Black patch on my screen

Hey guys, i just noticed there's a black patch on my screen. Bottom right has bigger patch and its obvious on the grey loading screen or any bright backgrounds. Is it something i should worry about be it dirt or burnt? Im using Macbook White Unibody late 2009 model by the way. Thanks.

Hi..
I too just noticed a spot on the right hand corner of my screen. The spot is as tiny has the tip of a .5mm pen..:P
But yeah, I had a word with the apple store who told it may be a case of pixel damage. I'm taking my mac in next week, you might wanna talk to your local apple store about this..Better safe than sorry i guess..Cheers ..:)

Nokia Lumia 720 screen has black patches within on...

Hi,
There is a major concern in the case of my Nokia purchase with respect to the below issues
1) Quality of product
I bought my Nokia Lumia 720 from an online retailer and in a week, I discovered there is a black area on the screen which became very obvious in the white backgorund (I couldn't notice it earlier because Windows mainscreen uses colored tiles on black background). Please see the picture attached.
Just in a week ? Or maybe it's a manufacturing defect
2) Quality of Customer service level and support
I reported this immediately to the Nokia Customer care through an email and they asked me to take to the customer care centre. I wrote them stating my concerns and if I can get a replacement. They didn't discuss it and just asked me to visit the Nokia Care.
Having submitted it at a service centre in Bangalore, India, they were clueless about the issue as it was their first experience with Nokia Lumia 720.
They concluded that the battery has bulged and they need to further investigate. And they tried to put blame on me assuming I might have put the device in water, over charged it or if I fiddled with the battery
I've not done any of the above and I told them, for users the battery is not removable
They argued that it is possible to remove because they could remove. I told them, fine but I haven't
They informed me they'll update me.
Only after I enquired two days later (they haven't bothered to contact me), they have sent the device to the headquarters in Delhi and will take 10 days minimum. And I'll have to pay for repair
Pay for the repair ?
What I can't take it is they told there would be an amount charged for the repair.
3) Fairness of treatment / Customer satisfaction
It's been one week since I purchased the mobile, I'd sent out my first email bringing up this issue. I've paid full money to purchase this. I've already informed that I have not taken my device near water or over charged it or dropped it. It has been a very normal usage.
I've co-operated in every possible way. And if the device is found damaged in a week, shouldn't it be replaced ?
I had raised the same concerns via email but I've stopped getting any response from email specialists at nokia care after an initial reply.
I'm worried because there is a similar description of the issue in the following video and the person got an immediate replacement
http://www.youtube.com/watch?v=pYsK0c-wXvI
Since I bought it from an online retailer, I had no option but to visit the Nokia Care.
I'm feeling like a fool as I purchased a Nokia in 2013 much against the popular opinion of getting a Samsung or an Apple.
Will I get a replacement ?

Black Patch on Nokia Lumia 720.jpg ‏876 KB

Hi

Also within a week all the data had been used up and no idea why. Fortunately virgin replenished the data limits so this must have happened before.
So far I am thingking it is a heap of junk.
Any Ideas?

Imac time machine obscured by black patch

When I use time machine everything appears to work correctly but most of the screen is obscured by a black patch. I attach a photo (taken with ipad) of the screen. I have tried shutting down and restarting but to no avail. I have no other problems with my imac.

If you have an external display connected, try disconnecting the external display and then use TM. I have a similar issue when using an HP external display, I was never able to locate a fix other than disconnecting the HP display.

Touchsmart 7320 black patches at bottom of screen

When PC has been on for a few minutes a dark patch appears at the bottom left towards the middle of the screen. A while later this extends across to the left bottom corner. It clears only if I reboot or change user and go back in. It has been suggested that the LEDs are failing.

Screen Sharing display of Finder app lags & black patches

I'm trying to share the screen of a headless Mac Mini with a Retina MBP over ethernet (via thunderbolt display and time capsule) using the built in screen sharing app, and my fourth generation iPad over wifi using a VNC app. My problems are as follows:
- intermittent black patches over the screen which I have drag a window over, or move a mouse over, to make disappear. This only happens on the Retina MBP, and doesn't happen on the iPad. This is considered solved in another thread, but the solution was to update Apple Remote Desktop which I do not have installed.
- On both Retina MBP and iPad, the outputted display does not update when I make a change in the Finder application. E.g. say I create a new folder. I will not see the folder I have created until I drag the window elsewhere.
This problem is the same regardless of the display quality (full or adaptive), or the resolution.
I appreciate any help.

