My 2008 Mac Pro display remains black after start up. It is plugged in properly and the light comes on, but the screen stays black. It first started doing this about a week ago, but after a manual restart or two, it would start up properly with the display working. Today the display has remained black every time I've tried to start up.Â
View 3 RepliesI was browsing the internet, not doing anything major, put the computer to sleep, came back 10 minutes later... black screen. I messed with it for an hour or so and determined that the video card went bad (I'm guessing. It's a mid 2007 macbook pro with the nvidia geforce 8600m. My secondary monitor remains black as well). In the midst of totally freaking out, I decided to activate the voiceover utility, enable screen sharing (after figuring out a slew of keyboard commands I didn't know about), and logged in from my girlfriends computer.
I immediately closed all the windows and applications that I had inadvertently opened during the blind wtf session, and opened up system profiler to see if it is recognizing a video card. Well, it is! It's listing the video card as a GMA x3100! Is there a secondary card in there? Cause if there is, it's not working either. Or is that just a default they would put in if it doesn't recognize a video card? Doesn't seem likely. Or, because I'm using screen sharing, is it picking up my girlfriends card? It's not, because she's using a GMA 950. Maybe it's splitting the difference?
After moving I setup the Mini, but got nothing from the monitor. Reset PRAM & PMU, nothing. CPU chimes, etc.work, but the only thing I get from the monitor is a yellow square with a brief message indicating there's no signal.
It's a Mini, 2 MB RAM, Core 2, OSX10.5.x, it's less than a year old. The CPU appears to be OK. Monitor is getting power.
I'm trying to connect my rMBP13 (OS X 10.9.3) received a couple of weeks ago to my desk display (LG Flatron W2486L) through apple's DVI-mini display port adapter.
Here is the results:
The MBP freezes a couple of seconds (I guess normal) after plugging in the mini display connector in one of the thunderbolt ports, but nothing happen on the external display (no signal).
The MBP sees the display: from "system preferences>displays" I see the MBP sees the external display and recognises the model "W2486"; but it seems to me that the display doesn't see the MBP...Â
I've tried to restart the MBP, but with the same result.Â
(I've ben using the display through the DVI port with my old PC, so it works).Â
My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!

View 8 Replies View RelatedI have a Mac Pro (Early 2008) running on 10.5.8 OSX with apple 20" display and 16G RAM.
Initially started with my MACPRO not waking up from sleep and has to force the shut down with power button. Finally realised it was due to my Epson scanner connected via USB...
The main issues now is with the display, black screen on startup. I can still control the volume and disk eject/close, just no display. Force shut down with power button numerous time but futile. Finally solved it with SMC reset.
it becomes an on and off issues... and continuously I solved it with SMC reset.... sometimes needed 2 or 3 resets to get it to work,and finally for the past few days... SMC reset can't solve it either... no display on startup, and same thing I can control the volume and disk eject/close. Have tried my monitor on other mac and it worked fine.
Now this is strange. if I let the mac cool off totally,after a SMC reset. the display will comes up fine...
I slept my MacBook Pro last night and can't wake it? I have rebooted and no bing sound is made. The screen remains black. The volumn keys blip. It is as if it is still locked in sleep mode!

I have a 2009-2010 27inch iMac with OSX and software fully updated.My Mac started shutting down or going into deep sleep when left on.I've tried rebooting, power long hold, checking cords etc.I've attempted the 5 second hold after disconnecting the power cord, plugging back in and start no luck.I hear a very small click inside when I long hold, sometimes a very faint spinning sound but nothing else.The fan came on once after a start attempt but nothing else happened. I can't seem to safe start because the screen remains black.

