Unfortunately I've only noticed it with the MacBook Pro, and never with my powerbook.
Keep an eye out, and eventually we will find the source of the problem.
Now here's the REAL question:
Does anyone know if there is a log (say in console) of when/why/how the screen dims, much like there is a log of system sleeps???
I think that will answer our question, and find the source of our dimming despite all the appropriate settings UNCHECKED!

LCD Screen is dim - becoming dimmer?

I occasionally have to use my powerbook outdoors and have noticed that the screen on my powerbook has become steadily dimmer - or at least I think it has. I went into System Preferences>Energy Saver>Options and de-selected the "Reduce the brightness of the built-in display when using this power source" radio button.
It seemed to make a difference, but no longer. Is there any other setting I should look at to increase the screen brightness?
Or is there something else I should be doing?
Thanks...

By the by, Where is the "automatically adjust
brightness as ambient brightness changes" checkbox?
It's not in my Displays Preference pane?
It's right under the brightness slider in mine.
Please notice the model and OS version of my
powerbook below, thanks.
Sorry, since this is the 15" Aluminum Powerbook forum, I kind of assumed you'd have a 15" Aluminum Powerbook

My 13" Macbook has a very dim screen. Replace inverter board or lcd screen?

I have a 13-inch Macbook and the screen display has gone extremely dim and is very hard to see. Should I replace the inverter board or lcd screen?

No dice I have it hooked up to an external display and can see that it isn't recognizing the battery. I've installed a brand new battery connector already, and this is the second battery (although they are from the same place, so maybe they had a bad batch?). I've done all the updates (firmware and Battery Updater) but still, nada. Any other suggestions?
I am not too familiar with this specific MacBook battery. When I push the button on the bottom, 4 out of the 5 lights come on, then the one in the middle, then they all go off. When I have it plugged in without the machine on, the light on the adapter is green. I start it up, and it goes to amber.
This is driving me crazy! What are the chances I would get two bad batteries? Or two bad battery connectors? Could it possibly be the logic board? I was thinking no, because it actually works fine without a battery and shuts off the backlight when the battery is plugged in.

G500s Extremely Dim Screen

Hi,
I have a Windows 8 G500s laptop that was purchased this past December. As of last week, the screen would get extremely dim (almost impossible to see what's on the screen). The only resolution was to grip the screen in odd areas and the brightness would return. I'm very frustrated with this issue.
Can someone please help me resolve this?
Thank you.

hi dajonx,
Based on your observations, it looks like there's a problem with how the backlights are controlled within the LCD assembly (could be a faulty controller board that powers up the LED's). This is definitely the case if the problem remains even if you just boot in the BIOS.
In this case, I recommend you contact lenovo and report the issue as you may need to send the unit for service.

T400 LCD screen is very dim, but icon lights for HDD, etc. are working

Hi - I'm wondering if anyone knows what the issue with my T-400 would be if the LCD screen is very dim. Details include:
- When I boot up, there's a faint outline of what is going on, but barely noticeable since the whole screen is very, very dim
- Video card is working okay, because I can operate the laptop when I plug in an external monitor
- The icon lights for HDD, power, battery, etc. are still working
Thanks so much for the help.

First a question: Is it a CCFL backlight or LED? If it is a CCFL, it could be just the inverter, which is a lot cheaper than the panel. If the CCFL bulb goes out, usually (but not always) there is a red tint to the screen for a while first. The LED backlights are less likely to blow and there is no inverter. (The LED backlight is DC and the inverter convers the DC to AC to drive the CCFL bulb) Do you know which kind of backlight you have? If you don't know, send me your full model and serial in a pm and I'll look it up. Don't post it in the open forum. Also, what were you doing when it went out? Were you doing anything except normal work, like taking something apart or hooking something up?

