My iMac Screen on my left side darker than my right side but it have been having this issue with my screen brighten up and down by itself from day one. Purchase my iMac about 13 months ago
Info:

I tried to use some software to test the display. I found when the screen goes to completely dark with the backlight on, the bottom side of my screen is brighter than other parts.... have u guys met any problem like that, or is this some problem with my MBA?
Just noticed the left side of my screen has a dark curve. What to do.Â
View 6 Replies View RelatedWith all the recent chatter around the 5870 cards, especially the availability and compatibility issues with older than 2009 Mac Pro's, I'm wondering whether OS X is still a viable platform for a 3D graphics artist.....Having only really acquired those credentials a short while ago. The 2 things that are really important for 3d graphics are a decent GPU and as much CPU rendering power as you can get. The 08 Mac Pro had both of these things and was great value but since then things have changed. It's not just the cost of upgrading a system although that's pretty damn high at the moment. It's other stuff like the 5870 having 2 MDP's instead of 1 and an HDMI port, which is in my opinion far more useful. It's all the hassle and limited choices when it comes to upgrading the GPU when you can slot anything into a decent PC rig and just get on with it. It's being able to build a decent core i7 system that can render away and chug out frames without costing as much or more than a decent car. And it's about forced obsolescence....Systems that are only 2 or 3 years old being left out of the loop and the sense that Apple took your extra money in exchange for upgrade potential, and then welshed on the deal.
Conversely, I love the OS X environment. It's stable, keeps out of the way, it's great for video and general digital life management. I don't need to be reminded of the pro's and I am in general an advocate of Macs. If I didn't do 3D graphics, I'd buy an iMac and be very happy but that just doesn't cut it in the 3D world. So I'm coming to the conclusion that my next big system purchase in a year or so is going to be a PC again. I envisage working on that during the day and having my Macbook open beside it for email and iTunes etc (ie, all the fun nice stuff) and then when the working day is done, firing up the MP or plugging in the MBP to the big screen for "everything else" like music, video etc....
my screen is just randomly going dark. its not shuting down - just seems to go to sleep but nothing I do wakes it short of turning the power button off then on. When I do that it quickly comes on again and seems to work fine. Seems to be happening with more and more frequency and is not particular to any software. I've read the boards here - I'm not a gamer ( no games on this computer) I'm a photographer with lots of files and I use photoshop alot. Yesterday I was on you tube and my screen went dark again but the video was still playing - I could still hear it. In fact, I could hit my mouse to stop and start the video but I couldn't see anything.

My son's imac screen went dark after a power interruption (someone turning the computer off by pulling cord out of electric socket) and I can't get it to go back on. I've already tried depressing the "command, alt,p and r" keys to get a restart, and while it did restart, still no picture on the screen. Occasionally you can see white staticy lines, but mostly it is just dark. I've seen the suggestions to update software and back up data but that isn't possible as far as I can tell because I can't see anything on the screen - it is totally dark!

My IMac screen keeps changing brightness as I use it, currently the LHS of the screen is not as bright as the right. Â
Does this sound like an adjustment or a fault? The sytem is about 6 months old from new.

Switched the machine on today to notice that the left side of the screen is darker than the right. I have put the brightness on full to confirm this. Is it possible the LED backlight is failing?

My 27" iMac, from the centre to the left side of the screen has a light grey shade whilst the right is normal, at times the screen flickers to normal then go's back to the light grey shade.

While online at a web site, filling in important forms, the screen suddenly fades to one side and disappears, and I cannot get it back, forcing me to start all over again. How can I stop this from happening?

I have a problem with my MacBook screen. Everytime I try to turn on the MacBook, the blue screen appears for a second and then everything gets dark (but I can see that the computer turned on normally, it's just the screen that gets almost black, without light). Sometimes only the right side of the screen is blue and then gets dark just like the left one. I was looking for the problem and I perceived that the left side seems to be loose and I can't fix it. What should I do?
View 2 Replies View RelatedI have a late 2006 Macbook, and my dad has an early 2009 Macbook. I was comparing the two today and noticed that there was a significant difference between their LCDs. My dad's Macbook has a lighter, more normal display. While mine has a yellow tint to it and is darker. Both computers were on the same display profiles and both had the same brightness set.
Is this just how LCDs are as they age? Or is mine really not supposed to have that yellow tint? The new Macbook is on the right in the pic.
I can barely see digital pictures and the likes. But websites and such i can see fine so long as the colors are light and looking on this site... [URL]
the first image i absolutely cannot see, it is 100% pitch black.. the other bellow it shows up just fine. But the two left/lowest squares on the color table on the very bottom the page both appear the same shade of pitch black.
I can see light but not dark. I tried callibrating and adjusting brightness and contrast.
I'm wondering how uniform the backlighting is on everyone's mid-2010 MBPs. The screen on mine is sort of a gradient, with the screen becoming progressively brighter towards the left side. There are also what appear to be columns where the screen is slightly darker than the surrounding area. This makes it annoying to read in low-light conditions because the left side of the screen will be at a comfortable level when the right side is slightly too dim, or the other extreme. I absolutely cannot stand dead/hot pixels though which makes me hesitant to have the screen replaced. I just bought the notebook a week ago but I don't want it replaced, as I installed a Moshi PalmGuard before I noticed the screen issues. I also installed an InvisibleShield but I can have that replaced at no cost.

