Power Mac G5 :: On Start Up Screen Is Black

Dec 13, 2007

When I start my computer up in the morning everything else starts normally. First the light comes on on the front of the computer and on the bottom of the monitor, then the start up tone rings and the computer is fully running. But my monitor is black and I do not get the apple picture or nothing on the screen. I thought my monitor was going out, but we have another work station the same and I switched the monitors (same 27" cinema screen as mine). I can actually use the other computer and network into my computer and fully use everything on my computer. But my monitor is black (no display)! I have contacted MAC and have reset the PMU button many times and sometimes this works, but most of the time it does not. I just keep restarting the computer and finally it will start up normally with the display and everything.

MacBook Pro :: Freezes Randomly And Beeps When Coming Out Of Power Down Sleep

Jun 27, 2014

So, I have a late 2011 MBP 2GH i7, OSX 10.9.3. 500GB HD 16 BG 1600 Mhz DDR3.  

The problems started a while ago when the computer started freezing at random times. The mouse would move and there was no "pinwheel" but the computer was unresponsive. When I closed the screen the power was still on and the screen did not shut off. The only way to reset the computer was to hold the power button and do a hard reset. I don't remember if I replaced the RAM from 4BG to 8GB Crucial Memory before or after the computer started freezing, either way, shortly after or around the time when I replaced the ram the hard drive also failed.

I replaced the HD with I believe a Seagate hybrid drive with a small solid state segment. This whole time the computer is still freezing and now since I have a hybrid drive the Apple store can't support because it's not factory specs and MacMall here in Santa Monica can't find anything wrong with the hardware or software after running all of their tests. 

At this time I have a feeling it is the ram so I purchase a new 16GB Crucial RAM. Everything is great till it yet once again freezes in the same way as before BUT!! Now if the computer sleeps because the battery run's low, when I plug it in and the computer reboots (grey opaque screen with the vertical lines as the bottom) it starts beeping 3 times. I hard reset via the power button and the computer boots up as normal (although a little slower).

Power Mac G5 :: Distorted Graphics And Screen Go Black

Dec 11, 2007

After the 10.5.1 software I'm having a problem with distorted (stripes etc.) icons and menu dropdowns. Apparently not on my desktop or programs like Safari, Mail etc., only on icons and menu dropdowns, which I find odd. Sometimes it's gone, but after some time it reappears again. Anyway, sometimes my Mac (iMac G5, PowerMac12,1, 1.9 GHz) is going bonkers completely, which results in a first pink, then black screen. A hard shut down is then the only option. However, I guess it's videocard related (ATI Radeon X600 Pro). I did all the tests, fixes you can think of, but without any results. I contacted Apple support, but because this is an iMac, you can't just replace the card, they told me that the whole motherboard should be replaced, which will cost me approx. 700 EURO. Of course I am not willing to do that, which means that I'll have to buy a new Mac. Of course a new Mac is always a delight, but I find replacement after just 2 years unacceptable.

Power Mac G5 :: Failed Installation Leaves Black Screen / What To Do?

Dec 13, 2007

I have been given a 1.6 Dual G5 running 10.3. I tried to upgrade to 10.4, the first disc installed but crashed several times on disc 2. I had run DU previously to check there were no problem. Each restart took me back to disc 2 which failed to install. I then tried to install 10.5 (Leopard) booting directly from the disc, it started then crashed leaving a black screen with the following promt:
local host:/root* (a hash not an asterisk!)

Anybody offer any suggestions as to what I should do?

Intel Mac :: Black Screen And Flashing Power Light?

Jun 15, 2012

I installed several system updates on my 2007 iMac last night, running OS 10.7, and today I can only get a black screen with a flashing white power light when I try to start up. My computer will neither start up nor completely shut down, and my wired keyboard won't communicate either.

Power Mac :: Random Black Screen - Is It Monitor Or Graphics Card?

Mar 21, 2012

Do not want a nuisance to escalate into a serious problem thru benign neglect. Random black screen -- Turn monitor off then on, and all comes back fine. No loss of power in machine, no fan quirks, no overheating. Is it the Monitor? or the graphics card?

Power Mac :: Have A G4 Dual 1GHz, Recently It Cannot Boot, Goes To The Black Screen

May 2, 2012

My G4 recently will not boot. I get the chime, it starts to boot, but almost never completes before I get the "you must restart you Mac" screen.I have the correct hardware test disc. I started using that two days ago. It still has not completed testing the logic board and the system is unresponsive. I guess that means the board is fried?