I have a problem: when I restart my Early 2008 MacBook Pro there is no "chime" and the screen remains black. The keyboard doesn't light up or respond to any input, and worse still, the "lid button" light on the front of the notebook remains illuminated, it doesn't blink, it just stays on, shining in my face. I loaded a CD into the optical drive to see if I could use the keyboard to eject it, but this test failed. Now, when I turn on my MBP, I hear the optical drive spinning and the quiet whirr of the fan inside.
I looked on Apple's support website about what to do when a Mac refuses to boot. I tried all of the methods they listed, but since my Mac doesn't respond to keyboard input, all of the techniques failed. Having exhausted everything I could think of, I decided to post here hoping someone could suggest something. I was just on the verge of completing my portfolio website and I would like to salvage my data at least.
When I open my macbook, the screen remains black (as though it's in sleep mode). Adjusting the brightness always fixes this problem, but this is a temporary fix. The brightness is not at zero when I adjust it after opening, often I need to dim the screen to reactivate it.
This problem is not: related to *clamshell mode*related to unintentionally dimming the screen. related to any of the settings in the Energy Saving panel in system preferences
Extra info: The computer seems as though it doesn't actually enter sleep mode when I close the computer.I don't think there are any processes running that would prevent sleep mode. I really just want the computer to go to sleep properly when I close the screen and more importantly, that it wake-up when opened, or at least when a button is pushed aside from the brightness buttons.

A few days ago I began having trouble with my Mac Pro (Dual Proc. 2.8 Ghtz, 2 GB RAM, DVI display, OS 10.5) It would not wake up after going to sleep. I did the PRAM and SMC resetting thing, and I thought it had worked, but now just two days later, the computer does turn (the bell rings a la Wall-E and everything) but the display remains blank. I plugged the display into a MacBook pro and it worked fine, so I'm guessing the problem is the DVI port. 3 questions arise:
Does anyone know of a sure-fire way to find out if the DVI ports ARE the problem? I did hook up the computer to a Power Mac (G4 running OS 10.4.11) in transfer mode, and the HD did load, I also performed the first aid thing on it and everything came back positive.
Does anyone know if changing the DVI ports is simple enough to do, or should I definitely leave to a professional? (I am fairly familiar with putting stuff in and out of it)
Should I buy the DVI card directly from Mac or can I get by with a less expensive brand?
Okay, so I am running OSX and Vista on Bootcamp. I have noticed that when I use Windows or just even restart OSX that my date and time changes. Today it changed to March 1, 2000. I am curious as to why this happens. My time zone is fine. I think it has something to do with the Vista configuration.
View 4 Replies View RelatedI came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

My brother's iBook G4 (I think it's a 2003 model) has a problem with the screen. When the computer is turned on, the screen stays black, although the backlight is on (the apple glows). Sometimes, on start up, the screen works normally for a random amount of time before going fuzzy and then black again.
Any ideas on how to fix this? Is it likely to be a problem with the hardware in the actual computer, or just the screen? Or is it a software thing?
Just got my macpro few days ago and black screen shows at start up, sound and keyboard light will turn on Except for the screen. I dont know what to do!

Last night I was using my computer all fine. However this morning I turn it up, the white light where you push to open the lid, is on without flashing, and there is a black screen.
Please note that I have not installed any new hardware devices i.e. hard drive, ram, etc.
I tried to push the power button for like 10 seconds straight when I turned on to see if that would fix the problem but no. I can hear the hard drive starting up when I push the power button but black screen.
Could this perhaps be one of those faulty 8800 M GT nvidia gfx?
But I'm scared to take it to Apple because earlier this year, I took it apart and redid the thermal pasting and I kind of have screw drive marks on my keyboard aluminum part... It's like so obvious I opened it before. But, my 1 year coverage is already over so hope that doesn't eliminate me from getting that nvidia service in the case that it is the gfx card hardware problem?
I have been limping along for quite some time with a recurring problem with my PPC Flat Panel iMac G4.Sometimes when starting up I would get a black screen. The unit chimes at startup but the screen would stay black.I found that I was able to fix (temporary) the problem by removing the bottom plate and pushing the reset button under the base.(After shutting down and unplugging the unit.) after the startup chime, the screen turned gray with a folder icon in the center with a blinking question mark.After shutting down and restarting, this happened again 3 times.On the 4th shutdown/startup it went back to the black screen.Repeated shutdown/restarts have no effect.Shutting down, unplugging the unit and pushing the reset button is also having no effect.I hear the startup chime every time. Black screen every time as well now.Â

