The only way to test is to use a known working power supply or known working cinema display with the parts you already have.

After a couple of electrical power outages my Cinema 20" Apple monitor doesn't work. The power light (lower right) goes through cycles of off, dim, bright, etc. sort of as if it's flashing a Morse...


There are three "morse code" flashes that an Apple Cinema display can produce that are diagnostic:
Three short flashes (morse "s") means incompatible video format. Try resetting the parameter RAM when restarting to go to the default

Short-long-short (morse "r") means "wrong power adapter." I've seen some monitors that will not work with an adapter that others will and that give this signal. In some cases this can be fixed by insulating the power sensing pin on the display power cord.

Finally morse "u" (short-short-long) means a backlight problem.

Apple Cinema HD Display 30'' black screen, power light blinking


I don't know what might have happened, but a number of years ago I had an apple monitor and the power light on it started blinking, so I got in touch with apple and they told me that it's flashing an error code, so they told me what the blinking indicated and fixed it.

So I think the blinking of the power light on your monitor could be indicating an error code so I suggest you call apple and they will identify what the error is indicating.

Apple Cinema Display 23" LED short-long-short flash prob.


Hello, I had the "short long short" blinking led problem with my 23" ACD after a power outage which left my screen blank and my cheek wet with a tear for my baby. I read somewhere that a guy was getting a 1 volt reading on the middle pin of his damaged 90 watt power block. I figured maybe the display might work if I could somehow block the middle pin. So I cut a small strip of paper wide enough to block just the middle pin and long enough to cover both sides, folded it to look like a "W" from the side. I then carefully pressed it into the brick receptacle with a toothpick leaving just a little slack so it would not tear when I pushed in the small white plug. It was a bit of a tight fit but guess what. IT WORKED! I am now enjoying my beloved monitor anew and saved $$$ on replacement brick or repair. If you want to try it and you feel you’ve nothing to lose, make sure you cover just the middle pin (both sides) and you may have to try a couple of times. It worked for me. I hope you have good luck too. Regards, Moozler

edit December 2016. Still working after 7 years.

***CAVEAT AND WARNING***
Use this fix at your own risk.
A faulty voltage regulator is probably the cause of failure. Voltage regulators can start a fire if too much voltage is applied.

Bud Martin's post below describes the electronic component failure that causes this problem. Thank you Bud.

For the brave of heart, You can disassemble the monitor. After you get in to the inside of it, you'll see a circuit panel with 6 ballast coils on it. On my Cinema display, what happened was that the solder joints on some of those coils had cracked, causing intermittent connection. After hitting all the connections with a soldering iron to heal the cold solder joints and re-assembling it, it is working perfectly fine now.
