Blqack screen, no chime and it's not a video issue
Hi, I got a big problem and I will like to know what your thinking about.
When I try to open my Intel-Based IMac, there's no video. The screen is black but the light came on and the drive and the fan make a sound. The keyboard and the mouse doesnt work and the computer doesnt make a chime.
I tried to find some info on the website of apple
http://docs.info.apple.com/article.html?artnum=300537
but it's not the same problem. The fan and the drive is working but I dont have the chime. Then it's not only a video issue, it's not only the display who is not working because the mouse and the keyboard doesn't work and the chime didn't came on.
It's the second time it do that. I didn't install a new software for the last week. The fist time, the technical support told me it was probably a software issue. After a while, I was able to turn on my computer and I made every update. After that, I made a reboot and everything worked. I taught it was ok and I turned off my computer. After the night, the same problem came on. I tried again to turn on and nothing worked. Black screen, no keyboard, no mouse, light turn on, the drive and cd make a sound and no chime. And this time, I was not able to turn on after many reboot with the power button.
I think it's a problem with the computer himself and not a software issue but I dont want to send my computer to a apple store before to confirm it. I need my computer as fast as I can and I don't have a retail neer of my home.
Your symptoms, though not exactly the same, seem to indicate a problem with your RAM. The startup chime is a signal that your Mac has passed the Power On Self Test and suitable RAM was found. No startup chime is usually a sign of bad or poorly seated RAM.

I would start by removing the RAM modules and test them one at a time in each of the RAM slots to rule out bad RAM or a bad slot. Then seat both modules securely.

When I am on a phone call and I double click the button to go to my home screen, then open another application (usually my calendar program, Calengoo), my screen goes blank and I am not able to return to either the app, the phone, or the home screen. If I am speaking to a person, if they hang up then I am back to the phone application. If I'm leaving a message, I am unable to return to the phone screen to end the call, and have to wait until the other phone hangs up. I'm also unable to switch back and forth to look at my calendar if I'm calling someone about scheduling. This has only started happening since the most recent iOs update. I run into situations similar to this about once per day during the work week, as I use my phone is this manner quite often. While not life altering it is quite frustrating. Can anyone here help me figure out a way to avoid this? If it helps, I have noticed a general downgrade in overall performance starting two system updates ago (apps opening more slowly, closing unexpectedly more often, etc.). I have an iPhone 3GS with the latest OS update.
Thank you for any help or suggestions,

You can check the notification settings for message.
Settings>Notification Center>Messages>Alert Style
It should be on Banners or Alerts.
Settings>Messages> Turn on Imessage and send as SMS and below that "Blocked" to check if you have any numbers block might be blocking the message.
You can also do a hard reset by holding power and home till it restarts and release after seeing the apple logo.

Dear Adobe.
Yesterday I installed the latest version of Flash Player that auto appeared on my screen. Ever since I can not play video, and my system has become painfully slow. I have Mac OS Lion 10.7.5 and software is up to date. Before this everything was running beautifully. Can you please provide a link so I can uninstall the latest version only. Thank you. Stephen Kress. Melbourne. AustraliaWhen you run the uninstaller, it will uninstall all Flash Player versions.
If you want to revert to an older version after that, get it from http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html -

Thank you for visiting Apple Support Communities.
This sounds like you may have enabled the Zoom feature. Here are the steps on how to disable this feature.

My Ipod nano touch is not charging, not showing in my PC or laptop. Last I saw an apple icon and low battery signal. There after the screen is black and no power not taking AC or PC charge. What Can I do?
If the Reset didn't work, you'll need to do a Restore.
From iTunes, select the iPad and then select the Summary tab. Follow directions for Restore. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finished, you will be asked if you wish the contents of iTunes to be copied to the iPad. -
How come when I try to open an app on my phone does the screen just blink and the app not open?
How come when I try to open an app on my phone does the screen just blink and the app not open?
Some apps crash. If they do, try this, in order.
1. Double click your home button and put your finger on any app and hold for a second. Then delete that app. You're not deleting the app from your phone, so don't worry. Then try opening the app again.
2. If that doesn't work, hold your sleep+home buttons for 10 seconds and don't let go. Ignore the power off message. Then try again.
3. If that doesn't work, delete the app and re-download it. (This will work most of the time)
4. If that doesn't work, download the app on iTunes on your computer and sync it from there.
5. If that doesn't work, wait for an update by the developers. -
n the middle of looking through some pictures, my iphone 4 screen turned white and is now not turning off or on. What's the best thing to do?
Try doing a hard reset - by holding the 'Power' button on the top and the 'Home' button simultaneously!

I have Iphone 5 and updated to IOS 8... I can not receive a call, the Screen become black and I can not answer the phone call
Hey there jjroca,
It sounds like you are unable to make or recieve phone calls because the screen goes black. I would start by quitting all the running apps on the device:
iOS: Force an app to close
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
When you have done that restart the device and test the issue again:
iOS: Turning off and on (restarting) and resetting
If that does not resolve the issue, I would use the troubleshooting in the following article, named:
iPhone: Troubleshooting issues making or receiving calls
Thank you for using Apple Support Communities.
Take care,

! just got a new docking system so i plugged it in to my computer because it wasnt the wall charge type, so I put in my ipod, then straight away my screen went white and now its not doing anything! i press the home and lock button nothing happens... then i plug it in my computer it doesnt come up in itunes or even the copmuter. please help i can not live with out my ipod!
Your post is abit confusing, especially on getting those weird messages and emails,( assumed in your Windows machine.)
Most likely you have Restored the iPod using the new Macbook pro, using the same name as that in your Windows machine, hence the duplicate name warning, as it is trying to sync Automatically.
If you are syncing your iPod to both the Mac and Windows, you must set it to Manually Manage Music, in the first machine that you setup iTunes with the iPod. Read thsi Apple Support Article
In iTunes, Preference, tick on Prevent devices syncing automatically
Hopefully your music are still in both your iTunes library,
Connect the iPod to the Mac
Restore it (just to fix any filesystem corruption by the Windows end)
Set it to Manually Manage Music
Sync your selected songs in your library.
Whern sync complete, Eject it
Connect it to your Windows PC.
Select the song in the library
Sync it.
It should work if your ipod Hardisk is not giving any problem.
Good luck! -

My iphone 5 screen goes blank and i am not able to do anything
My iphone 5 screen goes blank and i am not able to do anything. It happens in rainy weather and it comes back to normal after 3-4 hrs.
If you get your phone wet you risk permanent damage. Do not use your phone in the rain.

Having horrible service with 4GLTE I have had 3G for several weeks (I am not the only person I know having this problem), I have reset my network settings and it did not resolve the issue. I am also unable to send SMS and text messages without them either failing or not sending at all. Is there an outage in the Cleveland, Ohio area (zip codes 44129, 44134, 44137) or anything else I can do to resolve this issue?
Not that I'm a Verizon employee, but I have experience in the field. An LTE tower will only extend up to, on a perfect day, with no elevation, 6-7 miles. On a typical day, you will be lucky at four (4) miles. The three ZIP codes you've given are all within about a 12 mile radius. That would mean that 2-3 towers are currently down at the same time, and Verizon would know about it within the hour. Being it's Cleveland, I'm sure they would receive numerous calls regarding an outage of that size.
My point is that if you're having issues in all three ZIP codes, chances are it's a phone issue. If you're handset is simply not receiving LTE, but still receiving 3G, that would signify a SIM card issue. You need to get your SIM card replaced.
