Hey there Daza2014,
It sounds like you are having some graphical issues with an TV connected to your mac mini. I found this article for you to help troubleshoot what you are seeing here:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
This section in particular:
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
All the best,
Sterling

I purchased my Macbook (17") through a certified apple tecnition in August 2012, it was refurbished and the motherboard was completely replaced. I do a lot of photo editing, but I have been unable to do so because of the red vibrating lines that interrupt my screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem. I brought the computer back to the technition I purchased it from and he said that it was a problem with my fan, so I have two new fans but the issue is still occuring. He says he doesnt know whats wrong. Does anyone have any information on this issue?
Here is an image of the issue
http://www.flickr.com/photos/67839707@N08/8884847081/I recommend having your Mac serviced by someone competent. A force sufficient to "blow apart" the fans was clearly excessive and may have damaged the display cable, as well as any number of other problems.
Dust is properly cleaned with a vacuum, preferably one designed for computer service, and they are not cheap.
Compressed air should never be used. It just blows dust everywhere, often into places where it can no longer be removed. -

Has anyone else seen this before, I needed to lock and unlock iPad to get back to the home screen.Aloha Ethan. Fortunately it's working as designed, but you'd never believe how many people wanted to argue with me smply because it worked differently. Can't please everybody I guess. Bob.

How can I connect my Ipad Air to my PC to see the Ipad screen on the PC?
I have connected them via the Ipad to a LIGHTNING DIGITAL AV ADAPTER-ZML connected to a APPLE HDMI TO HDMI CABLE (1.8 M)-ZML, and to the HDMI port on the PC. But now I don't know how to show the Ipad screen on the PC, as if it was a monitor / screen, so that I can then use Lync and share my PC screen with people virtually.
Thanks for any help! RegardsHi Rob - thanks so much for your help! Could you tell me what "air sever or reflector apps." are? and where can I look for information about them?
Do you use them on the Ipad or on the PC?
Do I need a cable too and which one?
Sorry... I am not very technical as you can see, thanks for your help.

Is the Duet app that supposedly connects a Mac to an iPad screen a scam?

You meant this? This is the first time I have ever heard of it, but I doubt that it is a scam.

There are other apps that "connect" an iPad to a computer, but those apps work over WiFi. -
I have a iPad and I connect it to my tv through hdmi but would like the sound to come out through the headphone socket, can I make this happen.
Go to System Preferences>Sound>Output and make sure that you selected the right output. I think if yo use HDMI you might not be abe to select another output.

FORCE IPAD INTO RECOVERY MODE
1. Turn off iPad
2. Turn on computer and launch iTune (make sure you have the latest version of iTune)
3. Plug USB cable into computer's USB port
4. Hold Home button down and plug the other end of cable into docking port. Do not release button until you see picture of iTune and plug.
5. Release Home button.
ON COMPUTER
6. iTune has detected iPad in recovery mode. You must restore this iPad before it can be used with iTune.
7. Select "Restore iPad"...

Today I was updating my phone to the newest IOS 7 and after it finished downloading. An error showed up on my screen telling me it was unable to update. So I decided to just unplug my phone and maybe do it later but on my screen I have a USB cord and the iTunes logo asking me to connect. So I hooked it back up and still at this point my iTunes will not connect and when I unplug the phone the screen stays the same. I have tried turning off the phone and restarting and both times the screen goes back to the connect screen.. How can I fix this?
I have tried the steps to fix it but no solution! Please someone tell me what to do!

5th Gen iPod freezes on "Do Not Disconnect" screen when connected to Mac
My iPod freezes on the "Do Not Disconnect" screen (partially backlit) when I plug it into my computer. I have a G4 eMac with standard USB connections. The ipod firmware is up to date.
This freeze doesn't occur ALL the time....just occasionally. The iPod does not appear on my desktop or in iTunes when this happens. I have to wait until the iPod discharges its battery completely before I can use it again (this sometimes takes a couple of days!).
Does anyone have any ideas? Or is anyone else experiencing this?
Thanks....

G4 eMac 700mhz Mac OS X (10.4.9) 768 MB RAMThanks for the replies.........I can't seem to find a solution to this....its annoying to say the least. Its just happened again this morning, though it's successfully sync'd on the last few occasions....it seems to be quite random.
One thing I've noticed is that it synced OK when iTunes wasn't open when I plugged it in. It appeared on the desktop, then I opened iTunes. This morning though it froze when iTunes was already open, so there may be an issue with iTunes (I updated this weekend to see if it was any different with the new version). I guess this will happen if you've got the ipod set to open iTunes automatically when connected too.
So, no solutions as yet.......I'm gonna get onto Apple to see if they have any answers. I'll get back to you all on this one.
PS: why no firewire capabilities on the new ipods?
