PowerPC :: IBook G4 Start Up - Screen Remains Blank

Aug 14, 2006

I have had my g4 for about two years and all of a sudden the thing decided that it's not going to turn on anymore. Power is getting to the machine and a certain amount of whirring is heard but not the signature! as it starts. The screen remains blank and would stay like that all night if I let it. The only thing I did differently before this appeared was to take it to work in a different bag a few times. Rucksack before, Side bag (more vibration).

OS X :: Mac Pro Starts Up But Display Remains Blank?

May 28, 2009

A few days ago I began having trouble with my Mac Pro (Dual Proc. 2.8 Ghtz, 2 GB RAM, DVI display, OS 10.5) It would not wake up after going to sleep. I did the PRAM and SMC resetting thing, and I thought it had worked, but now just two days later, the computer does turn (the bell rings a la Wall-E and everything) but the display remains blank. I plugged the display into a MacBook pro and it worked fine, so I'm guessing the problem is the DVI port. 3 questions arise:

Does anyone know of a sure-fire way to find out if the DVI ports ARE the problem? I did hook up the computer to a Power Mac (G4 running OS 10.4.11) in transfer mode, and the HD did load, I also performed the first aid thing on it and everything came back positive.

Does anyone know if changing the DVI ports is simple enough to do, or should I definitely leave to a professional? (I am fairly familiar with putting stuff in and out of it)

Should I buy the DVI card directly from Mac or can I get by with a less expensive brand?

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!

Software :: Got Blank Screen On IBook (800 MHz)

Sep 27, 2008

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.

Hardware :: IBook G4 Blank Screen On Startup

Nov 19, 2009

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.

Laptops :: Fix IBook Blank Screen With Heatsink Fin

Jan 16, 2009

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.

Hardware :: Cause For IBook Dead / Blank Screen?

Aug 22, 2009

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.

PowerPC :: G4 Ibook Dead - Blank Screen - Fan Runs On High Speed?

Nov 22, 2008

I purchased a used ibook from owc in January and have had it back to them twice for repairs. Lately, it stopped booting up again and they told me to use [URL] to take the mobo out and ship it to Arizona to have the solder refloated. I did and got it back, put it together and it would boot up, only to run for 15 minutes and shut down. Thinking I missed something, I dissasembled it today and reassembled it. Now it turns on with a blank screen, the fan runs on high, and it will go no further. I tried to reset the power manager, reset the p-ram, the hard drive is only a few months old and my brain is getting fried with frustration.

OS X :: No Display At Screen - Remains Black

Dec 2, 2009

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?

IBook :: Stop G3 Doing Hardware Test Every Time It Starts Up?

Jun 5, 2014

Every time I startup my iBook G3 it makes the bong then it shows the apple the logo but then a black screen with writing appears and does, what I think is, a hardware test. It is very annoying for me and I don't know how to stop it doing this everything it boots up. I have tried restoring the iBook to factory settings and that did nothing.

OS X :: Early 2008 MacBook Pro Won't Boot The Screen Remains Black?

Jan 2, 2010

I have a problem: when I restart my Early 2008 MacBook Pro there is no "chime" and the screen remains black. The keyboard doesn't light up or respond to any input, and worse still, the "lid button" light on the front of the notebook remains illuminated, it doesn't blink, it just stays on, shining in my face. I loaded a CD into the optical drive to see if I could use the keyboard to eject it, but this test failed. Now, when I turn on my MBP, I hear the optical drive spinning and the quiet whirr of the fan inside.

I looked on Apple's support website about what to do when a Mac refuses to boot. I tried all of the methods they listed, but since my Mac doesn't respond to keyboard input, all of the techniques failed. Having exhausted everything I could think of, I decided to post here hoping someone could suggest something. I was just on the verge of completing my portfolio website and I would like to salvage my data at least.

OS X V10.7 Lion :: Macbook Pro Screen Remains Black After Opening Computer

Apr 29, 2012

When I open my macbook, the screen remains black (as though it's in sleep mode). Adjusting the brightness always fixes this problem, but this is a temporary fix. The brightness is not at zero when I adjust it after opening, often I need to dim the screen to reactivate it.  

This problem is not: related to *clamshell mode*related to unintentionally dimming the screen. related to any of the settings in the Energy Saving panel in system preferences 

Extra info: The computer seems as though it doesn't actually enter sleep mode when I close the computer.I don't think there are any processes running that would prevent sleep mode. I really just want the computer to go to sleep properly when I close the screen and more importantly, that it wake-up when opened, or at least when a button is pushed aside from the brightness buttons.

Info:MacBookPro, Mac OS X (10.7.3)

MacBook Air :: Laptop Suddenly Froze And After Restarting Screen Remains Off

Dec 9, 2014

I bought last year (18 month ago) my MacBook Air. Suddenly it froze and after restarting the screen remains "off". After connecting an external screen I can go to the first opening screen but the cursor won’t move. I tried to use the “Command,” “Option” and “Esc” keys on the keyboard at the same time to bring up the “Force Quit Applications” window but it doesn't work. After restarting I'm back at the same screen, still frozen.

MacBook Pro :: Appears To Turn On But Sleep Light Remains On And No Start Up Screen?

Jul 18, 2010

This morning, I synced my iPod with my MacBook and upon completion and permission to disconnect the device, I pulled out the USB cord. At that point the computer instantly turned itself off, and when I hit the power button, I could hear the system trying to start up, but the screen remained black and the sleep light glowed continuously. I unplugged the charger, took out the battery and put it back in, and tried all the troubleshooting tips under the Apple Support guide with no success. I also discovered that when I closed the laptop while it was "on," it would seem to boot up a little more before returning to the black screen. I left it alone for a few hours, and when I tried again to turn it on, it booted up normally and as I was searching for updates, it shut down again as it had earlier.

Does anyone have anything for me to try? I don't want to have to take it into a shop because I can just barely afford to, but I need this computer! Any suggestions would be greatly appreciated :-)

OS X :: After The Screen Saver Starts - MacBook Locking Up?

Apr 24, 2008

After the screen saver starts (set to go on after 1 hour), my MacBook locks up 90% of the time when I attempt to wake it up. I sometimes hit the trackpad and sometimes I hit command. It is hit or miss on which one will work.

I have to hold the power button to restart it.

I have it plugged in all the time when it's at home. Under energy saver I have both settings set to go asleep after 2.5 hours.

I have no issues when I close the lid to put it to sleep.

Software :: IMac Starts Itself With Reboot Screen

Jan 9, 2009

In the last three days my iMac desktop has begun starting itself up. There is an audible beeping (three or four beeps) and the on/off indicator light blinks rapidly. When the screen comes up there is no desktop but a gray background with reboot instructions. When I type the reboot words "mac-reboot" the desktop comes back.

Under Logs in the system profiler I see the following message:
CGXDDisableUpdate:Updates disabled by connection 0x66-3 for over 1.000000 seconds
and
CGXBlindSurface returns-536870210
The computer is rather old, is running OS X 10.2.8 and has never done anything like this before.