IPhoto editing results in black patches on photos - new problem

Hello everyone - I am experiencing a brand new problem with iPhoto editing. Have used the editing feature for four years without incident. Since upgrading operating software a few weeks ago, I now experience sudden blackout patches on photos as soon as I click on the "Adjust" setting in the "Edit" mode.
Here are a few details on my set-up and problem:
iPhoto version: iPhoto'09 - Version 8.1.2
Operating System: OSX Version 10.9.1
Details - Black rectangular patches appear in either sections of photos, or completely obscure the photo whenever I click on "Adjust" in the "Edit" mode. Only way out of this situation is to hit "Escape" key
Did it every work properly? Yes, for four years I never had any problems. Liked the ease of the editing features in iPhoto. Very recently upgraded operating system to version noted above. Problem occurring since that time.
Error message? No
What steps taken to date? None yet - Seeking assistance through this forum. Thanks in advance.

As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?
Post back with the result.

Blank screen with a black patch (see pic pls)

My Toshiba Satellite L755 is blank, when I turn it on, it goes immediately to that screen and it doesn't change. I can tell the system is working, but no screen. Any ideas of what is going on will be appreciated. Thanks.

T61 LCD display flickering with big patches of black and going to dark (very low light) afterwards

I have a T61 which has Intel graphic card. It is seven years old and at times has a noisy fan.
Very recently it started to have problem with its LCD, it starts with slight flickering of light intensity from corners of screen, here and there, eventually covering the whole screen, goes away and comes back, happens for few seconds, the pattern repeats for few times, then big (screen-wide) patches of back starts to cover the lower 1/4th, one-half, 3/4th of screen, flickering between the screen content and black screen, till they cover the whole screen after 30-60 seconds. At that moment, the screen is very dark but with a close look, it is still possible (but very hard) to read it. Connecting it to external monitor (through its VGA), it is working very well. Showing same screen on both LCD and external monitor at the same time, the picture on external is solid, but picture on LCD can have this issue. At the moment of writing this message, the problem seems to not happening!! but it was happening during the past whole week including few minutes ago. I searched online and here in the forum and read few posts, and found about these issues:
- some T61's have Nvidia GPU and thermal effects over the time and stress on the package or solder balls can make loose connections (this is probably not my case since the interface to graphic card is by Intel)
- problem with LCD itself (it is working fine just right now)
- problem with graphic card (it is working very well over the VGA to external monitor)
- problem with the ribbon from mother-board to LCD (tilted the screen in different angles when the black patches and flickering are happening and didn't change the chaos much in any direction of making it better or worse)
- problem with bulb inside the screen (maybe the cause, but somehow decided for the last few minutes to working fine)
- problem with inverter (don't know yet what this part it)
- problem with some sort of mechanical part(s) being loose, gently tapped on sides and back of the screen while the phenomena was happening and again didn't have much effect on it in any direction.
I appreciate your time and good gesture of help, many of you would know more scientific/engineering ways of approaching the problem and how to root cause it. My sincere thanks beforehand.

> the screen is very dark but with a close look, it is still possible (but very hard) to read it.
That sounds like a defective CCFL backlight or inverter.
>- problem with bulb inside the screen (maybe the cause, but somehow decided for the last few minutes to working fine)
A CCFL is essentially a high intensity fluorescent bulb. One failure mode is flickering.
>- problem with inverter (don't know yet what this part it)
The inverter is a power supply that converts the low voltage DC used in the rest of the ThinkPad to high voltage to drive the CCFL. I would expect that to fail catastrophically rather than cause flickering.
What to do?
CCFLs backlights are relatively inexpensive ($10 to $15 on eBay) but they can be difficult to replace because they're delicate. You may prefer to replace the entire LCD panel assembly or even the entire top cover assembly (which also includes the inverter card.)
The Hardware Maintenance Manual for the T61 provides detailed instructions for doing this sort of stuff if you'd like to see what's involved and decide what you feel comfortable doing.

