The white screen issue is at least recognised....

....and the solution is not more robust software but the 'fix' we've suggested for ages of rebooting the device!!!!
ROTFL.....

Downgrading to 7.0.1 did not solve the white screen issue.

Hello -
A little background - in early January, with a thesis presentation due, I delayed upgrading to Quicktime 7.0.4 until after the thesis - this was a good idea, because now after upgrading and downgrading again, I've got problems.
I made a video with Final Cut Pro - (assume I can no longer go back and output it again) and have the file as a .mov. Before upgrading, thesis era, I threw it into iDVD and got a DVD.
NOW I need to make more copies of the DVD so I go about re-creating the dvd in iDVD with the exact same files... and the video comes up blank. both in quicktime AND in iDVD.
I downgraded from 7.0.4 to 7.0.1 - but that did not solve the problem completely... sure, I get my audio back now, but the film is entirely white-screen...
I'm under a massive time deadline to make more copies of the DVD and I'm at a loss os what to do! Please help!!
I'm already deleted the receipts, downgraded from 7.0.4 -> 7.0.1... no fix.
tried going back to 7.0.3 from 7.0.1... no fix.
went BACK to 7.0.1 again.... no fix...
HELP!!!! t
thanks

Creative Zen X-fi (with lan) white screen issues

?Hello everyone, So I've been having my zen x-fi for a few months and it has been working excellently...until yesterday when it suddently (after what might have been a lightly hit, I had it in my front pocket and bumped in lightly into some object)...well suddently the screen went white but kind of still something black there (see photo below) <a rel="nofollow" target="_blank" href="http://img40.imageshack.us/img40/666/dscf2249redigerad.jpg"]http://img40.imageshack.us/img40/666/dscf2249redigerad.jpg[/url] I have been looking into troubleshooting about this particular issue, but what is suggested there under the white screen-issue is to reset and update firmware, something I did already first thing after it happened. The thing is that other than the screen being a quaking mess, it seems to otherwise be in working condition, because when I turn it on and push the play button music will still play as before. it's just the screen that is the problem. Any ideas? Best wishes, Babba

Hello there, thank you for your welcome. That is sad info about my music player though, I liked it so much while it was still working. unfortunately im not within the warrant period so I will have to invest in a new one. thank you for your help though. I will look into which creative player is the best one within my price range

Having an intermittent issue where my iMac blanks out on me. On restarting I get bands running down the screen with pixels jumping around, then the white screen of death and nothing... Wouldn't restart all weekend, now fine..? any ideas whats wrong?

Having an intermittent issue where my iMac blanks out on me. On restarting I get several bands running down the screen with pixels jumping around within the bands, then the white screen of death and nothing... This happens intermittently and usually restarts OK. Happened again three days ago and wouldn't restart for two days (again the bands/pixels etc) but now operating fine? Any ideas whats wrong with my iMac and what the solution may be? Also gets very hot from time to time, particularly if I'm playing music/watching youtube/movies for extended periods. Mac is 3.5 years old, running OS X 10.6.8, processor 3.4 GHz i7 memory 8GB 1333 MHz DDR3

If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing. Use 2nd link if not near an Apple Store or aren’t in the US.

My 27" iMac has just creen issue repaired. I restored from my time machine and now the white screen is back and I am unable to access an recovery option. It looks like its no responding to the USB keyboard

My 27" iMac has just come back from the workshop after having a white screen issue repaired. I restored from my time machine and now the white screen is back and I am unable to access an recovery option. It looks like its no responding to the USB ke

Thanks for your reply! I must apologise for the quality of my post. I inadvertently posted it before it was corrected.
I am very disappointed with this iMac. It is only 18 months old and this will be the third visit to the workshop. I had expected more from Apple and from their repair agents. Luckily I have AppleCare.

I have a 13 inch MacBook Pro (2009) & the "White Screen of Death" is present. Need help?

I have a 13 inch MacBook Pro (2009). Recently I bought an extended hard drive because I had used up the memory on my iDisk. As I was running the Time Machine back up on my new extended drive, the battery on my Pro ran out causing it to shut down. Once I hooked up my Pro to the power cord & logged in, the "White Screen of Death" appeared on the home display. Obviously the battery still works, my phone is able to charge along with the extended drive, I am able to adjust the lighting on my keyboard along with adjusting the brightness on my screen, but the "White Screen" remains. I need help in determining the cause of this issue & the steps I'll need to take in order to resolve this. I love my Pro, all my documents, photos & music are on it & the last thing I want to do is kill my wallet by buying a new Pro. So could someone on here please help me? It would be greatly appreciated & I thank you in advance!

