My iMac turns on but nothing appears on screen?

I just bought an iMac G5 that from someone I know and he told me something was wrong with it. When I turn it on I hear the chime, the light on the front turns on, the fan turns on and I hear disks spinning which sounds like the superdrive. I took it apart thinking it had to do with the motherboard because he said thats what it was and the lights on the motherboard turn on also. What could the problem be?

You really need to get the install discs from the previous owner, or you can get them from Apple, but you should have them handy. You can try booting from the Leopard disc and using Disk Utility to verufy/repair the hard drive.

My one month old laptop turns on but nothing appears on screen...help

MMy laptop turns on but nothing appears on the black screen

Try to launch your Mac in Safe mode by taking these steps:
- Click on the Apple sign() at the upper left corner of the Desktop, select 'Shut down' from a drop-down menu;
- Wait until your computer turns off, then press the Power button(⌽);
- Immediately after you hear the startup tone, press and hold the Shift(⇧) key. It should be held as soon as possible after the startup tone, but not before the tone;
- Release the Shift(⇧) key when you see a grey Apple sign() and the progress bar below;
This will force the system to perform several maintenance routines and load essential system software.
Once you've seen the Desktop
- Open Disk Utility application:
1. Click on Finder at the bottom of your Desktop;
2. Select Applications folder from Finder's left sidebar and then open Utilities folder (or press Command(⌘)-Shift(⇧)-U), double-click on Disk Utility icon;
- Choose your main hard drive from the left sidebar ('Macintosh HD', usually);
- Click on 'Verify Disc' at the bottom right corner, your Mac will perform a diagnostic test. Click on 'Repair Disk' if prompted to fix problems, or follow instructions given on the Disk Utility window;
- Once the routine finished, click on ""Verify Disc Permissions"", after it's done, click on 'Repair Disc Permissions';
Wait until it will finish and restart your mac

Computer turns on but nothing appears on the screen

Hi,
I have had this desktop computer for about 2 years. I usually use it almost daily and turn it off at the end of the day. Every few months or so the computer would turn on but nothing would appear on the screen. I would have to hold the power button to turn it off then turn in on a couple times or wait until the next day and the computer would turn on and everything would appear on the screen and work perfectly. Last week, the computer once again turned on but nothing appeared on the screen, except this time, after a week, the computer will now turn on except there is still nothing appearing on the screen. I no longer hear the fans running, however, I hear everything else running as normal. I have unplugged and re-plugged in all the cords multiple times and still, nothing.
Please help! Thank you.

Macbook turns on, but nothing on the screen

I had my macbook pro last september for my birthday, and until last night it had been working properly. but just tonight it won't start up! when i held the power button, the screen stays black although there is this normal sound when mbp's starting. I blind my way and click randomly (hoping to choose the username like i used to) and then the screen's all white-and-gray thing. Any idea why, and how, to fix this? also how much would it cost? thanks

nothing, my mouse just stops at the edge of my screen. but i have it mirrored. when i turn mirror off then my mouse goes of the screen but nothing happens on the display. i am going to take it in to the store tonight and see if they can send it back and fix it.
thanks

17inch iMac turns on but nothing happens but boot up sound

hi my late 2006 17" iMac goes to a blank screen when turnt on and does nothing else but make start up sound, could the logic board be broken or is it something else?

Probably, you need to take it in though to find out how much. The computer is 6+ years old, it may simply be time to be replaced.

I follow the instructions of swiping up from the bottom for the control panel, but nothing appears. What am I doing wrong or what do I need to be turned on or off?

I can on mine.
For anyone having this issue, take your device out of the case and try it naked before trying a reset, restore or Genius Bar appointment.

Ok, tried message boards everywhere to try and figure this out before having to post a question. Have a 21.5" iMac running Snow Leopard 10.6.8. After updates no wireless capability for ipad or laptop, imac connects fine but nothing else.No widgets work.

Your post is pretty lengthy and I have to admit I didn't read it all. Please try restarting in Safe Mode, if that doesn't work please do both a SMC and PRAM reset. These may take 2-3 attempts.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
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. You must press this key combination 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.

I am having trouble syncing photos with lightroom mobile. Lightroom (on computer) tells me that it's syncing but nothing appears on my I pad. Any comments?

however when I try to sync my older ipod with it and upload some new music to it, Itunes keeps telling me that all the previous songs will be erased
Yes, that's correct. If you don't have the songs that are currently on your iPod also in your new iTunes installation, they will be erased from the iPod if you sync it. Best to start afresh by first transferring all the music on your iPod back to your new computer/iTunes library.
For iTunes version 7 or later, then you can transfer purchased iTunes store music from the iPod to an authorized computer by using the "file/transfer purchases from iPod" menu. Note that the maximum of 5 authorized computers applies here.
Find out how to do that here.
How to copy iTunes purchases from an iPod or iPhone to a computer.
For all other non purchased content (your own CDs etc), check out the instructions/suggestions here.
Music from iPod to computer (using option 2). This a manual method using "hidden folders" and although it works, it is a little more involved than other methods.
Much easier ways are to use one of the many 3rd party programs that copy music from the iPod to the computer.
One of the most recommended is Yamipod. This is a free program that transfers music from iPod back to the computer. However, it does not transfer playcounts/ratings etc.
Other free programs are Pod Player, SharePod and Floola.
If you want to recover just the structure of playlists from the iPod (and not the actual song files themselves), there's iRepo for Windows. which I understand has this feature along with all the standard features for these programs.
iPodRip also has the feature enabling you to reconstruct playlists.
There is also CopyTrans. This does preserve ratings/playcounts etc if those are important to you but this program is not free. It also supports video transfer.
Once all the music is safely back in your new iTunes library, you can sync your iPod as normal.

Hmmm, assuming both video cards aren't bad, then it must be a logic board problem.

imac turns on but screen stays black ? i can hear it operating ...

Hope this helps:
As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a

GoLive running but wont appear on screen problem

I have a weird problem running Adobe GoLive (version 8) on Windows 7 - the program runs but wont appear on screen. I don't get this issue with any other
program and until this happened a few days ago the program worked fine on Windows 7.
When it's started, the 'title box' with logo and version number etc appears on screen and the icon appears on the taskbar, but no program appears on
screen. It doesn't matter how many times I click on this, it wont appear on screen.   If I hit Alt-Ctrl-Del and bring up Task Manager I can see it's
running in the Applications tab and I can also see it's process running on the processes tab too.
I thought maybe it had gone 'off screen' so I used all the Windows 7 tips on how to bring progs back on screen but nothing works. Interestingly, when I hover
over it's icon on the taskbar, and hold shift whilst clicking it to try to bring up the old-style maximise and minimise options, nothing appears -
although this works with every other application.
I use two screens, so I tried changing the display to use just one - makes no difference.
I then uninstalled GoLive, rebooted and installed it again - makes no difference.
Any idea why this would happen?

Make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
     User/Home()/Library/Caches/com.apple.iPhoto folder.
Click to view full size
3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
NOTE: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.

I came home and attempted to power on my iPad2. I can see the backlight but nothing on the screen. When I try to reset by pushing the off button and the power button at the same time I can sometimes see the characters briefly but the screen has lines. Can someone tell me if there is anything else I can do before a trip to the repair shop?
Will

If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.
