IMac :: 2006 Screen Goes Black?
Aug 4, 2009
Let me start by saying I have swapped the ram in the computer and the problem persists. I've also tried resetting the PRAM. I have unplugged all devices except the keyboard and mouse. I have reformatted and installed OS X Leopard, Tiger and Snow Leopard. I have even encountered this issue while the computer was running from the install disk. I'm pretty sure software, ram and third party devices can be eliminated from the possible causes. The computer continues to run after the screen goes black. I am connected to it right now using screen sharing, so I know the computer is still working. Putting the computer to sleep and then waking it up temporarily brings the screen back until its next random blackout. I have opened the computer to replace a dead HD, so I suppose it is possible that I knocked something in the process, but I did that back in December and the problem is a relatively recent development. I would really prefer to fix this myself, if I could only figure out what the problem is.

I have a 2006 Macbook that when powered up, the screen stays black, the machine beeps 3 times, and sleep light blinks 3 times before the process repeats over and over. When doing a search, I saw something about the RAM but

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?

I have a late 2006 24" IMac which has a myriad of issues. The most concerning to me at this point is the occasional appearance of a 1-2 pixel wide horizontal line which runs from 2" across to sometimes as much as 12" across the screen. It happens most often on the desktop and in firefox. It disappears as mysteriously as it appears.
Could the graphics card be going bad? Any ideas on what might be happening and how I might be able to solve this.

My screen freezes from time to time and CPU overheats.I have increased the fan speed with SMC download but still happens 2-3 times a day when downloading or watching video, also when using SKYPE worse when using both? BBC iPlayer does not make it freeze?

*Apple officially supports 2 GB of RAM, but third-parties have been "unofficially" able to upgrade it to 3 GB or 4 GB of RAM (it can hold 4 GB but cannot fully utilize the memory beyond 3 GB).
Im thinking about adding that 2gb ram to make it 3gb. but i want to know what are the problems that i may face. Would i be void of apple warranty if anything happens?

I purchased a Hitachi Travelstar 2.5 Inch 500 GB 7200 RPM SATA II 16 MB Cache Internal Hard Drive 0S02858 to replace the dead hard drive in my black macbook (late 2006). I have the old hard drive out. Here are my 2 questions.... first, there is no pull tab on the new hard drive. How will I get it out if I need to? The one I removed is a Seagate and has a covering on the top with the plastic pull tab. should I put that over the new hard drive? It comes right off the old one. Second, when I compare the connectors there is a section, looking straight on at the pins, on the far left that in the old one has 4 pins. In the new Hitachi there is just an empty compartment. Does that mean it won't work? Or should I just try it? If I leave it without the plastic pull tab how will it come out if I have to get it back out?

I have been experiencing some unusual problems with my imac. While on the internet today my computer crashed on me twice, the first time the screen just showed a bunch of vertical lines, the second it flashed some random colors then went black. After the screen change the computer was unresponsive. I have a bad feeling, is it due to overheating, a bad logic board or something else. This is the first time I have ever experienced this on a mac. Has anyone had any simiar issues? Or am I up **** creek? I can't really afford a new computer seeing that I just bought an iPad (it comes Saturday). I am not sure if my computer is still under apple care and even if it was I won't get it back by the time I have to go back to college. I attached a screen shot of my computer temps.

When I turn my Imac, it goes from the white screen to a black screen, then blue and then desktop. The whole process is fast, but is not normal. (at least is not like my previous MBP or the videos that I have seen on youtube) At the black screen stage, I can see some boot up information, etc, It is fast so I am not able to read it all. It looks like when booting an old windows or dos machine How can I change this? Is this normal? It also shows the screen when I shut down.

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.

The screen randomly turns black without any major reasons. It doesn't seem to be a sleep mode/screen saver thing as the music continues to play on. I can adjust the volume or pause the music with the keyboard but the screen just won't turn back on. I have to shut it down using the power button and it happened several time the last couple days. Anyone else experience the same thing and got a solution?

I decided I was going to install XP on a bootcamp partition tonight and everything went fine until I installed the Bootcamp 3 software. After installing the Bootcamp drivers the machine rebooted and I ended up with a black screen in Windows. I did hear the XP welcome music so I figured it was a display driver issue. I rebooted into safe mode and deleted the ATI 4850 driver and restarted. After removing the bootcamp driver everything was normal again other than the fact that I only had the default Windows drivers running.
What am I doing wrong? I installed XP off of an XP disc with SP2 already on it and ran the Bootcamp install off the Snow Leopard disc. Finally, not sure if this matters, I am running one of the new i7 iMacs.

This just started yesterday (May 31st). I keep everything updated as it comes out and nothing new has been installed in the last couple of days.
When I need I wake up my iMac (now requiring a keystroke or mouse press instead of just moving the mouse), the screen comes up black, but the cursor is there and moves around fine.
It stays black for a while (15 seconds or longer, but it feels like forever) and then it finally comes up completely.

The screen/crt of the imac that I have been using since about '98 went black - this actually happened a couple times previously but I was able to get back in (no idea - one of those things where out of frustration you just start pushing everything at once and it suddenly pops back on). I have tried everything - the internal battery, that little button on the motherboard (not sure if that is what it is called) that resets everything, the connection of the main power button on the front, etc. I am fairly sure it is stuck in sleep-mode or something (no beeps, hard drive doesn't make the usual booting-up sounds but you can tell that it is receiving power) but after months of wasted effort I finally gave up. I bought another slot-loading G3 and would like to swap hard-drives between the two - I have taken my old G3 completely apart so many times that I am totally comfortable with that aspect but have hesitated because if I somehow blow this one I will be left with nothing.

For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.

I have an rev. A iMac G5 that was purchased in January of 2005. The applecare has long expired. However, in May of 2008 due to factory defect Apple replaced the logic board, power supply and super drive [URL]. In December 2008 after experiencing problems with my hard drive I took my computer to the apple store. There they said it was dying and it would be cheaper to replace it myself. After purchasing a seagate hdd [URL] my computer won't recognize it. It stays at the black screen while the power light glows. After a few minutes the fans kick in at full force. I tested the hdd in another iMac G5 rev. B and it works fine. Any ideas on what the problem is or how to resolve it?

Recently i've started to experience my iMac screen flickering for approx 2 seconds, and then turning back on. I was wandering if this was a common problem with this model of iMac (purchased mid-09, 2.66ghz 4gb ram model). I had read of such a problem with the new 27", and in some cases even with the 21.5".
I have only recently begun to use the iMac for relatively graphically-intense tasks, and was wandering if perhaps it could be a dying graphics card (or perhaps it was always faulty, but the lack of intensity of any programs run never pulled it up originally?), or if maybe it was an issue with the LCD?

I was playing Diablo II and my screen froze, and the same half second blip of sound kept playing over and over. I couldn't even force quit, so I held down the power button until it turned off.
Now, it won't turn on. When I press the power button, there is no chime. Oddly there are an inordinate number of fan wooshes. Like, I hear a woosh from the right, which is normal, but then I hear a woosh from the left, then another in the middle! I am being bombarded with wooshes!I've tried holding alt, or holding shift, or holding alt+s while starting up. No dice, although I do get fewer fan blasts, which is normal.

Middle of last month I bought a 20" IMac. Everything was fine up until about 1 week ago when the screen went black. I clicked on the mouse button several times only to have a password box pop-up. After filling in the response, all was fine.
Next, same scenario but the password box didn't appear any more. The only way to get the screen back was by a forced restart.
I turned off the screen saver, set the 2 controls in energy server to off, unchecked the box at the bottom left & put "auto login" to to on the Accounts window.
Problem continued.
Next move was to zap the pram, this was 2 days ago. The screen didn't go black but often asked for my pw. It's now back to its beginning phase which is a forced restart !!
I was told that it was due to Leopard 10.5.2 & am considering going back to 10.5.1

Just installed Windows XP using bootcamp and usually no problems switching between operation systems. Recently started using an USB modem for my wireless internet connection. Internet works on both Mac and windows through the modem. Now the problem is whenever I restart or switch on my computer, it shows a black screen if I choose windows partition to boot. No problem if I start through mac partition. If I unplug the USB modem, everything goes fine and I have to plug the modem after starting windows. Is there any solution so that I can permanently plugin the USB modem and avoid booting problem?

I tried to install Windows 7 via Bootcamp a couple weeks back, but shortly after it failed, I deleted the Bootcamp partition in Bootcamp Assistant. However, whenever I want to boot my computer, it tries to go into the Windows Installation, but it gets stuck on the flashing underscore on the top left of the black screen. Henceforth, whenever I want to boot into OSX, I have to hold down both ALT keys. is there any way of fixing this so the iMac boots STRAIGHT into OSX (like normally)
