Display goes weird since OS 10.5.6

Everytime I start or restart my display dims to less than 1/3 of its power. I can bring it up to full power with the keyboard and than it works bright again. Any one any idea what's going on?? Thank you.

Allan, thank you very much. That was the problem. Everything is fine now. Thanks to you. Yes I was always sitting in a very dark room when this happened. Now if I only could find some one to solve my main problem. When I run the DiskWarrior repair program for Rebuilding the Directory, something that worked for me for over 2 years now, the DiskWarrior program kind of crashes at "Rebuilding Directory Step 8 " and asks me to shut my computer down. Haven't been able to solve this now in more than 24 hrs. of trying. Thanks again for your help and all the best. Sincerely Volker

Cinema display goes black upon resolution change in Windows XP

Greetings
Earlier today, I updated my ATI X1600 Radeon to the latest Windows Catalyst drivers and to the Catalyst Control Center from ATI. Even since, whenever a Windows application (games, in this case) tries to change the resolution on my external Apple Cinema Display (designated as the main monitor in the ATI Catalyst Control Center, with the MacBook Pro display disabled), the display goes black, and the monitor power lamp starts to flash.
If I unplug the external Cinema Display from my MacBook Pro, my MacBook Pro display activates, and displays whatever it is I was trying to launch, so the problems is somehow related to the Cinema Display, even if the new drivers are causing it.
This happens regardless of my Catalyst Control Center settings, such as scaling the lower resolution to fit the screen, or keeping it the original size, with black borders around. The problem does not occur when I launch games using 1600 x 1024, the Cinema Display's native resolution.
Any ideas what might be causing it, and how to resolve it?

Update on my situation: when I tried to change the resolution manually in Windows, I encountered the same problem. Now, whenever I connect the Cinema Display to my MacBook Pro, the same thing occurs: the screen goes black, and the power lamp starts flashing, even though I've changed back to 1600 x 1024.

Caller display not worked since June 2014

On 26/06/14 I reported a fault (VOL-**********) that the caller display function had stopped working following a thunderstorm in the area. According to the fault status this fault is showing as being corrected and closed on 02/07/14 when in fact the fault still exists. I tested the line using the BT test socket with a new BT2000 phone and this displayed ‘incoming call’ therefore my internal wiring is not part of the problem. I have also dialled the test code *#234# to check if the caller display service is available and confirmed that it is. I then tested the new BT2000 phone on the neighbour’s telephone line and this showed the caller ID for incoming calls, as did my other telephone as well; therefore none of the telephone handsets are at fault. Three times BT have informed me that the fault has been fixed and yet I still have no caller display. Reading through the forums it would appear that other people have encountered similar issues and that the problem is at the exchange, “An Openreach engineer discovered that the RS232 burst transferring the CLI number up the line was too weak and he then went down to the exchange to investigate. He then discovered that the fault lay in the ADSL device which lies between the analogue exchange equipment and the outgoing line”.
I’m surprised to see that BT are taking so long to trace a fault in their system last raised 5/8/2014 (VOL012-**********) and that they haven’t sent an engineer to the property or to the exchange to check the problem.
My patience is wearing thin over this problem with my Caller Display not working as it started in mid June. I’m also becoming less enthusiastic about BT and find it harder to recommend them to others.
My last message from BT, tells me that it should be back to normal on the 8 August. However, it is still not working. Their message that my phone should be back to normal now and if it isn’t report this to BT, is ridiculous. If an engineer had investigated what was causing the fault and found it, then he would have fixed it. However, either an engineer has not investigated the fault or BT is not competent in fixing their own service faults and makes these statements with crossed fingers?

An engineer called yesterday and told me that he had been asked to test the line for a voice fault not a Caller Display fault. However, his testing revealed there is no line fault, CLI signal is strong and he was happy that the new BT2000 phone (bought after the lightning strike) is working properly. (This phone had also been tested on a neighbour’s phone line where it displayed the callers number). He also found that this same BT2000 phone on my line was not displaying the Caller’s number (CLI), but couldn’t offer any reason why.
I conjectured with him that these tests must bring the problem down to a corrupted CLI signal which does not allow the phone to understand the phone number being sent.
When the lightning struck the phone line back in June, it blew the telephone connection in the back of the Sky Box with a flash and bang (telephone cable now removed from the Sky box). It shorted the Openreach Faceplate (now replaced) so that the phones and broadband stopped working and it caused the phone to light up and react as it does when a call comes through.
Now isn’t it possible that the lightning also travelled along the copper wire to the green cabinet just outside the house and damaged something there which is corrupting the CLI signal, but which does not not show up when the voice line is tested? If not, then there must be a problem further back in the infrastructure, possibly in the Exchange, that is causing a corrupted signal to be sent to my phone?
He told me that another team would have to investigate the Caller Display fault as he was instructed to look into a voice issue and as a field engineer he was not able to investigate any problem that might be in the Exchange. I don’t know whether this Exchange Team would be able to investigate a problem in the Cabinet if nothing is found in the Exchange or can that only be done by a field engineer? He told me to contact BT again as he’d done all that he had been instructed to do and they would have to instigate a fault team to further investigate the problem.
When all this is considered we have the basic problem that BT are unable to provide me with a Privacy and Caller Display Service that I have been paying for, because of a fault in their infrastructure. How much longer is it going to take before they correct the problem that’s been going on since June 2014?

