How can i fix my apple model a1082

SOURCE: Apple 23" Cinema HD Display went off

Hey - I just got done with 30 minutes of trying my cinema HD on my macbook pro and plugging and unplugging. When I plugged it into an extension cord in another socket the monitor started right up. I've had this configuration in my office for years with no problem...until today. Did mac send us a system upgrade that caused a problem with the monitor's power source???? Good luck!!!!

thats supposed to mean theres a faulty powerbrick, however i have the same problem on mine and replacing that didn't solve it

SOURCE: Apple Cinema Display 23" HD - Dust on inside of screen.

The dust in a can will ruin a computer because it only blows the dust around. Use a vacuum cleaner or a dry vac to get rid of dust.

The only solution to your problem would be to take the screen apart and clean the dust out.

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.
