Display Not Working on Startup

I left my laptop running last night without power. I woke up this morning to try to turn it on and tho it did start up the display is not turning on. The computer is defintely on. I can adjust volume and the sound plays but display is black. I did turn the brightness all the way down last night when I went to bed... Any tips? Anyone had this problem?

Hi S,
If SU's advice doesn't do the trick: first, plug the power adapter in. Then hold the power button down until the MBP shuts down (5-10 seconds). Wait about a minute, then boot the machine again. If this doesn't work either, try booting into Safe Mode.

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?

Display not working

Hi,
I am using Lenovo G510 Laptop. First I was getting an error of bad signature file which was stopping windows from loading.
I tried to fix it. I changed my BIOS Boot mode from UEFI to Legacy, and then system restarted. After the restart Display is totally black, like the Laptop is powered off. Hard disk light is on, battery power light also turns on when I turn on the laptop. But not showing any display. I've also tried by pulling out the battery and then pressing the power button for 30-60 seconds and then turning laptop on direct power. But it ain't working too.
Please any help in this matter will be highly appreciated.
Regards

Dear sir,
I gave my laptop to an HP authorized service centre in Ernakulum (Vertex techno solutions Bangalore Pvt ltd, Ernakulum) No: 2550, on 04/12/2014 . Same time i registered my laptop complaint in hp customer support. http://h30434.www3.hp.com/t5/Notebook-Hardware/display-not-working/td-p/4760312, informed me that no complaint to MB and GPU . But service centre informed that complaint in motherboard and asked me to change. When I talk them about the your mail and the details that you provided they suddenly respond they can't repair the laptop at their service center, disconnected the phone. I feel very much disappoint about your authorized customer services. In the mean time I kindly request you to take immediate actions regarding these kind of activities also provide a solution to repair my lap top

Thunderbolt display not working on Macbook Pro - previously the display did work

I have upgraded ML but when the MBP tries to restart with the upgrade the MBP does not restart so I susapect the ML upgrade is not complete ? When you refer to 10.8.5 supplemental is this a separate upgrade ? When I connect the Thunderbolt to the MBP the Thunderbolt charges my MBP & I can play music from iTunes via the Thunderbolt. It is only the display that is not working on the Thunderbolt

Hi and welcome to the forum!
Does the keyboard work fine inside the BIOS?
Also try booting from LiveCD of Ubuntu, if issue remains then the keyboard is faulty.
Keep us informed.

External Display not working (descriptive details in post)

Hello
Background:
I have been using a black Macbook (last year's model - before the aluminum ones came out) and connecting it to a VIZIO VW22L HDTV10T (television/monitor) via a mini-DVI to VGA adapter.
This setup always worked, although it was a bit finicky (I'd have to plug it in before closing the display to get in to work in clamshell mode, for example). I get the feeling from reading other forum posts that this is the normal case, though (which so far has been my only real gripe with OS X).
Anyway, back a couple months ago I wondered if this finicky-ness was partially caused by a messed-up preference file, so I decided to try and fix this. In the ensuing tweaking, I somehow caused my Display preferences to disappear.
After much effort trying to fix the problem, I eventually called Apple support, which ultimately recommended that I reinstall OS X. I didn't do that, and continued to work at the problem. I eventually was able to bring it back by going into my Time Machine backups and restoring all the Display preference files (I used old preferences from back when I got the external HD, so I knew they'd be "uncorrupted). However, now I'm having problems with my external display, namely that it is not working.
This problem started early this year, so it might have been caused by the 10.5.5 update, but since I had all these other problems going on, I'm not sure if that was the case.
Problem:
The Macbook doesn't seem to recognize the display, or is having problems routing video to the display, or something.
If I plug the display into the Macbook while it is running normally, the Macbook LCD will flash blue (like it picked up a new display), but them come back to normal. The monitor will go out of sleep mode for a second, but then display a "No signal" message. If I attempt to "Detect Displays" the Macbook screen will either flash blue (as before) or just do nothing.
If I have the display plugged in when I start up the Macbook, everything will proceed as normal until the time the desktop would be displayed. Instead of this, I just see a blue screen (like some generic desktop before any background is applied). The menu bar, the dock, and icons do not show up. However, I can hear various audio cues telling me the computer is running fine except for htis problem (email notifier going off, etc.).
I know the problem is not faulty hardware, because when I boot my Macbook into Windows, everything works perfectly. It therefore follows that it is an OS X problem. I downloaded both Cocktail and Applejack and run various repairs on them (most notable repairing preferences), but nothing has changed.
Any suggestions about how to try fixing this? If there's any technical detail I've missed, let me know.
Thank you in advance to everyone who tries to help.