My display goes off when Battery being charged on Acer E5-511 after upgrading to Windows 10

I upgraded my window 8.1 to Window 10 on Acer E5-511 machine yesterday. I notice that when I switch on power to charge its battery, a beep sounds and display goes off. when power is again switched off the display comes back with a beep again. However, when the machine battery is allowed to charge for some time, either it goes to hibernation mode or stops working since display does not come back even after switching off the power supply. This peculiar problem did not existed when I had used this Notebook with windows 8.1 for past eight months. Can any one help me to solve this problem as i am being forced to charge the battery only when Notebook is not powered on.

A BIOS update fixed Grey Bat's (a.k.a. Myotis grisescens) problem. http://community.acer.com/t5/Windows-10/Restart-problems-with-Acer-E5-511-P8C8-laptop/m-p/370322#M24 http://us.acer.com/ac/en/US/content/drivers Edit: Acer also said that "Your system may require additional software, firmware, and/or a BIOS update to install and run Windows 10." http://us.acer.com/ac/en/US/content/windows10-eligible-models

Display goes black randomly

I purchased the notebook barely 16 days ago, and after a few days I noticed that the display goes black for a second or two randomly i.e it doesn't happen while holding the notebook in any certain way or something. The dislay goes black anywhere while playing games, music, videos or simply anytime. Also now there's some flickering in the lower part of the display. It happens with no approx time gap. I asked HP's Chat Support to help me out of this, they tried to uninstall and have a clean install of display drivers, that didnt work.Then they said they'll assign the nearest Physical service centre for an onsite visit and that some one will contact me, but waiting since almost 4-5 days this didnt happen. For the past two days I regularly ask HP's Support team about the promised visit but they keep on saying that today you'll recieve a call positively. The problem has escalated to such an extent that it interferes with my studies, work and daily use. This all has cost me alot of time and money and it's all due to your faulty product and carelessness. I would like you to help me in this regard, asap, if it is at all possible for you !! Edit : Before you ask, everything's updated to it's latest version. and I don't have an external Monitor.

Sattelite 1800-752S - the display goes off

Hi everybody.
I have a satellite 1800-752S.
SInce a ew months ithas a wierd problem: the display goes off. If i press and quickly release the lid button it comes back on, but after that goes off again. SOmetimes ot goes off immediately, sometimes after a few minutes, or even hours. SOmetimes it keeps being on when I am running from battery, and annoys me on AC, sometimes the versus. It works quite well, after I turn it to standby or hibernate a few times, and after a restart it annoys me.I have updated its BIOS to the lates from this site, that wouldn't help. I assume it is a hardware problem, because it is the same problem under Linux, and I have tried to install different verisons of drivers and Windows (not only the one from the Recovery CD). Did anyone have the same problem before. Any help will be appreciated.
Thanks a lot
Roman

Hi,
I think you are right, it's a hardware problem. But to be sure, try to connect an external monitor. If it works without problems while the notebooks display goes off, then it must be a hardware fault.
I assume it's a problem with the FL-inverter. You have to give your mashine to a Toshiba service partner for repair.
Bye

Display going off

My display goes off after starting the pc, sometimes after 5 mins and sometimes at the BIOS setup, and even during Windows startup repair. RAM and PSU are fine as I am using them on a different motherboard and they are working fine. Also when the display goes off, sound doesn't go off immediately, I can hear background music and then there is some noise and sound also goes off, HDD led stops blinking afterwards. Sometimes, HDD goes off along with display. So is the culprit graphics card or motherboard or something else( The other motherboard which I tried, (Nvidia 630i) had onboard VGA and it worked fine)
My specifications:
Motherboard: MSI P45 Neo-F (601-7519-010) no OC
RAM: 2X2GB Corsair DDR2
HDD: WD Caviar Green WS6400AACS, 640GB
PSU: Corsair VX450, 450W
GFX Card: ATI Radeon 4850, 512MB DDR3
Operating System: Windows 7
Processor: Intel E6750, 2.66Ghz

It is highly recommended to use identical modules. Using non-identical but similar modules either works properly or it doesn't. The answer depends highly on what specific memory combination is going to be used on what system. So, basically, if you can avoid mixed configurations, avoid them. If you already have the modules there in front of you, go ahead and simply test it. There is no risk of damaging anthing (well, at least not in general).

but since pc is booting properly, motherboard should be fine right?
Probably --> which means that I personally believe that a problem with the video card is more likely to be the cause. That is why it makes a lot of sense to start testing on that front first. However, the mainboard is not necessarely out of the equation. It is not very likely, but still not totally impossible that the mainboard is the cause for your problem.

MacBook Pro retina display goes black while outputting video through HDMI to external monitor??