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your 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 your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into 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.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot 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.
c. 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
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot 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, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your 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 reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to a Mac Pro tower, not to any other model. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

One solution for the white screen of the dead on

I bought a creative ZEN with the white screen. Then return this to the shop and then another ZEN with with screen of the dead but I found this solution:
http://www.youtube.com/watch?v=a8g0sh7pc54
It is important that the screen turn off, so it is necessarily for example that play some song.
I try all things that they says in this forum but only this is OK.
Hablo espa?ol por si alguno necesita ayuda en este idioma.

because it works for the majority and not the minority doesnt mean its good it means there are some issues which need sorted for individuals.
and my iphone is not jailbroken it has all original apple software on just had to circumvent the system to get it back to a stable working condition before the fantastic update to ios6 and i have also updated 4 devices 2 have had problems and 2 have not so figure that out. Apple should at least have admit there are issues with certain hardware and support there customers as a unhappy customer will allways remember the bad bits and not the good bits and you keep refering to the millions it works for what about the ones that it doesnt or are they not important or is your money better then mine i dont think so some how all i ask for is decent customer service that will resolve my issue but im guessing thats far to hard for you to comprehend and my phone is 2 month out of warranty which is why most of us are here i would think or we would all be at the apple store.

Last night I did an update and now when I turn on my macbook it just goes to the white screen with the apple and stays like that.

Last night I did an update and now when I turn on my macbook it just goes to the white screen with the apple and stays like that. How do I fix this issue?

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 iphone wont open, i even recovered it but to no avail, all it does is go to the white screen with the apple logo then turn off again

Hey everyone,
This morning i took my phone out of the charger and everything was normal however, once i got in the car i looked at my phone and realized it was turned off. I tried turning it on again as well but all it does is going to the start up screen (The white screen with the apple logo) and then it turns off again as well. I also put it on the charger but it does the same thing but repeatedly. So it just goes to the white screen and off again. At last i resorted to recovering my phone even if it meant losing all my data. Slow internet connection meant it took all night but in the morning i recovered and everything and got to the last step ( It told me its finished but i should leave my phone connected to itunes and it will pop up there) but all that popped up was an error screen. It still broken but now sometimes when i try to turn it on the same white screen with the logo comes on with a bar under it. this bar fills up a little then the screen goes black again. Is there any other way i can try to fix this?
P.S. There are no apple stores in my area so i took it to one of the phone stores here and even they said they couldnt do anything about it

Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

What causes the white screen?

It started a few days ago when after leaving my ipod in the car for a few hours, the screen had turned white. No horizontal lines anywhere. No grey stripe down the middle. Just a blank white screen. I could still hear it scroll around and I even selected a song to play. However, shortly thereafter, the entire ipod froze and no amount of resetting did anything.
Once I got home, I plugged it in to itunes, restored it, and voila! It worked poifect. I had my regular black with grey apple screen back, i put music on and it played normally. Unfortunately, the next day it was deja vu. I got back to the car and there's the white screen.
After repeating the itunes restoring process however, it only became worse. Now, it is permanently stuck on the white screen. Restoring does nothing. I tried resetting, but it only gives off two short, loud beeps. In fact, holding any button gives off those beeps.
I have researched this topic for a few hours now and no one seems to know what is wrong. The only answers given are that I should send it into apple if I'm still under warranty (I'm not), or that I should get a new ipod, which is ridiculous. The ipod hasn't been damaged in any way. It's not a cracked or broken screen, or else I would still be able to play music. I did see on one forum that it could possibly be a firmware issue, but doesn't give a solution. Could it have possibly been when I updated the iTunes a few days ago? That's around the time when my problem started.
This ipod has served me so well and I hate to be disappointed with it now. Even if it can't be fixed, I would like to know what's wrong. I could call apple support, but with the answers I've seen online, there's a large probability that I would be paying $30 dollars for someone to tell me there's nothing I can do.
Does anyone have any clue what's wrong?

