Power light flashes

Hi, I hope you can help me solve this problem. For the last 72 hours the power light on my apple LCD monitor flashes 3 times, then no light for 5 seconds and repeat, constantly. The monitor looks good, but I'm wondering if it's trying to tell me something horrid is about to happen.

    The monitor LED does sequences of 3 flashes.
    I have a G4 Apple Cube with 15" LCD Monitor.
    I wonder what this means.

I have an older 20" display. I have had this same problem on occasion, and coincidentally, just experienced it again this morning. It seems to occur after I do an OS update. I powered down the computer, disconnected the display, reconnected by pushing firmly into place, then powered up. The flashing stopped and the display works fine. You might have a different problem, but that simple solution worked for me.

Power light flashes continually but monitor will not work. I leave computer on at all times but turn monitor off. I did that last night but today it was flashing and won't come on or off. I tried turning...


Yes. Flashing LED with no image on the screen is the first sign of the power supply gets overloaded. That may be caused by blown/shorted electrolytic capacitors. Open the monitor, take metal lid off and observe for those caps which are rounded on top. Replace them with proper ones.

White flash/flicker on Powerbook G4 LCD monitor


There might be an internal device in your computer that is causing this, I have a 4 year old G4 myself, and a defect right hand side light sensor both caused purple stripes on the screen and made it go to sleep mode every time left hand side light sensor was covered.
You could run a hardware test on it: http://www.info.apple.com/support/aht.html
Maybe you could try to deactivate the light sensors in System Preferences?
These are more suggestions than a solution, but maybe you could start there. Good luck, I hope you get it solved!

Flashing green power light - Black screen


I had the same problem with an AOPEN 17' lcd that was left behind at a rental property... I plugged it into my dell dimmension 4400 in place of my old analog. It worked fine the fist night, and got up and when turned it on again it had the famed green blinking power light. I switched back to the analog, and just disappointed I plugged in the AOPEN to another power source, and power came on a steady red light. I plugged it back into the puta and it came on again. I have not turned the monitor off again for fear of the blinks, and has been working great for close to a week now. Hope it helps someone else out there. Richard

Apple Studio Display Flashing Power Button


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.

Acer AL1715 17" LCD Monitor


Certain versions of the Acer AL1715 monitor had a problem with the VGA socket. Specifically, the plastic case around the socket was not wide enough. The plastic interfered with the plug and so the plug did not seat properly. I fixed several of these monitors by shaving off some of the plastic with a dremel mototool. A hand file would probably work as well. You have to remove the plastic back to do the job.
