Blurry video from Isight, hardware or software issue?

The last time I used my iSight was a few months ago with 10.4.3 or 10.4.4. I have updated to 10.4.5 and my iSight shows a blurry stretched image with lines going vertical. I am not sure if this is just a coincidence, or if my iSight was damaged durring my time of not using it.
If any one has had this problem, or knows for certian that it is hardware, please let me know. Also, if there is a way to "rollback" the update for troubleshooting purposes, please let me know. Thank you.

 Hello CurtisP. Welcome to Apple Discussions.
I am using the 10.4.5 update with good results. If you updated properly, I strongly doubt that the update is causing your problem. It is possible that the download or the update itself did not work properly.
First, verify that you have not added other hardware or software since you last used your iSight that may have resulted in Possible hardware or software conflicts.
As noted in the "camcorder substitute" section of Using iSight, it is not unusual for people who store their iSights for long periods, particularly inside iSight's plastic shipping case or in places like briefcases or desk drawers that move, to find that their iSight has stopped working.
If the suggestions in How to test your iSight to ensure it is functional do not help resolve your problem, you might also want to try the 10.4.5 Combo Update as suggested in How I Update My Mac OS X before you see your Apple Service Tech.
The only way to "rollback" to an earlier version is to Reinstall Mac OS X to the installer version you own on disc. You must then reapply the updates that would take you to the version that you desire. Even if you want to use a version earlier than 10.4.5, I suggest you use that version's Combo Updater to get there. Using the combo will save you the time of upgrading stepwise, and it seems more reliable to me than using the "Software Update..." method.
Please let us know how it goes for you.

  • My IPhone 6 with AT&T is dropping 5-10 calls a day. Calling from same location as my 5S which never had dropped calls. Is this a hardware or software issue?

    My IPhone 6 128GB with current software using AT&T is dropping 5-10 calls a day. I am calling from an office with good signal strength and in the same location as i did with my 5S which almost never had dropped calls. Is this a hardware or software issue? Is this a common issue with the new IPhones?

    Hi jackneedshelp, 
    Thanks for visiting Apple Support Communities. 
    If calls are not going through on your iPhone 6, I recommend going through the troubleshooting method found at this link:
    iPhone: Troubleshooting issues making or receiving calls - Apple Support
    These steps can help identify and resolve the symptom that might be causing the connection issue.  
    All the best,

  • Lion 10.7 Only Boots in Safe Mode. Is This a Hardware or Software Issue?

    Hi. On my iMac late 2009 i7 8GB bought last March only. I reinstalled Lion (I didn't erase the whole disk because I have Boot Camp Windows and I have filed there) and it can only boot in safe mode if I use the Mac's built-in EFI bootloader (where you have to press option on restart) menu then press shift after choosing the iMac OS X hardisk. I've been trying to fix it for around 4 days now today. I'm tempted to take it to the authorized Mac shop but that could take weeks to months in our country. If I let it boot normally, it would seem to have a kernel panic and would stop at the white/gray screen. Verbose mode showed that is stopped at something 10 of these like: nstat fail.
    Is this a GPU hardware problem, specifically the 3D element of this 4850M GPU? I'd like to do load each kext, each extension manually but I can't find them in Lion. When I use the Lion DVD or the Lion Recovery partition, it's very sluggish, every click and process takes 20 seconds to minutes. If I try to boot in Linux, Snow Leopard DVD or Snow Leopard external hardisk, there seems to be a kernel panic. It's either just a black screen or a garbled screen.
    I want to erase/format the iMac's hardisk but in Safe Mode, it can't be mounted even if I use Disk Utility. If only there's a way to force it to mount, I can save some Windows 7 file to one of my external hardisk or flash drive. Does anyone know of an app or program that can mount NTFS files on Lion's Safe mode?
    If it's a Lion bug, has Lion somehow corrupted the Mac's built-in (hardware not the EFI partition in the hardisk) EFI or somehow corrupted the Mac or GPU's ROM? Could it be a new OS X virus? Should I then perform in Safe Mode to flash the GPU ROM and the Mac's ROM again (I have the latest)?
    Do you think if I erased the whole drive, reinstalled it again with either Snow Leopard (assuming it doesn't boot into a garbled screen) or Lion things will go back to normal?
    Has anyone experienced something like this? What was the culprit (was it a hardware or software issue) and what was the solution?
    Gbu.

