IMac G3 DV 600 does not start up
Hi mac fans,
I read about 20 discussions about the firmware problem and flat batery problems that lead to boot failure. My problem is different. I have been using OS X Panther for 10 months with correct firmware. About a week ago, my iMac did not boot up. The power button flashes for 1/10th /sec and then nothing.
- it is not the batery
- it is not the firmware
- it is not the stuck power button
What the ** is it then?
Thanks for any suggestions.

Hey guys! It'd be great if there is some answer to this problem. You could have read my thread earlier...my iMac G3 500mhz died Dec. 22 and I have the same flash of the power button but only when I first plug it in. A whir of the hard drive would be music to my ears. It seems to me anyone who tries to suggest booting from a CD has never experienced the hopelessness of the situation - it ain't booting! How would sticking a CD in it help? Even if I did try it. I also wondered if I had pushed the PMU too many times and if it needed to be actually closed up to work, etc... I am wondering if there is just a point when these great iMacs' time is up and there is nothing we can do about it.
Do you think if I put the hard drive in a different, operating iMac it would work? Guess that would answer my thought that maybe the hard drive just died, eh?
There are the troubleshooting steps you can go through if you get to the Mac Manuals and find the one for your computer. I didn't get through all of those because I am not sure I have the tools and definitely no access to fuses and other parts, etc. I am not getting rid of it yet though in case someone more capable than I can do something with it.
I also posted a thread under OS 9.x if that helps you:

I must say it has been of some comfort but not very encouraging to hear so many people having such a similar problem. Good luck everyone!

Hallo ,I have an IMAC 21.5. which does not start.When i press the power button i hear only beep with an interval of 4-5 seconds.Some times when i take off the RAMS and put them again then get a white screen and shows that i have to insert a bootable device.Then i bought OSX mountainlion on line and wrote it on a DVD and tried with a USB key board to start the DVD.But does not work.Please help me to get this imac work.
Thankyou in advance for your help.
TerrenceHey terremo,
Thanks for the question. From the information you provided, it sounds like the iMac is successfully turning on, however video is not displayed. These symptoms can usually be isolated further by the troubleshooting steps in this article:

New iMac shuts down but does not start as set in Energy Saver Schedule
Set Energy Saver schedule to shut down at 2300 and it does so at approx 2305. Set schedule to start up at 0700 and it does so the next day but NOT after that (have repeated the exercise 3 times - same result!).
You should not be having "Energy Saver" problems on a new iMac.
Have you tried any of the following?Restarting your computer?
Doing a PRAM zap?
Since you are still under warranty, strongly suggest that you take full advantage of it by calling Apple tech support. Especially if you are within 90 days of your warranty and/or have AppleCare. -
IMac (24", late 2006) does not start
Hi
I am no native english speaker so please excuse my english. ;-)
I have a problem with my good old iMac (24", Late 2006, Core2Duo). When I start it the screen stays black, and the standby LED is permanently on. The gray screen doesn't appear, but the computer seems to boot normaly (usual hard disk sounds).
When I start the iMac with long power button pressing, it starts, the standby LED flickers and I hear one long beep. Accouding to the Apple support information one long beep means "firmware restoration in progress". But we didn't start a firmware restoration and the last shutdown was a normal one, no hard power off or something similar.
I already did a PRAM/NVRAM reset and a SMC reset. But nothing changed...
Is there anybody who could please help me?
Kind regards
DirkDirk,
Run Apple Hardware Test in extended mode 2-3 times at a miminum. If errors appear then you have confirmed a hardware fault and the machine needs to be repaired. However AHT isn't the most reliable test in finding errors, in other words if no errors appear then that doesn't mean the the hardware is OK, it just means no faults were found. My recommendation would be to take the machien to your local Apple Store or AASP to be thoroughly tested.
BTW, you could also restart in Safe Mode , this will clear some caches however I don't think this will help based on your desciption. -
My Imac does not start anymore.
==> What I have already done:
1) I tried with the tigger dvd to reinstall. It didn't succeed.
2) Via the single mode, when starting I got the message "disk0s2: I/0 error" several times. After that I got "Root device is mounted read-only"
3) Nevertheless, I tried the "fsck -yf" function. After checking "Journal HFS Plus volume", "extends overflow file", "catalog file"... and invalid record count
==> /dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8
Can someone advices me? I red on the internet I could reformat the disk... loosing all the data I didn't backed up. How am I suppose to reformat?
Thanks in advance,

