Q: 24 inch LED cinema Display momentarily goes black
-
Feb 8, 2011 2:42 PMby Yk2kc7bAa,I also have the flicker / all-out fail on the 24" LED. I suspect that my USB headphones might have something to do with it, even when engaged via the laptop. Downgrading the headphones to the mini-jack on the laptop eliminates flicker altogether. No headphones at all and I still get the random 2-second flickering or total outage requiring power cycling the display and reconnecting all-in-one cabling.
Monitor is at work and is less than a year old. Have already had one logic board replacement from the Apple Store, that helped for about a month. I'd prefer to RMA this terrible inconvenience at this point. -

Took it into my friendly Apple store in Manchester UK, they tested it, could replicate the intermittent flickering black screen and replaced the entire LED panel inside the screen at a cost of over £400 on warranty, (even though 3 months out of warranty). All fixed now and very happy indeed.
I suggest that many of the proposed solutions on this forum including replacing leads etc are a waste of time - respectfully. -
Mar 31, 2011 12:30 PMby Thorsten Geissler,My 24 inch Apple LED cinema Display momentarily goes black even after 10.6.7 update. The display is connected to my new 15 inch MBP i7. Talked to "Genius" @ the Apple store in my town. No help, no solution provided. Any ideas? I am kinda frustrated with Apple to be honest. -
May 7, 2011 3:30 PMby Thorsten Geissler,I agree. Talked to AppleCare. Solved nothing. Ridiculous!! I about had it with Apple. It's annoying me and I am g etting really upset. I applied the latest patches and updated the firmware on 2011 MBP (13 inch). Nothing changed. LED cinema display still goes black momentarily. *****!

Nov 16, 2011 5:28 PMby Rmusictrax,My 24 inch LED cinema display which I use with my Macbook pro went black a few days ago for no apparent reason. I just came back from the Apple Store with the infamous 10% rebate card and a huge door stopper, or a huge usb hub..... whatever. I'm not impressed. Apple monitors are 3 times the price and who would think of taking an extended warranty on something like that, in all my years i've never had a monitor go black on me, ever, except this overpriced piece of made in china *****.
After being a hardcore Apple fan for years, my infatuation of the Apple brand has been deflated quite a bit tonight. I've come back to reality. Apple products are no better than any other and are NOT worth the asking price. Its all a figment of the imagination made possible by marketing.
My advice, buy a less expensive monitor from another company. At least if something goes wrong you won"t have overpaid for it. You can buy a 27" Samsung monitor which looks incrediblbly good for 1/3 of the price.
My 2 cents.

Dec 26, 2011 1:55 PMby harold_c,I finally encountered this problem with my 24" ACD today after 2 years of trouble free usage. I was using the MacBook Pro seperately and then came to plug the monitor back in and it started happening.
I briefly read about the RF interference and seperated the display port cable from the USB hard drive cable and it has gone away! No need to wrap the cable, just make sure it's not running along anything that carries power, like a USB HD.
HTH.

Jan 8, 2012 5:56 PMby AtomMan,Apple made a firmware updated available for the 24" Cinema Display in early October. I've had the same problem for a couple of years, but after the tech at the Genius Bar ran the update last week, the problem seems to have been resolved. It's an issue with the mini-display port and the cable for the monitor. Go to an Apple Store or call Apple Care (this update is not something that will show up automatically when you run software update).