I am having the same problem. I just got my phone over a month ago and it just started doing this. I talked to an Apple rep last night and since I am still under warranty they will ship me a new one if I use my credit card to secure the transaction. They want to put a 499.99 pending charge on a 99.00 phone. Luckily I will be by a Apple store to exchange it but for now I have a paperweight.
You would think there would be a fix for this instead of having to return it.

HT4623 I downloaded ios7 and initially it was working fine. Now it is flashing from my home screen to the white screen with the black apple every 3-5 seconds. It's so annoying and I can't make it stop! I tried shutting down all the way - nope! HELP!

I downloaded ios7 on my iphone 5 yesterday. All day it worked fine, then last evening it started blinking from the white screen with the black apple to my home screen. Each screen only stays up for 3-5 seconds then switches back. I have tried shutting down and it is still happening! Does anyone know how to fix this issue without having to go into the store?

Your power adapter is OK. If the only place it will not work is in your home, your house wiring and / or the appliances connected to it are likely to be the reason your Mac will not charge.
From Troubleshooting MagSafe adapters:
Identify line noise issues.
Unplug the power adapter from the wall, let it sit for 60 seconds, then plug the adapter back in.
If the adapter works after this 60-second "rest", you most likely have a line noise issue with your power source. You should reset the adapter periodically by repeating this moment of rest. This issue occurs when the AC adapter's "over voltage protection" feature senses ground noise and then turns off the adapter.
Some possible sources of line noise include lights with ballasts, refrigerators, or mini-refrigerators that are on the same electrical circuit as your computer. This behavior may not occur if you plug the power adapter into an uninterruptible power supply (UPS) or plug it into a different circuit.
Unless the adapter continues to exhibit this behavior on a known good outlet, it does not need to be replaced.
Household wiring problems are very common. They can also be very dangerous. Fortunately most problems can be easily fixed by a qualified electrician.

Mac won't go past the white screen and apple logo

My one year old mac won't turn on, it comes up with the white screen with the apple logo, after a few seconds a loading bar comes up and after it finishes loading the mac just turns off. When I turn it back on it just does the same thing. I tried resetting the pram (it even chimed twice) but it still did the same thing. The problem began with the power cord being accidentally unplugged, when I plugged it in and turned on the mac the grey screen came up asking for my password, it then began to load but after about 5 seconds went back to the grey screen. I tried logging in over ten times and after failing turned off the mac, now it's doing the loading thing...
Oh and I don't know if this is relevant but I had a mountain lion update that needed to be done?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your 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 your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. 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
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot 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, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your 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 reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Hello. When I connect my imac Start, as usual, comes the start signal and then the white screen with the load signal then nothing happens. What could be the problem?

Presuming you get the chime, most of your Mac hardware is working and has passed the first part of the power-on self-test.
If the screen comes on, basic graphics is working.
The dark gray Apple is not present inside the Mac -- it must be loaded from a boot device. If the dark gray Apple appears, at least one of your boot devices has some capabilities. The flower petal/gear moves while Darwin is initializing and loading. If it stops immediately, something is terribly wrong.
When the screen turns blue, Mac OS X has loaded and your graphics card transitions to Interrupt-driven operation. LoginWindow task draws the login screen, and Mac OS X is ready for login.
What could be the problem depends on where in the process it stops, and whether the power light is blinking.

White screen issue on Compag

My Compaq is currently displaying only a white screen. The laptop boots up fine and displays fine on an external monitor.
I have taken it apart and reseated the connectors on both the screen and the motherboard with no effect. So I am sure it's not a loose connection.
Before I go and splash out on a new replacement screen, is this an issue that is usually seen when the screen itself is at fault. Could it be the cable? or the connection on the motherboard itself. Is there a way to be certain?
I don't want to buy a new screen and find it's not at fault.
Many thanks!

Hello, @Skyfox
Welcome to the HP Forums.
I see that you have a white screen issue with the notebook. I will try to assist you.
With the steps you've taken and the fact it works correctly with an external, leaves only the display screen as the possible cause. That being said, there is no 100% way to know that it is not a cable causing the issue.
Typical steps for this issue:
Restart notebook
Hard reset notebook
Test with external monitor
Reconnect LCD cables and check all other display cables
Have notebook serviced.
You're at the point of service. This really limits the options, and a display replacement may not correct the issue.
I hope this adds any insight to the choice you need to make next.
Thank you for posting on the HP Forums.
I worked on behalf of HP.

The white screen issue is at least recognised....
