Full auto mode=black screen. M mode=bad pic; only works on highest ISO setting

I usually use the full auto mode on my camera and it worked great. A few days ago, I used the M mode to take some shots of my son's birthday and everything worked great. The next day, I went to use the full auto setting to take some pics outside and the picture was black. The flash won't raise in full auto mode. When I use M mode, the only way I get a picture is if I use the highest ISO (6400) and even then, the picture isn't great. I tried resetting to default thinking that would work, with no luck. Please help! I spent a lot of money on this camera and don't understand why it all of a sudden stopped working.

Exactly. In Manual mode your shots may be solid black or white if your exposure combination is 3 or more stops off one way or the other. Try starting with AV mode (aperture priority mode) or TV (shutter priority mode) before moving on to Manual mode. In those modes you only have to set one of the variables (aperture or shutter speed) and the camera manipulates the remaining variables to give you a correct exposure. Google videos on the exposure triangle and on Av and Tv mode. There are dozens and dozens of good free tutorials by both pros and amateurs to help. Also I recommend buying Bryan Petersen's excellent and easily understood "Understanding Exposure".
And if we are talking about a camera with a viewfinder you really should be using that instead of the LCD "live view" anyway while handholding. Bracing it against your face with your elbows braced against your body is so much steadier than holding it out at arms length like a phone camera. PLUS the camera focuses much much slower in live view (using the LCD) than it does using the eyepiece because in live view the mirror is flipped up for video and so it is having to focus in a different way than normal.

How do I get my iPhone 5c out of black screen recovery mode?

I have been trying for countless hours and days to get my iPhone 5c out of recovery mode (black screen no apple logo or anything else) the only reason I know it turns on is because the backlight LCD changes color. When I press down on it it leaves a little finger pressure thing. I have tried all of the ways to get it out of DFU mode, Out of Recovery Mode, I have tried restoring it, in which case i get the error 4005,40013 etc. So now I have come here for my last hoorah on trying to get this pile out of recovery mode and the IOS installed and working.
I don't know if this matters or not but, I have recently purchased a screen from ebay, it was an original iPhone screen etc. I have replaced it and as i said the screen works fine. that shouldn't have any problem with the actual software malfunctioning to update, but here is the log! Enjoy!
All help is greatly appreciated and I will do my best to give credit where it is deserved in the future! God Bless!

I ran into the problem you have after trying to update to 7.1.2 the phone updated, but got stuck in recovery mode, and none of the reset methods worked. I did some searching and came up with a simple method, and it got me out of the loop.
Once i used this app, My phone booted and The update was in place.

HT3529 Message Notifications show up in lock mode when screen is on, but not showing on black screen (sleep mode).

My texts show up on my lock screen, but not on my black screen (sleep mode). They used to, but not anymore. I have "show messages in lock screen" turned on, but I don't see any options for sleep mode. I have banners turned on. All settings seem to be correct, but in order to see my messages I need to turn on my screen, which is frustrating b/c then I don't see messages when they are first sent. Any advice? Thanks.

Thanks for the response, but I've tried that and it doesn't work. I have friends and family who have their settings exactly the same as mine (including banner) and they get notifications in their sleep screen. It's all very odd.

Macbook spontaneously goes into sleep mode and screen off mode

Hi. My Macbook spontaneously goes into sleep mode and screen off mode with varying time between each instance. It usually goes for a few minutes or even hours without doing it and then will go through periods of fluctuation between the modes. I believe this to have started with a minor orange juice accident rather than it being anything software related.
Any ideas as to how I might rectify the problem? Thanks very much in advance,
Danny

When you say it goes into sleep mode ...do you mean you actually see the white pulsing light?
It may be that there is an application running (perhaps in the background) that is keeping your book awake. Printer software sometimes does this for example ...try logging out and seeing if it sleeps like that. If it does, then it very well may be a background process running.
You may find some items in System Preferences/Accounts/Login Items that may be the culprit.

Screen actually seems a very dark navy blue almost black. sometimes can see cursor in white
Only happens sometimes

If you can somehow document any processes you've put the MacBook
through, which can cause it to repeat the symptoms you've seen, be
sure to write down the sequence of events if your action and resulting
issues can be make re-occur. Then you'd have a fair chance at some
one looking deeper to find the real cause of this problem. {If you have
a digital camera handy, you can take a picture of the screen if it should
display some curious content other than a black screen, such as that
seen in a kernel panic or other message. Otherwise, a working Mac
can take its own screenshot.}
The computer should be returned to the Apple Store genius bar for
further evaluation & more in-depth diagnostic tests of long duration.
Sometimes a test may not run any of the additional software, together
or separately, that you may be accustomed to using. Perhaps the basic
OS X and a few applications work just fine.
If the issue is due to a conflict in software and not a hardware failure,
the cause may be harder to discover. If you have a complete backup
of the system and your files on an external drive, that may help if you
need to reinstall it. However if there is a problem in that software set
a new installation without conflicting software may be required in order
to troubleshoot the machine.
How old is the computer, how much RAM installed, how large a hard
disk drive and what is the remaining unused capacity of that drive?
(The HDD capacity will show 'other' so that may be unsubstantiated.)
Are there any indications in Activity Monitor, or in the system log files
from Console, to show crash logs or other effects from the Time/Date
of these slow wakeup and black-screen intervals? There may be.
Some of the system report may be helpful to those who know how to
read the resulting mass of files. Perhaps one of the more advanced
users who occasionally reply here will see your thread and offer a
method of accessing the OS X via Terminal or single user mode,
for troubleshooting purposes. Mine is an older OS X with less fuss.
Good luck & happy computing!