Restart the computer while holding down your mouse button which if you hold it down long enough (5 minutes at most) should eject the disk
If the disk still doesn't come out at that point then you need hardware evaluation;
contact Apple, contact an Apple Authorized Service Provider, or make an appointment with an Apple Retail Store. -
HT1751 imac does not start becouse cd i burn fast need help
imac does not start becouse cd i burn fast need help
andres:
Running Repair Disk from your install disk as suggested by neuroanatomist is the best first step. I have outlined the procedure in detail below, with suggestions for what to do if DU reports errors it cannot repair:
Repair Disk
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
What’s a kernel panic may help you identify the black screen you saw earlier. If it does, post back and let us know.
Good luck.

Please help me, my Imac does not start and make a terrible noise like an alert when try to start ,the Imac keep a grey screen when try to start and keep there.
Sounds like it is time to take it to an Apple Store or AASP to be serviced. You can also try troubleshooting using Apple's Gray screen appears during startup instructions.

My iMac does not start.
My iMac does not start. When I turn it on, it stays loading in the half and doesn't continue. Some days before I had updated my iMac to Yosemite 10.10. Everything was ok but yesterday I decided tu reboot it and when it was turning on this happened, it kept stuck at the middle of the bar. I have the latest model of MacBook Air '13.
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -
My imac does not start up. It shows a white page with apple sign .
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys. -
My iMac does not start up as usual. I now get a ' start up disk is full. You need to make space available on your start up disk by deleting files' message.
I am able to key my log on password however I just get the purple galaxy screen with no desktop.
If I try to use the keyboard I get a tone when pressing the keys.
Has worked perfectly well up until I got this dusk full message.
Can anyone help please. ThanksYour going to have to follow the Data Recovery Efforts page here to be able to access your drive and remove files without booting the computer.
You can't open the iMac so you will need OS X booted from a external drive or via Firewire Target Disk Mode using another Mac.

I would concentrate on Movies as this is a big source of large files to free up room.

IPhoto does not start to update after my iMac was updated to OS X Yosemite.
iPhoto has been "paused" after my iMac was updated to OS X Yosemite. iPhoto does not start to update when I click "UPDATE" in App Store "Updates". The circle on the left top corner just keep circling. Do you know how to fix this problem? I cannot download my photos to iPhoto without updating it.
Thank you LarryHN,
I could not follow what you have explained to me as I struggled to find iPhoto 9.6. Anyway, while I was struggling, I managed to update iPhoto somehow. Finally, I can use iPhoto!
Thank you very much for your quick response.

Imac 20" intel Leopard black screen, does not start up
Imac 20" intel Leopard black screen, does not start up,
yestarday i put my imac aluminium in sleep, when i wake up this morning the computer did not start up from sleep and also did not start up from the power button back, i try several times and nothing, i hear the sound of the start up but i remain with a black screen. What can be the cause? The video , maybe? I did not install any hardware lately on it.
note: i have a wireless keyboard & mouse
Message was edited by: mindsoulNot running Leopard (Panther), but I have a similar problem on my 24" iMac. Computer was working fine last night (I shut it down) and when I went to boot up this morning the computer is stuck on a black screen.
The boot up sound is initiated but nothing after that. The power light stays at full brightness, if I touch the power button the light blinks and then after a while it goes out. A full reset does nothing. I've tried reseting my PRAM, which works because I hear the start up sound twice, but no change to the black screen.
