Lines Come Up on Screen When I Turn Up Brightness

Whenever I am outside i can't see the screen because when I turn the brightness past 50% lines will appear and I won't be able to access anything. Does any one have a solution?

Hi jtbvincent,
Thanks for visiting Apple Support Communities.
It sounds like you are seeing lines on your iPhone display when the brightness is turned up, and I know that must be disconcerting. I have a few steps to suggest that can help resolve or isolate the behavior.
First, restart your iPhone:
How to restart
Press and hold the Sleep/Wake button on the top of your device until the red slider appears. Then drag the slider to turn your device completely off.
After the device turns off, press and hold the Sleep/Wake button again until you see the Apple logo.
You can find the full article with these steps here:
Turn your iOS device off and on (restart) and reset
If the lines are still there after you restart the iPhone, I recommend that you back it up and restore it using iTunes:
Back up and restore your iPhone, iPad, or iPod touch with iCloud or iTunes
Use iTunes to restore your iOS device to factory settings
All the best,
Jeremy

When i unplugg my ipod lines appear across the screen and wont turn on how come?

Is it working properly when it is connected to power?

Please clarify... Does the screen look "normal" (and is it turned "on") when connected? When you disconnect it, "lines appear across the screen"? If it "wont turn on," how are there lines (or anything) appearing on the screen?

My ipod comes up with a green screen when i turn it on. I did once eject it safely like a flash drive instead of through itunes. What exactly is wrong with it and can it be fixed?

If you have AppleCare and/or iPod Nano is still under warranty, give them a call. If not, take the computer to your local Apple Store or AASP. The staff will tell you what is wrong w/it and let you know if it can be fixed after it is examined.

My iPad 2 randomly had a line going down the screen when I switched it on today, does anyone know why this is or how to get rid of it ?

White screen when I turn the Satellite M50 on

I intermittently just get a white screen when I turn the computer on. Usually the problem is solved by switching the computer off and trying again - but sometimes I get a white screen again.
It seems to be connected to use of external devices - can anyone give me clear instructions about what should/should not be connected when I start and shut down the computer? Or any other suggested solutions?
Thanks

Thanks for your reply/advice - and the tip about Antivir. I used to use AVG and then Norton came as a package with this laptop....will have a re-think when my subscription need renewing.
I have updated the display/graphics driver but am still having the same problem of a white screen at boot-up. On reflection I think it is possibly a loose connection as I have just been a long trip with the laptop - including a fairly bumpy 4 hour bus ride - and I recall having the same problem several months ago which self-corrected after a similar trip (taking it down to a Toshiba ASP who never saw it as they were closed for the week-end and I had to get back to work!). This may sound strange but I took the laptop for a walk yesterday to see if any loose connection would shift and it then booted up on the second attempt rather than the 8th!
I guess I'll have to take it to the ASP - unfortunately it's no longer under warranty.
EDIT:
Problem solved. High temperature caused this issue

Why does my Mac stay on the white screen when I turn it on?

Why does my Mac stay on white screen when I turn it on?

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
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 3
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 4
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 5
Boot in safe mode. Note: If FileVault is enabled on some models, 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 corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
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 6
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 7
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 8
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 9
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. 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 boot 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 10
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.

Why won't my iPad 1 suddenly not rotate the screen when I turn it?

My iPad 1 won't rotate the screen when I turn it. What is wrong?

Hi nugget,
Do you have the Lock Screen switch in the wrong position? It's the switch on the right side just above the volume switch. Try moving it to the opposite position to see what displays on the screen. If the rotate arrow displays, then you are good to go....
Cheers,

TS1388 hello..i am getting a screen when i turn my laptop on theta says OSX utilities....restore, reinstall osx or disk utility....what does this mean

Hello.. I am getting a screen when i turn my laptop on startup says OSX utilities....restore, reinstall osx or disk utility....what does this mean?

Hi, that sounds like it's booting from a Restore partition, but that is only for 10.7 & up, you list 10.6.8 though.
Anyway, hold alt key at bootup, what boot choices are shown?

How come I get 3G when I turn off my LTE?

How come I get 3G when I turn off my LTE but when my friends turn their LTE off they get 4G? I have Verizon as my phone's carrier.

Because you have a Verizon iPhone and when you turn off LTE it falls back to their EVDO network and correctly shows 3G. Your friends either have a T-Mobile or AT&T iPhone and they refer to HSPA+ as "4G".
A Sprint iPhone will behave exactly like yours.

My iphone 4s will not switch to the wide screen when I turn my phone sideways from an upright position, does anyone have any suggestions to get this feature working again? Thanks.

Is there an on or off button for this feature, as the screen on my phone will not switch from upright to the lengthened screen when I turn the phone sideways. My phone is very new, just got it beginning of July of this year (2012). Has this happened to anyone?
Thanks

My ipod just goes to a white screen when i turn it on

my ipod just goes to a white screen when i turn it on

A white screen is one of those symptoms covered here:
iPod touch: Hardware troubleshooting

My ipod touch 4g, has a white spot on the screen when you turn it on, what is that and how do I fix it?

When you turn the ipod on, there is a noticeable white spot on the screen/display. Once all the apps come on you can't see it, but when it starts up you can.

From you descriptionis is hard to tell if it a atain on the outside of the screen or just what. Have you tried cleaning the screeen as said in the users guide:
Cleaning iPod touch
Clean iPod touch immediately if it comes in contact with any contaminants that may cause stains,
such as ink, dyes, makeup, dirt, food, oils, or lotions. To clean iPod touch, disconnect all cables and
turn off iPod touch (press and hold the On/Off button, then slide the onscreen slider). Then use a
soft, slightly damp, lint-free cloth. Avoid getting moisture in openings. Don’t use window cleaners,
household cleaners, compressed air, aerosol sprays, solvents, alcohol, ammonia, or abrasives to
clean iPod touch. Rubbing the screen with an abrasive material may scratch the glass.

Strange screen when I turn on my macbook

When I turn on my macbook (white and nearly 2 years old), I get a grey screen and a large symbol that is a circle with 3 lines radiating from the circle, which floats around my screen like a screen saver. There is also what looks like a green battery at the bottom in the middle of my screen - it is in 3d and a fluorescent green colour.
I can get past this screen is there anything I can do??

HI and Welcome to Apple Discussions,
Make sure the MacBook is connected to the power adapter to a wall socket and charge the battery.
If that isn't the problem...
Try booting from your install disk and run Disk Utility.
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 later) 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. It should say: 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 you can't boot from your install disk, try booting in Safe Mode