    Hi thanks for all the concern and replies. I've tried all that.
    I had just got it back from the shop last Friday. It was there for around two weeks. It was a faulty GPU (when you see garbled display that's consisten when booting it the GPU). I have a strong feeling it's related to the Lion install 10.7 or 10.7.1 and may be similar to reports of Mac laptops overheating. It's good the GPU is removable, it might have taken 3 week or a month if it had been the whole board.
    It's a blessing in disguise though as with all or most cases because I also got to have the LCD replaced for excessive backlight bleeding (in my opinion), the dead pixel from the previous LCD isn't there anymore (though under the glass there're some smudges but nothing crucial). The backlight bleeding is still the same though in my opinion but at least it's new.
    It's a great thing I bought Applecare. I didn't buy it for the iPhone because that's more durable (my iPhone 3G's 3 years old now and it's still solid. Although there are scratches and a crack at the back at the bottom, got sqeezed under the table I think when I sat). I think Applecare is a good recommend for things that get hot like desktop and laptop Macs(are the iOS considered Macs btw?) which are twice or thrice the price of iOS devices.

  • Home button response after 8 sec after IOS5. so is it hardware or software issue ?

    Please help. My ipone 4 is just out of warranty. was working fine with 4.33. once upgraded to ios 5 . it slowed to 4-5 secs. I did a reset and restore it becomes worse.
    Now phone is alomost useless , kind of disappointing coming from an expensive apple phone. So is it  hardware or software issues ??
    Regards
    Bukohsk

    At this point, it's hard to say, but I'm not inclined to think hardware.
    Have you tried a SMC reset?
    http://support.apple.com/kb/HT1411?viewlocale=en_US
    This might be relevant for the Mac not going to sleep.
    Have you verified the disk and repaired if necessary?
    Have you tried resetting the PRAM?
    http://support.apple.com/kb/HT1379?viewlocale=en_US
    You might also try the steps in this article:
    http://support.apple.com/kb/TS1417
    My recollection--which may or may not be right--is that repairing the disk may cure the spotlighting problem. The other steps I mentioned are just general things that are often done when troubleshooting.
    Try repairing the hard drive, and post back if that doesn't cure the problem.
    Good luck!

  • RSAP (Hardware or Software issue ?) Apple Eng. please feedback on this ...

    Dear iPhone users,
    One of the things who is holding me back on buying an iPhone is the lack of support for rSAP. My car has it to provide phone integration but as far as I know iPhone doesnt support it.
    Is rSAP support a hardware or software issue ? Has the iPhone the capabilities to enable rSAP in the future ?
    I dont want to buy a WM6 phone ! HELP !
    Best regards

    It software. Apple will enable it if and when they want to.
    Aside from that, there is no information.

  • Strange Drive Behavior - Hardware or Software issue?

    Our xServe has three drive bays. Bay 1 is the system drive, 2 is our file data and drive, 3 is has an empty 250 drive.
    Over the network, users can access the file data, however when I attempt to open the hard drive at the server (by clicking on the icon) the window opens but it does not display all the contents. I get a spinning beach ball and am forced to relaunch the Finder. The same thing occurs with attached FW drives.
    Disk Utility and Disk Warrior show the drives to be fine (although I'm not sure I completely trust the reports).
    As a hardware test I swapped the data drive to bay 3 and the blank drive to bay 2. Clicking the bay 3 icon seemed to work initially until I tried to open bay 2 and got the spinning beach ball.
    I have repaired permissions on all the drives.
    It is not clear to me if it is a hardware or software issue. Any ideas on how to troubleshoot this would be a great help.

    Thanks for the reply, Camelot. This is a weird one.
    I don't know the exact number of files, but it only totals 84gb out of the 120gb available. The amount of data hasn't significantly changed recently and this problem is a recent one.
    I have let the beachball spin for several minutes and it doesn't resolve itself. I am afraid to let it go for much longer because I fear the data will get corrupted. Because of the external firewire drive issue as well, I don't have a recent back up .
    I have backed up the data in its current state to other networked computers and am doing a random test of the files to see if there has been any corruption, but with so many files it is hard to say.
    The whole thing makes me nervous, to say the least. I have years of troubleshooting desktop macs but the Xserve seems like a different beast so I'm wary of doing the usual types of troubleshooting. Guess it is time to call in the pros!
    Thanks again for your help.

  • IPhone 5 Hardware or Software issue?

    My iPhone 5 is just under a year old. Just recently I noticed that when I put the phone in silent/vibrate mode and then switch it back it doesn't revert back to normal.
    I am thinking the swith may not be working properly but I can turn it off and turn it back on and it works properly.
    I can't trace it back to the most recent software upgrade but it is possible that is the culprit.
    Is ths a hardware or software issue?

    If a reset and then if required a restore do not fix it likely a hardware issue

  • Hardware or software issue causing purple lines & no boot...