SCAREY Black squares-"patches" in camera roll

how to remove black patches in the camera roll on the iphone?....

First remove all the photos from your phone and do a hard reset (home + power buttons until the apple logo appears)... Then check to make sure you have no black boxes....
Then try installing photos in bunches rather than all at once. There are a few ways to do this using the "selected photos" option in the photo tab in iTunes. I like to do it in small groups - say 10 photos at a time - until the problem shows up again ...once I find black boxes, I would remove that group and then sync those photos one at a time until I find the problematic one... and just keep on doing this until you isolate the problems - delete the problem photos (or put them in an album that you won't sync) as you locate them.
Other people recommend syncing half your photos - if black boxes appear in that group... delete the photos from your phone and then divide that group in half (sync 1/4 of your photos), etc. etc until you find the problems.
One thing that helped me find some of my corrupt photos (18 out of more than 15,600!) was that sometimes (but not always) iTunes would give me an alert box saying that a certain photo (identified by the file name) and XX others couldn't be sync'd because it wasn't in the correct format. So this helped me locate about half of the bad ones as I was going through the process. Unfortunately, iTunes never gave me more than one file name at a time - it would be nice if Apple revised that error message to give you a list of everything that was "in the wrong format."
So as not to lose the photos, my plan was to export them from iPhoto, delete the ones in iphoto, open the exported photos in another application and resave them before importing them again into iphoto. But as it turned out, every one of my corrupt photos turned out to have a duplicate in iPhoto... I can't say if this was indicative of the issue, but if you have a lot of photos you might want to try creating an album of just your duplicate photos and see if this is indeed a bad group.
It's a time consuming process, but worth it. If those corrupt files are causing issues in the phone, they might very well be causing other issues in your system.
By the way, once I got rid of the corrupt photos, syncing was infinitely faster....so I guess they were really hanging up the process

Images with black blotches showing up.

I have a wierd problem with picture quality that just started showing up.
The black detail in certain areas of the picture is becoming overly black. Blotchy black areas especially on the screen and in prints. Black detail becoming overly compressed. The gradation between light and dark on my 23 HD and 17 Cinema display shows as layers of black, not a continual gradation to black. To explain it another way, the gradation of black colors (when going from light to dark to black) appears on the screen almost like Newton's Rings. I'm starting to get blotches of black in the darker areas of my monitor images and now on the prints. All the pictures are RAW (shot in Adobe 1998) from a Nikon D70s. None of the images have been altered in any way. No color correction, exposure increase or decrease, nothing. Straight RAW files imported directly into Aperture from the camera. I have printed all these pictures before and they looked fine. Now they have these black blotches in them. Not all pictures have the problem but the ones that have the darker black gradations (primarily to deep black).
I have a custom .ICC profile I use for printing and the monitor was calibrated too, using ColorVision tools. Spider2Pro and PrintFix Pro. But even is I use the standard profiles for the monitor and the printer, it's still the same.
The wired thing is, if I open the image with an external editor, Photoshop CS2, I do NOT get the same problems on the screen as I do with Aperture. (I have not printed yet from Photoshop CS 2 since this started, only viewed.)
This is just a recent problem, and as I said, I have been printing the same pictures before and viewed the same pictures before with no problems. I noticed this starting to happen after the last 2 updates for Aperture, and it has progressively gotten worse.
Any picture that has a continual gradation from a light black to dark black to full black has this problem. (On a 9 zone gray scale - say zone 5 thru 9)
Equipment Notes: Aperture 1.1.2, Mac OS 10.4.7, Apple 23 HD display, Apple 17 Cinema Display, Dual 2 GHZ PowerPC G5, 3.5 GB RAM, 2 SATA internal Hard Drives, (the one with Aperture has 30 GB's left on it and the other that I use as Vault Back-Up has 164 GB's available. Video Card - ATI Radeon 9600 Pro, AGP bus, 64 MB RAM
Epson Printer - R2400, using K3 inks on Premium PhotoLuster paper.
Does anyone else have this problem? Do you know how I send this problem to the Aperture Team?
P.S.
I too have notice a tremendous slow down in Aperture as of late as other people have stated.
I too sometimes don't get a image in the viewer. I sometimes only get the Right half of an image in the view. I can get other pictures to the left and to the right of the image in question but Aperture sometimes just picks a picture to only give me half. I must shut down and re-open Aperture to get the complete picture on the screen again. I can't figure that one out.
Thanks,
Jim

