Question about Apple Cinema HD Display30" Flat Panel Monitor

1 Answer

30" apple monitor...i have to start and restart computer several times before the monitor will come on. It is like there is no power to monitor and then there is power

I have changed outlets and still no power. Then after several different outlets, the monitor will come on. If I turn computer off after the monitor has come on, and change monitor to an outlet that I had tried before that did not work...the monitor works.

SOURCE: 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.

This issue is can be caused by loose cable connections or a loose DVI graphics card in the computer. Check cable connections and verify there are no bent pins.

Ensure that the DVI graphics card is securely connected in the computer.

You can also try this procedure with your Mac:

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} -PRAM RESET -
Here are some steps you can try to resolve the issue:

• First, hold in your power button for approximately 10 seconds to do a hard shutdown, if you have not already turned your Mac off.

• Once your Mac is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)
This should help with the freezing issue:

• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

• Now, hold the keys down until the computer restarts and you hear the startup sound for the third time.

• Release the keys and allow the Mac to start up.

• Please update me to let me know if this works.



A PRAM is a good troubleshooting procedure for display issues.



If this does not work, this may be a genuine issue with the graphics card in your Mac, more so, than 2 monitor just burning out. You may need to take the Apple ADC 17" in for service, if the procedures above fails.

SOURCE: apple cinema display has interference

Check your DVI cable for breaks. If that's not the problem, then you'll need a new IP board. Not sure of the part number for this monitor, it's printed on the circuit board. It starts with 820-XXXX or 620-XXXX in some cases.

Black screen when turned onno display


There are several reasons that your Toshiba laptop screen may not come on, even if the laptop appears to be running, and several options you may try to get your screen back up and running without an expensive service call.


Common causes for a blank screen include a backlight that is turned off, a display toggled to an external monitor and improper shutdown errors.


To avoid blank screen errors after your current error is fixed, make sure to follow all instructions in your user's guide to care for your Toshiba computer.


Shine a flashlight directly at your screen and look for an image.

If you see one, this means the backlight on your laptop is off but the screen is still working. This backlight normally turns off only when your screen is closed.


Look for a small metal or plastic pin near one of the screen hinges.

The screen pushes this pin in when it is closed, so if the pin is stuck in the screen closed position, the backlight will remain off.


Tap the pin several times to release it.

You may need to use a small object, such as a pencil tip or straightened paper clip, to reach it on some models.


Monitor Toggle


Press and hold down the "Fn" key if you do not see an image when you use the flashlight.


Tap the "F5" key several times while the "Fn" key is pressed.

This will cycle your screen through the various options that toggle the display to an external monitor.


Attach an external monitor, restart the computer and try this method again if no image appears on the laptop screen.


Click "Start," "Control panel," "Hardware and sound," then "Device manager "using the external monitor if you get an image there but cannot toggle the image back to your LCD.


Select the "Monitor" option to expand your selection and select your LCD monitor from the device list.


Click the "Driver" tab and select "Update" to update the driver, as this error is likely caused by a software driver error.


Force Restart


Press and hold the power button until the computer shuts down completely.


Check the indicator lights at the edge of your laptop to see if the computer is truly off or if it has simply gone into hibernation mode.


If it is off, all lights will be off except the battery-related lights if you have a charger plugged in. In hibernation mode, the power light will blink slowly.


Press the power button to restart the computer again after leaving it off for 15 to 20 seconds. This may fix the problem.


If the blank screen returns or you get a flash of images and then a blank screen, move on to the next step.


Force Power Down


Unplug your laptop from the power source.


Remove the battery by pressing outward on the battery latch and pulling the battery unit completely out of the computer.


Press the power button several times to completely discharge the computer.


Replace the battery and plug the computer back in after about 30 seconds.


Press the power button to turn on the computer.

If you get an error screen upon startup, choose to restart Windows normally.

This error is caused by improper shutdown procedures.


Hope this helps

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.
