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.
Jonathon401, You will need someone to evaluate the symptom. I can only guess that the upper Cold Cathode Fluorescent Tube or the Inverter circuit (a electronic ballast) has partially or entirely failed. The reason you can still see stuff up top could be due to light (bleed over) from the other 1 or 2 CCFTs hung horizontally on rear of lcd panel. Apparently they and their individual and identicle INVERTERS are still functioning. Please tellme more about the little light at the corner of the screen. Is it a ICON that looks like a flashing light bulb? Do you know if this monitor has on screen firmware to display a blinking light on the actual screen? Check with APPLE and see if they do swapouts of these lcd monitors. you send them yours+$40-$90. They send you a same model refurbished lcd with new CCF tubes and/or/maybe? rebuilt inverter ballast board. I'm louie12fix on fixya or lmistyrel@ aol.com Let me know how you do with APPLE.
