Mac Pro :: Black Screen Display On Startup
Sep 28, 2010
I 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...

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?

On startup, I get the Apple and Spinner for about a minute, then the display goes black. I've tried starting from install disk(holding C on startup), resetting my PRAM and starting in safe mode. None has worked.

I 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 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

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!

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.

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.

The 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).

I 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?

I have a core i7 MBP with the high res display, and when the display is showing black, a horizontal green line appears on the screen. It is only visible when the screen is showing black or another very very dark color, and the line is not visible with the screen off. It isnt something on the screen, as rubbing it does not affect it at all. I cannot post a screenshot of it, because it does not appear in the screenshot (it does on my screen, because the line is there physically, but on other monitors it is not visible).

So I've got my MBP that I've had for about 4 months, the thing is. It just recently started to have screen flickering issues. I'll be sitting doing w/e as usual and all of a sudden the display goes dark, almost black, for a second, then comes back up again. I have yet to find any trend in when this is happening, but it is definitely happening on battery as well as plugged in, but it seems to be getting worse.any one have any idea what this could be, something I can fix on my own, or should I take it in?

For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.

I have a MacBook Pro (13'', Early 2011) & iMac (21.5", Mid 2011) using a Thunderbolt Cable to Target Display. Everything was working find and I could Command F2 to Target Display as expected.However, about a week about this stopped working. Now when I try to Target Display the iMac goes to a Black screen (like it's switching to Target Display) and the MacBook Pro does nothing. The iMac will be at the Black screen until I Command F2 again (or disconnect the Thunderbolt Cable), then the iMac goes back to the normal display. I have tried another Thunderbolt cable with no luck. I have perform all software updates on both machines (now both running 10.7.3) and fixed Disk Permissions. I have also found that restarting my MacBook Pro allows this to function as excepected (Command F2, Blue Flashing Screen, Target Display on the iMac). However, this is not an ideal situation since having to restart my computer is time consuming. Â

I have a early 2011 MacBook Pro 13" running the latest version of Lion. I have been using my MacBook with an external monitor since I brought it in 2011 and have had no problems with connecting it to my external monitor. Connected via mini display port DVI adapter and a DVI cable to a Philips monitor.
Two days ago when I plugged the MacBook back in to the monitor I connected and but now only displays a black screen, I can move the mouse off the MacBook screen and over to the external monitor and back but it is not displayed on the monitor. I have tried connecting other devices to the monitor and they work fine.

Macbook pro 2014 only had it for about 2 months but recently about three weeks ago the display has been flicking to a black screen but has gradually been increasing and it now happens every two minutes - just randomly goes black for about 5 or 10 seconds and sometimes goes back to home screen but sometimes goes to log in screen, It interferes with me trying to do my work when this happens so frequently
