Mac HDMI to TV suddenly stops working

10.9.4 mavericks macbook pro retina to TV via HDMI
using an HDMI cable to watch movies on my laptop macbook pro retina.
was working this morning, and watched a movie. then I go to work, and come back and now the exact setup is no longer working.
it does not show any display in the preferences menus, and the TV is just blue without any input.
cable is secure, nothing has changed. nothing.
edit: actually I did pull the HDMI cable out while the two were connected this morning.
tried restarting, reconnecting, nothing
... very frustrating, no idea why computers suddenly stop working for no reason whatsoever. maybe someone hacked my computer this afternoon while I was gone? it's just a random failure.
Any help?

Gmail suddenly stopped working on my mac

Please...Help! My gmail suddenly stopped working on 9/9/12 via my macbook pro. How do I get it started again? It is working online and on my iphone, but not on my macbook....

Yes I am using Apple Mail. The account settings haven't changed and were working fine. Then suddenly gmail emails stopped coming in on the mac. I can still get my gmail online and on my iphone, but not the mac. Frustrating....

My Mac mail suddenly stopped working

My Mac mail suddenly stopped working. The last email I have is from 4:40 or so this morning and I know that I have email because I can get it via a webmail program. It stopped working on my iPhone 4 too. Any ideas? It's IMAP if that means anything. Thanks.

I'd recommend also reposting in the Snow Leopard forum because Mail is part of SL If both sending and receiving is not working then contact your ISP and see if they have any known issues. If they don' t what I've found to work is removing the account in Mail and then recreating it.

MY iPhone 5C suddenly stopped working. It wont connect to my Mac and repeatedly reboots from the apple Logo when plugged into the wall. Help!

MY iPhone 5C suddenly stopped working. It wont connect to my Mac and repeatedly reboots from the apple Logo when plugged into the wall.
There is no water damage or anything. I got that checked at the Apple store. I also have Apple Care + but didnt let them give me a new one yet because I have photos on this that I have no yet backed up that are very important. They are the last photos I have with my grandfather. Can anyone help me. Please!

If the phone shows the "connect to iTunes" screen, the data on the phone is most likely lost.
Connecting in recovery mode is your only chance to use the phone again, besides getting it serviced by Apple.

TS2198 ical (the calendar program) that came with this apple mac pc suddenly stopped working, then disappeared from the computer, from the desktop where I have been using it for the past two years, without trouble, then from the list of applications. . .

ical (the calendar program) that came with this apple mac pc suddenly stopped working. When I pulled the icon from the desktop, it then disappeared from the computer.I have been using it from the desktop for the past two years, without trouble. It has uninstalled itself, without my intervention and has eradicated all traces of it, including all my entries from the computer memory. There is no program in the applications list. Can you say why this may have happened please?

I opened one of the .calendar folders. There was a folder named Events which had either one or some files ending .ics. I opened several of these, which put up a dialogue window showing some parameters with data strings attached as follows :-

My mac pro suddenly stops working (2011), connection to the monitor stops, but de tiny light on computer still on and all sound stops. what's the problem?

my mac pro suddenly stops working (2011), connection to the monitor stops, but de tiny light on computer still on and all sound stops. what's the problem?

When the display turns off, it is not clear whether the computer has halted, or whether the display subsystem has failed.
Those tests determine whether:
a) Your Mac software had stopped working OR
b) Only the display had stopped working
If the pressing the Caps lock light on the keyboard lights the Caps Lock light on the keyboard, some software is still running -- your Mac has not halted.
If pressing Control-Eject on the keyboard, followed by the Return key shuts down your Mac, the software was still running.
¿Software was still running?
--Yes, the problem is ONLY in the display subsystem
--No, this is a computer-wide problem such as a kernel panic

Mac mini server has suddenly stopped seeing one or the other bluetooth devices! Batteries have been changed and they will connect to an older Mac mini. Server will now only see one or the other but not both.

My Mac mini server has suddenly stopped seeing one or the other bluetooth devices, either the wireless keyboard or the mouse( both apple products) have tried new batteries, at first it was the mouse that stopped responding, but upon rebooting the computer now the keyboard will not respond and the mouse works. Both work fine on an older Mac mini that I hooked back up to check.

There is absolutely no reason why they should not bothe be able to connect to your WiFi network. The easiest place to start would be to reboot your router. Unplug it for about 30 seconds and then plug it back in again. I would also restart both the iPad and the iPhone.

Firefox 3.5.25 suddenly stopped working, have old computer this is as high as I can go

I have a mac powerbook about 5 years old. The only version of FF I can use is 3.6.25 and have been using it all along. 3 days ago it suddenly stopped working. I lost my igoogle page. Icannot sign in as the button does not work. When I try to search nothing happens. I reinstalled it 3 times, still nothing. Works fine on my ipad2.

