Desktops :: G5 ISight IMac Shuts Itself Down (OS 10.5.8)
Apr 19, 2010
Have a 17" G5 iMac iSight (OS 10.5.8) that works normally for several hours and then the CPU temperature suddenly spikes and the computer shuts itself down. When I check the Temperature Monitor (application) history graph, it shows normal temperatures and then a spike. There are 3 fans and I don't know which is failing or whether there's something in the temperature sensing that's gone haywire. My only solution is to do a forced restart. By this time, things have cooled and it will work for several hours.

I have an iMac G5 iSight. When the power button is pressed there is no sound and a white light flashes, but nothing else happens. I tried the power reset method and replaced the power supply, but the same thing happens. The white light just keeps flashing.

My Mac attempts to start up and automatically shuts down on it's own. It continues to start and stop for several minutes and finally boots up. Once it's up it works OK. I've had it in to the Mac store and they tell me it's probably the power supply, but after leaving it on all weekend it seemed to work OK so they didn't do anything. After I brought it home it is still acting in the same way. It's only on trying to start up that it cycles through the start - stop action. Once I turn it off it's the same problem on trying to start again. Does this sound like a power supply problem?

Recently my iMac had been experiencing problems, I took apart and checked everything and put back together. Problems were gone but the screen suddenly started gradienting from brighter on the top to darker on the bottom. Brightness overall is also lower now.
My question is what can be creating this? The black tape that was around was ripped, I've heard it's creating static isolation, can that be it? Also I possibly pulled power cord too hard, can it be possible that display is not getting enough power?

As of yesterday, I'm having problems with Facebook and Chatroulette not recognizing the built-in iSight on my iMac. The camera is recognized on Skype, Quicktime, Photobooth, iChat, etc.
Has anyone had the same problems and what did you do to fix it?

I purchased the last generation iMac G5 when it came out a few years ago and I recently tried to sell it. I sent the item to the buyer and he said it would not start. The Apple logo or for that matter anything would not come up. He brought it to the Geek Squad at Best Buy and they said it was an issue that would most likely cost over $500 in repairs. I just got the computer back in the mail and all that happens when the power button is pressed is the white light on the front lower right hand corner comes on for a second, then the machine shuts down. You can also hear the machine begin to start for about two seconds, then it shuts down. Any ideas as to the problem and whether it is fixable without expensive repair costs?

I read a few posts about dead pixels on the iSight, so I thought I'd post this picture to see what other people think. This is a screenshot straight from Photobooth, showing the image from my iSight when the black cleaning cloth is held up to it. No, those marks are not dirt (on the outside anyway). Other that this, my iMac is fine with the exception of a single dead pixel (I thought this was a thing of the past, but oh well) and I'm not 100% about whether or not I have the yellow screen issue, so I'll ignore it for now.

Besides putting a piece of paper over the iSight, is there a way to manually disconnect it so that no one can remotely login from the outside and view it? I am assuming that even a firewall would not be enough. This news story made me think about it: [URL]

My iMac (21.5") turn off by itself and it doesn't turn on until I unplug the AC from the back and let it rest for at least half hour!!! If I try to turn it on I only get fan and drive noise but no screen at all... The longest time I let it rest, the more time that I can use it. I already reset PRAM. I'm runing 10.6.3 and the biggest software I use is ArchiCAD 13...
Does anybody have a similar issue with his/her iMac?
PS. Sorry, I don't speak/write good English but I did my best...

I'm new here, but not new to the Mac world. I own an intel iMac and while I was attempting to restart it on Sunday night it went into a gray screen with the box asking me to shut and restart in several languages. I did and still get stuck on that page. I did a PRAM reset and that didn't work. So I used my start up disk to get to the disk utility and my HD is fine so I used an external drive to install the OS on it and reboot from and reinstalled from TimeMachine (only problem is the last time I backed up was 5 months ago)Again I checked my internal drive and everything seems okay, but I cannot reboot from it. BTW, I've OS 10.6.2,

I will be traveling overseas soon, I have a PowerBook and an Intel iMac, I want to be able to access some files from my PowerBook while I'm away, and at the same time, can I use the iSight in my iMac as a surveillance camera? Unacceptable answer: "use the search function, has been covered several times!". Acceptable answer: "go to bed, you obviously need some rest".

