Intel Mac :: 27 Inch Screen Won't Turn On?

May 11, 2012

my imac is about 3months out of the box and a few days ago i went to turn it on and....nothing.  i could hear the start-up chime and the mac clicking and making "doing" noises, also i could clearly hear the volume toggle up and down.  That said, the screen remained, well, dead and just black.So, the first thing on my agenda for the weekend was to take my imac into the shop.  As i was organising the equipment, i tried one more time to turn it on.It worked.For me, that's a bad thing as my mac may do this again.  It was out of action for 3 days now it's back.  So now i am on here.

OS X Mavericks :: IMac Start Up With Apple Logo And Sound But Then Screen Turn Off

Jun 2, 2014

This situation began when I put my Imac on sleep. After, the screen turned on in black whit the cursor but I couldn't do anything.

Then to rebooted the machine, the apple logo and sound  began fine but the screen turned off, so moving the mouse the screen turned on in black with cursor. 

I'd tried many ways, resetting the PRAM, SMC, repairing the disk and permission, analyzing hardware, repairing fsck files.

Suddenly, when I entered in Verbose mode, mi imac brought into user choose screen and worked fine, but when I shut down and tried to start my mac in the next day, it didn´t work again.

IMac :: New 21.5 Inch ... Getting Random Black Screen

Sep 24, 2010

The screen randomly turns black without any major reasons. It doesn't seem to be a sleep mode/screen saver thing as the music continues to play on. I can adjust the volume or pause the music with the keyboard but the screen just won't turn back on. I have to shut it down using the power button and it happened several time the last couple days. Anyone else experience the same thing and got a solution?

PowerPC :: Screen Repair - 20 Inch Imac G5?

May 21, 2009

My lovely cat recently decided to walk around my desk while I was at work and knocked over my Imac, causing a large crack in the glass and the screen. I'm not technically capable enough to do the install of the screen/glass myself, but I was wondering what I should expect a repair from an Apple certified technician to run.

IMac :: 27-inch - Dust Under The Screen - How To Clean

Jul 17, 2010

A few months ago, i noticed what looked like a streak across the screen, but it wasnt on the outside, it was on the under side of the glass. Now, the streak is very visible esp in natural lighting. Its not noticable at night, because the screen light shines through it making it invisible.

It looks like dust? But im not 100% sure, but it has a directional pattern which leads me to believe its being causes by the inner fans of the system, and that there are some gaps where the air flow is constant. Also, the streak is in the upper left hand corner mostly (no where on the bottom poritions). Im assuming that the place holder at the top-backside of the iMac, for the exhaust fans to expell the heat from within, is what is causing this air flow.

IMac (Intel) :: 27 Inch - Screen Randomly Goes Off?

Jun 2, 2014

I have a 27" iMac. Just recently, the screen has begun to randomly shut off. I then have to squeeze the power button, followed by a click of the mouse. This will bring me back to my password screen. Sometimes, that would be it, other times, it will do it repeatedly, for no reason, and then settle down. 

Just for those of you who are bound to ask me about my Energy saving settings: Computer to sleep – Never. Display to sleep – 15 min. 

It seems to me that this could be a hardware issue, but just incase any of you have had any experience of something similar, I thought I would ask.

IMac :: Have An Inch Wide White Stripe On My Screen?

Jun 11, 2008

I have an inch wide white stripe that runs from the top to the bottom of my screen. This is on an Imac. The cursor disappears when going through it but pops out on the other side. It doesn't move but I can drag my window back and forth to view the part the stripe covers.

Any ideas or should I locate a local mac repair person?

IMac :: How To Turn Off IMac Screen But Leave Secondary Screen On?

Dec 21, 2009

I'm sure this should be simple but I can't figure it out.

I have my iMac connected to my TV and am using Plex to watch stuff on the TV.

What I'd like to do is turn my imac screen off without turning off the second monitor output (i.e. tv) as the imac screen is a bit bright/distracting (even on lowest brightness) when watching in the dark.

IMac :: The New 27-inch IMac Uses Up To 365W Versus 280W For The Old 24-inch!

Oct 20, 2009

The new 27-inch iMac uses up to 365W vs 280W for the old 24-inch! (going by Apple's published max. power consumption numbers. I doubt they would lie because it isn't exactly favourable for them to put in falsely high numbers in an environmental report).