It's tricky to try to troubleshoot this one as 3.5 isn't really supported anymore. However, as you reinstall Firefox, all your settings are actually still kept in your Profile folder, so if it's related to your settings, reinstalling won't fix the problem.
What you could try is creating a new profile and see if that solves it -- note however that this will be like installing a second copy of Firefox and you will not have access to any of your bookmarks, passwords, etc. It is basically like starting from scratch (though your information is still kept in the original profile -- they can both coexist).
This article covers the procedure of creating a new, second profile: https://support.mozilla.org/en-US/kb/Managing-profiles?s=profile&r=0&e=sph&as=s

My Mac Pro (2006) has suddenly stopped sending signal to the display monitor.

My Mac Pro (2006) has suddenly stopped sending signal to the display monitor. It coincided with plugging in an Epson printer via usb - while the system was running. Pretty dumb maybe? Could I have damaged the video card? Anyone ideas? Thanks

Howdy Le Batch,
I was looking into the issue you are seeing here, and came across a helpful article for this specific situation. It's named Apple computers: Troubleshooting issues with video on internal or external displays and can be found here:
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.
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 system
You 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.

Sterling

FTP suddenly stopped working

Today, all my FTP connections have suddenly stopped working. I thought it was a problem with FileZilla, but have since tried 4 or 5 different FTP clients and none of them will connect to anything. Sometimes the connection just times out, and other times it goes through all the authentication and login seemingly successfully before the message appears: 'Critical error: Could not connect to server'
I'm using a 2011 MacBook Pro, upgraded to Yosemite about a month ago (and have been using FileZilla on a daily basis since), but otherwise I can think of no hardware or software updates that have been made.
I've tried restarting my router and my computer. I've also checked the Mac firewall, which was already switched off. After googling the issue, I read that turning off 'passive mode' might fix it, but it doesn't.
I haven't a clue how to go about fixing this problem!
Any ideas?

Ask in the DW forum and be much more specific about the requirements for your FTP connection like its ports, TLS settings and so on.

ISight suddenly stopped working

My iSight suddenly stopped working in the middle of a Skype connection. It had been working correctly: my contact heard me and saw my image. Then, the sound suddenly was lost, and after that the image. The green light on the iSight went off. If I plug the firewire cable into another port, the light comes on for a few seconds, then goes off. The iSight is identified in About This Mac. I took the iSight to the local Genius Bar, and it worked perfectly on 2 other Mac's. I was advised to re-install the OS with archive, but isn't there anything more simple?

Hello George,
... isn't there anything more simple?
Here are some things you can try.
(1) If you used your own iSight's cable when you tested your iSight at the Genius Bar, you know neither the cable nor your iSight is the problem.
You can test your iSight with other applications to determine whether you have problems with more than one. Also, consider the link there to Apple's "iSight: How to Troubleshoot" suggestions.
(2) If your only problem is with Skype, consider reinstalling Skype or check out Skype's great Help section. Skype even hosts its own discussion forums dedicated to Skype specific issues.
(3) If your iSight has problems with more than one application, consider whether your Mac OS X Maintenance is up to date. Maintenance is the first thing I check when I begin to experience minor problems or system slowdown.
(4) If your problem persists although your OS X Maintenance is current, download and apply this Mac OS X 10.4.8 Combo Update (PPC). Finish with another Permissions Repair and check your iSight again.
Users have reported fixes to a variety of audio, video, connectivity, and software conflicts and unreliability issues after properly applying Combo Updates.
The Combo Updater will be much simpler than an A&I reinstall.

AOL suddenly stopped working

AOL suddenly stopped working on my iMac. I have tried trashing the preference folder, and also trashing and reinstalling the software. Every time it tries to open I get a message that the program has "quit unexpectedly". Does anyone know what to try next?

Hi Again Michael!
I'm happy that worked!
TO REPAIR PERMISSIONS ON THE STARTUP DISK
1.Open Disk Utility, located in Applications/Utilities, and select the startup disk in the left column.
2.Click First Aid.
3.Click Verify Disk Permissions to test permissions or Repair Disk Permissions to test and repair permissions. (I never "Verify". Just run "Repair".)
Rerun RP until the only message it reports are the ones listed in this link:
Spurious Permissions Errors Using: 10.4.x
When "Repair Permissions" is complete. Quit "Disk Utility".
Thank You For The Star!

Mic suddenly stopped working

Okay so. I have a Turtle Beach Ear Force X12 headset which has been working great since I got it a couple months ago, well today it suddenly stopped working skype says my mic is muted and it's not, I can hear myself through the headset which means it's on and at least working but apperently it's my computer that's not picking it up and I have no idea what it possibly could be, I'm on Windows 7 btw.
Also skype kept moving the mic volume thing all the way down but I don't know if that's related at all.

When I make a call my mic doesn't work. Looks like I'm not the only one experiencing problems. Skype is slow and often won't even hook up. Tried my wifes mac with same result, my blackberry phone same result. I've become aware of how dependend on SKYPE i am.
