I got an old G4 and cleaned it up and hooked it up to a monitor, but when I start it- it shows the white startup screen and then just goes to black and i can't get an image on the monitor again. The computer is running and responding to the keyboard though
View 7 RepliesMy MBP was working fine and then froze while I was on the internet. I turned it off and on again by holding down the power button. It powered on and froze on the white/gray screen with the Apple logo with the spinning wheel underneath it. I restarted it again by holding down the power button. Now it freezes on an all white/gray screen. I've tried starting it with the disk in it and holding down the "C" key and starting it and holding down the shift key after I hear the start up tone. Neither have worked.

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?
When I boot up my MacBook Pro (Unibody 17" 2011 model), it maks the CD noise, chimes the apple chime, then shows a grey/white screen. normally, this would progress to a grey screen with the apple logo on it, followed by the login screen, however in my case, the computer seems to just shut down. the fans keep running, so i know it isn't powering down completely. i can't change the volume/etc. after the computer has done this, so i'm assuming it isn't a display issue (also the display flashes white). does anybody know what this sequence of events is a symptom of? i'd really like to get my computer working again.

The day after I installed the update(10.10.1) for Yosemite, regularly my iMac suddenly stops working by showing a white screen. After 10 seconds, the iMac reboots automatically and again shows a white screen. Than, it stops. No action. No noise. I'm always obliged to stop the iMac by pressing the start button and restarting by holding the 'shift' key otherwise I have to look at a white screen again! In the save modus, I can work(typing this story) and restart the iMac. After a while, the whole show starts again. What can I do? Installing Yosemite again and whiteout the update? Can I undo the update? This once, I made no backup before the update(Murphy's law).

View 1 Replies View RelatedRecently 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.

View 1 Replies View RelatedRunning a MBP (mid 2009) 2.26GHz on OSX Leopard 10.5.8. I am trying to boot from the Startup disk (OSX Leopard 10.5.2) and when I stick it in a restart, I hold C and it hangs on the screen before where the Apple logo would appear normally, as if it's trying to load from the startup disk. The disk spins up and I hear it, but it just hangs there. Only thing I can do is a hard restart with the power button.
I have started from the disk before, so I know it worked in the past. Also, OSX recognizes the disk when I'm logged in and I can even run the Installer (ask you to restart though).
I recently turned on FileVault (have restarted multiple times since then) but not sure if this has anything to do with it. I am trying to set a password for the Firmware so someone can't reformat without a pw.
My iMac starts up to a white screen and stays that way and won't start.

I was off of my iMac for an hour or two so my screen saver when on. I went to wake the computer and it was frozen. I tried using the keyboard and mouse to wake up the computer from the screen saver, but it would not work, so I powered the iMac down manually from the button on the back. I let it sit for 15 minutes, then I tried to start the computer up again. Now at start up, I get to a blank white screen with the spinning moving pin wheel, and that is it.Â

It makes the startup chime, and I've tried resetting the PRAM and PMU and none of it works. Apple store said they thought it was hard drive failure, but I doubt it because it won't boot from CD either. Do you think it's logic board failure?
View 1 Replies View RelatedMy 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!
View 1 Replies View RelatedMy partner's PowerBook G4 (17-inch 1.67Ghz) which, of course, ended it's Applecare on June 28th, developed a glitch on the screen today: a white line that is 1 pixel wide and runs the length of the screen. It just started out of the blue - no dropping of computer, no power surge, no external reason. One minute it was fine the next it had this line.
Any body ever encounter a problem like this? And if so, how did you get rid of it (either repairing it via a technician or by oneself) and how much did it cost?
I'm betting it's a sign that it's time to get a new computer.