I frequently connect my MacBook Pro to my 42inch Panasonic TV to watch movies/videos. I use VLC media player for all my playback. The problem I'm running into is that when I put VLC media player into fullscreen mode on my external display, my retina display goes black (I can still see the finder bar at the top and when I mouse down the dock appears but the rest of the display shows all black. If I click on Safari it will open but I can't see it on my MacBook display unless I take the external display out of fullscreen mode.
I would still like to be able to do things on my MacBook while video is playing. I've played around with the display settings but they're pretty limited and I can't figure out how to get it to work the way I'd like. I've seen people having up to 3 or 4 displays hooked up, I'm just trying to hookup one. I would consider this a severe limitation of OS X if I'm not able to separately manage the displays. Hopefully there is a setting or something I'm just not seeing. Thanks.

Yeah, fullscreen mode still doesn't play nice with multiple monitors. The common workaround is to stretch the window out to the edges of the screen instead of using actual fullscreen mode.

Hello QuinnDev,
Thank you for posting in the Apple Support Communities. It sounds like you are trying to use your MacBook Pro with a Thunderbolt Display in closed clamshell mode (MacBook Pro closed), but sometimes the display doesn't stay on. I found an article that talks about closed clamshell mode. You would have to fulfill the following requirements to use your display this way:
Requirements for closed display mode:
Power adapter
External keyboard, mouse, or trackpad
External display
You can find all the steps and the full article here:

Mac mini 2011 display going black

I just got my new core i7 + SSD 2011 Mac mini. I noticed during initialization of Lion and during a reinstall of Lion that my screen would flash to black for a second or two. A few days after installing Lion I still get this random flash a black a few times throughout my sessions. It usually only does it 2 or three times withing 10 minutes of turning on the the computer, then it seems to be fine. One time it flashed a few times and then the display went all distorted and pixelated. To fix it I ended up having to disconnect my 24" Cinema display and reconnect it. This whole display issue is really annoying.
I found this so I hope Apple is working to fix this issue:
https://discussions.apple.com/message/15843631#15843631

Shutdown the Mini, turn off the display, disconnect and reconnect all of your power and display connections ensuring that they are fully seated and snug.
It could also just be that the display going to sleep and then rewaking.
1. Go to: System Preference / Energy Saver and check to see if your Display Sleep slider didn't maybe get set to under 3 minutes.
2. Go to: System Preferences / Exposé & Spaces / Exposé and see if there isn't a Hot Corner set to "Put Display to Sleep" that you pointer might be going to.

Hi,
I work for Dr Pod, an iPod repair company. This sounds to be that the hard drive is dying in the iPod. As it is an older iPod it is out of its one year warranty, the iPod won't be repaired for free by Apple, and you'd need to consider wether it'd be better to have the iPod repaired by an iPod repair company such as my own, or to purchase a new one from Apple.
If you did choose to purchase a new iPod from Apple, then they do provide 10% off the cost of a new iPod if you exchange in your old one. I'm not sure if this applies to faulty ones though (I have heard of some people being turned away for having a faulty device).
Hope this helps,

Toshiba LCD 46G310U display goes dark

I have a Toshiba 46" LCD model: 46G310U that when first plugged up has a perfect picture on all inputs. However after a few seconds to a few minutes the display goes dark with a horizontal line across the screen about half way down. The horizontal line will fade out after 25-30 seconds leaving the screen dark(back lights still works). I have replaced the inverter board, the T-Con Board, replaced most of the larger capacitors on the power board, I have even replaced the cables that connects the T-Con board to the main board. If I unplug the tv and leave it unplugged for several minutes when I turn the tv back on, the picture is back and purfect for the first few seconds or up to a couple of minutes, then the screen goes black again. Please any help would be apprecieated. Thanks.

You may want to find an authorized service provide to repair the TV.

Run iPhoto slideshow on 2nd display without 1st display going black?

Hi there,
I can't seem to find a clear answer on this one. I have just connected a 2nd display to my mac mini via the thunderbolt connection. When I put iPhoto 11 onto the 2nd display desktop and run a slideshow it plays on the 2nd screen but my 1st screen goes black, which isnt ideal as I want to be able to carry on working on my 1st screen.
Is iPhoto 11 able to run a slideshow on a 2nd display without 1st display going black? If not, is there a way around this by using other software?
I have the 2nd display set up in extended mode not mirror.
I am running OSX 10.9.2.
Many thanks,
Andy.

Is iPhoto 11 able to run a slideshow on a 2nd display without 1st display going black?
No.
There may well be, but it's not possible with Aperture either.
Alternatives to iPhoto's slideshow include:
iMovie is on every Mac sold.
Others, in order of price:
PhotoPresenter $29
PhotoToMovie $49.95
PulpMotion $129
FotoMagico $29 (Home version) ($149 Pro version, which includes PhotoPresenter)
Final Cut Pro X $299
It's difficult to compare these apps. They have differences in capability - some are driven off templates. some aren't. Some have a wider variety of transitions. Others will have excellent audio controls. It's worth checking them out to see what meets your needs. However, there is no doubt that Final Cut Pro X is the most capable app of them all. You get what you pay for.