I have same problem. MacBook Pro (new, 2014) upgraded to Yosemite. Had been running with ViewPoint high-resolution, 27" monitor, HDMI. I tried Thunderbolt connection -- it connected, but it would not allow the external monitor to run at its native resolution (2560x1440). It would only display properly using HDMI. Just 3 days ago after I installed the latest OSx software update, and my external monitor problems started. On startup, my MacBook screen flickers non-stop. I can fix problem eventually (after several tries) by disconnecting the HDMI cable, turning OFF the external monitor power, turning external monitor back ON and then plugging in the HDMI to my MacBook Pro. This is very inconvenient.
I will try using the Thunderbolt cable. When I tried it in the past, it connected, but it wouldn't display the native resolution of my external monitor (which is 2560x1440). Can only get this resolution now with HDMI.

2nd Display not working on iMAC

I have a 2nd display that has recently stopped working with my iMAC - I had issues with the second monitor before I upgraded to 10.9 - then the problems went away ... had a bad storm one night and power flickered on / off. And can't get it to work since. I know the monitor / cord is good because i have an Mac Air and I plug it in and it comes right up and works great. I cleared the system log - unplugged and replugged the monitor in.. i don't see any errors in the system log.. can anyone see what is wrong? I cleared the log and put a marker on each side of the output.. I looks to me to see it - it say display added then right after that display removed..

You can attempt to use Apple Hardware Test, if you do run it in Extended Mode 2-3 times. It's not the most reliable test however if it does locate an error that confirms you have a hardware fault that needs to be fixed. The ONLY alternative is to take it in for service. However IMHO I'd take it in to an Apple Store or AASP anyway, because A) AHT is not that reliable and B) even if it does find something that means you have to take it in.

Laptop Built In Display and External Display not Working

Hi all, I have a HP Envy M6-1158ca, and recently my Built-in display stopped working. I plugged it into an external display via HDMI and it showed no input. It seems as though the laptop is not booting into Windows either, as usually whenever my laptop boots into windows, the fingerprint scanner blinks letting me know I can now sign in using it. I am extremly frustrated with this, and have an unbelieveable amount of stress because this was my only PC. Please respond as soon as possible, it would be much appreciated.
Thanks in advance.
This question was solved.

Yes.. i think thats what might have damaged it...Notebook should always be completely powered off with the battery out and ac adapter disconnected while replacing any internal hardware..
Shouldnt be a BIOS problem....but still you can check this link..
Restoring the BIOS
Note:
If you have HP Support Assistant installed on the computer(The Blue Question Mark) then open it ==> Complete all pending Updates & Tuneups==> Restart and Check. It may solve your problem

FaceTime HD Camera (Display) not working with most applications

The Thunderbolt 27" LED Cinema displays built in camera is not working with most applications. The camera does not work with FaceTime, iChat, Skype and Google Talk. FaceTime says "There is no connected camera", even though there is. Weird thing is it DOES work at http://www.testmycam.com. I can't get it to work with any other flash based apps, just testmycam.com.
My MacBook Pro 17" (late 2011) built in camera works perfectly with everything.
Things I've already tried:
- Shutdown
- Restart
- disconnect/reconnect
- removing power from display
lame, lame, lame. $1k monitor, flippin' webcam doesn't work.

I think I have found the problem. I decided to go page by page through the forums and found this argument when running a Java program through the console:
-Dsun.java2d.noddraw=true
So it would be like:
java -Dsun.java2d.noddraw=true SwingSet2
That works flawlessly, so it has to do with direct draw (So it's either DirectX or my video card drivers which are up to date).

Macbook (Late 2007) External Display Not Working

I have an acer x243hq 1920x1080 external monitor which works with my Xbox 360 (vga cable) and my friends macbook (early 2008) but not my macbook
when plugging the external monitor into my macbook using the minidvi to dvi adapter the macbook screen goes light blue and flashes continuously until i remove the cable, the external monitor is just black (does NOT display "no signal") when the cable is removed the cpu seems to have been running at 100%.
i have tried using my friends macbook hard drive in my macbook and the problem is still there therefore the problem must be hardware related?
i have all current updates
Thanks for any replys on how i can fix this

Have you downloaded the Mac OS X (10.5.4) Combo Update? I posted my problem, very similar to yours, and in researching it I found it at: http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1054comboupdate .html. It might just be what you need!
My problem is that I am running 10.5.7, which I blame for my external display not acting like it did when I was on 10.5.6! One expert at Apple Support told me to erase my HDD, reinstall Tiger, upgrade to Leopard again, but only to 10.5.6! Has anyone any idea as to when 10.5.8 is due out? Is there a Beta?

New Apple ipad air display not working,please help?

Please can anyone offer help? Week old ipad air display has stopped working after app froze and son double tapped home button to shut app down.Thank you in advance for any offers.

