Latest OS X update disabled HDMI signal

Updated OS from mountain lion to mavericks with no problems.
Apple pushed an update to Mavericks which I installed last night and it disabled my mac mini's (i5 processor) HDMI output (sound & video).
I did a hard shutdown and reboot but still no display on my 47" LED TV.
It was working perfectly before the latest update. Now what?
Sounds like I would need to take it to an Apple store and have them revert it to the previous OS if possible.
I thought updates were supposed to improve performance not hinder performance.

Does it boot from the Restore Partition?
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Windows automatic update disabled HDMI.

I just purchased a new Pavilion 15. For 2 days it worked perfectly hooked up to a TV via the HDMI connection. Last night windows (8.1) did an automatic update and following that it no longer recognizes the HDMI port.
I have read the trouble shooting. I tried recovering the drivers but gave up after half the day was wasted on no progress.
I called tech support and was not given a simple answer either.
Is there a simple and quick solution?
The Best Buy I purchased it from is less than 5 minutes away from me and will refund it as it's only a few days old. Is that my quickest solution?

Hello! The solution to this was already given at http://h30434.www3.hp.com/t5/Notebook-Display-and-Video/HDMI-output-not-working-after-Windows-8-1-up...
I hope this helps!

Latest desktop viewer update = disabled folios

I just installed all of the updates needed for the Adobe Viewer (released 9/17/12). Now that I have installed the updates, the desktop viewer (which previously worked with my apps) now has nothing showing in the browser window. I received the email that said I needed to update a valid 'Application Name,' but the desktop viewer has not been working with any name that I've tried from my folios. Where can I find the 'Application Name' that I need to enable my desktop viewers? Is there a setting that I am missing in my preparation??
Thanks for any help!!

Welcome to Apple Discussions.
Some users have experienced help by installing 10.3.9 Combo Update. Remember to Repair Disk Permissions (Applications > Utilities > Disk Utility) before and after applying the update.
Good luck.

HDMI Signal Issue with LG TV

Has anybody seen issues with ATV and LG LCD TVs ? Have mine hooked up to input source HDMI1 on the LG, but when switching to HDMI1 from DTV the LG shows "no signal". ATV is on, and switching the TV off/on again shows the ATV menu and all is well..just an annoyance really but would be good if it could be fixed. Have tried HDMI2 source and same issue occurs. I think its a TV issue not an ATV on. ATV running latest s/w update.

I will definitely wait for the apple tv updates, as always. But I thought I'd pass on this interesting piece of info that may only cloud up our deductions or offer potential solutions to people's woes ! For grins, a co-worker loaned me a DISH Network thick orange HDMI v1.3 cable to try out. So....when I got the NO SIGNAL on the AppleTV while hooked up to my LG 720p Plasma via HDMI1, I swapped to the new cable. I got a signal. The AppleTV screen saver was activated by that time. So, I put back the suspect cable...leaving the TV selected to HDMI1, NO SIGNAL. Hmmmm.....put back the orange cable....signal was back. Then, put back the suspect cable....NO SIGNAL. Then I tried my other known working HDMI cable (also a Philips SWV2432W/27 6ft which has been used on an LG BluRay player to LG TV via HDMI2. I had a signal. I put back the original suspect cable...NO SIGNAL. Wiggled it about 6 inches from the AppleTV connection and I had a flash on the screen and momentary video...then NO SIGNAL. I wiggled it a little more and had a signal that stayed. So...my conclusion....is that given this evidence....it is entirely possible I have a bad intermittent cable. So, tomorrow I head back to Fry's for a replacement cable.
On the other hand, I can honestly say that I wouldn't be surprised if the issue repeats, given that I really didn't get any extended viewing in while performing this experiment. But, the experiment and the "random no signals" I got a few days back before going strictly component, could totally be explained by a bad cable.
I'll let everyone know my results with the new cable.
Also...from what I've gather on those HDMI settings, under Video and Audio....I think the HDMI settings are strictly for color boost/subtraction, etc. I don't think I've read definitively that they are for handshaking.
If it is the cable, I can just hear Video Store Salesmen all over the world saying "Now you know why you need to buy the $50 HDMI cable!" <No, thanks, I'll stay with the reasonable less than $20 cables>

I updated my iPod touch 4th generation from the latest iOS 4 update (i think maybe iOS 4.3.5 or something like that) to iOS 5.1.1 and my Photos, Videos, contacts, music, App data, etc. was deleted. How can I all the data back?