According to the Guides section of the forum, the built in iSight cams use a USB bus connection to the system. Has anyone ever "harvested" the iSight from broken iMacs or MacBooks and wired them for external use? I would imagine that they'd make great fixed focus surveillance cams.

iMac G5 17" iSight
1.83GHz
2GB 667MHz SDRAM
My monitor has turned off and will not come back on. Clicking noises and a slow operating speed occurred a few days ago. I have tried this SMU Reset Process below:
from [URL]
1. Turn off the computer by choosing Shut Down from the Apple menu, or by holding the power button until the computer turns off.
2. Unplug all cables from the computer, including the power cord.
3. Wait 10 seconds.
4. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
5. Let go of the power button.
6. Press the power button once more to start up your iMac.
Upon completing step 6, the computer turns on only to feature the fans spinning at maximum speed and still no monitor display.
Is this a Logic Board issue? The iMac was purchased for $1700 in 2006. Would repair costs be so high that just buying a new iMac would be the better way to go?

My mother's iMac G5 began this just two days ago. It turns on fine, but once is reaches the apple logo with the spinning wheel, the screen begins to exhibit what is shown in the pictures below. It first started when I opened an .AVI I received in an email from my uncle. When the file opened, the whole screen(within about 2 seconds) had discoloration and macro blocking spread from the center of the screen outward. After this I rebooted, tried again, and when I opened the file, it did the same thing. Now I can not even reach the log in screen. And after the screen has been in this state for a while, it may go blank and the fans run at full blast. I've opened the same file on a PowerMac G5 and a MacBook Pro with no problems.

The iSight just won't focus properly. If I hold my hand right up close to it it picks it up fine, but just a normal face shot it's so bright you can hardly make out the face?

I am running leopard on an iMac 24" and am having trouble getting my iSight camera to record audio on 2 channels. I have changed my audio input to line in (inbuilt input) in order to record using a better microphone than the inbuilt one in my iMac, and am running a Shure microphone into the input in the back of my iMac via XLR to 1/4" stereo jack cable and then through a 1/4" to 1/8" stereo jack adapter. However when recording video in Photo Booth, iMovie etc. the audio only plays back out of the left speaker. It is not a problem with the output because all of my other sounds (music from itunes for example) play fine out of both left and right speakers. I believe I have run everything into the computer just fine and I can get 2 channels when recording like this in Garageband and Logic.

I have a 20" G5 iMac with iSight that will not power up. No chime or screen activity. The first diagnostic LED is on which I assume means the power supply is OK, but the other LED's are off. Can any recommend what trouble shooting steps to take next?

Im looking to upgrade my iMac G5 (iSight) 17" 2.0Ghz Intel Core 2 Duo to a SSD hard drive. How much speed can it handle, the available SSD hard drives have SATA speeds of 1.5Gb/s, 3Gb/s and 6Gb/s. I would like to get the 6Gb/s one but only if it can accept that speed.

I have a 20" G5 iSight iMac running OS X 10.4.11. The optical drive will not recognise any discs other than original audio CDs - it takes a long time to do this, and is very noisy whilst spinning. Any other DVDs or CDs (including ones burnt on the same machine) are just ejected after about 30 seconds of whirring and do not appear to be recognised anywhere by the computer.

The camera had been working fine with FaceTime, Photo Booth and Skype under 10.9.4 and then something happened. I run FaceTime and the camera screen comes up, but it's black with no sidebar. I had this happen once before when the serial number hadn't been put back after they replaced the motherboard. It's back in now and was working fine. I did have to install Google hangouts plug in, but FaceTime was working fine after that and I've since uninstalled it after FaceTime stopped working and it still doesn't work.
I did have AirParrot and SoundFlower installed which the camera worked with, but uninstalled them as I saw something about a possible problem. I've reset SMU and PRAM, nothing. he mac sees the camera as being there so it shouldn't be a camera problem, but the apps while seeing the camera aren't getting any input [and no it's not blocked. ]
