My Apple display power button is flashing short-short-long. I know what it means and I checked everything and everything seems fine. What can I do to ensure everything is really fine and the flashing stops. The computer and the display worked fine for over a year. It started doing it when I switched my computer off using the power button on the display. it never happened before.
thanks!
Mac OS X (10.5.8)
I know of no way to stop it short of repair, I do believe it's the Backlight, or more likely the Inverter, my 17" ADC/LCD has been doing it for years, but still works.
Do you still have AppleCare on it/them?
What you might try is unplugging the monitor at it s ADC connexion to the video card and the plugging it back in - all with the Mac turned on and everything working (and flashing).
I had an LCD/ADC flatscreen monitor that would dim the top half of the screen and start flashing whenever I would run Disk Warrior or Applejack or switch to a different startup drive. Simply unplugging and replugging would return it to normalcy - for days or weeks - but sooner or later.... Grew tired of waiting for it to go altogether and bought another monitor, but I tried it the other day on a spare Mac and - sure enough - it started up dim and flashing. Remedy was the same: unplug and replug the ADC connexion and it was back to normal. No idea why!
No guarantee, and no idea how long it might last, but the effort is small and the price is right.

hey, this actually worked! now I'm anxious to see how long it will stay like this.
thanks!

it worked until I restarted. and it flashes again the same thing.
it's driving me nuts
Does it do it if you just sleep/wake it?
no, it's perfectly fine until it reboots
Maybe a piece of black electrical tape over it?
what do you mean? if there is any or that I should put some?
I was thinking, that if it bothers you too much & requires some kind of repair that isn't going to happen, then covering it up might be at least a solution to the blinking light.
well, that's true, but it freaks me out that it's trying to tell me something is wrong. shutting it up doesn't seem to be the right solution 🙂
Yes, I quite understand, but then some repair is needed I believe. 🙂