Extremely Dim Screen; intermittent Issue

I'm hoping people still check this board out despite being 3 generations old.
So I dropped my phone and now the screen is extremely dim. I can see it if I hold it up to a light, but it's dim. Clearly the backlight is messed up.
The problem is only intermittent, sometimes the screen works, sometimes it does not. So, it appears there is something that came loose in the drop.
It's not covered by apple care, and I'm not quite eligible for an upgrade.
I guess my question is does anyone have an idea of what I should look for if I open it up to look for loose connections? Or if they have any idea what it would cost to fix (either at Apple or a 3rd party).
I'm not concerned about voiding warranty as it's not covered anymore, and I'm not concerned about it breaking (as I'm going to get a new one here in a few months), but I was just hoping I could fix it cheap and easily, and looking for advice.
Thanks.

Have you tried basics from the manual?
Restart, reset, restore.
Sorry, yes I should have stated that. I've tried resetting the settings, restarting the phone (with power+home key), and erasing and restoring the phone from my backup.
The issue is still there.
EDIT: Also updated the firmware to the latest firmware for the 3G.

How do I fix an extremely dim screen issue on my ipod touch?

I havent gotten my ipod wet. It hasn't been in extreme heat or cold. Today the LCD screen just stopped being bright enough to be able to see it...randomly...one minute it worked and the next it didn't. I tried restoring it and also updating the software but that failed to work. The brightness settings are all the way up. I'm not ********...I use my iPod a lot and it not working is very upsetting...anyone have any other ideas?

Is that through the computer? Because i restored it through the computer but I cannot do it from the ipod itself because I can't see the screen well enough. The light still doesn't work...im definitely not looking forward to a trip to the Apple store >_<

HP IQ775 Dim LCD Screen

Hi!
My HP IQ775 turns ON, splashes the hp logo and then the screen goes dim. Everything is working but the screen backlight does not stay ON. Can't be the LCD inverter as the backlight does turn ON at start. Does anyone have any idea why its doing it. Any help will be appreciated.
Thanks

The inverter is in the screen housing.
Bigger job to remove but not impossible.
10-15 mins if you have done it before.
You need to remove the hinge from the screen before you can remove the plastics.
That meens that you have to unplug and pull thru the 5 wires,
Front plastics off (you can leave the U shaped bit) ,
Front metal shield off,
Back cover off,
Now pull the wires to allow removal from main body.
NOTE:
The wires cannot be streched long enough to attempt removal
so the wires have to come off along with the LCD body.
You aint never going to do it any other way.
Take the screen off the main body and work on it flat it will be easier.
So get the wires free and then remove the 8 hinge screws.
Oh do not forget to support the screen as you take out the screws.!!!
The plastics from the hinge then need to be removed and then you can get to the black screws.
Now the hinge shoud be totaly off.
The back and front plastics will snap apart fairly easy,
start at a top corner and release along the top, then sides then the bottom
Then just another 12 or so screws and your in.
Don't forget to tighten the 3 screws holding the screen mount to the hinge.
HP seemed to overlook that on quite a few 700 series.
Use a bit of thread lock if you fancy for best results.
HOWEVER::
Now you mention that the graphics has already been under attack perhaps the fault is there.
Was the invertor working before you did what you did or was the backlight doing this before ?
Never seen a dead inverter though.
Hv.
I never knew who HP were until my workshop got filled with faulty equipment. !! I know who Apple are now too.

Help!! Extremely Dim Screen!

Recently, when I turn on my Mac, the screen goes on for maybe 1-2 seconds then goes extremely dim, almost off, I can only just barely see it, is there a way I can fix this, it just happened one night for no apperent reason, any suggestions, Thanks!!!

I'm having a similar problem on my PB G4 15". The screen is incredibly dim (I can faintly make out images but not enough to work on it -- I've had to use another machine for this post).
However, what I don't get is this: if I restart the PB, I get the greeting sign, and my destop picture comes up, and then before my desktop files appear, the screen goes dim.
Previously, I had done the infamous Icelandic "hinge repair" that I read about here, but the epoxy'd screen never really was perfect after that. And I'm using a big binder clip to hold the screen and hinge together. That's worked for over a year.
I can only use A/C power because my machine dies straightaway using its battery.
I hope this isn't too much of a pain to repair, could it be the inverter board as other similar problems that are alike would seem to suggest?
I was hoping not to have to buy another laptop for a year or two or even three, but I console myself with the fact that the new MacBook is "only" US$1000, even if the screen is only 13"
Any insight into the "dim screen problem" would be much appreciated.