I updated my iPod touch 4th generation from the latest iOS 4 update (i think maybe iOS 4.3.5 or something like that) to iOS 5.1.1. I updated to iOS 5.1.1 on a Windows XP Home Edition with the Service Pack 3 installed on the Windows XP (which I believe is the latest version). After updating, I unplugged my iPod from the computer. I saw that all my photos and videos were on my iPod, but there were no apps. A window popped up and told me to enter a passcode for my iPod. I entered a passcode. I then locked my iPod and entered what I thought to be the correct passcode, but my iPod remained unlocked. Desperate, I tried many passcodes with failure. After a while, my iPod became disabled for a long time. I decided to reset my iPod. After I reseted it, I chose to reset from my earlier back up. After reseting, my computer loaded on all my apps. But, when I started using my iPod, I realized all my photos, videos, music, app data (like game saves and high scores), etc. were gone! I have no idea what to do and I am very stressed about this! SOMEONE PLEASE HELP ME GET ALL MY STUFF BACK!!!!!!

Go to iTunea>Preferences>Devices and see if there is a backupright at the time you did the update. Then try restoring from that backup. If the apps are in your iTunes library, any app data will be restored to the iPod.
When restoring from an iOS 4 (or later) backup, if the device had a passcode set, iTunes will ask if you want to set a passcode (and remind you that you had protected your device with a passcode). iTunes will not ask you to set a passcode when restoring from iOS 3.x and prior backups.
Therefore, remembe the passcode that you enter this time.
It appears that if you restore from a backup, that backup is not subseqyently overwritten by the next backup.

I cant seem to download and install the latest iphone software update. I have tried since the release and have been unsuccessful on more than 7 occasions and lost all the data on the process. Anyone have that problem an how do I fix this problem?

Hi
Thanks but I have tried doing the above - when I said 7 times I was modest, its more like 15 times.
And I am referring to the 5.1 software update. I dont have wifi so I guess I will have to try that seeing that my husband also has the same problem - he has also tried downloading several times. It always times out en says that the connection is lost but yet there are always an internet connection and a decent signal once it stopped. Think it said error 32052 or something!
I am disappointed because the update includes inprovement on the battery life - did you guys notice any difference?

How to uninstall the latest Flash player update

After I installed the latest Adobe Flash update, I am getting nasty messages when running flash embedded applications from Ms Office:
"this document contains embedded content that may be harmful to your computer"
I tried to enable All Active-X and all Macros without notification in the Office Trust settings, but it dod.t help.
How can i uninstall the latest Flash update and revert to the previous version?
Thanks!

I've fixed the issue applying the following steps:
1. Uninstalled Flash player with the Adobe uninstall utility.
2. Downloaded and installed the version 11.4 from the Flash archive here.
It seems that the 11.5 works fine as well. Actually, Adobe should fix the issue asap, because it will effectively ruin hundreds of office applications using flash.
Here is the thing. I should launch a standalone application from MS Excel. That application incorporates 30+ flash charts. To pass the Adobe warning message I need to click "Accept" 30 times which is insane. I don't see any other ways of disabling it, because even allowing all macros and active-x in the Excel trust center doesn't help.
Anyway, this Adobe "innovation" doesn't look right at all. I do hope someone from Adobe development team will see this and address the issue. Otherwise people will have stick to old versions and never update Flash.

KDL-55v5100 dropping HDMI signal

I am having an issue with my KDL-55v5100 where it drops HDMI signal speratically and the screen goes black and posts the HDMI 1 lablel then comes back on after about 5-10sec.
The TV is just over a year old. I have run a firmware update on the tv recently which I thought fixed the issue but it appears to have come back. I also have had my home theater system replaced becasue I thought this was causing the issue. It seems like that wasn't it.
I have my sataligth reciever plugged directly into my TV's HDMI port and this is happening again.
I'm not sure what to do at this point has anyone had this issue with this TV?

I have a KDL-55V5100 that we bought in December 2010, We did not buy an extended warranty. After only a few months, there was no signal from the cable. Sony sent us a USB flash drive to update the operating system and that worked just fine. Just a couple of months ago, we started having the problem with the tv shutting off for 1-3 seconds and then showing the HDMI input message. It happens sporadically with no pattern. I called Sony for help and was told that since it's out of warrenty, the only help available is online. I haven't found any suggestions that help. Thinking I'll never buy another Sony product!