Double tap Home button and delete Camera app from multitask-list.
Do a
Reset: Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Note: You will not lose any data
If problem persist, make an appointment with genius bar for evaluation.

The principle is the same...

Power save mode- black screen

k7t turbo2 board, tdk 40/12/48 burner, toshiba dvd rom 16x, compaq 30gig hd, 1 pci in use for 56k modem board, athlon xp 1700 tbred, antec 280 watt psu, and a diamond *savage 4 (agpx4) with sdram connected to AGP slot.
Upon installation into a new antec case, with everything hooked, I turned on the power and received a black screen through boot up. The only message was: Power Save Mode and it came from my Sony 19'' trinitron E200. It recognized that there was power, but I got a black screen which leaves me in the dark as to what to do - I can't make fixes from a blank screen.
I did connect the 12v to the JPW1 slot, is that the problem?

I think my words came across wrong, sorry.
The power supply is 300w Antec
I read the post about AMD's first so I wrote my post a little different.
The 5v and the 3.3v combined max is 220 (that is more than the 180 standard) add the 12v to the mix and it's 280. With the 3.3v I'm pushing 20a.
This seems like enough (according to the tech. I bought it from even though I'm sure he was bias).

Froze on black screen and power button does not work

my sons ipod touch is stuck on a black screen when plugged into the computer got a spinning wheel and will not connect now spinning wheel will not go away the power button does not work so can not reset it manually
any suggestions would be appreciated

- iOS: Not responding or does not turn on
Neglect the reset and when it says place the iPod in recovery mode use one of thes programs
- 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 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.

Mid 2010 Mac Pro, Black Screen on start up. Video works after I turn machine off, let it cool

My Mac Pro is acting up.
If I do a reset after its beenruning for a period of time I get a black screen at start up. I have tried multiple different monitor cables and nothing seems to work. It does seem to resart and I can here the start up chime but no display. If I unplug the machine and let cool for 1/2 ~ 1 hour it then turns back on with no problem.
Processor 3.33 GHz 6-Core Intel Xeon
Memory 24 GB 1333 MHz DDR3 ECC
Graphics ATI Radeon HD 5870 1024 MB
Software Mac OS X Lion 10.7.4 (11E53)
Display is the 27 inch cinema
Any ideas? Bad graphics card?

AC if you used it this once would pay for itself. Same for a good solid UPS - a good one can stop that 1/100,000 surge that takes out a modem (if you filter of course).
I've known people that never knew you could filter coax cable or dsl and we get enough severe storms it has been, not if it happens, but when.
Unlike the X1900 which had a air chamber and would cause clogging you really should not need to and be pulling it out to clean dust all that much if at all.
People have gone through 2 or 3 ATI 5770s and some 5870s due to what are probably design or bad batches especially the first months run.

Hello there, vsanfilippo2.
If you're iOS device isn't recognized at all on your computer, then the following Knowledge Base articles provide some great troubleshooting steps to follow, depending on the Operating System running on your computer:
iOS: Device not recognized in iTunes for OS X - Apple Support
or
iPhone, iPad, or iPod touch not recognized in iTunes for Windows - Apple Support
Thanks for reaching out to Apple Support Communities.

My camera is not working, just a black screen, won't take pics please help

WWhy won't my camera take pics..just a black screen ?

CClose the camera app and reset the iPad.
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Black screen after system restore, notebook stops working.

Now what I did is: The restore took too long. It said 3 hours and it went up continuously.
Yup, probably something corrupted in the backups of OSX.
I reinstalled OS X and I am now restoring my personal data from backup within the setup assistant.
However I don't know if iChat works again.
If it was a problem with OSX or the iChat app, you've got a new version of each, so probably.
Keep us posted.

Text deletion in BADI DELIVERY_PUSH only works in DEBUGGING MODE

Hi, I am facing a peculiar problem. I want to delete the Delivery text created in VL01N. I have used BADI DELIVERY_PUBLISH to perform the task . This BADI is working only in DEBUGGING else text not deleted. Please help me .
Regards,

You could do something like the attached modification.Note how I modified the connector pane for the subVI to use the conventional 4-2-2-4 pattern and notice where I connected the terminals.
NOTE: I am assuming the VI is supposed to run just once, and that you're not using the Run Continuously button in the toolbar. You're not, right?