    I was watching a movie on my Mac Pro (2006) and suddenly the video stopped and purple lines went all over parts of the screen. I couldn't do anything, not even a force quit, I was forced to turn off the power.
    Upon restart, the Apple logo is showing the same purple lines, though the grey background was unaffected. After the loading, the logo disappears and then I get a cursor and a beachball and nothing else. Mouse input works, but otherwise the computer does nothing.
    I was able to do a safe boot and it works, but the purple lines still remain.
    Anyone else have this issue? Does it sound like hardware or software?
    I'm probably gonna transfer files and just reinstall snow leopard. I'm hoping it's not a dead video card or something. If that's the case, then it's just become a craigslist special... maybe $250?lol
    Any input/help is much appreciated.

    Actually, I have a Late 2011 Macbook Pro Quad Core Sandy Bridge that's mostly been sitting in my safe since I bought it in 2011 (insurance replacement form a Core 2 Duo era Macbook Pro that was stolen).
    That thing has always run circles around the Mac Pro. It may run at a slower clock speed, but everything about the Sandy Bridge Core i7 is superior to the now severely obsolete Woodcrest Xeons
    It's definitely served me well, it was my first Intel Mac, I moved from a Powerbook G4 1.5ghz to this, and it was amazingly fast, even running Adobe CS2 in Rosetta. But lately, for me it's been getting slower and slower. Any websites with flash are slow as molasses. I can't even make it through an episode of a show on the History or A&E websites without the last segment being a slideshow.
    I've recently switched to the Chrome browser, it's helped in usability, but it's still not ideal.
    I'll wait for a good deal on a 7300GT on eBay to get it back up and running. Still, I really like iCloud and all the integration that comes with the latest Mac OS releases, so it really is time for me to start using my modern Macs more. I was already heading in this direction. It's been a good system, but it's time has passed. I'm already moving my iTunes HD to my Macbook Pro, next I gotta get the files off of the Mac Pro onto an external.
    Maybe I'll just keep it around as a Rosetta system since that's the one area where my Macbook Pro falls short. I still use PPC apps once in awhile.lol

  • PC Card not recognized - hardware or software issue?

    Hello All,
    this is my first post to this forum. I own a PowerBook G4 (late 2005) since February 2006, but still do consider myself being new to the world of Mac.
    Most questions in this forum get good and detailed answers. That's why I hope someone here can help me with some issue regarding my PowerBooks PC Card slot. Thanks in advance for reading this.
    I can't get some special PC Card to work. I'm not sure if it's an hardware or a software problem. For now, I guess it's an hardware issue with the PC Card slot. Regarding this, my Apple Service Provider told me, they will charge me a fee of 90 (Euro-)bucks, if their result of checking the PowerBook is, that the PC Card slot has no hardware damage and needs no repair. I'd like to have some more certainty before paying this for no reason.
    Some facts:
    * The PC Card is an Option GlobeTrotter HSPDA 7.2 READY DataCard
    * This data card proved to work well in a linksys WRT54G3G router
    * I installed a vendor specific driver/kernel extension/whatever that came with this card
    * When the data card is inserted, it seems to get power from the pc card slot, since some lights on it start to flash
    * At the same time a message occurs in system.log:
    'Unable to create cardbus nub for socket 0'
    * The card +does not+ appear in System Profiler
    Provided that a pc card slot works correctly: Does system profiler at least displays an entry in section 'PC Cards', even if a certain card is not supported?
    I'd like to ask you to tell me what you think. Please make a guess, if it's an hardware or a software issue, and let me know for what reason.
    Thank you!

    Hi eww,
    thank you, any help/hint/idea is appreciated, cause I ran out of ideas myself.
    I bought the card from a company called nova media: http://www.novamedia.de/epages/e_produkte_gt_hsdpamac.html. Novamedia develops drivers and connectivity software for those data cards by Option, and sell them bundeled with hardware. So I'm pretty sure this card basically works on PowerBooks. Their support answered several of my questions, and even developers got involved, but at the end they couldn't say for sure if it's their drivers or my PowerBooks fault. They never had this kind of error before.
    Entry 'PCI Cards' in System Profiler shows 5 devices, no matter if the card is inserted or not:
    Entry 1 ... is a network controller
    Entry 2 ... Card: TXN,PCIXXXX-00, Type: cardbus, Bus: PCI, Slot: PC Card
    Entry 3-5 ... USB20 devices
    I had a look at the darwin source code (http://www.opensource.apple.com/darwinsource/tarballs/apsl/IOPCCardFamily-45.tar .gz) for the cardbus stuff and even found the log statement, but beyond that, got no clue from it. Unfortunately I'm neither a C programmer nor a device driver expert.
    I guess, the best thing is to bring the PowerBook to my Apple Service Provider now. I'll leave a message here in 1 or 2 weeks what the results were. Currently I need my PowerBook very bad and can't do without it for several days.