HDMI signal not compatible with my Sharp TV

After the recent updates of my playstation 3 firmware, the HDMI signal is not compatible anymore with my Sharp Aquos LC-42A65M keeping in mind that I've tried video reset options, factory reset for both TV and PS3, changing HDMI cables, using different HDMI ports. My tv set works with any HDMI connection from other devices but PS3, and at the same time tried PS3 on other TV set and it works fine..I've searched the Internet for long time for any solutions but failed so far. My question: How can i make ps3 HDMI signal compatible again with that particular tv set. And by the way both were working together without any problems before the updates.

Hi,
g series has dozens of models, which one is yours ? Re-enable HDMI sound may help.
Right click the speakers icon,
Select Playback devices,
Right click HDMI sound,
Enable it.
Hope this helps.

Apple TV2 Just Disappeared from Remote app on iPad and iPhone after latest Remote app update

I Have used Remote app on my iPad and iPhones to control my ATV1, ATV2, and ATV3 for years. After the latest Remote app update ATV2 has disappeared from tRemote, and I can no longer find a way to connect it. Any advice about this?

Brilliant. Restarting did the job, and all is well. Since I have recommended this to others with other ATV problems, I'm a bit embarrassed that I didn't try it myself at the outset, and would probably have come around to trying it later, but you saved me some time. Thanks.

After installing the latest itunes/quicktime update, I can no longer access the itunes store and my iphone does not complete syncing. What can I do to fix this?

After installing the latest itunes/quicktime update I can no longer acces the itunes store nad my iphone does not complete syncing. What can I do to fix this? I have tried uninstalling and reinstalling itunes. I have uninstalled and reinstalled windows updates. I have checked the firewall settings. what else?

The problem is with version 10.4.1. I had to reload 10.3 to get it to work. The recommendation from a previous poster worked for me. Here was their list of steps:
Go to Control Panel>Programs>Uninstall
2. Uninstall the following Apple programs in the following order:
     a. iTunes
     b. QuickTime
     c. Apple Software Update
     d. Apple Mobile Devices Support
     e. Bonjour
     f. Apple Appllcation Support
3. Reboot PC
4. Find, Download and Install iTunes 10.3 (you can find it at FileHippo.com)
If you start iTunes now you will get an error message saying that the current iTunes library was created by a newer version of iTunes. To correct this:
5. Go to your Music>iTunes folder and delete the "iTunes Library.itl" database file
6. Within this iTunes folder find and open the "Previous iTunes Libraries" folder and locate the most recently dated "iTunes Library (date).itl" database file.
7. Copy and Paste this file back into the iTunes folder
8. Rename this "iTunes Library (date).itl" file by removing the date. It should say "iTunes Library.itl"
9. Reboot PC

HT202157 since latest ATV software update i can no longer do home sharing or air play

since latest ATV software update i can no longer do home share or air play

Try restarting the Apple TV by removing ALL the cables for 30 seconds, or resetting it using the reset option under general. You should also try restarting your router.

I downloaded the latest Firefox security update and my computer will no longer access the internet in any fashion, despite the fact that I'm still connected to the internet. Other browsers no longer work either.

Immediately after I downloaded the latest firefox security update my computer will no longer access the internet. I still have a fine wireless connection but Firefox, Internet Explorer, Itunes, and every other program will no longer access the internet, saying there is a connection error. I even tried restoring my system to a previous date but it said that a security program was preventing it from doing so.

What's the security program called? Is it '''Win 7 Security''' by any chance? There's a rogue AV app that will prevent internet access by that name. It comes in many different flavours, but it's basically the same product with different names depending on the operating system its aimed at. See screenshot.
Do you have another computer you can use to download Malwarebytes? Or can you get a friend to download it for you and copy it to a USB drive? Download from here: http://www.malwarebytes.org/products/malwarebytes_free
You can use the USB drive to transfer the program to your own PC and then install it.

I am trying to download latest Apple Itunes update to my Toshiba laptop and got the following system error message: APSDaemon.exe

While trying to download the latest Apple Itunes update to my Toshiba laptop I got the following
message: APSDaemon.exe system error.
I uninstalled Itunes and tried again, but got the same message.
Help, please

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.
