OS X :: IMac G5 17" ISight - Monitor Won't Turn On?
Jul 10, 2009
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?

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]

tonight I started having trouble with my intel iMac (running OSX 10.4.11). I'm having issues with two things (bolded for those skimming):
Out of seemingly nowhere, my iSight light turned on and now wont turn off. The only program I had open at the time was Firefox. When I try to open up PhotoBooth it says this:
There's nothing listed under USB High-Speed Bus in the system profiler either.
I've tried logging out of my user account, restarting, shutting down, unplugging and holding the back button for 5 seconds ...none of that worked. I tried resetting my Mac's PRAM and NVRAM. That didn't work either, and that's where a second problem appeared: when I try to shut my computer off, it freezes. I have to shut it off by holding the back button.
Is repairing the permissions and/or disk worth a shot? Or should I just take it straight into the Apple store? I hope it's not a hardware issue because I just recently had a new hard-drive installed after it broke down on December 15.

I am seriously considering the possibility of using the 27in iMac as an external monitor with my MBP when I am home and need the extra monitor space. That would also allow my family to use the iMac when I am away at work or out of town. Since my MBP has a Mini DisplayPort, it should be as easy as connecting the MDP from the laptop to the MDP on the back of the iMac and then connecting the USB for audio? However if the iMac is turned on, how can I use the monitor without the actual computer running at the same time?

i have a imac g5 and it is hooked up to an external monitor. the reason why i want to turn off the imac screen is because the lcd is cracked. i just want to use the other monitor as the main one.

i've looked far and wide for a way to turn the monitor off on my new imac 24", nvidia 8800, running xp and still havent found anything. does anyone know of a way to turn it off? i've tried to set the "turn monitor off" setting to 1 min under power management and it gets ignored. also, i've even written an app to try and turn the screen off based on this: [URL:...] and it is also completely ignored.

**Intel Imac 24 in. 2.4GHZ Core 2 Duo (NOT G5...my bad)
I know the "Using imac as external monitor" topic has been adressed in previous posts and it apparently can't be done. But this is slightly different.
I have this Imac G5 24" that is currently out of order. (won't detect hard drives when powered on 90% of the time and when it does i am experiencing ridiculous lag and random shutdowns...not to mention crazy overheating)
I sent it to tech support and after changing the hard drive, power supply etc.. and still not seeing any improvement i just stopped sinking money in repairs and got a new imac.
So now i just have this useless imac laying around and i figured i might as well try and recycle it into a secondary monitor.. I don't mind hacking it open since i have nothing to lose. I was just wondering if it could be done and if so would it be very complicated? I would rather pay a few hundred dollars in wires and IT than buy a cheap external monitor since its already a decent quality monitor and it matches the new imac

I'm only posting this to continue my procrastination of starting homework which is due tomorrow. Ok, so recently I've been asking on these forums how to access my Macbook using my iPod Touch. Being able to fully access my Macbook when I'm 20 miles away at my University is a huge benefit when I realize I forgot an important essay or homework. I discovered I just have to open up port 5900, etc etc, to get into my Macbook from anywhere. It was too much trouble and now I just use [URL] which works as well, though don't think as fast. Well, this works wonders since I've already emailed myself 2 important Keynotes i've create and accessed them from my college and presented them without even having my computer on me.
Well, recently when I get home at night some times it smells strongly of marijuana. Odd since I don't smoke it but my cousin does. He has access to my place and I say he can head over, even if i'm not home and chill, but under any circumstances no smoking. Well, I wanted to use the iSight cam w/ Photo Booth while I'm at the college to see if he indeed was getting high in my living room but before I tested it, I need to get rid of the green light on my Macbook: Getting Rid of The Green Light. Ok, so we're not really turning off the green light here. I looked for hours on how to do this and instead ran into a lot of advice, especially on MacRumors forums, to just white out or tape a small white square over the dot when the green light comes through.
Don't attempt the white out. It'll just go through. As for the white small square...it's completely obvious so don't try that either. Instead, do this:
1. Get a thin card, like a debit card and gently remove the white frame from your macbook. Attached to the back of the frame will be a bunch of these little gray rectangles that hold that frame to the outer part of the macbook. You'll have to take these off gently from the frame and pop them back onto their corresponding places within the Macbook. Easy enough.
2. Then what you do it get a sheet of white paper, cut a super small piece and fold it many times over. Not too thick or the frame won't click back in that area normally.
3. Place it snuggly where the green light turns on and even suggest getting a piece of tape just as small to hold it in place.
4. Turn on Photo booth just to test out if the light goes through. It may but really test it by placing the frame over it, and then seeing if the light goes through.
5. If it doesn't great. Place the frame back on and you're set!

