Question: Apple Cinema Display 23" - Blank Screen, "short-long-short" LED code
This sounds like something of an epidemic... My Apple Cinema 23" HD Display (bought Dec. 2007) hasn't been turning on after a power outage hit our area last week.
The Computer and Display were OFF when the outage occurred. Everything was plugged into a surge suppressor. Everything ELSE plugged in to the suppressor is fine (including my Mac CPU)... but not the monitor.
It’s not dead-dead…. It’s a blank screen but there IS a morse-code flash on the LED (short-long-short). According to Apple Support’s LED Translation, it SHOULD be something to do with the power adaptor. The adaptor IS correct… a 90 watt… but just in case I bought ANOTHER 90w adaptor brick. I plugged the monitor to the new brick. THE RESULT WAS THE SAME.
I’ve tried power cycling, I’ve tried plugging it into different outlets, I’ve tried connecting to other computers. The same LED result remains.
And, yes, of course, I’ve got no Apple Support, and from what I read in similar posts, outside-the-warranty repairs could hit around $400. I REFUSE!
For now I have a Samsung monitor from Costco. It’s not bad, but it’s not the Apple monitor with its awesome color-fidelity.
I've read some other posts with the same problem (LED blink code and all) elsewhere but haven't got a solid answer.
I wonder… has anyone else incurring this same problem (with the same LED flashing deal) tried to use a 150-WATT adaptor brick? I would try this myself, but I’m currently financially unable (and personally unwilling) to throw more cash at this problem unless I know it’ll fix it.