Does AppleCare cover my dimming iBook LCD screen?

Hi - Simple question.
Does AppleCare cover my dimming iBook LCD screen? I've had the iBook less than two years, and the screen seems about 50% (maybe a little more) as bright as it was when I bought it.
Note, I also had to have the logic board replaced immediately after purchase, since it blew due to a heat issue. I understand the video module is on the logic board, too. I don't use it more than 1-5 hours, maybe two or three days a week, at a time (I have two other desktop Macs). The real, real problem is, it's my music workstation! Hard to edit notes in Logic Express when-I-can't-see-what-I'm-doing!
Any thoughts or answers? It's getting to be a real bummer not being able to use the iBook as a portable laptop in any brightly lit area.
Really, now. Sorry, I can't make the 10AM meeting, it's too bright in the meeting room with those overhead skylights... unless it's cloudy or raining...
~Robb

It certainly should! My iBook screen is as bright as ever--I got it in March of 2004 and none of the updates had any effect on the brightness. So your iBook screen should not be getting dim from normal wear and tear--there is something definitely wrong. If it's not due to a preference setting or something like that, be sure and take it in for diagnosis and repair before your warranty runs out.
Good luck!

Middle third of screen dark/dim @ startup

I've noticed recently that the middle third of my LCD screen, from top to bottom, seems to be dimmer than the rest of the screen when I first start up my machine or wake it from sleep.
It "warms up" after a few minutes and the screen then looks uniform, but I'm concerned about it getting worse. Any ideas what may be causing this and if it's a serviceable issue? Thanks.

This is not 'normal'! My problem is solved!
I dont know before that something in a System (Preferences, caches, extensions or something else) can cause such problem. But it was the case on my MBP. I only create a new User on my System and the problem is completely gone, no dim part on the screen anymore on wakeup, nothing.
So if anybody else has this problem, try first to create a new User. If the problem not occur anymore it has to do with the system not the hardware.

IBook G4 LCD screen broken

The LCD screen of my iBook G4 was smashed in an accident. The laptop works fine but the screen is broken. What is the best option for replacing the screen? Is there any option in India?
Harisakhee
iBook G4 12.1''

Since accidental damages are not covered under basic AppleCare or the
optional extended service there; you will have to find a reseller who can
do the work and not adversely affect the remaining hardware. So, to say
they should be qualified in repair as any Apple repair would require.
There is an AppleAsia site and perhaps the link I found there can be of
help in narrowing a search for a qualified reseller / repair center not too
far from your location. India is covered under the AppleAsia region, so
that may be a matter of cost and time; depending on distances and the
cost of parts. Some authorized repair centers may have a second parts
computer, (perhaps with different damage?) and if so, you may get a
break -bad pun- on the cost of a display and lid, plus hinge, etc; when
compared to full retail. But I'd expect a first-rate repair if you go to an
authorized Apple reseller with an adjacent repair center; or one they use.
In some localities, the repair still may be routed to Apple; if they have
no one qualified to do them and if parts availability is limited there.
AppleAsia: http://www.asia.apple.com/buy/reseller/ (general finder page)
Apple/India Portable sales/support/service:
http://www.asia.apple.com/buy/reseller/FMPro
There may be other qualified technicians, but to restore an iBookG4
may be a judgement call; and the total costs not under warranty may
be prohibitive in some locations. I wish you well in your quest...
Good luck!

My dv6700 screen is dim, displays correctly on external monitor

HI,
I have a dv6700 laptop that I am having screen problems with. The computer boots just fine, but the lcd is so dim you can barely see that it is on at all. The computer does display correctly on an external monitor. I have even tried switching the lcd out with another known working one and the second one did the same thing. Just to eliminate it, I did try the first lcd with another motherboard, and had no problems with it. I'm pretty sure I have my problem isolated to the motherboard...
Does anyone have any other troubleshooting suggestions before I conceed defeat and give up on this motherboard? I don't know if there are any settings anywhere that might help, something like that. Would the Windows display driver affect the boot up and splash screen? Bios is dark as well. Thanks in advance!

Take a look at this thread and see if it helps. You did look into your power settings on and off the battery?