That means there's some extra beef behind the extra components. Perhaps the ATI 4670 is a bit overclocked and the 4850 runs a bit faster than the old iMacs? Admittedly that 2.8 GHz i7 is going to suck a fair bit of power - the recent 2.8 GHz i7 860 model runs at a 95W TDP, however, the quad core iMac isn't available until November. So it won't be using the i7 860, and my guess it is using another custom processor, something a bit more power efficient, somewhere in between the 55W TDP of the old iMacs and the 95W TDP of the i7 860.

The difference between the power consumption of the two computers is 85W. The old iMac had a 24-watt digital amplifier, this new one has two 17-watt amplifiers. That brings the delta down to 75W. Say the iMac's i7 processor has an 80W TDP. That now brings the delta down to 50W. The new display likely wouldn't increase power consumption because of the LED backlight.

I'm not sure if I'm missing much (OK, two extra RAM chips may use another few watts), but there is still a fairly massive 50W unaccounted for.

Just a bit of fat to chew on

IMac :: Base I3 27 Inch Or A Refurbished I5 Quad Core 27 Inch

Jul 29, 2010

Hello everyone, I'm currently looking to buy a 27 inch imac and can't decide whether to get a base i3 27 inch or a refurbished i5 quad core 27 inch. With the i3 I can get the student discount and qualify for the ipod, but the i5 is 23% off right now. Which should I get? Also is there a benefit of getting a 5 series graphics card over a 4 series graphics card?

I would like to keep the MacOS folder from opening each time I re-boot the computer..How do I prevent a window opening with MacOS files showing when starting the computer?

I have cleared the "History" even though it does not show there.  I notice in "Finder" under "Go" there is a "Recent Folders" and it shows there.  I have Cleared it from there and restart the computer and "MacOS" folder still opens in the center of the screen or where ever I moved it to before closing it.  I have tried a Safe Boot and it still shows when re-starting..I would like to keep the MacOS folder from opening each time I re-boot the computer...

IMac :: How Do You Turn Off The Screen

Aug 29, 2010

I know how to dim the screen, and I'm using Shades to help with that, but I would like it turned completely off.

For example, if I'm burning a DVD overnight, I want the screen to be completely shut off, instead of lighting up the room like it's the middle of the day.

MacBook :: Error Message During Ichat - Won't Turn On?

Jul 18, 2009

On Tuesday I was using my computer for several hours when a "Panic" error message appeared. I could not move the mouse or get the computer to respond so I restarted. At this point my computer would not turn back on, so I removed the battery pack and replaced it, it still did not turn on. I hadn't been doing anything except sitting in my room talking on ichat and browsing on safari, so naturally I was really confused how such a cataclysmic event occur that would cause my computer to not even restart. At this point I got on my PC downstairs and made an appointment with my local Apple store.

When I got to the store they told me at the genius bar that it had been a kernel error, and asked me a few general questions about its typical performance and whether anything had been out of the ordinary recently, it had not. Next the "genius" I was working with asked if I had been having battery issues, and I did not think I had been until he asked if it was typical for my computer to be "calculating remaining battery". My computer had been giving me that message periodically since I bought it, but I thought that was typical. That is exactly what I told him and then he said he thought it could be my Logic Board, but as long as I had not spilled anything on it the AppleCare would cover any repairs...........................

IMac :: 21.5 Inch Versus 27 Inch

Nov 18, 2010

I got a MacBook Pro back in April, my first Mac.

I love it so much. I'm really into video editing and HD video, but the problem is that my MBP is running out of harddrive space, and I'm longing for a bigger display and a better processor. (I have the 13" C2D). I'm going to pick up an iMac this Spring. But I wanted to know if I should stick to the Core i3 21.5, or spend more and go for the 27 inch.

After having inserted a dvd borrowed from the library which my Imac had a really tough time reading, I turned off my Imac as usual. Since then when I turn my mac on the fan starts roaring and i don't get beyond the first white screen with the sort of clocked wheel just going round and round. I don't have a clue to what to do.

IMac :: 21.5" Screen Doesn't Turn On When Waking From Sleep?

May 8, 2010

I'm not entirely sure how long my iMac has been doing this, maybe two weeks? When I try to wake it from sleep, the screen does not turn on. At all. At first I thought this was because my mouse and keyboard might not be functioning correctly, naturally the only remedy was to turn the computer off with the power button and to restart it (which took an abnormally long time). Today I remote connected with Back to my Mac screen sharing and it did not turn on either. I know it was awake because when I pressed the brightness buttons on the keyboard, it responded on my MBA's view of the screen. Normally, Back to my Mac does turn the screen back on. Anyone else have the same problem? It doesn't seem to matter WHEN it goes to sleep either. I've tried resetting the PRAM already and no dice.