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!)

I have a Mac Pro 8 core that is almost 2 years old. Still running Leopard and 10.6 I believe.
This morning all worked great, and after a lunch break the 30" Apple monitor won't turn on. The power lights on the monitor. We substituted an older 22" we have and that won't work as well.
We tried both video inputs on the back on the computer and still nothing.
When we turn on the computer we hear the Apple signature sound and even though there is no visual on the monitor, this computer has a QuicKey keystroke to shut down the computer and this works.
Is this a graphics card failure?

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?

Is there a simple app, key combo, or a way I can use AppleScript, to turn off my monitor manually (resume on mouse move)? I need something like this for the automatic input switcher on my monitor to work.

Earlier this summer, my iMac suffered a crashed Logic Board. Thankfully AppleCare took care of the $900 it would have cost to replace it.
Earlier today I put my MacBook Pro to sleep by closing the lid. About 2 hours later I went to open the lid and the monitor never turned on. The white light is on in the front. I restarted it and the light remained on and the monitor did not turn on. I unplugged all devices and restarted and still no luck. The Number Lock key lights up and the sound works fine - but no display.
Could this be another failed Logic Board or a failed chip set from here:[URL]
Are there some other types of methods I should try (PRAM Reset, etc.) If I have to bring it in, thankfully AppleCare covers this Mac for another year. What horrible luck - college just started.

2012 Mac mini with a Thunderbolt display, recently updated to 10.9.3. Normally, it's set to never sleep, but to have the display turn off after 15 minutes with no screen saver. Since the 10.9.3 update, it won't turn off at all. I've tried changing the settings back and forth with no results. I've also gone into Library->Preferences->SystemConfiguration and deleted the PowerManagement.plist file.
I can turn the power off with control-shift-eject, but I'd rather it happen automatically. Is there something else new that came along with 10.9.3 that is preventing monitor shutdown?
Info:
Mac mini (Late 2012), OS X Mavericks (10.9.3)

I'm trying to rig up a system for work that will allow me to remotely monitor an industrial job site for a few hours each day and control some equipment. I've got the ability setup to remotely control the equipment, but I need a dedicated camera on an engine tach and pump presser gauge. My original plan for a remote camera is not working and time is running short, so I thought I could end up using the new MB I got recently with the integrated webcam, and VNC into the computer. I tried it out today and it seemed to work well except for two things, both related to the display being on.
1) There is no power available so maximizing battery life is a must
2) I was getting a bit of a glare off the gauges from the screen that made viewing a bit difficult.
I think both would be solved if I could run the MB with the screen off, but I don't know if this is possible.

I'm currently working out a plan to use my old Macbook as an AppleTV equivalent- I've found out about atv4mac and it sounds ideal. However, the laptop will spend the whole time running with the lid closed, is there any way to totally turn off the monitor? I can turn the brightness down all the way, but it's still on, seems like a bit of a waste!

I know that the web have a lot of tips similar to this that i will ask, but i couldn't find no one exactly with what i want
I bought a new monitor, and mini-dvi adapter, an external keyboard and mouse to plug on my macbook
I would like to know how to turn off the macbook display without having to close it. I want to know that because if i don't close the macbook, both displays are on. If i close the macbook, the computer goes to sleep and then i press some keys on keyboard and the mac wake. In that point, if i open my macbook the display is turned off like i want. But i don't want to have to close the macbook all the time, and i don't want to leave the macbook closed because closed the temperature goes high.

My goal is very simple for the time being.... run my 2 LCD monitors together so I can have double the desktop space. I plugged everything in properly and it seemed to work right away at my pleasure. However, then I quickly started getting real pissed off.. If you guys have ever looked into the "displays" option when you have a mac hooked up to any other kind of external monitor, there is a "mirror displays" option. When I have these 2 monitors running default mirrored, and go into "Displays" there is no option for unchecking the mirroring box. In fact, there isn't even the "Arrangement" tab. Just "Display" and "Color".

I was surprised one day to find an inch of white line running from top to bottom on my screen. Then after a week it expanded to two inches white line, then suddenly it turned all black and I can't see two inches of my screen from the right edge. I was reading some forums and found out that I can use a dell monitor as a secondary monitor, but is it possible to use the dell monitor as the primary monitor in case the black line will spread throughout the entire iMac screen? so the iMac would serve as a stand alone processor like a regular desktop?

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.

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?
