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.
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 have a Macbook 2009 that wont turn on. When you press the power key you hear the normal boot chime but no picture appears.Â
The laptop was given to me without any hard drive, so I installed a blank 250GB HDD. The HDD has no OS on it, and I am not sure how it is currently formatted as it is new.Â
Even when I use an external screen and regardless of whether a HDD is present the macbook does not show any sign of life on the screen or external screen but still chimes.Â
I know it would be a good idea to boot with restore discs etc, but even if no OS is present surely the screen should still come on and display the gray and apple logo? I did all the resets and holding button configurations on startup, such as reset PRAM.Â

I have a macbook pro retina display mid 2012 model. When i boot up i hear a chime but screen is black. I wait a few min to allow it to finish booting up with a black screen. I close the mac book for a few minutes to let it fall asleep. When i open it , screen works and im on login screen.

I've got a nasty issue with my 13-mo. old MacBook.
I'm pretty sure it's a dead logic board and possibly a dead hard drive, which I really, really, really hope not as I don't have backups of everything on the drive. I just upgraded to Leopard this past week and did a clean install so not all of my stuff is setup yet.
Power adapter and battery are inserted. All 3rd party peripherals and RAM have been removed.
MacBook does not chime at boot. The screen flickers, but stays black. If I hold down the power button then try to let it boot the light on the front right flashes constantly (like when it's sleeping but a faster pace), like a turn signal on a car. I can hear the cd-rom drive whining but everything else is dead silent.
I've done everything here with the exception of calling Apple.[URL]
I've also tried FW Target Disk Mode, but the MacBook drive does not show up.
I've done everything I can think of and I'm out of ideas at this point.
Additionally, there's a cd-rom (Tiger Restore CD) stuck in the drive. Holding down the mouse button during restart does not eject this CD. Where is the force eject button (I see no pinhole)?
I have business documents, emails, etc. that I HAVE TO get off this hard drive. How can I do it? I don't have a 2.5" drive enclosure but if that will solve the situation I will pick one up asap.
My macbook air 2013 doesn't start.black screen. It gives starting chime but then nothing.

OS X Yosemite (10.10.1)
So my girl friend was using my IBook G3 and shut it down normally she says. We then went to turn it on and we will hear the chime but then it will get stuck on that first gray screen, nothing else comes up, no spinning no nothing. Hard drive is not making any different noise, I just don't know whats up.

It wont boot off of the system dvd and I even tried installing an HD that has a good version of the the OS on it. I also tried booting from the DVD with no installed drives to rule out one of the internal drives doing someothing funky. Nothing happens at all, the HD or DVD will spin for a moment and then all is dead.

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?

After an update(I think) I can no longer get into my computer. When turned on I get the apple logo then a grey screen that turns to black but the curser is active . Then there is no more progress to the startup screen

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?
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?
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.

MacBook Pro (15-inch Mid 2010), Mac OS X (10.6.8)
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).

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!

I have a mid-07 Santa Rosa MBP. When I turn it on, nothing comes on the screen (not even backlight), but I'll hear the startup chime and 2 seconds later, it reboots and does the same thing. Here is what I have tried:
1. Reset SMU
2. Reset PRAM
3. Replacing HD
4. Replacing PRAM/CMOS battery
5. Tried booting off DVD (but it reboots too fast after the chime)
Hi guys, I have a 2.26ghz Macbook and when i start it up the chime keeps repeating over and over again until i get sick of it and hold the power button to force shut it down, sometimes it will start up fine after that and boot right up and sometimes it keeps repeating again, then i just leave it for a few hours and try again and it will usually work. Also over the last day or so i've been getting a mixture of the repeating chime and the blank white screen with no apple logo and grey spiral. Other than this problem the computer is running flawlessly, does this sound like a hardware or software problem?
I've already tried reseting the PRAM and SMC, I've ran the hardware test which came up clean, checked the drive with disk utility and eventually reformatted the HDD and reinstalled Mac OSX but still no change. I'm not running any extraordinary software just google chrome, Skype etc. so that shouldn't have any thing to do with it.
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!
Info:MacBook Pro (15-inch Late 2011)
however today suddenly the superdrive decided to make a 1-2 second 'seeking' sound at *every* startup. there is no dvd inserted nor have i used it even once in this week. it does this at the grey apple screen at the same time the apple "chime" sounds.
i am pretty sure it didn't to this up until today, i am not particularly concerned but why would it start doing this after a week on its own?
I installed Stuffit Deluxe 10 on my new MBP and ever since I have installed it every time I startup or reboot my MBP the startup chime sounds muffled. All the other sounds are fine though.
View 1 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 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

Here's a bit of a strange one, noticed over the last couple of days that the start up chime was getting quieter, then today no sound what so ever when turning it on.
Now from my understanding of it, the chime is a bit like a POST beep on a PC? Hear it once and every thing's fine? Otherwise the MBP is booting up fine, dual booting it and have sound in OS X and Win 7?!
Suspect I may have a HDD issue, as had to run chkdsk /f /r the other day and had to stop it after 12 hours as it was still on stage 4 of 5 @ 18%, and it seems to be running slower, also the HDD is becoming more vocal.
I'm going to run a full AHT on the unit, was just wondering if anyone else has come across something like this before?
When I start my Macbook Pro (mid 2009 15") I get the familiar audio chime. However, when it finishes startup and I get to my desktop, I have no audio, and the audio icon up top is grayed out. The audio output jack works fine. I can use speakers and headphones. I've tried the solution of wiggling around a headphone plug in the jack, as well as doing the same with a toothpick. I've also reset the PRAM. For some reason, the problem persists. When I open sound settings in preferences, the only device listed is "Digital Out" and there is a message under it saying "The Selected Device has No Output Controls."

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.
