MacBook not sending signal to external display - was working fine before.
hi guys, i have a unibody macbook and i've been hooking it up to my tv for almost 2 years now using the mini display port to hdmi adapter and hdmi to my television.
tonight the macbook randomly stopped sending signals to the tv. i tried two tvs with two different display adapters as well as a DVI monitor.
the displays are detected in osx but there is just no signal sending to it. anyone have any ideas? did my mini display port just die? i've tried several cables/adapters.
Hey,
I just experienced a similar problem as the original poster, except that I'm using a minidisplayport - DVI adapter and not HDMI. Been working fine on my external screen for 2 months now and suddenly the external says no signal?
Macbook still flashes a blue screen when plugging in the adapter but does not detect the external. Haven't ruled out that the adapter is busted yet, but worked fine earlier.
I tried resetting the PRAM without any change.
Any kind of software / hardware problems on the macbook?
Any thoughts?

I have a 3GS and since I did the IOS6 update my phone won't send pictures via text message. Anyone know how to fix this?
Do you have the Onavo app installed? If so, try removing it.
1. Go to your Settings app -> General -> Profiles
2. Locate the profile called "Onavo"
3. Tap Remove
4. Go back to your home screen and delete the Onavo Extend icon -
My Macbook (2009 White) Has had water spilled onto it, it all works apart from the screen. When connected to an external display it works fine, just not on the Macbook itself. Does anyone know how to fix this?
Take it to Apple and ask them to fix the physical damage the water caused.

i had recently followed orders to restore my iPhone 3gs (iOS 6.1) from a question on apple support. However it was working fine before that, it's just that my phone didn't have signal. So it said to restore my iPhone and now it says that the Activation server is temporarily unavailable and when i plugged it into my mac, it said that i ddn't have a sim card installed. What can I do to fix this besides bring it to the store? it also bugs me because this answer was supposed to work but it just messed my phone up even more. This has already happened once and i had to take it to the store. What should I do to fix this? Thank you so much for all answers. i really appreciate.
no so i dont know what happened

I am traveling and cannot connect my bluetooth keyboard to my MacBook Pro where I am. It was working fine when I left home. What can I do to fix the problem?
If you can get them paired again try making them "favorites" from the Bluetooth system preferences.
Try smc and pram reset too. May gave to do this before you can get them paired. -
drag and drop to photo shop no longer works after installing Apple "Photos"; It was working fine before the latest Apple update (10.10.3) . what can be done?
Nothing. It's nothing to do with PSE; this is a limitation of Photos, as is the loss of being able to use an external editor without exporting copies of your images.

Hello darkhawk,
Thank you for the recommendation. I somewhat understand what a MS DOS disk is, but I'm not sure how to go about creating one. I've seen where you can use a program, like Rufus, to create a usb one - but I'm leery about using 3rd-party programs (especially ones I'm not familiar with). I've come across a couple of 'how-to' tuts, but they didn't clarify what files (if any) I would need to include on the disk (for my particular situation). Right now I don't have any blank cds, nor any extra flash/thumb drives - wish I did, but hadn't needed these for years. There has only been one other time where I needed to re-install Windows, but that was over 15 years ago - I did it through BIOS, reformatting my drives, and then reinstalled via the Windows XP disk. Windows 8 is an entirely different breed, which has left me feeling a bit stumped, at times. If there was a way I could perform it (successfully), similar to the first time I did it years ago, I'd give it a try - but at the same time, I'm a bit reluctant, because if it doesn't work, then I'm stuck without any internet access to get further help.
Ask and ye shall receive. This should be doable in Windows 7 and Windows 8 on another PC. I recommend using a USB Flash drive like in this tutorial, but I'm sure you could use something else.
If you want, you could also use Hiren's BootCD to make a bootable CD with many options and programs on it (I keep one, just for certain situations) that will allow you to do the same things.

It may have used the YouTube app that is no longer included in iOS. Try downloading the YouTube app in the App Store and see if it works.

my iphone 4 is stuck in restore after updating the lasted version. It was working fine before.How do I get it working again?
Hello, fschris.
Thank you for visiting Apple Support Communities.
When experiencing issues updating or restoring an iPhone, here are the best articles to go through. If you received a specific error number when restoring, see the section labeled Get more help in the second article below.

iTunes has stopped allowing me to import CDs. if I reboot it will import one, and only one. all was working fine before. the itunes diagnostics have all green lights
For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If you've already tried a complete uninstall and reinstall try opening iTunes in safe mode (hold down CTRL+SHIFT as you start iTunes) then going to Edit > Preferences > Store and turning off Show iTunes in the Cloud purchases. You may find iTunes will now start normally.

Why is not turning back on it was working fine before
hi my ipod touch doesn't want to turn on it was working fine this morning like the alarm went off and then a few minutes later it just turn off I guess because I pressed all of the bottons but still nothing just a black screen
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- 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 another cable
- 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.

I can't get netflix to work on Apple TV. It was working fine before.
Keeps saying Netflix not available....but it works fine on my laptop (Mac Air)
Are you getting all the icons on Apple TV or just computers and settings? If you are using wireless to connect the apple TV I have found Ethernet cable to the router better if that is an option for you?
