OS X :: Mac Seems To Work But Has Blank Screen
Sep 15, 2009
When finished, I normally put my mac into standby mode instead of turning the power off. Last night, I did the same. When I tried to power on today it seems like my mac is working (the buttons beep when pressed and hear the hardrive), however, the screen is blank (never turned on). I believe if I can actually turn my mac off and on again it may fix it, however, I have already tried taking the battery out and putting back in to no avail and I think everytime I try by pressing the power button it goes into standby mode. Is there a way i can force my mac to turn off instead of going into stanby mode by pressing certain buttons since I can't see the screen?

New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.
Info:
iMac (27-inch Mid 2011)

Got this mac friday but haven't really played with it before yesterday. My problem is:
1) Yesterday I went for logging in to facebook, but suddenly the screen went green? Had to close the mac down and start it again.
2) After I had turned it on and was on the desktop the screen (with me doing nothing) went white, and I had to do the same again.
3) This morning when I wanted to turn the mac on, it wouldn't! But few hours later I tried again and there I could turn it on by pressing esc + start button.
Should I call for a replacement? (Already had two - 1 with dead pixel and 1 with creaking).

1 month past warranty expiration and now my screen goes blank when I adjust the angle. Is this usually something major or just loose connection?

I was using it in my bedroom, it was plugged in. I went to make some food, and upon my return I am greeted by a blank screen, probably just a hiccup right? So I held the power button down expecting it to spring back in to life. But it didn't. It wouldn't turn back on. At all. Luckily, I thought, I have my old 2006 Macbook that I keep as a back up just for times like this. As it hasn't been turned on for a while, the low battery warning comes on, so I plug it in. 10 seconds later, it hibernates. I switch it back on, but it keeps hibernating for no good reason. So I think restarting it will solve the problem. It didn't. It too, now wouldn't turn back on. At all.
In the space of a few minutes, they both completely died. I've tried resetting SMC, PRAM, everything I've found on Apple's support page and forums like this. Nothing has worked. The light on the power cable glows orange when plugged in, so it is still charging, and the battery indicator lights on the side of the MBP work fine. Aside from that, they are both completely lifeless...........

I've got a 15in aluminium powerbook, a couple of years old. So far I've had nearly everything go wrong with it. replaced screen, knackered hd, ram port failiure, and a battery that lasts 10 minutes.
I recently replaced the harddrive, as the standard issue one packed up a few times. I followed the instructions on ifixit.com website. To my delight I actually managed to do it, and the pb worked well for a few weeks. Then suddenly, the screen froze and faded to white. So far I've tried everything -
Resetting the pmu. Resetting the pram and nvram. Opened it up to check I reconnected everything.
and checked to see if the hd is still working starting it up from another computer, and it works fine. Everythings still there. Someone also said if you hold 'R' key down on start up it resets the lcd.
BUT STILL BLANK!!!!!!!!!
The screen still seems to turn black after a little while, indicating the energy saver is still on. I'm thinking I may have dislodged an lcd connection or something?

I have a problem with my mini/quicktime setup and i was hoping for some help from you all at macrumors...
Here is the setup
This system is setup for a admissions office in which we have a mac mini set up to a LCD screen that is all mounted on a wall.
we have the mini on timer to come on from 1230-5pm and when the mini comes on, quicktime is set to automatically open and play the admissions video.
Now here is the problem:
when I turn on the LCD every day, the screen is blank but Ican still hear the video, I figured it was in hibernation so i move the mouse and hit the keyboard and nothing. i need to push the power button and hold it for a couple seconds then the movie comes on but the video is choppy.
here are the specs on the mini: 1.25 power pc G4, 512 Ram.
its old but its only function is to play this video...

when I turn on my computer there is a blank screen. You can still hear the normal noises coming from the computer like any normal boot-up. But if I let my computer sit for a while without turning it on, it will turn on with weird almost static noises. If I force shut down then try again, I get the normal boot-up noises. I tried the safe boot-up method,holding down the shift button while turning the computer on, but no dice. I actually tried this method on both the good and static noise boot-up.

I am trying to set up boot camp on my new mac mini. The primary reason is that 10.6 intel macs don't support my version of mac photoshop (Photoshop 7). I have an XP version of photoshop installed on my old laptop, and want to boot XP on my mac and move it over. However, when I tried to install Boot Camp, and re-started with the windows CD in from Boot Camp, I had a gray screen for a bit, then a blank screen.
I have a brand new Mac Mini, with OS X 10.6, and I set up the boot camp partition successfully. My windows CD is XP with SP2 as apple claims is required.
Additionally, I have an external hard drive with a .bkf file on it from a backup of my old PC laptop that has photoshop in it, but I can't extract that to my BOOTCAMP drive, at least without windows already installed on it.
I tried some other windows CD's, and a windows DVD that are supposed to be bootable borrowed from friends, using the boot camp application, with the CD in, at least XP SP 2, and I still got a blank screen as it re-started, and thus have been unable to install windows.
Is there another way I could install windows? Perhaps from my .BKF file? Is there something I might be doing wrong? I do have an older monitor, a viewsonic 17 inch, and I'm using an apple adapter. Could it be that windows install CD's don't support my graphics card? If so, how am I supposed to install windows? Also, my keyboard doesn't seem to be recognized either. It is a macally ikey extended keyboard, and I can't even get the caps lock light to turn on while it is trying to load of the windows XP disk with boot camp.

