Sometimes my iMac starts with white lettering across the screen on a black ground and after switching off for a few seconds starts on ok ! Any ideas
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.

The ipod will show flashing white lines across the screen, going down, it then does somthing where the screen will dim down but its not like when the backlight goes on and its about to lock. It dims the background of your ipod and the icons and letters kind of all look defined. Then the ipod gets all pixelized and it has big boxes on pixels and its all differnt colors like purples and greens, red, etc. then it turns right off and restarts itself less than 5 seconds later. These things happen really fast but when it does it's really weird. It first happened 3 times in a row, Its still continuing to happen but i can manually turn off my ipod by holding the lock button down and not even 30 seconds later it's like its possessed and it turns on by itself. I talked to somone on appel and they told me to back it up and restore it. I restored it and as soon as the process ended and tuirned on like a brand new ipod and like clockwork the glitch happened instantly. It did it a couple of times throughout the night and i kept having to watch it so i can keep turning it off manually because it continues to turn on by itself. I talked to 3 different people on Apple Support and they couldnt even find an answer for me. It's so weird.
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

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

Also,
If you restored to factory settings/new iPod via iTunes (Not via Settings>General>Reset>Erase all Content and Setting) and still have the problem that indicates a hardware problem.
Make an appointment at the Genius Bar of an Apple store..

Probably a failure of the LCD panel. You can check this by plugging in an external monitor. If the white stripe isn't there, it's the panel. -

Apple will exchange your iPod for a refurbished one for $99 for 16 GB 5G and $149 for the other 5Gs. They do not fix yours.

What could be wrong with my iMac? When switched on the screen displays the apple logo with a busy bar at the bottom of the screen. This displays the progress of the computer trying to do something. To fill the bar takes about 30 mins and then switches off
Which OS X is installed?

Suddenly, my Classic ipod got two narrow, black lines runnings horizontally across the screen. Will thes eventually go away or is the screen damaged?
Thanks!You can work through the remaining five 5 R's of troubleshooting.

It might also be a good idea to let the iPod's battery fully drain. Then charge it back up and restore it once more in iTunes.
Otherwise, it's likely a hardware issue with the iPod's LCD display, meaning you'll need to take or send your iPod in for service either via Apple or a third party repair service. Here is Apple's repair pricing.
http://www.apple.com/support/ipod/service/prices/
Note that they don't actually repair the device, but exchange it for one of the same generation, model, and capacity. A third party service will actually replace the damage part for a little less. Google "iPod screen repair" and you should get a number of results to work with.

least ten seconds, until the Apple logo appears.

I want to change the white letters on the tool bars to black-how?
I am elderly and having white letters on a pale grey background on the toolbar strains my eyes. I would like to change the letter color to black, but cannot find a way to do this.
If you have a new email address then create a new mail account for that email address.
In Thunderbird:
File > New > select 'Existing mail account'
or
Menu Icon > New Messages > select 'Existing mail account'
when creating the mail account, make sure you select the type of mail account you require...Pop or IMAP
more info here:
https://support.mozilla.org/en-US/kb/automatic-account-configuration?esab=a&s=new+mail+account&r=0&as=s
If you have the same email address but want to change the server it uses.
If you currently have an IMAP mail account and you are wanting to close it, you would need to get a copy of any emails into Local Folders first.
Synchronise the folder for offline use, then in offline mode get a copy of emails into Local Folders.
If you have a pop mail account, the emails are already on your computer.
To change the server, but not email address:
you will need to know your server settings first.
Thenright click on mail account name in Folder Pane and select 'Settings'
select the Server sEttings for the account
or Tools > Account Settings > Server Settings for the account
Change as necessary
server name:
Port:
Connection Security:
In the left Pane, at the bottom Select 'Outgoing Server (SMTP)
click on 'Add'
create the new outgoing server entering the server details
username: = full email address
then click on OK
then select the account in the left Pane
at the bottom on the right side:
Outgoing Server (SMTP)
click on the drop down selectionand locate the new outgoing server.
then click on OK to save changes. -
2009 i7 iMac Screen Stuck at Black during and after Startup
Have had this iMac since early March 2010, its been great and my favorite apple product to date. 4 Weeks ago I left to Europe and left my computer OFF and with the power cord not plugged into the wall. I came back, plugged it all back in and turned it on...everything worked fine, surfing the net and CS:S i leave again last week to Denver and left the computer in the same way, OFF and unplugged. I came back today turned it on, i hear the fans, I hear the computer starting up, my external hdd gets power but my logitech mouse would not get power through USB. Ten minutes later my screen is still black, no flickering no nothing just black. I then went ahead and turned it off via power button and disconnected all peripherals mentioned earlier and still nothing. Called applecare they made me do some power cycle thing and still nothing, now I have a Genius appointment tomorrow afternoon....any ideas? Could the screen just have died or some connection on the board burned out? Thanks in advanced!

Try Resetting the PRAM
If that doesn't make a difference, try Resetting the SMC
iMac since early March 2010
Should still be under the one year limited warranty.

This happens when I'm literally DOING something, like typing or moving my mouse. When I'm in no way not doing anything on my computer. Any thoughts on why?
Specs: Version 10.6.7, 2.13GHz Intel Core 2 Duo, 4 GB.This might sound silly, but I'd check your Exposé settings: System Preferences > Exposé & Spaces > Exposé
It's just possible you've set up a hot corner to put your computer into sleep mode when the mouse wanders in that direction.

Colored and white lines across iPad screen
Ok so I got home from work and I pulled my iPad out of my laptop bag and I noticed that when I turn it on there are like these colored lines and also this big white bar across the screen. Why are those things there?
http://www.flickr.com/photos/53513466@N03/4946889384/My son bought the original ipad in November 2010, it is now only a few weeks out of warranty. He turned it on tonight and as other people have mentioned on this forum the ipad now has coloured lines across the screen. I called customer services and I must say i am extrememly disappointed with the response I got. They offered me a replacement for £260..... no other explanation other than it may be a hardware problem. After paying £600 for the original ipad only just over a year ago I would expect better from Apple. Myself, my husband and my three children all have iphones and other apple products but I must say if this is the support you get then I would consider other options in the future. Very disappointing....... If anyone else other than a customer service agent who reads from a script can help then please get in touch. Thanks

My macbook pro keeps freezing with vertical lines on the screen
I have a 2010 macbook pro that has worked wonderfully until now. As of late it keeps freezing with vertical lines across the screen. To me this indicates a hardware problem, but I ran a diagnostic (restarted while holding D) and it didn't find any errors. It seems that it happens when I move or bump my macbook, leading me to think it may possibly be a disk problem, but I'm not sure how to check this. Anybody else ever have this problem or could suggest a fix for it?
You can try a pram reset, which might help with the display, but the bumoing thing is what concerns me.
PRAM reset:
Power down, power back up and hold the following keys before the start up chime.
option, command, P, R,(no commas) continue to hold these keys till you hear the start up chime 2 times then release.
Reboot see if this helps, the bumping part scares me.
Hope this helps
