IMac starts with blank screen
Hello,
My iMac has been acting a little weird lately, until last night, when it got much worse. It's a 2009 iMac running Mavericks.
Every so often when I would turn it on, it would give the Apple chime and the screen would never come on, it would remain blank. I would try restarting a couple of times and it would typically fire right up, Apple chime and the screen would come to life. Last night, I was updating iTunes and a couple other things and my iMac restarted. Except that it did the blank screen thing on restart. Now, I can try restarting it for ten minutes before the screen actually comes to life, but when it does, it goes right back to trying to install updates. After the updates are done installing, the computer restarts itself... And the cycle continues.
It's pretty much stuck in a loop of start-update-restart-blank screen. It won't boot up correctly two consecutive times, no matter how many times I try.
Any advice?
Check System Preferences - Startup Disk and see if your internal HD is highlighted. If it is not please click it and then select restart.

IMac starts with fan, screen stays black
When attempting to start my iMac G5 (Ambient Light Sensor), fans come on but screen stays black. A couple minutes later, the fans rev up and run very quickly and loudly. This started happening when:
1. One day the screen showed a green question mark with a message indicating that the computer needed to be restarted in a box
2. Green lines were all across the screen
3. I forced it to shut down by holding down the power button
4. When I attempted to start it back up the fans started but the screen stayed black
5. After a couple of minutes, the fans revved up
This has been happening ever since. One time the computer started to the desktop but everything was frozen. I have reset the PMU, checked the diagnostic LEDs, reset the PRAM-basically everything suggested. Can anyone help? Thanks!Try the suggestions mentioned in the following Articles:

Strongly recommend that you update to OS 10.4.11. Your system info confirms you are still using the basic Tiger OS. -

My imac starts with a white screen, then goes to black with a small white line blinking in the top left corner of the screen. Any ideas? Thanks.
Try starting your iMac with the original DVD that came with the machine then launch disk utility to repair your hard drive.

Issue with blank screen HP G60-447CL Notebook PC
Issue with blank screen HP G60-447CL Notebook PC, I purchased warranty and have had the laptop serviced before for the same exact issue. Same problem has come up again blank screen it has been less than five months this problem was fixed and it has started again: blank screen white, laptop is powered on nothing else happens. Now I cannot reach anyone.
You're very welcome.
I have tried many times to help folks with different drivers and nothing has worked.
I'd say at least a dozen people have posted about this issue, and no one can fix it.
I don't understand it either. -

Solved!
Go to Solution.What lead_org is referring to is commonly known as "re-balling" which involves unsoldering the Southbridge chip from the planar, replacing all (6-700) solder balls with new ones and then re-attaching it under heat/pressure.
This is the place that you need:

I have a problem with my mac, lit with blank screen loading bar and then goes out, I need assistencia on line or contact the Technical Support Service in Argentina
Priscilla,
if your Mac is still in warranty, then you should contact the Argentinian technical support service. If it is out of warranty, then we can try to lend a hand. (We’re just fellow Apple product users here.) -
Worst update ever! On my Vista everything is wrong! Back button never active; If I want open pages as new tab it opens new window; FF starts with blank page instead of Google; No url address shown on status bar when I move mouse arrow on the link etc.. Please Help!
Try the Firefox SafeMode to see how it works there. <br />
''A troubleshooting mode, which disables most Add-ons.'' <br />
''(If you're not using it, switch to the Default Theme.)''
* You can open the Firefox 4.0+ SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />
''Don't select anything right now, just use "Continue in SafeMode."''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
'''''If it is good in the Firefox SafeMode''''', your problem is probably caused by an extension, and you need to figure out which one. <br />

Can not access app store on iphone 5, comes up with blank screen?
click on app store on iphone 5 and it comes up with blank screen , after awhile the section heading at the bottom of the screen such as top charts, updates, search , etc, but the main screen body is still blank. Seems to be trying to connect but can't. Any ideas? Much appreciate it.
Thanks!
CCDo you have a case on the phone? If so, what case? If you do, then try removing the case and see if it works.
If not, then try a reset. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. The phone should reboot. After that, try again. -
Imac starts with a black screen and flashing white light on console
I have a 24" imac, it is white and it is from the first year they used the intel chip. When I power it up I get a black blank screen and then the white light on the lower right side of the console flashes on and off. I hear the disk drive spin (I put the 10.4 install disk in ) and it does nothing. How do I get the disk out. I even tried holding down the mouse button at start up and that doesn't work.
I tried to remedy this myself by resetting pram. I have taken out memory and put it back in. I have been able to get it running twice before by taking out memory and putting it back in but it only worked for a little while and then I turned it off and went to turn it back on and same problem again. Is this a logic board problem or something else. I think I read if it was the logic board the disk drive wouldn't work but I hear it spinning.
Can anyone help me?Hi MacGruff69
That has all the classic signs of unseated, improperly seated or bad RAM.
Laying the iMac face down on a soft towel and reseat the module(s) by pressing real hard on each one with both thumbs, then closing the ejector clips and replacing the cover.
http://support.apple.com/kb/HT1432
Them if the iMac still has the same symptoms, try one module at a time or replace the module(s) with new one(s).

Sometimes my iMac starts up with white lettering acrossthe screen on a black background - when it's switched off for a few seconds it starts up ok. Can anyone tell me why this happens ?
I have read on here that a PRAM reset can cure this problem:
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. -
Qosmio G30-126 - start up problem with blank screen
My laptop was running perfectly untill i suddenly found it booting with the start up sound enable but without any picture appearing on the display untill i got the windows login page at which the picture appeared with its normal perfect resolution.
The operating system is Windows 7 which was working smoothly, with all toshiba drivers installed from more than 3 monthes and the device was normally shut down the time before the problem appeared.
I tried using the recovery disc but the problem is that i cant see any thing! the computer is working but the display is black as if the laptop is completly turned off.
I tried to connect another external LG LCD but it didnt give any results but only a blank screen.
I really need help in this issue as this laptop contains all my work and i depend on it alot.Hi Jeka-??
First, thanks for the reply. Second i think i can fully access the BIOS using F1 but the problem that the screen is totally black. You will ask how do you know that you entered BIOS? the answer is that it do the restart when i press the right combination of keys to save and exit i.e. After pressing F1, i press the end key which supposed to give me a message of save and exit and i press Y so the laptop restarts.
Third, are you sure that this is a defected GPU card? as if there are any possibilities to try before sending the computer to Toshiba service center, i'll be glad to them on my own.
By the way the graphic card works perfectly when the computer log on the windows even with games i.e. the monitor starts to display picture starting from the choosing profile page of windows. The original recovery disk is VISTA Ultimate and i'd like to restore it back instead of the installed windows 7 as a trial but unfortunately i cant see the process as i have to enter some data to continue installation and i cant remeber them to do it blind.
Do you know a method to reinstall the bios update again? as when i try to install it through windows 7 it keeps saying " [Error] BIOS Update is not supported OS. Unsupported OS or service pack is installed " -
My iMac died after 8 years - blank screen, loud fan noise, no way to erase personal info. To recycle should I remove hard drive, and anything else?
Removing the hard drive should suffice. Use Google to find takeapart instruction, using you iMac's processor description in the search.
At eight years old, it is probably a G4 (the "desk lamp" style with an articulated display arm and white hemispherical base). So the search string would be "iMac G4 takeapart." If it turns out to be some other processor, simply substitute that processor (G3 or G5) for "G4."
The HD may not be bad, so you could keep it and connect to a newer Mac to retrieve files using this handy and inexpensive gadget:
