    Way to go with the backlight repair! By the way, I was under the impression that 2003 era Apple 20" Cinema Displays were made by LG-Philips. See the Anandtech article...

    Same issue with 23 inch display. Just returned from Apple Store to hear how much they would charge ($425) for repair which is just not going to happen. Ought Apple
    to have a response to this issue given number of posts? What is the problem inside these monitors?

    Same problem with Apple Cinema Display 23". Bought a new 150 W power adapter and the display works fine. Thanks for the tip!

    This same issue just popped up for me after the holiday break. I had a 150W adapter on hand, but in my case, the monitor keeps flashing the short long short code. Frustrating, as this monitor was unplugged from all power over the break, and has lived its life plugged into a pure sine wave UPS!

    Same issue here too with my 20" display, only 3 years old, tried using a new 65w power adapter, no joy, I'm waiting for a 150w power adapter to arrive bought from ebay, hope this works even though it may only be a quick fix.

    After reading all of the posts about this same problem it seems like Apple might look at this as a problem warrantying a recall. I am having the exact same issue with one of my two 23" Cinema Displays. They are both connected to a UPS in a controlled professional video post-production facility. After coming back from the holidays, I hit the power button on the Mac Pro and only one monitor came on. . . short. . . long . . . short flashes on the other. I too tried the power adapter from the other monitor, no luck. Tried connecting to my MacBook Pro, no luck. These monitors are 16 months old, and no, I did not opt for Applecare.

    I will always own Apple machines, but it looks like I am looking much closer at Dell U2410 monitors! Three year warranty with "No-Dead Pixel" guarantee. I must also point out that they are 40% less expensive and use a newer version of the IPS panel. Not nearly as sexy looking. . . but they have a great personality!

    hey all,

    this same problem just happened to me this weekend too. made a stop to the genius bar, and they tried out the 150w adapter, which worked. but they suspect this is just a short term fix. does anyone who has been using the 150w have any longer term experience? is the $100 investment a good one?

    also, what are proper channels with some real efficacy to bring this up to powers that be at apple? what a crock for pretty pricey display, if there's no support for this known problem... much appreciated everyone!

    I took my faulty 23" Cinema Display to the local Genius Bar last night, and after reading everyone's posts, I asked the tech to connect a 150W power adapter. . . and it worked. He said that he had never seen this issue, but after I told him how many people were having the same issue, he looked to see if there was any sort of recall. Unfortunately not. For what is to be considered a "Premium Panel" monitor, there is not a "Premium Guarantee" of workmanship for the "Premium Price" we are paying. Now the question is, do I sink $150 into a temporary fix, or do I go ahead and buy a pair of Dell 24" U2410 monitors with a 3 year warranty and dead pixel guarantee.

    Just finished the phone call with Apple. They're going to repair it free. No Charge.... Gratis.....
    So just call tech support and get to customer relations. They gave me a new case number and I'm dropping it off at the Apple store. Let me know how it goes for everyone.
    BTW.... be very nice on the phone.

    For those of you who don't want to spend +$100 on a 150W adapter may want to give this a try:

    It turns out the middle pin in the power connector is a ground. When it read an incorrect voltage it makes the displays inverter turn off to protect the unit. One way to circumvent this is to cover the middle pin in the cord going from the monitor to the power brick. I used a piece of paper in the shape of a "W" covering just the middle pin. I double folded a piece of paper and folded it over the plug and down into the connector and then gently pushed the plug into the power brick. Once i did this the monitor popped on and all was good in the world...

    Was your Cinema Display out of warranty? That is my only concern is that mine is out of warranty. Should I do ahead and call? Thanks.

    Yes, mine is way out of warranty. My complaint to them was, I spent almost $1000 on a premium display and it only lasts a little over 2 years. WOW!!! They are fixing it free of charge. Call them.

    So I am trying to contact Apple support, and it is asking me to pay for a Pay Per Incident for $49 in order to get in touch with support. Did you have to do this in order to call? Any suggestions? Thanks.

    No. Just call tech support, the number is on the Apple website. Don't pay anything.
