Intel Mac :: Screen Goes Black After Startup But Is Still Running?

Jun 19, 2012

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.

Intel Mac :: Screen Stays Black On Startup?

Apr 1, 2012

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.

Intel Mac :: Keeps Repeating Startup Chime - Screen Stays Black

May 5, 2012

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.

PowerPC :: Screen Not Working Fine At Startup / Screen Stays Black On Startup

Apr 5, 2007

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?

PowerPC :: IBook Screen Not Working At Startup / Screen Remains Black

Apr 30, 2007

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!

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...

MacBook Pro :: Getting Black Screen Upon Startup?

Oct 19, 2009

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?

IMac PPC :: G4 PPC Black Screen On Startup?

Mar 19, 2012

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.

MacBook Pro :: Black Screen At Startup?

Jun 25, 2014

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. 

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?

MacBook Pro :: Black Screen At Startup Chime?

Jul 22, 2010

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.

OS X V10.7 Lion :: Black Screen With Pointer On Startup In It?

Mar 8, 2012

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...

MacBook Pro :: Keeps Freezing Up - Shows Black Screen On Startup

Mar 12, 2012

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.

OS X :: System Running Very Slow / Hangs At Gray Screen Ion Startup

Jan 29, 2010

Macbook Air, Rev A. Worked like a charm for 1.5 years.Upgraded to a Rev c SSD and gave the Rev A to the wife.She installed NOTHING.Within a few weeks it started running VERY slow. I'm talking 2 minutes of beach ball per click.I use Disk Utility to check the drive. No problems of any kind.

Rebooting would take -- and I'm not exaggerating -- over an hour. First it would sit with a grey screen for 5 minutes. Then with an apple logo for 10 more. Then with the little spinning circle for 30. Then the desktop background would show up and sit for 20 minutes, etc.

Was gonna upgrade to Snow Leopard so what the heck, backed it all up and installed Snow Leopard. To my surprise, it instaled Snow Leopard on top of the old OS -- it kept all the files around so no need to restore from backup.

Speed problem SOLVED!Then a few weeks later the same problems.This time I check the drive AND run the hardware test. No problems.I ERASED the entire drive. I installed Snow Leopard.All is good for a few weeks.Then the problem came back a 3rd time.

I go to reinstall a 3rd time and Snow Leopard doesn't even acknowledge that there's a hard drive in the machine! And when I look in system profiler it says there's no drive of any sort. Yet it will reboot and run... just VERRRRRYYYY slowly.

I'm ready to replace the drive with a Runcore SSD or some such other device but I want to be sure the problem is the drive and not some other aspect of the hardware (motherboard, RAM, etc.)Anyone ever seen this? Anyone have any ideas as to how to investigate, solve, conquer, save myself from madness??

Intel Mac :: Why Does Screen Go Black

Mar 16, 2012

Ever since I've had my Mac, about three times a day my screen will go completely black after I've moved the cursor very quickly or in a herky-jerky motion. I don't think I'm pressing down on the right or left--it just seems to be some motion.

PowerPC :: Mac G4 Running Leopard Has "Grey Screen" On Startup

Aug 10, 2009

This morning, my G4 refused to start up as usual. Instead, I got a grey screen. Here's what I've tried so far and the results: Action: Started from DVD Install disk for Leopard to try an archive and install. Result: No hard drive was recognized for an install, archive and install, or erase and install, i.e., no drives appeared at all in the "Select a Destination" window, just empty white space. Action: Attempted safe boot (Command + Shift + V) Result: Flashing Globe Action: "Repair Disk" from Disk Utilities after starting from DVD Install disk for Leopard.

Result: Received "First Aid Failed" message. Error message read: "Catalog file entry not found for extent. Volume check failed." I can't even get it to eject the install disk (the "eject" key does nothing and there's no manual eject button for this Power Mac). This is a work computer and not having it functional is pretty hobbling so.

Lately, as of two days ago. My iMac has been freezing and the screen just goes either black or another color that's on the screen.