every morning I turn on my new Macbook Pro the screen stays black. When I move close to the screen I can see the password entering box far away, when I then type it it is booting into Mac OS X but the screen is still off. After some time, the screen blinks a couple of times and then the screen is displayed as it should and I can work all day.Â
I have resetted PRAM and called Apple Care. They made me reinstall OS X mavericks.Can it have something to do with the fact I have FileVault enabled on the disk?
I just replaced my LCD. It was working fine, but now just stopped working. It's a mid-2009 A1286 15in Macbook Pro.
The computer itself works fine and I tested it using an external monitor. I can FAINTLY make out the display on the screen, so I'm guessing it is a backlight issue? Don't mid-2009 don't have display inverters?
I also tried resetting the pram and SMC.
I have had to do hard restarts in Lion when it satrts up with a black scren and the mouse pointer and nothing else. It happened most recently today with a scheduled wake up from being asleep. The other day it restarted with the pointer acting as a painting program and actually colored the path of the cursor until it eventually painted in enough of the login window to enter my password and log in... I have reinstalled the os from the App store and it still acts strange some times...

This 5 year old iMac makes the seek optical drive sound when switched on, but does not chime, but I can hear the hard drive going afterwards.
The screen just stays black, not a flicker.
The problem is that it is located in a small pretty isolated town in NE Brazil, I will be going back out there later in the summer so if anyone has any helpful ideas it would be most welcome. Fortunately we have a full CCC clone of the hard drive and a working MBP so we haven't lost anything, but it would be very good to have it working again.
Does it have a socket for an external monitor, I really cannot remember, as I have not seen it since November, I know the old round iMacs had one.
The nearest Mac store is probably in Rio or Sao Paulo which are a good day travelling by car and plane so there is no chance of getting it there.

I replaced my hard drvie in my A1208 iMac yesterday, and didn't have the OS disc or a keyboard. After installing the HD, I booted the computer to make sure everything was working. I got the "?" screen, and everything seemend to be working just fine. So today, I picked up a keyboard from the Apple store and dug out the disc After I got back home, I booted the computer to install the OS, and the screen went black a few seconds after the chime and grey screen, but was still running. (I could hear the fan and disc spinning) I've tried to restart, but i'm still having the same problem. I've tried to research other issues, but haven't found anything comparable.

As the title states. I am looking for an external display that matches the display on my black MacBook. I want one with the same gloss finish as my MacBook, this way I can calibrate both screens to look the same. That way when I switch screens it doesn't look different.
Anyone know of a screen that looks identical to the (previous generation) MacBook? I was thinking of getting a Samsung T240 but it has a different finish. How are ASUS screens? Any screens out there that have the same gloss finish?
Recently my Mac has been extremely unstable. It keeps freezing up and hanging for no reason. Initially a 3 beep would sound off, I ran some tests like the apple hardware one and realised that one of the rams was bad. I bought 2 new sticks of ram and replaced it. Following which, the mac still freezes up and a 3 beep alarm sounded off again.
Currently, I'm trying to turn it on, no 3 beep signal is sounding off but the Mac either keeps freezing and showing a highly pixelated screen or a black screen surfaces. There is some sound coming off from the laptop as well. Each time I switch on the system, it just shows a black screen with no display.
The Mac is a 15'' 2.66 MHz i7 which was manufactured in the mid 2010s.
The 2 new sticks of ram are Strontium 1066Mhz 4Gb x 2 sticks.
In the initial stages: kernel panics were common as well.

When I start up my macbook pro white and black lines appear for the startup screen in bunches. After that the screen is black but the keyboard is lit up and you can still hear the sounds of turning up the volume and music can still play.Â
View 1 Replies View RelatedThe latest iMac model. When I click on the power button: I can hear the Hard disk and the DVD drive spin up. The screen stays black. The startup sounds plays half way through the first time, like its being cut off. After the first startup chime has been cut, the chime keeps playing in a loop. The computer doesn't come any further than that.
I have tried: Unplugging all peripherals, with the same result.
SMC reset: Unplug power cord and hold power button for 5 sec. PRAM reset...
It seems like the computer does not even get to boot and ignores all keyboard input. I also tried booting from the DVD drive with the installation disk. But I can't get any further than the repeating startup chimes.
I cant seem to make it shut down completely or re-start, it seems to be in sleep mode and wont wake up. When I try and restart it makes a sound like its trying to eject a disc (there is nothing in the cd drive).
