Have been searching all over for My 20" iSight G5 iMac won't start.
Already tried:Removing power cord Using other power cord Inserting power cord while holding down power button Holding power button for 6 secs+ Plugging cord to wall outlet Begging and praying to the mighty white apple.
A friend of mine has a G5 iMac that won't start. When you press the powerkey it tries to start, the power light glows, the screen goes grey and after a while the fans start whirring. Occasionally (twice in the past couple of days) it has started up, but it froze after a while. Other times the apple logo appears and the gear wheel starts turning but then it freezes.
I have tried booting from DVD, holding down the shift key and have taken the back off and pressed the wee button on the board.
Since my friend has the same model of iMac as me (they were bought at he same time and place) i tried the RAM that I took out of mine when I upgraded.
i have an imac here which won't start when i push the power button. nothing happens. there is no noise, no fan, no flashing on screen or something else. i already opend it and checked the 4 LEDs on the logicboard. nothing to see there too. the only thing i noticed is, when i connect the power supply i hear an short noise coming from the PSU, i think and one (i think the first) LED flashes one time. also tried to push the internal power button, without success. noticed NO exploded or damaged capacitors on PSU and Logicboard (but i think thas more a problem of older G5).

View 6 Replies View RelatedI 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?
View 6 Replies View RelatedMy 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.
View 7 Replies View RelatedI've recently been having problems with my iMac G5 iSight after downloading iTunes 9. After a series of freeze-ups, i noticed a visual anomaly appear on my screen. Little hash-marks all over the display were present, and playing DVDs or iTunes visualizer would result in a checkerboard pattern. After doing some research, I found out this was a logic board problem, and it was not uncommon for iMac G5s. However, I kept using my computer for a few more months when it then started freezing two minutes after boot up. I figured it was time to open up the computer and take a look. But after spending the 3.5 hours opening the machine, removing all of the cables and screws, I couldn't find any visible damage on the board. No swollen capacitors like everyone was complaining about. The only strange thing I saw was some discoloration on a few circuits near the USB and Firewire outlets.
I've decided to replace the logic board myself for around $370, and I was wondering about a few things.
1. Would the new logic board come with a processor, or would I need to pry it off of my old one, and re-attach it?
2. Would I need to go through a lot of re-programing and software issues if I replaced my logic board, or would it just start running right off the bat after replacing it?
3. Is this operation worth it? Because I have come to like my iMac after 5 years of use, and I would like to know if fixing it would give me a decent amount of usage before I would simply need to replace it
At work, we have a 17" G5 iMac from back before the iSight was put in. We're an Apple shop, so we have the new iMac actually on the floor for people to try out. The old G5 this thread is addressing is up on a shelf, but we want to turn it on as a display model. We plug a temporary mouse and keyboard into it, but the machine never gets past the white Apple screen with the "I'm thinking" animation. After a minute or two, the fan turns on full blast, but the white screen remains without any signs of moving on. What is our problem?
View 6 Replies View RelatedI've got a 20" 2.1GHz iMac G5 iSight on my bench that doesn't power up.
I've tracked down the issue to a grenaded IC on the logic board.
The IC is an 8 pin SOIC chip, to the right of the power connector, just above the ALS connector. It is labeled UE300.
If you know what this guy is, can send me a good picture of one, or can provide me with the numbers from the IC, I can get this mac back to life.
Brother in laws imac g4 laptop does not start up. Is there a way to key command the computer to start up as a hard drive so we can save the data on his desk top?
He of course did not save the disks that came with his computer.
I have a PowerPC Imac. I have OS 10.4.11 installed on it. Today I started it up and it was working fine, however it froze while trying to load Photoshop. I had to force shut down and when I tried to reboot, I got a flashing folder and question mark. I have tried running Disk Utility, but it gets stuck at the Gathering Disk Information stage. I have tried resetting the PRAM (I think that's what it's called). It won't let me start up in safe mode or single-use mode. When I try to specify a startup disk, my hard drive is not listed.
What do I do? Is there any way to salvage this? My biggest concern are my pictures of my family that I unfortunately have not backed up.
So, I had read a few posts from various sites about how a problematic iSight (one that didn't show up in system profiler) could be possibly caused by a loose cable. The guides reported finding a loose connection in the iSight cable behind the bezel. They reported opening up their MBs and successfully getting behind there for the fix.
I thought I'd be okay opening up my 15" MBP to see if my iSight dilemma could be cured in the same way. I used this guide:
to get to the cable. I did skip a number of steps immediately following the detachment of the bezel; going directly to the upper iSight area simply disconnecting and then reconnecting the cable. This seems OK because the guide is for replacing the entire cable itself; whereas I just wanted to check the top connection.
A couple of nights ago I set my iMac G3 (Blueberry) to stop automatic login at start up and put it to sleep. I did this because I didn't want my kids on the web in the middle of the night while I was sleeping. When morning comes, the computer is off. I try to start it but it won't turn over. When I push the on button, the button flashes on for a split second and I hear the crackle of static as if the computer is starting, but nothing happens after that. I tried plugging and unplugging the computer, but nothing helps.
It's like a car that won't turn over.
I am currently experiencing problems booting up my imac 17-inch, 1.6GHz (2004 model I think). When I hit the power button the machine starts but the screen rmains black and after about 3 mins of this, the fan goes into overdrive! The only way I can turn the computer on at the moment is to remove the casing and use the on switch located inside the the machine, although this is no guarantee it will work, sometimes it does but the majority of times it will be the same black screen as before. All I am waiting to hear is the part in the top corner (hard drive~?) to click into gear and then it's fine, and the machine seems to work perfectly. But this is not a solution and I fear it is only a matter of time before the machine just explodes altogether
View 5 Replies View RelatedMy Mum has just turned on our family computer- an iMac G5, 1.9ghz 17" (first model with built in iSight).
It gets to the grey screen with the apple, with the loading icon below it, then after about a minute the fans turn out pretty loudly, and it goes no further, just stays on the grey screen.
I have an out-of-warranty 2005 iMac G5 running OS X 10.5 in my bedroom. The screen is very unreliable to the point where it stayed off all the time or gave weird colors and I had to purchase an external monitor (via mini-VGA). I have installed (successfully) spanning tools to allow both extended desktop (2 dual monitors) and mirrored display (2 monitors showing same thing).
However, after hooking up the external display, the iMac's bright display lights up my bedroom. I want to turn OFF my built-in display (i.e. no backlight) and have my external monitor act as my main display --- avoids having two displays eating electricity. Is this possible? (using any Terminal commands?) I don't want the computer to sleep, just to turn off the main display (even manually removing wires will work, if I can find a how-to guide on this!)
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?
When i open photobooth, all i get is the camera logo with a line going thru it... When i open ichat, it says no camera is attached... There is no green light, in system profiler under USB TREE, the isight is not even recognized....

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.
View 1 Replies View RelatedAs 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 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.
View 3 Replies View RelatedBesides 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]

iMac, imac g5 isight
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".
View 6 Replies View RelatedAccording 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.

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?
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?
View 2 Replies View RelatedI 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.
