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?

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!

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.

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 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...

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...

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.

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?

6 month old MBP 15", been running 100% fine, plugged it into a projector the other day and it auto changed the screen resolution. I unplugged the device, went into settings and changed my screen resolution back to it's factory size as well as command & the minus key to make sure I wasn't zoomed in on anything.Â
I then did a system update for the following; Airport utility, Safari, Ricoh Printer, Digital Camera Raw, java, Itunes.Â
Restarted the computer as the updates had finished, then when turning back on the loading screen with the grey background, apple symbol and rotating loading symbol was zoomed in as much as the resolution would allow. So i restarted a couple more times, still the same thing - every time i turn the computer on the loading screen is massivly zoomed in, once it's done loading and moves to the log in screen it is fine.Â
I've tried plugging into the projecter again and editing my settings, that did nothing. It's like because i updated while the settings where wonky it's saved it somehow?Â

I have a problem with my MacBook screen. Everytime I try to turn on the MacBook, the blue screen appears for a second and then everything gets dark (but I can see that the computer turned on normally, it's just the screen that gets almost black, without light). Sometimes only the right side of the screen is blue and then gets dark just like the left one. I was looking for the problem and I perceived that the left side seems to be loose and I can't fix it. What should I do?

Loaded pics up for the 1st time from my 7d into Aperture 1.5 and left my computer on, woke up and it wouldn't come out of sleep. I did a hard shutdown holding down the power button and the screen just stays black and I never hear the chime, light on power button is solid white. Since I'm on vacation with my wife and infant daughter I don't have time to mess around troubleshooting but see it may be a failed logic board? Do they just fail randomly or what? My aunt that I'm staying with turned off a surge protector a light was plugged into, I was using her power charger for her MacBook Pro and only this morning found out it was plugged directly into the outlet below the surge protector was on that she flipped off.
Could that have created a surge on the other plug or something? She does this all the time with her MacBook Pro plugged in and its never created a problem, I'm writing this post from her computer right now! (Only brought the Mac out because my iPad wouldn't load the photos for some reason, don't know if it has something to do with the HD video or because I also had photos from my Canon 50d on there or if that has something to do with my Mac's problem?) I've attempted an SMC restart and it does the same thing? I'm now extremely stressed thinking I may have lost all my pics that I haven't backed up in months of my infant daughter. When I start it up I hear an initial sound of a hardrive spin or fan but then its basically silent.

I can hear the chime going off, but the display turns on you cannot see through naked eye, you have flash light onto to the screen to see very little, can you tell me why this is happening and how to fix this issue. Secondly, can you tell me how to fix this issue, my keyboard and trackpad doesn't work. Is it the problem of flex cable of both the keyboard and trackpad or is the related to software

On Sunday I popped a DVD into my 1.5 12" Powerbook (756 ram, 100gb hd) and then picture got incredibly screwed up. I guess the best way to describe it is there were a mess of colors and lines everywhere. Trying to move windows around left a window trail on the screen.
First thing after this happened was that I got all the data off, then I popped in the original Panther disc and wanted to do a fresh install, it installed alright from the disc (albeit with issues on the screen), but when it started again, there was a blue screen while the music was playing (the music that comes on when you first get your mac).
Anyone have any suggestions on what to do? From some forum searching it seems to be a video card issue. I'm hoping to salvage it some how, but if not, it'll probably sell as parts. It's been so good for four years now, I was surprised it conked out so suddenly.

My 2007 MacBook is starting up and making all the right noises but the screen stays black - looking on different forums it seems likely it is either the back light or the inverter that need fixing but in the meantime there is some things on there I need - I have an IMac as well and I have tried to connect the too so that I can view the macbook on the imac - I used a firewire cable and held down the t key on the macbook (but obviously couldn't see if it had worked) I then turned on the Imac and held the option key down but it only give me the IMac HD to start from and not the Macbook

I have a Rev A 12 inch Powerbook - 867 mHz, 640 RAM, 40 GB hard drive. The machine's always been reliable and has performed great over the years. I bought it the last week of July, 2003.
Yesterday, the Pbook was shut down, and I press the on button so it would boot up. Almost immediately, the hard drive makes a loud, whirring noise. The computer advances to the gray screen with the Apple logo, but it doesn't get past that point and the noise continues, as if it's a car engine that just won't start...
I'm going to take it to my local Apple Store in the morning, and hopefully the data, including my nearly 22 GB of music, can be saved. Any thoughts on how to get my computer working again? By the way, it's the original hard drive installed. Hopefully this is enough info to generate some ideas, I'm stumped.

I have a 24inch iMac 3.06ghz and seems to be stuck restarting. It will not get to the any screen (just stays black) and constantly restarts, the chime seems to get quieter each time, after about 6 times it comes back to full volume but will not get any further in the start up process.
I restarted it myself because the screen was flickering very quickly and seemed to freeze (this is the first time I have encountered that). I had to power down by the button at the back, then restart using the power button and now won't start up. All software fully up to date. Running Lion.

I have an early 2008, 24-inch iMac. This problem started after I installed an OS X Mavericks update (and has continued). Basically, after the screen is asleep for a while, if you come back and move the mouse / tap the keyboard, the desktop never reappears. The screen stays black but the mouse cursor shows up and you can drag it around. I've seen some similar issues that said they could get the app switcher, but that never happens for me. Just mouse cursor and black screen, no matter how long you try to wait it out or tap buttons. The only solution is a cold restart, although I think in the past I was able to fix by turning off energy saver settings for putting the display to sleep. It doesn't happen every time, I'd say it happens over 50% of the time. The problem actually kicked in with one particular App Store update of Mavericks. I believe it was 10.9.3 if I recall correctly.
