Hi shashwat315.
Welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
If you have a screen protector on the screen, try removing it and see if the white disappears, if however this does not help, then you are likely looking at hardware, in this case you would be best contact Sony Mobile Customer Care to advise.

White patches appearing on the screen after some time

I have bought an iMac recently. And for some days white patches like something occurring on my screen after sometime when I opens it. And the patches are there after closing it till sometime. So what can i do now? PLEASE help me .

That sounds like condensation forming between the display and front glass panel.
If you live in an area with high humidity, then might help to run a fan or dehumidifier to help reduce the moisture in the air.
It also might help to leave the iMac on and running for a day or so to compleatly dry out the trapped moisture.
If those steps do not help, then you may want to take the iMac to your local Apple Store or AASP and have them clean between the display and front glass panel.

Mountain lion finder window white patches

This is difficult to describe, I'll try and do a screen grab next time it happens, but simply, occasionally, when I wake up my iMac there are big areas of random white patches on the desktop ... it's totally corrupt and I have to bring up the 'Force Quit' dialogue and 'Relainch' finder which clears it so no big deal - I'm more concerned that it might be pointing to a more profound problem.

OK I couldn't get a screen grab (well the phenominon didn't appear in the grab) but here's a photograph, it is a small area of white in the top corner of the screen, often it takes more of the space in random rectangular 'patches' ... any thoughts welcome.

White patch

This morning, I opened my Macbook and there was a white spot where the screen just
appeared to stop at. It has been getting bigger all day, especially when I try to adjust the screen tilt. Now, it encompasses about the bottom right quarter of the display. It almost looks like an index card (white with vertical blue and pinkish/red stripes.) There is no display where the screen starts. I am using a white 13" 2007 macbook that is running on Leopard 10.5.5. I am not in a position to go to an apple store currently, so what should I do and what is up with my screen.

I am having the same problem on my 21" Cinema Display but my white patch is in the top right hand corner which is quite big about 4cm and now one is starting in the right top corner which is small. My daughters boyfriend who knows a bit about mac computers said it seems to be a heat problem and because it is still under warranty to take it back to the store I purchased it from which I am going to do, I will let you know what they say. The screen has not been exposed to constant sunlight. I will keep you posted.

How do I back up my MacBook Pro from an external hard drive if my macbook won't boot up from the white start up screen? HELP!

I went to the Genius Bar a week ago, and the guy helping me there was nice enough to help me save some money by telling me I could replace the bad hard drive my MacBook Pro had by myself. I bought everything I needed (hard drive, screws, external hard drive) and my computer won't boot past the white start up screen. It doesn't even show the Apple sign at the start up screen. How do I back up my computer so I can save all my music, school files, etc.? Could really use someone's advice on what to do! Thanks!

Ok, to be sure I understand what's going on. You were able to boot the Macbook from the existing "damaged" internal drive, and it has been backed up to the internal.
If that is correct, your internal drive is working. Just to be sure, try booting with the R key down. Then run Disk Utility to repair the internal drive. That drive may in fact be useable.
You should be aware that you cannot boot the MBP from a Time Machine back up.
Please post back so I am sure I am understanding the situation.

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle. I have tried various commands but to no avail. does anybody have any advice?

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 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 you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
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, or if a firmware password is set, or if the startup volume is a Fusion Drive or 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.

CRASH REPORT
Product: Adobe Photoshop CC
Application running on:
Apple iMac 3.5GHz late 2013 / Mavericks 10.9.2
Application crashes without warning. Symptom: Drop down boxes go blank white (I shot screen captures of blank drop down boxes) and application stops working, actions for appox. 10 minutes preceding crash are lost. Force Quit required to quit unresponsive / frozen application and then Restart of Adobe Photoshop CC
Crash Frequency: Three time in this work day, 5.6.14 Once a day sporadically (approximately 10 times) in past two weeks.
Other applications running at time of crashes: Adobe Bridge - NOT effected. Computer was on line with no browsers open.
Otherwise computer continued to operate normally.
I have been using Adobe Photoshop CC for approximately two months.

Thanks, Chris,
I hope that this is the solution.
re: "And a crash report without an actual crash report (a long, detailed text document available from the crash report dialog), is not all that useful" :
I did in deed submit a homemade crash report.
I would have submitted "an actual Crash Report " and sooner, but: When this event occurs. there are NO dialog boxes. All frozen / blank. No possibility of "actual crash report" !
Thank you!

Appearence of white patches when application is launched by Acrobat 8.0

Hi All,
When I launch an application(scanner) from acrobat 8.0(createPDF->From Scanner) I can see some white patches on the application but this doesn't happens when scanner is launched as standalone application.
Can any one faced this problem?
Thanks in advance.

You print to the Adobe PDF printer using the PDF Port. That is how AcroTray notes the file that is produced and starts Distiller. Printing to file with the Adobe PDF printer and then opening in Distiller is the base line of PDF creation that all other methods depend on. If this one does not work, then you have a problem. If you can print to file, then open the file in Distiller to get a PDF, then it is typically AcroTray that is the problem. Sometimes you have to kill AcroTray and then restart it.
It sounds like you may need to do a repair on the Acrobat installation. That is done from the control panel. In XP it is in the Add-Remove Programs. It was moved to another icon name in VISTA. It seems MS and Adobe both like to move things around and rename them!
You say you get an error when you check the print-to-file button, or at least that is what I think you said. Is that correct, or were you able to get a PDF with Distiller? Some folks have also found the need to do a repair after a Windows update. You might also want to look at the subversion you have. AA8 is up to either 8.1.7 or 8.2. You can check in the help file and then download any updates from Adobe.com>downloads>updates>Windows Acrobat. Be sure you install any updates in order, they are no cummulative unless it specifically says so.

Watching Movies: iPod to TV- black and white and split screen. Help?

I have this cable: http://www.radioshack.com/product/index.jsp?productId=2994604
As you can see, the chord colors on that cable are red, green, and white. The places where the chords go in on my DVD player are yellow, red, and white. As you can tell, they don't go up. I connected them so the audio works fine, but the movie shows up ONLY in black and white, and the screen is split right down the middle. On my iPod, the 'Video Setting' do not fix this. I also have the iPod Classic 80 GB, for reference.
Help?

A white patch has appeared on my Sony Bravia LCD TV.

A white patch has appeared on my Sony Bravia LCD TV. The patch is slowly growing in size and obstructing the picture. Unable to see what is under the patch. Does this forum also involve customer care? We bought the TV almost 3 years back. Not sure if the international warranty that I got still exists. Need to check. Appreciate help. Cheers!

I am having the same issue. My LCD's model is KLV-32BX300. I bought that TV 4 years back. The TV was working fine before that issue. The amazing thing is that the patch was initially a small spot and it size got increased within 2 days even the TV was powered off. Please help...

Webdynpro on loading shows a black and white type of screen

Hi Gurus.
Don't know if anyone had this problem before.
Some of your webdynpros on running show a black & white type of screen with no background colors. Buttons are visible, but clicking on them nothing will happen. I don't know if you all understood what I am saying. Unfortunately I cannot attach screen shot
Basically the background becomes all white. No groups in blue color. No table lines.
It happens only intermittently, user refreshes, and it gets okay.
Anyone faced this problem before? If so, any solutions found for it?
Thanks in adv.

Hi Aishi,
the only other time I've seen something like this, has been when I've been messing around with the portal theme (in that particular case I was trying to apply the portal theme to a BSP which had been called dynamically in the app and was not therefore correctly picking up the theme .)
That said - the problem was never intermittent for me then - either it worked or it didn't!
I'd be trying to find a way in which you could replicate the issue, (potentially clear all the cookies local files etc from a user's machine) and then putting a program like HTTPWatch on to check if there were issues picking up any particular files in the user's request.
Cheers,
Chris

White patch after removing row from JTable

I am working with JTable and removing item from table on clicking on button but after removing row there is white Patch on that row. I don�t want to show this white patch.
I did repaint table but that is also not working.
Any thoughts !!!!!!!

javax.swing.SwingUtilities.invokeLater(new Runnable(){
            public void run(){
              museTable.setBackground(Color.black);//your color here
          });

I'm not able to see video from utube or from other source. I get a white or black screen. I have down loaded flash player and no change.

I have downloaded flash player. I still get a white or black screen. What should I do now?

Try downloading Chrome, the browser from Google, and see if you can view YouTube, etc., videos. If so, there's likely a problem with your Flash plugin. Which browser are you using now? If Safari, go under the Help menu to "Installed Plug-ins" and make sure that you see "Shockwave Flash".
Also, if you've just installed Flash, make sure that you restart Safari.

Black or White patches on Photoshop images

I use Photoshop CC on a new iMac. Recently my images have been randomly filling with black or white at varying zoom levels. Or they have rectangular black or white patches on one corner/side. If I zoom in or out these fills/patches will disappear at some levels and reappear at others. Anyone have any idea why this is happening and what I can do to rectify the problem? Shutting down PS and/or re-booting the computer usually deals with the current issue, but then the problem reappears on another image at a later stage. It's happening frequently enough to be very annoying!

Google updated the plugins recently to correct this problem:
https://support.google.com/nikcollection/answer/4400822?hl=en&ref_topic=3001406
Version 1.109 (December 11/2013) is the latest:
Fixed black or white tile artifacts that might have occurred after returning to Photoshop from plug-ins
You can find out the version you have installed by launching Photoshop:
On Mac: Select Photoshop>About Plug-in>Analog Efex Pro… (or any other NIK Plug-in)
On Windows: Select Help>About Plug-in>Analog Efex Pro… (or any other NIK Plug-in)