If you are editing/testing in the Flash editor, the html end of things is nothing to be concerned about at this stage, and will likely take care of itself when it comes time.
So you run the file in Flash and do not get any error messages? Then place a trace command inside the button's event handler function to see if the button is communicating with it....
function b_1ClickHandler(e:MouseEvent)
trace("button works");
navigateToURL(new URLRequest("http://www.MYURL.com/.html"),"_self");
Also, I'm just noticing you don't have an actual file named in the url, so in case the "not working" is that you can't get the desired page to show, that may be the cause. Normally I would suggest testing url links online rather than in Flash because it's iffy to try to get the web involved with the editor at times.

23" Cinema Display not working. Please help!!!!

I recently purchased a dual 2gHz MacPro Tower and a 23" HD cinema display (both factory refurbished by Apple). Everything worked flawlessly. Then...
I was away from my computer for about a week, during which time both the computer and the monitor were powered down the entire time.
Now my CPU boots fine, and I can hear it responding (when I raise and lower the volume, etc.) but the ACD won't fire up at all. The light on the front isn't blinking or anything, and I'm just wondering if there's anything I can do (I've already reset pram, replugged everything in, restarted several times, etc).
I've also done the ULTRA obvious stuff like brightening my display (which does nothing). I don't know how a less-than-a-month factory refurb that's been off for a week could go kaflooey, but any advice is greatly appreciated.

I'm having a similar problem although it may be USB related. It started with my 2 year old 23" display not waking up when it and the computer (3 month old 15" Mac Book Pro) were asleep overnight. The first two nights this happened I'd restart everything and it'd all be fine. The next couple nights I noticed that if I just unplugged the USB cable from the display into the computer, it would all wake up and function just fine. Today (the 4th day or so, and the day I finally have time to research what the problem might be) the display won't start up at all. There is no indicator light (and never has been in these situations) on the ACD. According to my Display menu bar and my system profiler, my computer definitely recognizes that the monitor is attached (although this was not true the first time the ACD acted up). My mouse also acts as thought the ACD is online... I have now adjusted brightness, and unplugged absolutely everything and replugged it all into a different power source. Still no go... Haven't had a chance to buy a new brick, not really sure that'd work for me... any ideas?
If it were the brick- based on what I've seen on the back of my ACD, it doesn't even look like you can disconnect the cord?
and just a side note... in exploring this problem i noticed that you can choose what the power buttom on the ACD actually controls in the Options menu of the Display System Preferences... is this only for older OS's? because my display preferences has absolutely no Options menu in it...
Thanks.

LCD display not working (blank screen)

One day old 15" G4 (the latest model). No major changes to configuration; only basic software installed (Adium, Messenger, Firefox, Remote Desktop).
The LCD display stopped working during normal operation (web browsing) and I assumed it was a power management issue (I was running on a low battery). I unplugged all devices, plugged it in and rebooted (per instruction manual); same issue.
Since then, I've zapped the PRAM, booted with "R", reset the NVRAM, and reset the PMU. I also tried loading the setup CD with the "Option" to get the hardware check; this may have given me helpful data but I can't see the display so I'm not sure (read: display doesn't work even when booting from CD).
External monitors work fine still. The Mac boots and everything loads perfectly. I can adjust the screen brightness on the LCD using the F1 and F2 keys; the display responds by varying the backlight but it is not rending the GUI; it remains black (or dark gray, really).
I'm experienced with computers but this is my first time working on a Mac, so I'm completely unfamiliar with how to troubleshoot these things. Any help you can provide is greatly appreciated.

Hi

On Screen Display not working on T61P running WXP SP2

This started with an error on 'tponscr.exe' when I hit a volume button. I reinstalled the Thinkvantage Hotkeys from the Lenovo site and I no longer get the 'tponscr.exe' error but the on screen display doesn't work (Volume does change tho). The Fn keys also do not work as well. System update also did not correct. Any help or suggestions would be appreciated. Thanks,
M/T 6457-C34 T61p WXP-SP2

I've had no luck with the latest HotKey drivers on my T61. I revereted to the driver version that came with the T61 and things seem to be working. In case you want that version, I've posted it to

3rd display not working with Yosemite. Was fine with Mountain Lion. Any suggestions?

I use my Imac as a digital aidio workstation with 3 displays. Never updated to Yosemite due to issues with the DAW manufacturer software. Now that the issues were resolved, I said what the **** and I updated to Yosemite. Now my 3rd display does not work at all and I am not a happy camper. Gives credence to if it ain't broke don't fix it. Thanks all.

Hello mrtessitor,
I'm sorry to hear you are having these issues with your iMac after a recent update to Yosemite; I know how frustrating that can be. If you are having issues with one of your external displays that was working previously, you may find the information and troubleshooting steps outlined in the following articles helpful:
