Random light spot on screen

I bought my Macbook Pro in August and have found that especially when viewing a black background, etc. there appears to be a random light spot around the middle of the screen. The light spot on a black background appears to be grey.

I had the same problem with my 10 month old MBP. There was a spot that looked light on a white background, and appeared darker on a dark background. I took it to an apple store genius bar about two weeks ago only to be told by the "genius" that it was caused by a smudge of oil from my fingers on the keyboard contacting the screen while it was closed. I told him that I have a microfiber cloth I purchased in that very store on the suggestion of one of their salespersons to avoid that problem. Here is the kicker, he then told me that using the microfiber cloth to cover my keyboard while the MBP was closed would cause MORE finger oils to be deposited on the screen. This is interesting considering that the surface of the microfiber that touches the display while the machine is closed never comes into contact with my fingers. Even though I was pretty angry, I didn't fight it and just left the store amazed that this kid qualified as a "genius."
New years eve I was driving home past another apple store and had some extra time so I decided to take it in and see if this apple store had idiots at their genius bar too. I was pleasantly surprised when the genius changed the desktop to white and said "yeah I see what you are talking about, you need an new display" and subsequently started writing the work order for it. So they are presently putting a new display on my machine. Thank goodness that the idiot at the genius bar was an isolated occurrence, and thank goodness I decided to try once more before my warranty dies.

Light spot on iphone 6 screen

Hello Friends,
I just got my new iphone 6 from ATT. After setting it up i found there is a white light (spot) which is brighter than the rest of the display. This light is visible on all light colors and not on dark colors. Let me know if this needs to be exchanged from Apple.
Regards,
Sathish.

Left end of screen. The light is pretty bright. For me it show up all the times under white and any light color background.

Why am I getting faint random ink spots on my inkjet prints from indd files?

I am running OS10.4 with CS2 on an Intel Imac with 2 GB ram and an Epson C88 printer. I made files in Photoshop and did a layout of the files with indesign. The psd and tif files on Photoshop print nicely without the faint random ink spots. The indd files which contain multiples of the psd and tif files print with the faint random ink spots. Please help. Thanks.
Alan

If the spots aren't identical, its more likely that your printer heads need to be cleaned. If they
i were
identical, here's what I was thinking about the percentage:
Suppose your Photoshop image has a dark subject against a light background, and there were some very small dark spots in the background that you missed or didn't want to remove. If you print it from Photoshop at 100%, the spots might not be large enough to trigger the printer to deposit some ink droplets on the page. But, if you enlarge the image in InDesign, it may make the spots large enough to show on the page.
Mind you, that's just a shot in the dark. It could be something totally unrelated.

I accidentally dropped my friend's macbook air that was in a book bag. The keyboard is working because I can see the light but the screen is black and it won't turn off. How should I fix this? Please Help ME!!
I tried to turn it off and it didn't work... and I held on to the shift key too and it still doesn't work..
Please help me..

Accidental damage is not covered under Apple warranty. And it seems there is much accidental damage. Only a Genius Bar tech looking at it can tell how much it will cost to repair.
Cost to repair will be high, I suspect (though Genius Bar will confirm/deny.
There is no gentle way to say this sir/ma'am ... someone will need to pay for your friend's MBA repairs.

Can you start Firefox in [[Safe mode]] ?
You can also do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.

Camera video preview - Random crashes and green screens

Hello everyone,
I am currently working on a Windows Phone 8.1 app and I need to preview video from the phone's back camera. For quite some time I've been struggling with random crashes and green screens. When these green screens appear, all camera apps become affected and
the device needs to be restarted. Occasionally the phone freezes and only recovers after battery removal. I test the app on my Lumia 620.
After some web search, I found references to the same problem by many users/developers of different apps. I'm really frustrated as I've tried many possible solutions with no avail.
Here is part of my code:
//in App.xaml.cs:
MediaCaptureInitializationSettings settings;
public static MediaCapture captureMgr;
public static bool UnableToInitializeCamera = false;
public async Task InitializeVideoCapture()
DeviceInformation backWebcam = await GetCameraDeviceInfoAsync(Windows.Devices.Enumeration.Panel.Back);
if(captureMgr!=null) captureMgr.Dispose();
captureMgr = new MediaCapture();
settings = new MediaCaptureInitializationSettings();
settings.StreamingCaptureMode = StreamingCaptureMode.Video;
settings.PhotoCaptureSource = PhotoCaptureSource.VideoPreview;
settings.AudioDeviceId = "";
if (backWebcam != null)
settings.VideoDeviceId = backWebcam.Id;
else
var _messageDialog = new MessageDialog("Back panel camera not found");
_messageDialog.Commands.Add(new UICommand("OK"));
_messageDialog.ShowAsync();
try
await captureMgr.InitializeAsync(settings);
captureMgr.SetPreviewRotation(VideoRotation.Clockwise90Degrees);
UnableToInitializeCamera = false;
catch
UnableToInitializeCamera = true;
Debug.WriteLine("HANDLED EXCEPTION: camera could not be initialized");
var _messageDialog = new MessageDialog("Unable to initialize camera");
_messageDialog.Commands.Add(new UICommand("OK"));
_messageDialog.ShowAsync();
protected override async void OnLaunched(LaunchActivatedEventArgs e)
//.... other app initialization code
await InitializeVideoCapture();
Window.Current.Activate();
private async void OnResuming(object sender, object e)
AppIsResuming = true;
FinishedCameraInitialize = false;
await Task.Delay(TimeSpan.FromSeconds(0.5));//this makes crashes less frequent
await InitializeVideoCapture();
FinishedCameraInitialize = true;
if(WasPreviewingCamera)
WasPreviewingCamera = false; //the following line allows time for SetupPage._captureElement to be assigned before video preview starts while (!SetupPage.CaptureElementSourceAssigned) await Task.Delay(TimeSpan.FromMilliseconds(1));
SetupPage.CaptureElementSourceAssigned = false;
try
Debug.WriteLine("trying to restart video preview");
await captureMgr.StartPreviewAsync();
SetupPage.PreviewingCamera = true;
catch
Debug.WriteLine("HANDLED EXCEPTION: unable to start previewing");
SetupPage.PreviewingCamera = false;
GC.Collect();
AppIsResuming = false;
private async void OnSuspending(object sender, SuspendingEventArgs e)
var deferral = e.SuspendingOperation.GetDeferral();
while (AppIsResuming) await Task.Delay(TimeSpan.FromMilliseconds(1));//prevents crash when app is suspended right after it is resumed
await CleanupCaptureResources();
TimeOfLastSuspend = DateTime.Now;
FinishedCameraInitialize = false;
GC.Collect();
deferral.Complete();
public async Task CleanupCaptureResources()
if (SetupPage.PreviewingCamera)
await captureMgr.StopPreviewAsync();
WasPreviewingCamera = true;
SetupPage.PreviewingCamera = false;
else WasPreviewingCamera = false;
if (captureMgr != null) captureMgr.Dispose();
//in SetupPage.xaml.cs
void OnSuspending(object sender, Windows.ApplicationModel.SuspendingEventArgs e)
var deferral = e.SuspendingOperation.GetDeferral();
_captureElement.Source = null;
CaptureElementSourceAssigned = false;
GC.Collect();
deferral.Complete();
private async void OnResuming(object sender, object e)
ProgressRing2.Visibility = Visibility.Visible;
ProgressRing2.IsActive = true;
while (!App.FinishedCameraInitialize) await Task.Delay(TimeSpan.FromMilliseconds(1));
App.FinishedCameraInitialize = false;
captureElement.Source = App.captureMgr;
CaptureElementSourceAssigned = true;
GC.Collect();
ProgressRing2.Visibility = Visibility.Collapsed;
ProgressRing2.IsActive = false;
Any help towards a solution will be greatly appreciated.
Thank you

I will also advice that you start by following the
Windows Store app sample.
Is this a Windows Phone app?
The crash/green screen only manifests itself when I suspend my app and switch to the default camera app (could be any other camera app perhaps). It happens roughly 1 out of 8 times. That's why I posted the suspension and resuming handlers, which I wrote
according to the msdn instructions.
I found
this page with a sample that demonstrates the MediaCapture API for Windows Phone. Some developers have reported problems similar as mine. Has Microsoft dealt with this issue?
I've spent quite a few weeks trying to investigate this problem, without actually knowing if it is my code that needs to be debugged. That's why I'm asking if other developers are facing similar problems.
Thank you
Edit: It seems that the crash/green screen can appear when suspending/switching to any app (regardless if it uses the camera or not). Also, all works fine when the app is running on the debugger.

Black spot on screen mac book air

Black spot on screen. I stepped on the edge of it. It looks ink puddle

I stepped on the edge of it.
Yes, when it looks like blue and purple ink spot/spill that means you destroyed the LCD display,
it cannot be repaired, the monitor assy. must be replaced.
Contact Apple for appt. to replace your monitor.

My mac has randomly enlarged everything on screen, how do I restore it to normal?

my mac has randomly enlarged everything on screen, how do I restore it to normal?
I have tried just simply zooming out but it doesn't change the size of everything, I have also tried restarting the computer which hasn't worked either.

Turn off Zoom from the Universal Access and Keyboard & Mouse panes of System Preferences.

Have just upgraded to Lion. In all applications a box now appears that encloses topics, etc on the screen. It is a problem as it also randomly moves around the screen. Have no idea what the purpose is and want to get rid of it. Scroll does not work.

Just upgraded to Lion. Scroll does not respond. Have tried altering preferences. Will not fix. In all applications, including this page, a box appears and seems to randomly move around the screen, resting wherever I begin to work. How can I turn this off and get scroll to work normally?

Have a look at System Preferences, Accessibility, VoiceOver.

How do I keep my cursor from flying to a random corner of the screen when I lift the mouse?

My cursor contantly jumps to a random corner of the screen when I do a large movement or lift the mouse. Can I fix this?

You can first do a SMC and PRAM reset. You can also restart in Safe Mode to reset some caches. However first I would look at the preferences for the mouse in System Preferences.
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.
Roger