Well, besides my 2 previous posts, I would like to add something. I started printing and everything was going well once I turned On Screen Proofing off.
Oh, I guess I must first point out that I have calibrated my Monitor and Printer, using ColorVision's Spyder2Pro for the monitor and their PrintFIX Pro for the printer. It looks pretty good. But here is the problem.
As I started to say, after I turned off On Screen Proofing everything looked good, on my screen and my prints. I started to print using my Colorvision settings and my custom ColorVison printer profile. It worked for a while on some prints but I ran a print with a long gradation of black to deep black and that replicated my original problem. Blotchiness and striations of black. I found that if I printed with Epsons' ICC profile it was fine. So the ColorVision profile didn't work on some prints with deep gradations of blacks.
So I called their tech support. They asked if I did their 225patch target or the more extensive 700 patch target (I'm not sure of the correct number of patches). I had done the shorter 225.
They told me this is a common problem if you only do the 225 Patch Target and that I would have to do the 700 Patch Target to not get black patches/striations in my prints. As a note: the striations looked exactly like the On Screen Proofing problem when it was turned on.
So as it turns out, I had 2 problems at the same time.
I haven't done the 700 patch test yet. I'll let you know when I get it done, how it works out and if the On Screen Proofing matches the print as suggested by firstlaunch.
thanks for all your help and suggestions!

How do I make the Black in Pages True Black? I make Newspaper ads and they are starting to look anemic.

How do I make the Black in Pages True Black? I make Newspaper ads and they are starting to look anemic.

Sorry Eric but that is the wrong specification and will produce a muddy brownish grey with possible registration problems particularly in small type as well as being wasteful on ink.

Open the Color Picker > click on the color slider tab > click on the color mode patch > choose Black & White > Brightness: 0% (black patch) > drag down to recognisable swatch below
To label it > click on the color sets tab (3rd tab) > click on the gear > New > Rename the set "DrD's > drag down the swatch from the bar above > Label that 100k > click on any stray swatches and rempve by clicking on the - button below
These swatches are System wide and available to any application that accesses the Color Picker. Unfortunately Apple has not seen fit to make them easily transferrable or saveable and importable.
Make the 100k swatch part of your Styles in the Styles Drawer, particularly the text to ensure it is used, you can't spot it on screen and there is no feedback anywhere that it is selected.

Vertical black stripes at bottom of screen

After updating to OSX 10.6.8 I have noticed that my MBP 2.5 GHz Intel Core 2 Duo has vertical black stripes at the bottom of the screen when I start it up. I cna still use it, but the stripes are very distracting. I thought it was a hardware issue (like my screen is failing). But the solution suggests that it is a software problem.
The solution is to retart the computer after its initial bootup. When it restarts the black stripes are completely absent and the computer runs for long periods of time (like for days) with no problem at all, even when it goes to sleep and then wakes back up.
Anyone else have this issue?

Photoshop can't print legal-size image to legal-size paper

I go through a lot of sketch stages to get to a final picture, and I sometimes print on legal paper. My Brother printer does fine at that with Apple Pages, MSWord, Acrobat, and Illustrator, but with Photoshop there's a problem. I set up a legal-size image in PS, go through all the settings I can find for printing to a non-letter-format sheet, hit print, and what I get is a letter-size patch of image on a legal-size sheet. Clearly, either I am missing something or PS is missing something. Any ideas or suggestions?

The problem persists. This has gone on for months, but now I've updated to OSX 10.9.1 and the latest Brother printer drivers. I still get legal sheets bearing letter-sized information. So far, the only answer anyone has had is to check every possible place where the paper size is defined. Right. How many of those are there? 2? 3? 4? See attached screen grab: I don't know what it's doing there, but the black patch at the bottom of the image corresponds to the cutoff area on the print. It shows up when I check the box "Print selected area". Otherwise, all the sizes and labels i can find are legal-paper sizes and labels. So how do I get rid of the black box? Note that, below, the "Print selected area" box is unchecked