It also has some "splotches" a patch or two of discoloring.
My iMac has these dark spots on the screen and I wanted to confirm that it is a hardware issue before I make an appointment with an Apple genius. I thought it was dirt, but cleaning it didn't do anything.

Today the screen just goes black.. when i turn the backlight up and down i can see some difference but no picture on screen.
The mac book is still on and music playing.
I bought an Imac 27'' like 6 months ago, but my screen seems to have some dark spots in the corner, when I put any white image, on that spots it shows like the screen were dusty but is not, at the same time in the middle screen when if Iput some black image some pixels show lighter than the others.

Late Model 2010 Macbook pro, opening screen from closed position allows the screen to turn on as normal, but two seconds later, goes to complete black. Temporary fix includes hitting F1 to lower brightenss (if the screen was at full brightness) or F1 or F2 (if screen was not at full brightness) changing this brightness level brings back screen to full brightness -1. this problem seems to be pretty prevelent and related to the nvidia card ro something simialr. are there any known fixes? will apple acknowlege this. this just started happening to me a week or so ago but i've seen articles are far back as early 2011 with the same symptoms.

My MacBook has suddenly gone dark. It charges fine and the battery lights show there's charge. The screen is very dark when powered up? When I turn the brightness down fully, then go to turn it up the screen lights up for a second then goes again?
View 6 Replies View RelatedMy MacBook Pro's screen has been going black recently, sometimes is pops back up and sometimes I have to shut down and reboot. But while the screen is dark the computer seems to be functioning (music still playing, sounds from touching keys randomly in the dark) I recently upgraded to Yosemite - coincidence or is my 6-year old Macbook just getting on in years?

My MacBook is from 2007, so it is old and has its problems.When I turned it on one day, it was all normal, and randomly the screen got so dark, it looked like the computer had shut down on me. I knew it was still turned on though because the little light was indicating that it was on and it was still making the cd drive/booting up sounds.Â
After a while, I noticed that the screen just went very very dim, because I could still slightly see the webpage I was on. Turning up the brightness of the screen did nothing, same with restarting the computer.
Sometimes the screen would come back to the normal brightness, until I would go to do something on the internet and it would go very dark again. It's so unpredictable, I don't even want to deal with it anymore.Â
I just bought the latest and greatest 15 inch Macbook Pro with Retina Display in mid-2014. Every once in awhile, my screen will go dark. When I hit the touch pad, the cursor will show up and will move, on a completely black background. At that point I panic and start depressing the touch pad, when that doesn't work, I try depressing the on/off key; which does not respond at first, but finally the screen returns to normal.? NOTE: My operating system is OSX 10.9.4.

The new Macbook pro 17" seems to have a very dark display. I was in two Apple stores in, one in NYC and the other in Whiteplains and both stores had the new machines displayed. The screens were substantially darker than the 15.4" LED version. The preferences did not seem to help because the machines did not provide a selection between power save and high performance. Does anybody know anything about this, or should I just assume mine will be delivered with a dark screen? The screens were glossy in both stores, NOT anti-glare.
View 11 Replies View RelatedI got a cheap 1.42ghz 512mb RAM, 14" screen G4 ibook because it had a broken hinge. I tore apart the laptop and replaced the hinge (screen frame) and put it back together. The screen wouldn't work. I opened it back up and found that the video connector was lose, so I connected it and put it back together. BAM!! Everything worked... everything except the sleep feature when the lid is closed. So I opened it back up, took the magnet from the old frame and put it on the new frame (which was missing its magnet).
When I turned it back on the screen was blank/dark. It showed all the signs of classic inverter board burnout (dark screen, can be seen with flashlight from behind, can be seen on external monitor), so I ordered an inverter board and when it arrived, I swapped it out. Still nothing. The next idea would be the backlight, but that doesn't make sense... I'm trying to figure out what might have happened to make the inverter/backlight go from working fine to not working when all I did was removed the screen back case, screw on the magnet and close it up. I have done a bunch of digging around under the hood and am wondering if anyone knows of a possible ground wire, other connection, easily broken wire, or other issue that might have happened. I'm thinking that it might be one of the power wires that goes into the inverter. It might have broken inside the shield, or maybe I was sold another bad inverter board.
So:
Assumption 1: one or both inverter boards are good.
Are there any connections other than the inverter data/power cable from the mobo and the cable from the inverter to the backlight?
Does anything else (backlight, etc) have to be grounded? Where are these groundings?
Would anything else give the same symptoms except the inverter?
How can I test the backlight? I heard that there are two lights in these machines, so if it was one of the florescent lights, only 1/2 the screen would be dark.
Assumption 2: Neither board is good and that is the problem.
How can I test the inverter board (short of an osilascope) to see if it's working?
Is this a good assumption?
I'm about stumped right now and haven't found any direct help on forums. I'm hoping someone in the Mac community has run into this or has an idea about what could be going on. I'm really hoping that I missed something like replacing a screw that is also a ground or something along those lines.
dread going to work and use pc all day. anyway the only issue i have is every so often i will be working away and my whole screen goes blank for a second,,freezes. I have to tap the mouse to get it to come back,
