cinema display recognized, but black with non-working power button

Michael,

I seem to be having the same exact problem as you. I use my older clear cinema 23' as my main monitor and my 17' as my secondary. Anyways i had the backlight inverter switched and just like yours it got rid of the blink but ends up coming on for a split second at boot and then goes black. and when i mess with the mirror setting or screen res it just glitches on for a split second and then back to black. Everything on the monitor seems to work fine just no video.

I tried what you said about messing with the screen res and mirroring but to no avail. Have you found anything that fixes this since your last post?

thanks

Zach

Had the same problem. I disconnected all USB/Firewall cables, reconnected the cables on the brick, it didn't help, but with disconnecting ALL cables (brick too), wait a couple of minutes (15) and the monitor came back. Let see, that this stays... =)

I recently bought six 23" displays two for each of the Intel towers I bought at the same time. Of the three computers two of them blink three long blinks and a pause, on one of their monitors, the third one does not. Each of them are setup the same way, in the settings.

BUT the two with the blinking issues were macs that were transfered to the new OS from old G5 towers. The one that does not blink was a new install with no transfer.

I also just noticed that on the macs that are blinking, there is no options tab in the display preferences on the screen that is blinking. On the mac with no issues there is an option tab on both screen's display preferences tab. It MUST be an issue from transferring the old mac's data to the new operating system.

I got my ACD Fedex to me on my birthday.

Today I plug to my new MacBook Pro 2,2 and it went black.
I replug to my MacBook 2.0 (all same settings) and the screen is on Instantly.

So it's not a Brick problem. I'm definite about this. If it's brick problem (which is definitely use on both MB and MBP) how come it's turned on by one but not by another?

However I'm taking mine to Apple shop ASAP (tomorrow morning) as my birthday in 3 days which mean Apple Care died in 3 days.

If anyone have another Idea it's a great time to post.

Sincerely yours,

i have a year old cinema with the same problems! it's recognized, I can pan the mouse across it but the monitor is black and the button is off!

it magically just started working today. after a week. weird.

well it only worked twice for me before going back to its same active but black screen ways....

this is not - i repeat not a hardware problem - it s the last upgrade problem -the quicktime and itunes

Has anyone tried a clean reinstall or a reinstall would love to know if that would zero the upgrades

worked last night pulling the power today Nada zip
had the display a year no problumes

the same here , only my 23" works fine with mac osx but is black when i boot in vista

still no solution

I reseting the PMU (intel only has the SMC) and followed detalspark's last post. Still have the problem.

Is it possible that somehow the software update did something to the power adapter boxes and maybe thats why those people who have gotten new ones have no more troubles?

I will be asking about this on Friday when I go to the Apple Store. I guess it is possible. There could be a chip in the power supply that requires a firmware update.

Good question.

i figured my problem out it was the power supply "brick" that connects the display to the G5. i had to buy a new one which costs 66$ when you trade your old one in. Otherwise it is around ninety$