  • Headphone jack no longer working - How to test if it is a hardware or software issue?

    Hi, my headphone jack fairly suddenly stopped working. The speakers and the sound are fine, but when I plug my headphones in nothing plays. I see that the computer does recognize that headphones are plugged in, and it does change it to "headphones" instead of "speakers" under sound properties.
    I don't remember installing any particular updates, but I did recently swap out my 4GB RAM to an 8GB stick. Not sure if the tech shop did something that might have ruined it. Does anyone know of a way that I can test whether it's a software issue or a hardware one?
    thanks

    Hi @svltn,
    Welcome to the HP Support Forums. I saw your post regarding your concern about the audio jack not working. There is a good chance that is it not a software issue because then you won't get any sound from the speakers either. You can try setting the headphones as the default audio device if you haven't already. This third-party link will show you how. It is for Windows 7 but if you are using Windows 8 just search for Control Panel from your main tile page and the rest is the same from there.
    Have you tried a different set of headphones or the current headphones in another device to see if it is the headphones themselves that are broken? I don't think it is the RAM but if you still have the 4GB RAM put that back in and see if the headphones start working again.
    Please click “Accept as Solution ” if you feel my post solved your issue.

  • Live video from isight embedded into keynote slide

    I have been trying to figure out how to embed live video from my isight camera into keynote. I have tried creating a stream from quicktime broadcaster and import the .sbp file into keynote, but it will not except the stream file. I did not know if there was another way to do it besides the stream or if perhaps I could use another program to help input the video.
    My ultimate goal is to be able to present slides and have a live video from my isight during the slideshow on one of the slides. I guess if there is some other way to get both the slideshow presentation and video on the presentation screen without any program headings, in a clean fashion, that would be acceptable too; even if a different program was handling the video and it wasn't technically embedded.

    Cool, I can see me using this - need to properly test with http://b-l-a-c-k-o-p.com/CamCamX.html#upgrade
    this allows you to choose video sources to play - so i'm betting it will allow video cameras to be used - so it ought to be possible to do live demos/illustrate slides with 3d objects etc ... cool - suspect voice syncing still might be an issue. And KN record doesn't work properly if you have a live movie - it just shows the camera content that's live ... (if you follow me...)
    PS Almost forgot - it will do one of the things I was so desperate to achieve: It would allow you to have a window on the screen with a live feed of a signer for those who use BSL and other sign languages - that's really important. And if you needed to you could use two projectors (see other thread on multiple screens) and put the signer on a nicely designed screen all of their own. WOW!!!

  • Hardware or Software Issues?

    I've been having some odd problems with my iPhone 4S these past few weeks and am wondering if these are hardware or sofware problems.
    I'll notice that randomly when listening to music, the volume will decrease on it's own own to almost nothing. I'll turn it back up, and a few minutes later, the same thing happens again.
    I'll also find that sometimes the screen isn't very responsive. I'll need to touch icons a few times before they launch or folders close.
    Also, this morning while browsing through Instagram, the home/lock buttons just stopped working. I was still able to navigage within the app no problem, but I just couldn't exit it or lock it. I did finally get it to reboot by holding down both buttons for about 10 seconds.
    I've had every single iPhone since the first one and never experienced these issues. Also, I'm inclined to think it's more hardware than software because these issues just started popping up a few weeks ago and haven't been here from day one. I've done a restore and the issues still persist.

    Hi Ralph,
    Yes, I've done all this.
    I took it to an Apple store last week (just as a walk-in) and was basically told to do the restore and come back if it's still acting up and see a Genius. I went through the whole restore process and while using it this past week I'd see the problems come and go.
    I'm going in later today to a Genius appointment, but I'm afraid that because the problems pop up randomly it'll be hard to recreate it for them. I'd really like for them to just swap it out with a replacement. Is this likely to happen?

    Hey KoreanSasquatch, 
    Thanks for contributing to the Apple Support Communities. 
    If your MacBook Pro is turning off unexpectedly, isolating the issue to hardware or software is a good place to start. 
    You may find the tips in this article helpful with isolating this behavior:

  • My battery is draining! Hardware or software issue? iphone 4s ios 5.1.1

    My iphone 4s battery is draining.  I have turned off all push notifications for email and the like. I have no apps running in the background and yet after 10 hours of idle time i go into settings and my phone reports "9 hours 45 minutes of standby" time and "9 hours and 15 minutes of actual usage" time (during the same interval).  I restored my phone via itunes twice starting as new iphone (I.E. having to re-download everything manually WITHOUT the starting from backup). I went to the apple store and they told me to just restart it however this has not been effective. IS THIS A HARDWARE ISSUE OR A SOFTWARE ISSUE?????

    Oh Yeah i just check it!