Not even a week old!! Computer was asleep for about 2 days, woke it up the same way with a few taps on the keyboard and it just started to beep. Tried to turn it off but nothing. Nothing on the screen, just beeping. Pushed the power button and beeping. Unplugged it and waited 5 minutes and pushed power button and beeping with nothing on screen. Its sunday and it hurts my stomach to think about the lengthy process this will be to get a new one or get it fixed. My wife says to call, but I tell her that if there even isn't anything on the screen then what can they do over the phone. Is it possible the memory went bad. What would cause this? Its plugged in a power strip.

I need your opinions; since the 10.6.3 update my iMac has begun to freeze to a blank screen. I think this may be a sign of a dying logic board, however I question this as I don't have the freezing problem with 10.6.2. Picture of blank screen attached.

My Mac Pro arrived today and of the six or so times I've restarted this has happened three times:
I get the normal grey Apple logo screen then as it switches to the login screen the screen goes black. The monitor doesn't go into sleep mode, it thinks its getting a signal. If I hit the power button and put the Mac to sleep then wake it up the login screen appears.

I had a power outage while the computer was running, and now whenever I try to login as my admin, after the password part it just goes light blue. Full screen blank out. I can use my non-admin accounts and use the admin password to change permissions.

I have a MAC IBook (800 MHz 32VRAM) ibook and when I turned it on this morning I got a blank screen. I tried turning it off and on several times to no avail. I know the computer is on because when I touch the sound button (F5) I could hear the noise, but I have just a blank screen. I am assuming its a monitor problem or did I touch a function(s) key by mistake and it blanked the screen.

I'm trying to upgrade to LION to move to iCloud...the folks at the genius bar recommended that I go from 2gb ram to 4. They gave me the website to purchase the memory and told me how to load it. Prior to loading, I shutdown the computer and unplugged it. I then removed the 2 1 gb cards and replaced with 2gb cards. The loading seems to have gone fine, but all I get is a power light on the front of the case and a sound that makes me think it's running....the screen is totallly black though.

I have built a charity website for the Gurkhas [URL] there is a secure members area which requires the member to put in their email address and password. One particular elderly member with an 9 month old Apple Mac running latest version of Safari finds that when he puts his email and password in and hits 'Sign In' the input lines go blank.Â
The software is Serif Webplus X5 and is working with Windows and IE and most other Apple Mac/Safari users. I am not an expert in the Mac/Safari environment and have remotely logged on to this members machine and cannot see anything obvious.Â
I and Serif have both tested the particular webpage with Safari in a windows environment and several Serif Forum users who are Mac users have tried the page with no problems.Â

PowerBook, Safari

I am currently running OS X Lion. There are no system updates. My macbook pro JUST started doing this. It never did it before. When I shut my computer and let it sit for however long and then open my computer, the screen comes on, and then about 5 seconds after that, the screen goes blank. In order to turn my screen on, I have to adjust the brightness on my keyboard EVERY single time.

I do computer repair and have run into an issue that I cannot figure out. My customer has an iBook G4 and the screen will stay blank as if it's off even when the power button is pressed. I've tried turning it on only on AC power; I've tried Cmd-Option-P-R; I have tried applying pressure in various places. When I asked my customer about what was happening when the issue started, he said his kids were on it, the battery died and the next time he tried to boot it up, it wouldn't work. It gave him neither errors nor lines on the screen; it just wouldn't turn on. Now the strange thing is everything else works. The fans spin, the hard drive spins, and it gives the startup sound. I tried to see if maybe the brightness was to low but that didn't work either.

I'm trying to fix the blank screen but I don't want to use any heat. I found this method. This is the only one I found that didn't use a blow torch or such. [URL] Do any of you know where I can get a heatsink like that or if just the fins are available anywhere? I'm not sure what to search for when I do it online and I tried different variations but all the heatsinks I find have fans. I don't want to spend more than I have to since I don't need the fan. I also don't really want to buy online unless I can't find it in a retailer.

I just got this iBook 12" in the mail been to a mac shop before I bought it where the owner was told the screen had died. Motherboard was said to be Ok by the repairer. I replaced the screen with a know working one and the screen was dead. Then after the fiddle of pulling it apart again wondered if I could use the hard drive on another ibook. The hard drive I put in another iBook which loaded up fine with display. Later I tried again but it was a dead screen? Is it that both ibooks have faulty motherboards? Motherboard determines a display? Or could it be the display module? What else could cause dead screen? Cables good.

When editing a photo, adjusting things in the Adjust pane sometimes makes the picture disappear and I have to click Done to go back to the main window to see anything. Anyone else had this problem and has anyone found a way to solve it? I'm running latest iPhoto and SL. I've trashed Prefs, of course.