Power Mac :: Mac Pro No Boot Sound, Black Screen And Loud Fans

May 25, 2012

I've had problems with my Mac for a while now. First of all, it indicated ram problems with 2 beeps. I later fixed this by moving and changing around modules. It was solved, but now a new problem. The Mac seems to turn on, making its iconic sound for startup, but the screen remains black. After about a half to one minute, the fans go crazy and I have to shut it off. I've tried a few things like holding shift or alt, but that doesn't work as it doesn't even display a white screen. 

I need to know what to do and I don't really have the time to buy new parts right now. I'm really a windows based pc fixer by the way so I'm new to fixing macs.

MacBook Pro :: Screen Freeze / Shut Down / 3 Beeps

Dec 5, 2014

my macbook recently started freezing and then shutting down giving 3 beeps afterward. I know 3 beeps is traditionally RAM, but here is a picture of my screen when it freezes. Do you think its GPU and logic board problem or is it really the RAM?

PowerPC :: 800Mhz EMac - 3 Beeps And Flashing Light On Power Up

Dec 12, 2010

My brother has a second gen, 800Mhz eMac (the one that could be overclocked to 1.33Ghz - the earlier PC133 ram model). Since about 1.5 mths ago, when he powers it on, sometimes it will not power on, and other times it will give three beeps (diagnostic pages say bad RAM) and a flashing power/sleep light in unison with the beeps. Did this vintage suffer bad caps? I recall that it was only the 1.25Ghz model that had bad caps, but I could be wrong.

OS X :: Screen Sharing - Remote Mac Goes All Black (even "in Person") And Needs Power - Down?

Jul 5, 2009

I VNC to my iMac all the time (usually from iPhone with Jaadu, sometimes from another Mac with Leopard's Screen Sharing function: Connect to Server vnc://....) But lately it only works for a couple of days. After that, the remote computer's screen goes black and accepts no input. (But I can see/move the mouse cursor.) Once I get home from whatever trip I'm on, I then see that it's the same in person: all-black, no response to clicks or keys. I can move the mouse but I can't do anything at all. There's no solution except to force power-down.

For security, I run the "Computer Name" screensaver with password lock. The first time the black screen appears I see just a flash of the password dialog and then it's gone. After that, I never see anything but black (and the mouse arrow). The remote computer is NOT crashed, because it accepts the VNC connection request and password, and because it keeps churning out work from Folding@Home (which I can see on my stats page). But after a day or two away (maybe one VNC session per day) the screen and input are gone. Anyone else see this? (The only two changes made to that system lately: a new version of EyeTV software--but it's not recording or anything. And the 10.5.7 update. I'm guessing it's something new to do with 10.5.7.)

OS X V10.5 Leopard :: IMac Screen Went Black - Starts Up With Black Display

May 24, 2012

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

MacBook Pro :: Unable To View Full Screen Mode / Second Screen Turns Black

Sep 16, 2009

So I have a DYNEX 21 inch HD TV conected up to my MBP via the VGA connection route. My problem is that when I want a program (or more specifically in this case a game) to go into fullscreen mode it automatically goes to my primary monitor and turns the other screen black. I know I can switch the primary monitor from my actual laptop screen to the TV however I just want the game to be full screen on the TV while still having access to my dock and everything on my laptop.

MacBook Pro :: Faint Mark Of Light Color On Black Screen / Nothing Visible When Screen Is Off

Jan 4, 2010

I have a problem with my screen - when there is something black on, I can see a faint mark of a lighter colour. I have tried to take a picture, please excuse the poor quality. There is nothing visible when the screen is off, even under close examination. Is it less visible when lighter things are on the screen, and invisible when the screen is white.

No drops or liquid spills. Will this go away on it's own? Any fixes?

MacBook Pro :: Why Does Screen Go Black Every Time Move Mouse To The Lower-left Hand Corner Of The Screen

May 5, 2012

I've had my mac for about three years now and everything was working fine. After I installed lion, I notice that this started to happen. I don't lose any of my information though when it does that. It just goes into a sleep mode I guess? Anyways, is this a feature from the lion update? Something standard?

MacBook Pro :: Screen Is Black Does Not Want To Exit Screen Saver Mode?

Jun 2, 2012

When my MacBook Pro 13" i5 goes into screen saver mode, which is black, it won't return to normal mode. Tried all keys, trac pad, closing the lip and re-opening it,  and it won't respond. The only thing that works is holding down power button for hard shutdown, then restarting it. It has happened 8 times in the last 2 weeks.
